Un4racing- I will tell you this as I have run both fuels. I really had to lean my engines out when switching from odonnell to TQ. I've been running the fuel for 3 years now and it has been super consistant, always run cool with great gas mileage. It also has oil content that doesn't require afterrun oil every race like when you run odonnell, as the odonnell doesn't have anything to protect against mositure. If you don't keep on top of it running odonnell your engine will rust. I say give TQ a try and you will be very impressed.
