What type of oil to use when running E85?

[gtrej01]

Hello, first off I did do some research on Google and here on the forum, nobody had a solid answer as to the oil weight to use when running E85?

I just recently picked up this my 1g and just finished doing the body work and paint on it and now I am giving it a full tune up before taking her to the track for its first runs since I bought her a month ago.

I have 5 quarts of 10w30 full synthetic oil sitting in my garage now and was wondering if that oil is OK or different weight?

The most popular oil weight I found when researching was 20w50.

What oil do you run when using E85?

Pardon me as I don't run e85, but why, according to you, does it matter about oil when when talking about fuel?

I personally do use and suggest Rotella for your choice of oil. It has high anti wear properties and is very affordable.

20/50 standard oil change it every 1500 miles or so

Valvoline vr1 is compatable with alcohol fuels.

Fuel contamination. It happens with every fuel. All used oil samples have some fuel dilution.

I just new to running E85 and was wanting to know if there is a difference in what oil I should use. that's all.

Thanks for the recommendation.

Thanks!

I run the Brad Penn oil in the 10w-40 and change it every 2500 miles. Its some top notch oil and looks great when it comes out after 2500 miles.

Thanks for the info, I wasn't aware that some oils were not compatible with alcohol contamination.

Stock vehicles that are E85 swappable (flex fuels) still use 5w/30.

Kinda worrying about nothing here ... stuff ain't gonna kill the motor as long as it still can make any surfaces slippery.

I've heard some poeple run diesel truck oil 20w50. they say it holds up longer,so you dont have to change your oil every 1500 or 2500 miles

I wouldn't run anything thicker than 15-40.

Amsoil Dominator 20w50 is alcohol compatible and a friend has proven it to me running it in his circle track car. He can run 2 races instead of one without changing and not near as much oil in the catch can.

I've ran conventional 10w40 castrol for awhile now on e85 and it runs just fine.

Reading my mind. I don't wanna get caught up in the 20w50 debate again, but I don't go thicker than 15-40 either. Then again, I don't know if Rotella has any gimmicks going aimed towards e85.

I am running Brad Penn 20w50 with lucas...

 

[FonZ454]

I like the Rotella 15w40. Cheap and I change it enough.

Fun fact about e85 - Toyota Tundras with e 5.7 e85 motor, right from toyota - if running on gas, oil changes are done every 5k - if on e85 , every 2500. Definitely play it safe with your oil.. I don't see the point of spending high money on synthetic oil when you'll be changing it often.

Another vote for rotella 15/40. Great, cheap stuff. no need for synth, unless of course, your road course racing where oil temps get out of control.

Yes, the oil does get dilluted with the fuel over time, more if running richer. Since you use more fuel running alcohol, it gets dilluted quicker, so you need to change the oil more frequent using alcohol.

Brad Penn 20w50

I've been running E-85 and Rotella 15w40 for 2 years now. Motor looked great when I had it apart a few months ago. Good looking bearings and no abnormal wear that I could tell. I do change my oil every 500 miles I figure, what's $20 every 2 months when I have $4k in my motor?

Just a question. Wouldn't the alcohol evaporate?

Just a question. Wouldn't the alcohol evaporate?

I'm not a chemist, so i can only go off my experience running an alcohol powered drag car. After each race event i would change the engine oil, and noticed that the oil had a strong smell of alcohol and there also was water in the bottom of the pan.
I assumed the water was coming from the alcohol and pooling under the oil because the oil temp wasn't high enough to boil out all of the water.

Fuel wash down.


Alchol breaks down oil faster than gasoline. Use your preference of oil and change it more often
