What do you think of the Ester based and group 5 oils? I am going to build a big block for my car, and I will run RS55 9.

Esters are base stocks that date back to WWII. Several different kinds common ones are diesters, polyol, and phosphate.

Diesters have the ability to function over broad temperature ranges, thermal and oxidative stability and exceptional inherent lubricity.

Polyol have the same broad operating temperature range as other synthetic base stocks and exhibit good thermal and oxidative stability.

Thanks for asking a good question made me go back and look at material that you read that most people don't care about! I think that since your asking about esters and groups you have a good idea what to look for in oil!
Give the Z-Rod a try it is for performance engines.

What would you recommend for the following application:

437" SB2.2 approx 750-800 hp on E85
Intended usage is road course and autocross but be able to drive on the street as well

Thanks

Sweet motor you have in your car!
I would run the viscosity recommended from the builder in the Dominator racing oil.

You can find this oil and more information on my website www.jacobehlers.com under motor oils and sub catagory racing oil. Let me know if you have any further questions and I can tell you how to save 25%.

I would also recommend bringing oil analysis into your program. Lots of people guessing when lubricants need changing. Aside from that it tells you what is wearing inside your engine and could catch a problem before failure.

OE fill in that engine would have been VP Racing oil. I would stick with that depending on who built the engine.

Excuse me a moment.....................:lmao: :lmao: :lmao: :lmao:

:thankyou:

I would be most concerned about viscosity.
