E85 Users, What oil are you using (brand/wt)
 

I've been on E85 for all of a couple days, I've been using Mobil1 0w20 since purchasing my FRS and I'm about due for an oil change. Was just wondering what the majority is using with success, from what I've read it would seem that Amsoil is the favorite.
Thanks!

I use Puroil. They assured me it was good for e-85, both street use and track days.
When talking with Redline and Amsoil they did not give me answers I was looking for.

Any SN rated oil is technically E85 compatible, I personally use Toyota 0w20 because it's shown consistently excellent results on UOA for this car. It's also a group 3/4 mix oil which is awesome for the price paid.

One guy on the forums posted Castrol 0w20 full time E85 uoa on 7000km and it looked excellent (in relation to fuel dilation and metals)

I run oem oil still on mine,

I use Redline 40WT

i use 0w-20 royal purple

Anything rated ILSAC GF-5 will be okay with E85.

Torco 5w-30 SR1-R

Edit - I wanted to also add that Torco starts off with a group 4 base oil and put fewer additives. I also have Torco diff, and transmission fluids.

From my basic understanding most companies start at group 3 and get to group 4 type with additives.

Not exactly. The base oil doesn't change with additives and most base oils are actually blended to create the final product. With the advances in Group III base oils over the years, they actually perform as good or better in some categories compared to Group IV's. Google Mobil's Visom and Shell's Gas To Liquid.

The whole "which Group is best" is outdated anyway. It's the specs that matter most and if a Group III can meet the toughest VW, Porsche, and MB oil specs then that's good enough for me!

Just to redirect the thread, my OP was not asking what is okay to use, there are a few threads out there already containing that information. This was created to simply get somewhat of a sample of what (brands/wht) the e85 community is using successfully. Thanks for those of you who responded thus far!

In that case, I've been using Mobil Super Synthetic 0w20. But I'll be switching to 5w30 for summer track season.

This one?

Yes, only I use 30 weight instead of 20.

I use Penrite enviro+ 0w20 and change every 7500km.
