I've always ran a high oil content fuel with great results over the years. I always ran byrons 20% with 16% oil. Then I took sometime off and ran traxxas. Traxxas was way too oily for my taste and now I run byrons rtr 20 with 16% oil in all of my rigs. I would run the Odonnels race blend but 8% is just not enough oil in my opinion. Just remember if you change fuels, you most likely have re tune your engine due to the oil content and additives being different.
