I got my 06 Accord's oil changed when it was 65k miles and now with 69k on the odometer, the car said I still have 50% left! wtf. With my old Civic (Same year, 2006) it would be around 20-30% right now...

Going at this rate, it seems like I only have to change my oil every 9k miles? That's a lot for conventional oil/filter. I'm so used to changing it @ ~6k miles for my 06 Civic.

I follow Honda's recommendation. You don't need to change oil every 3,000 miles anymore. My 03 Accord doesn't have the oil monitor, Honda writes in the next service on the tag in the windshield. With my '08 Element, I drive it until it says 15% and the wrench is displayed.

Even though the Civic and Accord are the same year, they are different engines with different requirements.

I tried 5000, but my oil looks too dirty.

Now I do 4000.

Unless you are a taxicab driver or drive all day up and down roads in a quarry, 3000 miles is overkill. However, most quick oil change places will try to scare you into 3000 intervals........

Used to do the recommended 10K oil changes (in less than 6months because of the miles I drive). I now do 5K since the oil is dirty and uses more than a quart up till then. I do my own changes for the reason of the scare tactics and trying to practically rebuild the motor every oil change. Hopefully I wont pay the price for the long 10K changes down the road.

I used to change the oil every 5,000 miles with sync but I am going for 10k miles with sync oil and bigger M-1 oil filter. My Honda Accord is doing 80% freeway.

I go with 10,000 mile OCIs. I've used Mobil 1 0W-20 and Mobil 1 filters every oil change since new. Everything I've read suggests that Mobil 1 oil is nowhere near its breakdown point at 10,000 miles, and my car doesn't burn any detectable amount of oil in 10,000 miles.

06 and newer accords have maintenance minder which does a ton of calculations to tell whether it is time for you to change your oil. Its completely different from the mileage-based monitors. It monitors the number of startups, idle time, acceleration rates and many other factors.

So my maintenance for my car ranges from 5000 miles to 9000 miles depending what kind of driving I do the most during that period.

With my other cars, I'd change my oil about every 3K miles.

With my 07 Accord, I just wait until my maintenance minder tells me that it's time to change my oil. Probably because of my style of driving, I've changed my oil roughly every 7K miles.

The only way to know how long your oil can last is to do a used oil analysis (UOA). I have mine doen by Terry Dyson (www.dysonanalysis.com), a very good guy who knows a lot about Hondas, he's very knowledgeable on the infamous fuel dilution problem.

I have run both Pennzoil Platinum 5W-20 and RLI Bio-Syn 5W-20 in our 03 Accord I4 AT. We do about 70% highway driving. Both oils did very well, low wear rates, held their viscosity, but the additive packs were depleted after 8,500 miles. That's the change point for our car. If I was driving mostly city I would change at 5,000.

The RLI 5W-20 is outstanding. Costs about the same as Mobil 1, even lower wear rate, made with high oleic vegetable oil as the base stock, with similar additives for PPD et al. Recommend it to one and all, made in Ohio, from plant oils made from American-grown crops. www.renewablelube.com

Dont forget about the amount of time the oil is in your car. Just because you didnt drive 5k doesnt mean the oil doesnt need changing.

I try to keep it around 4k myself although on my most recent oil change I got sloppy and forgot about it and pushed it to 5k :dunno:

3.5k or 4k, no more than that. Having the oil too long in the engine regardless what manucaturer (Honda or the oil/filter) will damage it. Think about this: you go to a fast food X and the french fries taste different everytime you go there, yet they are the same brand. Want to know why? New, clean cooking oil boils faster and cooks cleaner. Same oil after 3 days in the deep fryer: for sure the taste is different.

What ad from an oil company? That is a used oil analysis from the premier oil site on the internet. Oil is oil? You should go there often to learn......very often.

I don't advocate leaving oil in an engine for five years but that oil analysis just made total bunk out of your "french fry" comparo. The entire idea of a UOA is to determine the condition of the oil and that one showed .3 insolubles. There is no crud in the oil or under the cap, it would have shown up.

Oil is not oil. That is far from the truth. I know for fact that my oil analysis from blackstone says I can leave the Motorcraft 5-20 in my motor a lot longer, but I don't b/c of Toyota's stupid 5k OCI. Once out of warranty...it will get M1 and I will go lunch longer.

Now that I work 60+ hours a week...it is nearly impossible for me to find time to change my oil (along take it to someone on the weekends) so a longer interval would be nicer. Makes me miss the Acura and its roughly 8k oil changes.

I just had my 1st oil change at 4000 miles when the oil monitor read 50%. I was going by the old standard of changing the oil every 3500 miles. I didn't realize until I read this thread that you could let it go 20-30% - Honda's recommendation?.

Excellent point, if you're going to eat anything cooked in engine oil.

FWIW, the way to know if changing engine oil every 10,000 miles is bad for the engine (outside of independent oil analysis, of course) is to talk to/reference people who have done it for many miles.

I bought my '01 Odyssey and my '03 Accord new. I have always used Mobil1 and changed the oil at 10,000 mile intervals on both. The Oddy has 160,000 miles on it, the Accord 130,000. So far, they don't burn oil between oil changes, nor exhibit any engine problems which would indicate problems. Now maybe I've just been lucky. Personally, I trust experience and the manufacturer's engineering knowledge over someone making cooking oil analogies. Your mileage may vary.

This issue never seems to go away. Climate and driving methods should dictate. My preference is at 3,000 miles I change the filter and top off, at 6,000 mile interval I change everything. No matter what I put a new filter on. I use either a Mobile 1 or the top Purelator filter. As far as type lube, synthetic, Mobil 1 o Royal purple. The interesting thing is, that usually at 3,000 miles my oil life indicator shows 50% life remaining at 6,000 miles about 5%. So my question is this, is the car monitoring the condition of the lube (based on how the car is driven i.e. RPMs) or is it just another nice to have indicator?

RTexasF
01-22-2009, 02:45 PM
The computer uses a great deal of information to estimate the oil life. Honda & GM oil life monitors have proven to be quite accurate. Yours is set for standard dino oil not synthetic so there is some safety margin built in when using synthetic oil. If my car had one I would trust it.

Aceman196
01-22-2009, 05:29 PM
I would rather change my oil regularly to be safe. Obviously the oil becomes thicker the longer it stays in the engine.

rstern753

I have an '89 Accord with 226k+ miles. My oil change interval has always been 3000-5000 miles. The shop I use, which is a Honda/Acura only repair shop, uses Castrol GTX. The engine burns no oil, and blows no smoke. It doesn't quite have as much power as it did when it was new, but it runs like a top.

I just purchased a 2006 LX 4cyl with 28k miles. I will ignore the reminder and go with 3500-5000 mile intervals. My shop charges me less than $40, they completely look over the car while it's in, and since I drive <10k miles a year, it's no big deal.

PanzerLeader
01-22-2009, 06:20 PM
If I were still running dino, I would use Castrol GTX. Never had I problem in any car that I used it in, no matter what model. (280Z, Honda or Infiniti)

I change my car's oil at 5k intervals. Usually it ends up twice per year. I'd go longer if I'd have stuck with Redline 5w20, but economic issues have made me switch to Motorcraft 5w20.

I use the Redline in my Lightning and it gets changed every 2 years or so. I don't put many miles on it and when I do I always make sure that the oil temp is brought up.

On any car that's primarily used almost continuously, say a livery car, taxi or even a police car 10k or more isn't an issue. Keeping the oil at a good temp of 212 to 240 is a good temp to burn off any condensation. At the limo company I used to work at, we hand many gas powered cars go 30-50k OCI and all of them easily made 600k to 1mil miles. Cold starts and short trips kill the oil and engine, as well as running too hot.

Even now, many on-highway fleet diesels are now not changing unless indicated by analysis. I've read of some going 500k on actual sump drainings. Every 20-50k which many newer electronic diesels call for service, they change the oil filters, and top off. The top off renews the additives lost. Usually the filters alone in one of those trucks can hold up to 4 gallons. The same goes for many fleet air filters, they all use restriction gauges and properly sealed housings, 500k to 1 mil on air filters in on-highway use isn't unheard of.

rafael73
01-23-2009, 04:20 AM
It seems that more people do the change between 3k & 5k which it is more logical. Everybody is free to do and think what they want. Me for example, I don't pay for the ol change on both cars. Dealership does them for free due to a promo that I took advantage when bought the vehicles. And they use Castrol GTX.

As you can see, since I don't have to worry about that expense (already prepaid for 6 yrs from the purchase date) I do it at lower intervals. And from my end, that will be the last comment on the subject. :banana:

As far as I've ever read, no one has ever done damage to their engine by changing the oil too often; changing it every 3000 miles makes no more sense than changing it every 1000 miles - but it doesn't hurt a thing.

No one with any sense is trying to get people to change their minds and use longer oil change intervals; there's no reason to try to change minds.

When this issue comes up (quite frequently), the question is posed by someone who *hasn't* made up their mind, and is looking for information. Telling them that changing their oil every 3000 miles doesn't cause any problems is true, but it doesn't provide information. When someone asks this question, they are trying to find out how safe a longer interval is; nothing else makes sense. No one asks this question because they doubt that a 3000 mile oil change interval will damage their engines. At least, in all the years I've seen the question, I"ve never seen that.

My (long-winded) point is that if you are telling the questioner you're changing oil every 3000 miles (I actually *have* seen people claiming to change it every 1000!), tell them why. Otherwise, you're not providing any useful information.

Once again, for the originator of the question: the way to tell for your individual automobile is independent oil analysis. That's neither convenient nor cheap; a cheap and convenient way to *estimate* is to use the manufacturer's recommendations. A somewhat more informed method is to ask people who have used longer intervals what their experience has taught them.

I dont see why you guys like to do oil changes so frequently whether its 3 to 5k diy or at the dealership. I'm lazy and do 10k with syn oil. I've never done a UOA and dont plan to as I trust Castrol Syntec, PP or whoever to do their job. Plus I dont want my car to own me service wise with time, driving to the dealership or dumping oil somewhere.

I personaly trust Honda. They have a reputation for building great engines, so I think they no a thing or two about engine maintenance (at least more than me). If they tell me to change it every 10,000 miles...so be it.

Of course the oil is going to get dirty...that's part of the job...dirty doesn't necessarily mean ineffective.

I imagine if you did a seach of multiple Honda forums, you wouldn't find many (if any) engine failures do to Honda scheduled oil changes.

Civic probably has less oil in it. My Accord took 4.5 quarts and my friends D17 Civic took 3.4...maybe that still holds.

I go by the MM and schedule the oil change after it hits 15 percent (I also prefer to see which MM codes will pop up in each interval so I can do the appropriate service and/or checks).

First oil change was at 5,794 miles. Second oil change was at 12,227 miles (6,433 miles on that oil change). I'm currently about 3k miles into my last oil change and the MM is reading 60 percent. I figure I have another 3k miles or so until I hit 15 percent. All in all, it looks like I'm running at oil changes every 6k miles or so for the most part.

There is so much bad information floating around about oil change intervals, it is truly amazing. People will do anything from 1,000 to 50,000 mile change intervals without any empirical data to support their decisions.

Modern engines are better and so are modern oils, which are designed to meet much more demanding OEM specs than in the past. Those are the main reasons why the oil change intervals are longer than in the past.

For most drivers, changing every 3,000 miles is wasting oil. Look at the many UOAs on BITOG, you'll see that many drivers are going 5,000+ miles in cars of all makes, and the oils are doing their jobs. Look at the data before throwing off comments like "leaving oil in the engine for a long time , it turns to sludge".

Data from Dyson Analysis

Here is real data from analyses by Terry Dyson of the oils from our car that I use to set our OCI in the 8-8,500 mile range:

And both of these are full synthetics, which just made the results irrelevant for 80-90% of the people out there.

Oil is cheap. Let people change it whenever the heck they want. I find no reason to let oil continue to the point where "ok it's dirty enough, time to change it" when I could just run cleaner oil and not mess with UOA's? UOA's are expensive and people's driving habits change. 100% of the Ody's driving is either city or 80MPH highway and the balance and also the time frame changes significantly between oil changes. So that's two UOA's already. My Mazda has seen at least 3 different driving styles just since May, that's three UOA's right there. And I suspect I'm not the only one out there that changes their driving patterns all the time :dunno: And we haven't even said that you pretty much have to stick to the oil you did your UOA on. I run PP and MotorCraft in both cars, depending on if I can get a deal - that just doubled my UOA's to 10. $25 a pop for UOA's when I could just change the oil between 3-5k depending on when it's convenient for me, and not having to deal with UOA's, and being able to sleep easier at night...I think that works better for me. Sure if I waited til 7K nothing would happen, I would bet my paycheck on it. But I won't have any of it in my car. That's my story and I'm stickin to it

STSinNYC
01-28-2009, 08:39 AM
Benjiboy is quite right that everyone's driving habits are different. FYI -correction for Benji- the RLI Bio-Syn is not 100% synthetic. The base stock is a type of vegetable oil.

In our previous Accord, we ran Pennzoil regular ("dino") 5W-20. UOAs on that showed it could run to 5-6,000 miles based on our driving habits, about 2/3 highway.

I stand by my point that most drivers can have some confidence in the manufacturer's recommendations on change intervals, which are longer today than in the past. The severe conditions recommendations are a reasonable starting point. I'm no crazy environmentalist, but if we use less oil over the lifetimes of our cars, that is in fact better for the environment, and we're using up fewer non-renewable resources -- another reason I switched to an oil made from renewable base oil stocks, plant oils.

Neither is the PP, it was switched to a dino based oil sometime after being introduced. But it's labeled synthetic so I call it a 100% synthetic since it performs way better than semi-syn or dino oils.

I'm still not inclined to trust manufacturers OCI's...if for most people the severe recommendation is a reasonable estimate, why does that regular interval exist, and why is it not called "regular" and "extended" then? It seems to me like they're trying to pull a little trick for lower maintenance costs - look at your own results, you're running synthetic and you can't even get to the 10K interval they recommend for most owners in the manual (assuming 4cyl). UOA's I can trust, but again they do cost money...

STSinNYC
01-28-2009, 05:55 PM
Our previous Accord was an 02 V-6. Pennzoil dino could be taken to 6,000 before TAN and TBN approached the limits (with Lube Control added to address the fuel dilution problem). Our 7th gen Accord 4 cyl. can reach 8,500+/- with the RLI formulation before the acid fighting ability is depleted and the TBN gets too low. You will see other UOAs on BITOG showing similar results

I believe UOAs are worth it for this very reason, learning the actual changes in the oil chemistry. I don't think you need to do them for every change, I don't. You learn important details, such as the level of fuel dilution, a well-know problem with Honda engines, and if any coolant is leaking.

The learning from the many UOAs from Honda engines indicates that Honda owners can go farther than 3,000 miles on their oil changes on properly maintained engines. How much farther is the "depends" question.

My '07 V6 has had 70K miles put on it in 24 months. The MM usually calls for the oil to be changed beween 7500-8000 miles.

I run Valvoline Dura-Blend 5/30 semi-synthetic (picked up 72 quarts free after rebate at the same time I bought the Accord :thmsup:) and after the factory dump at 6500 miles, the intervals have been between 7500 and 8900 miles; averaging 8100 miles.

Due to the car being driven for business road trips constantly, I don't always get to change it right away. I believe the semi-synthetic oil affords a bit of a cushion.

No engine worries at all...wish I felt the same way about the transmission... :paranoid:

For the Accord, I do it when the MMS is down to 5 or 10%... whenever it's convenient for me.

For the Pilot, I follow the normal maintenance schedule, which means 7500mi OCIs. I had a UOA done the last time, which indicated that I was pushing it a little. I switched oil brands and will do another UOA at the next OCI. If it still shows the same results, I'll either switch to 5-6k mile OCIs.

BTW - I normally use conventional oil for both vehicles, but I picked up a few cases of Valvoline full synthetic when it was on sale recently, so I might give that a try on the Pilot while still following the normal schedule.
