RE: OS 1.08 Nitro engine
I'm not brand loyal at all when it comes to fuel, whatever is on sale. Usually Power Master or Wild Cat, I do usually buy 15%, one fuel does it all. To date I have never seen an engine harmed when using any brand of store bought fuel. I do prefer blended oil though but full synthetics work just fine, it's a choice thing. The 1.08 OS was one of there all time best!!
