Oil content and % methol alcohol (nitro)

so which is better to use?

HPI ? 20% with not over 12 oil lube factor. My 2 best sellers are Bluethunder 20% and WERKS 20%................I use WERKS for my own trucks and cars[:-]

Sport if you are just driving around the house and don't want to spend a lot on fuel. Race if you want a bit more power and don't mind the added expense.

The "sport" is what I used to run in my bashers; it is too high of oil content which resulted in gummed up and slipping one way bearings. I had to disassemble and clean the engine thoroughly every 6mo to prevent the slipping (actually, I probably had to clean the OWB more often). The "sport" is by no means a sport blend at all; just a cheap blend marketed for the bashers.

I never used the race blend; but if it is actuall $2-3 more, it better ontain way less oil and be actually bleneded to compete with other race proven fuels such as Byrons.

What could you possibly be confused about?[8D]

The sport stuff also contains a additive that coagulates the fuel if your engine gets above 300 degrees I think.
