So, I was on FP's website and they give a nice little write up and list of oils that they like to see in the 4g63 and the FP turbo's . I have a 2.3L FP Black built motor and the question that I have is what is better type of oil to use with E85. I am leaning towards the AMSOIL Dominator series oil but just seeing what others have found or learned. Royal Purples XPR looks promising as well. This is the first oil change on this motor since the build in which they used the AMSOIL SAE10w-30 Synthetic. Thoughts?

Many people here live by AMSOIL and i have to agree with them. Ive also used Valvoline Racing oil recommended by AWDmotorsports. As for using with E85 any of the recommended oils on FP's list should be fine. When i was working at Chrysler we didn't have any specific oil of our E85 fleets vehicles we used regular Pennzoil 5w20 and they ran fine for 200k miles of abuse by the employees

Also there are some great threads in the sticky sections i highly recommend the filter thread

super informative on a crucial aspect of any new engine build as there will be particulates floating in the oil from break in

Yours is a very good question. The issue with E85 is that unlike gasoline, it creates a phase separation with oil that creates sludge, or in extreme cases, a strange goop to form in the pan as some have witnessed. Many oils (but not all) have been upgraded to keep E85 from separating over the long haul. The latest API SN and ILSAC GF-5 standards reflect this change.

Here are several popular synthetic oils that meet both API-SN/ILSAC GF-5 standards for E85 compatibility and contain at least 1000 ppm ZDDP. For those with an FP Red or Black, I would stick with 1200 ppm ZDDP or better as per FP's recommendation.

Mobil 1
0w-40 (1000)
5w-40 Turbo Diesel Truck (1130)
10w-40 High Mileage (1000)
Racing 4T 10w-40 (1200)
5w-50 (1000)
15w-50 (1200)

Amsoil
All automotive oils are formulated for E85 compatibility.
Z-Rod and Dominator series are formulated with elevated (1200+ ppm) ZDDP content.

Royal Purple
Standard oils are API-SN licensed and compatible with E85.
HPS series feature elevated ZDDP (1200+ ppm) and formulated to be compatible with E85.
XPR series feature elevated ZDDP (1200+ ppm) and formulated to be compatible with E85 + exotic and corrosive fuels.

Valvoline
VR1 features elevated ZDDP (1200 ppm), only 20w-50 grade API-SN licensed.

Undoubtedly there are others, but this should be helpful.

Thank you, this is very helpful in my case and anyone else that may be looking.

My builder recomends 15w40 rotella for e85

Are you sure about the 15-40 rotella? That's dyno oil.

The synthetic one is 5-40 rotella T6 and is a great oil.

...and I guess this leads me to my next question. Since I don't drive my car in the winter, what weight is suggested? 5-20, 10-30, ...

This is a regular conventional oil, intended for diesel engines, and is not formulated to be compatible with E85.


It is a better option because it is a synthetic, but is also formulated for diesel engines that won't ever see E85, and does not carry an E85 compatible rating.


If you're not driving in freezing ND weather, there is no reason to use anything with a cold viscosity index of <10 (e.g. 10w-40, 15w-40, etc.).

yes, built by jacks transmissions

I don't know if you tried the AMO 10w40 but this oil has held up well to nitrous, ethanol and race fuels

2.3l FP green here and using VR1 as mentioned above - also recommended by my builder.

Looking closer atn your build and I am sure your engine builder MAP reccomended for you to use Dominator. .. they are correct. . It will be a very wise choice for you with the 2.3 and FP black
