Those of you who run e85 in your car, what type of oil do you use and why? How long do you run the oil in your car before you change it ? Thanks in advance

 

Mobile one full synthetic. 3k miles 10w30. Track and street.

 

Have you ever tested your oil with that many miles ?

 

I only use Mobil 1 and im kinda picky so I change my oil every 2k and everything is clean, I have 5qts of Amsoi and an Amsoil oil filter for my next oil change just to try it. Read this!

Nope and I'm not gonna worry about it and I'm certainly not going to change it any more often than that. I think if you start changing the weight and all that you are probably doing more harm than good.

 

Thanks for the replies, I just asked because I read a lot of bad things about mobile 1, there formula change, I usually run vr1 or. If im patient enough to wait for it amsoil dominator series, I've been thinking of trying their zrod formula next anyone with any experience running this oil

 

I run zrod in mine and have zero issues. The zinc in my opinion in zrod is extra protection. I change my oil every 3000.

 

I run mobil 1 too.only thing I noticed it burn more oil on e85 then on regular 93.

 

Brad Penn 20-50 with built motor, I change it every 3000...

I did run the Amsoil Z-Rod 20-50 for around a year, but it gets pretty thin compared to the brad penn...

 

I run Amsoil Z-Rod 10w30 and change about every 3,000.

I would recommend a proper baffled catch can when on e85. Running e85 can create some contamination in the oil quickly. I run 20-50 Vr1 and have heard great things on Brad Penn oil. Depending on ring gap and how well your engine is sealing 1500-2000 miles if you beat on your car often. Its cheap insurance.
I'd also recommend a tank of regular gas every so often to cycle thru the system. I know in the southeast the fuel contamination can be an issue with the humidity.

 

I run brad Penn 20w50 or vr1 20w50: change it every 2500 miles or two months. Mostly gets changed every two months lol

 

I run Mobil 1 EP, change ~ every 3k. Motor has 140k on it. I have been running E85 for the last 40k miles.

 

137k miles, daily driven e85 (~430/380), mobil 1 HM 10w30 every 2.5k miles, 150 152 151 152 compression (checked 1k ago).
