Hi, i have a question about using after run oil. i have a rs4 evo, with stock t- 15 , that i have been running 30% (sidewinder) fuel in. On the back of the sidewinder fuel bottle it says not to use after run oil with this fuel. I have a 705 serpent with nova mega .12 in the mail as we speak right now and i wanna make sure that not using the after run oil with this new car will be ok. I have had no probs that i can tell with the rs4 engine since i have had it. your comments and input would be helpful thank you.
