The computer does not analyze the oil it just records data. Adding oil wouldn't have any effect on the percentage of oil life remaining unless you reset the system by accident. If you ran the hell out of it and it was a quart low in 2,500 miles it would be nuts to have the oil changed. Just add a quart and go on with it.If your oil level is down, don't top it off. This causes a prolonged oil life, which means you will be using contaminated oil in your engine for longer times. If you see the oil low, drive somewhere to get your oil changed, or do it yourself.
I never said anything about it "analyzing" the oil itself. It only calculates it based on driving habits(as I mentioned in my original statement), and if it's too low, the maintenance minder will notify you. I was also referring to visual inspection...I guess you somehow missed all my points, since you cleverly forgot the sentence before the sentence you quoted me by:dunno: If your engine is that low on oil, it's for a reason, and chances are, it's going to be dirty as dirt!!The computer does not analyze the oil it just records data. Adding oil wouldn't have any effect on the percentage of oil life remaining unless you reset the system by accident. If you ran the hell out of it and it was a quart low in 2,500 miles it would be nuts to have the oil changed. Just add a quart and go on with it.
It was probably assumed since you saidI never said anything about it "analyzing" the oil itself.
The above statement is also a bunch of hogwash. A visual inspection of oil will not tell you whether the oil is good or bad and needs changing.This causes a prolonged oil life, which means you will be using contaminated oil in your engine for longer times. If you see the oil low, drive somewhere to get your oil changed, or do it yourself.
Not it doesn't. The maintenance minder should only let you know when certain maintenance is due.if it's too low, the maintenance minder will notify you.
Hope this "engineer" didn't tell you all this.Helps to have an engineer in the family who's been working on building engines that are a small as a minibikes, to as large as a cargo ship's.
No, I actually made a mistake by grouping the maintenance minder in with the oil pressure indicator. By measuring oil pressure, the computer is essentially measuring oil levels, along with a possibility of faults in the system. Oil pressure sensors don't have a habit of breaking easily, so if your oil light is on, it's probably due to low oil pressure=low oil levels. I haven't read anything on this regarding the new Accord, but some cars have an oil pan level sensor that gets triggered if the level is too low. As far as I know, though, the new Accord i4 only has an oil dipstick as a visual oil level sensor. I made a mistake called the oil light the "maintenance minder." They're obviously two different things. If your oil level is low, the low oil pressure indicator will light up.and if it's too low, the maintenance minder will notify you.
Please help me out here.(no enginer in my familly)Are you saying the "Maintenance minder"has an oil level sensor in the engine?
Of course there are exceptions. My Passat was an oil hog. I had the oil tested a few times, because I wasn't sure if I wanted to buy it out after the lease do to it "burning oil." The tests required fresh oil, along with running oil samples. I was using Castrol full synthetic approved for VW. Though the oil looked visually clean on test paper, the test showed higher than average build up of carbon, and lower than adequate levels of zinc. Low quantities of zinc mean the oil is now insufficiently doing it's job at preventing wear, or reducing friction of metal to metal parts. If you were to "top off" oil in this case, you would be reducing the amount of zinc available to adequately create a buffer between metal to metal contact, because it now gets diluted in with the old oil. It's not good, and you're only prolonging your driving abilities for a short bit.I agree to disagree,different engines burn more or less oil(specially when newish).I dont see how would you contaminate the oil in your engine by adding a fresh 1 qt.of oil
Hi :naughty:, nice to meet you to:wave:It was probably assumed since you said
Not at all. You are prolonging the oil life because you are diluting new oil into old oil, which means you will get longer oil life, but have that used oil in your car for longer times. The MM doesn't even matter because it doesn't measure the actual quality of the oil. Most oils are created with oil content that naturally darkens with wear. That's not to say a dark oil is bad, or is providing insufficient cooling or lubrication, though. The cleanest oil color is always the color that it was when you put it in. Any color shift after that is due to wear, and chemical reaction, or the contamination of leftover oil. Patterns of oil wear are noticed if you make it a habit of visually checking your oil, which the manual suggests you do. The more the oil wears, the darker they get. There are exceptions to this, such as heavy machinery that uses thicker, darker oil, but obviously, for cars, the saying has been consistent since cars got their first oil dipsticks: if it was clean when it went in, and dirty when it came out, your oil is dirtier than when it went in. You have to really want to argue to argue against that.The above statement is also a bunch of hogwash. A visual inspection of oil will not tell you whether the oil is good or bad and needs changing.
from my previous comment you quoted me from=Curious though. How does topping off your oil "prolong oil life" and cause one to use "contaminated oil in your engine for longer times?"
I guess you must have a seriously narrow mind of thinking.If your oil level is down, don't top it off. This causes a prolonged oil life, which means you will be using contaminated oil in your engine for longer times.
If you read my last comment, I somehow bunched up the oil pressure indicator and maintenance minder into one without thinking about it. Oh will you ever find it in you to forgive me???Not it doesn't. The maintenance minder shouldn't only let you know when certain maintenance is due.
That's a great comment, coming from someone who sure as hell didn't provide a lot of insight into anything.Hope this "engineer" didn't tell you all this.
You are prolonging the oil life because you are diluting new oil into old oil, which means you will get longer oil life, but have that used oil in your car for longer times.
Page 560 has additional info on what to do after you stopped. It said nothing about changing your oil or finding a near buy place to get your oil changed.Page 69. Immediately stop in a safe place.
I was looking for the same thing. Personally I think it would have been informative if Honda had noted in the owners manual that oil changes weren't going to be strictly mileage based and that's why they weren't specifying a mileage interval. But I also think it would have been helpful to give some kind of mileage range so people could know what to expect, after all, we don't want to get into the habit of just blindly trusting the car computer, especially since it's always possible it could fail and not give proper notification. It seems the only hard limit Honda was willing to put in the manual was to do oil changes yearly even if the oil life indicator is still above 15%, but I think they should have added some kind of range as a guide, maybe 5000-7500 miles, depending on driving habits, or maybe a maximum like 10000 miles. The same for other typical maintenance items, the first thing I look for in the manual is a chart of when they recommend various things be done or checked, but I haven't seen one, so they really are asking you to trust the computer, which may be ok but it would be nice to know you might have a big maintenance item upcoming so you can plan for it rather than being hit with it one day while driving into work. Funny thing about the owners manual I see is that almost 50% of it is devoted to how to use the nav/audio system, and so maybe they skimped on real car stuff in order to keep the manual from being even more huge than it already is.I can't find it anywhere in the manual or online..It just says when the reminder comes on change it.:wave:
:thmsup::thmsup::thmsup:It is always the engineers that make a mountain out of a molehill over thinking everything. If the frikkin car is low on oil just add some, it's really not complicated. As mentioned several times the car will tell you when to change the oil & filter.
LOL - the best oil is the one that meets the specs of the manual and is on sale at your local auto parts store. You can way overthink this - go to bobistheoilguy.com if you want to see overthinking and "discussion" by "experts"I won't dare ask whats the best oil
great post sir, a sane voice among the roar of the (enthusiast) crowd....I just retired from the auto service bizz and have a few thoughts on the oil subject. Every car, truck and motorcycle forum I've ever joined has endless discussions on oil and oil changes. Between engine lubrication not being well understood and the "mouse milk" marketing of oils and additives, it's no wonder there's such differences in opinions. Plus, there is a huge body of folk wisdom, old wives tales and plain mis-information to further fog things.
Here is my advice. On a Honda, with anything close to normal use, the MMI will give you a reasonable change interval. Use the recommended viscosity and service classification oil and any good filter. That's it.
Lubrication failures are pretty rare in the last few decades unless the oil leaks out or gets way too low from normal consumption and/or extremely long change intervals. Honda engines stay amazingly clean inside even with infrequent changes.
With these long change intervals though, be sure to check the oil level every so often. An engine that uses a quart every 3,000 miles will be almost 3 quarts low after 8,000 miles. That level of consumption is not that uncommon these days. Friction reducing low tension piston rings are commonly used today for better fuel economy and can allow higher oil use.
Another reason to avoid too frequent oil changes is the risk of having some cretin who shouldn't be allowed to work on a wheelbarrow doing a vital service on your pride and joy.
Now that I'm retired, I plan to use the MMI for most maintenance. I can't lift a car at the condo so I'll use a good independent shop I know about and bring my own oil and filter. The old grey headed guy who does lube and basic service there is meticulous and happy in his work.
