: Best oil?

I have heard numerous recommendations for oils to use in these old accords (Mine is a 92 LX AT w/154k). So my question is: Which oil performs best?

I've been using valvoline semi-syn for high mileage and havent been impressed. Thought I'd ask for others opinions before I make a switch at the next service.

I have not compared many, but I get amazing performance out of Kendall full synthetic with titanium.

What does that mean and what does it have to do with how well the oil is performing? The best oil would be the one that Honda calls for and is changed on a regular basis.

From one of the most knowledgeable people on here:

If it were my car I wouldn't be running that.

Castrol (as well as Valvoline) has had a recent history of not passing all of the specs they claim to "exceed".

Based on their product data sheets, the oil is slightly thicker than other brands at both hot and cold, and the colder it gets the thicker it is. Their 5w20 is actually much thicker at very, very cold temps than their 5w30.

It could be draining out of the vtc actuator more easily. It could be as simple as that. or not.

I'd be looking at the following oils:

Shell and their sister brands, Pennzoil and Quaker State. (both are owned by Shell)
The Shell oil is usually less expensive, but just as good.
Motorcraft Semi Syn 5w20 and other ConocoPhillips oils. It seems now that's who makes MC oil, as well as Honda's US factory fill and dealer oil.

Kendall is made by ConocoPhillips.

Its an older car. Which means the motor probably isn't in brand new condition. I work in an automotive shop and have tried all of the oils that are out there (basically). Best for higher mileage cars, DELO 15W-40.

This is a link that describes what oil Honda actually recommends in other countries for their cars.

"In the Malaysian market at least, Honda officially markets two grades of engine oil. The "Honda Engine Oil" is a semi-synthetic 15W-40 oil which is recommended for all Honda engines, including the super high spec'ed DOHC VTEC and DOHC iVTEC versions."

asmoil synthetic is number 1

Especially for finding all those pesky leaks in higher mileage motors.

I was always taught mobile synthetic 1 is the best balance of realistic $$ to protection

taught wrong

buy dino oil in the right spec - change it often - like every 5-6K - or when the MM says...all the attributes of synthetic are if you don't want to change your oil in 15K - or run a NYC taxicab. Yes syn protects a bit better at start up BUT NOT SO MUCH that a engine of 120 K is going to be a better engine...The truth is not THAT much..

The synthetics were made at the request of car mfrs that wanted to extend the oil intervals and also protect their lease cars (50% of what they sold) against idiots that never changed the oil....

The truth is we put syn in becasue we are hobbyists and want to believe that it's the best we can do for the engine...and yes, for years I used to be this exact way.....

People misunderstand the real point of synthetic, and get caught on the sales hype. The reason I use it is my engine will be cleaner at 200k miles than someone using dino.

The reason I use delo 15w40 is because my engine is cleaner at 275,000 miles than your motor.

Congratulations. I will stick with 0 or 5w20 synthetic, not adding significant carbon buildup.

Is it wise to use a weight of oil so far off from what the manual recommends?

Safe is to go with the recommendations. I understand what they're saying, and maybe on old super leaky engines, the higher weight definitely isn't going to hurt anything.

Did you read the link in my post? Probably not. Because Honda actually recommends the same weight oil I use. Delo 15w40 has improved the performance of my motor and everyone else who I know that has used it.

The oil on the right is recommended for vtec lev. The one on the left is for vtec and non-vtec honda motors. Hope this helps.

As for what manuals recommend, keep in mind that toyota lists incorrect torque specs for older supra turbo models. This is known to be the cause of a blown head gasket for these cars. There has been much research on this and there is a proper torque spec, which toyota did not list. Shows that you can't always trust what is in the manuals.

Also, my owner's manual for my 91 honda accord ex states to change the oil and filter every 7500 miles, but almost everyone will stick to the 3,000 mile rule. Try to remember, these are all recommendations, not requirements.

I did read the link and your post. Keep in mind you are recommending an oil that is used in HOT and HUMID environments. I live in Salt Lake City where winters can easily drop below 0 degrees and it is VERY dry here.

A heavier weight oil is harder for the engine to pump at cold temps which robs gas mileage and is NOT good for an engine in colder environments. It may work, but at what cost for where I live and MY specific driving habits?

I have been researching the topic on BobIsTheOilGuy.com as well as a few other sites and have found very useful info on there.

As far as I can tell 5w-30 or 0w-30 in a full synthetic is best for my environment and driving habits with an OCI of 5-6k miles.

Thanks for your input however. If I did live in a warmer environment, I'd probably give your recommendation a shot.

What motor-oil do I use? Whatever is on sale (namely, cash-rebate making it free)! :D

Oh yea, my regimen:

- synthetic for the Accord (0W20/5W20) w/ ~30k miles, changed @ MMC ~5% (usually ~7.5k+ miles) along w/ a high-quality filter (OEM/Filtech, Bosch Premium, PurulatorOne, Napa, Beck/Arnley)

- synthetic for the Acura (5W30/10W30) w/ ~75k miles, changed @ ~7.5k miles along w/ an original tall-filter (OEM tall-filter, Napa tall-filter, Beck/Arnley)

- dino'juice for the 'ute (5W40/10W40) w/ ~115k miles, changed @ ~3,750 miles along w/ a quality filter (Napa, Beck Arnley, Fram ToughGuard)

For the synthetics that I've used: Mobil-One, Pennzoil Platinum, Quaker State Ultimate Durability, G-Oil.

For the dino'juice that I've used: quality, high-mileage/durability blend.

FWIW, a clean air-filter is equally as important as your engine-oil. . .
