Well FireDan50 is a very responsible guy. He understands what he has and the Q16 is just for some fun and maybe a pass down the 1/4mi.

Cool for bragging rights on the forums, but kinda useless @ $16+ a gallon and more likely to destroy your expensive sensors.

They have a few oxygenated unleaded fuels that would have been cool to see, though. Maybe you can try those next time?

We were going to use the MS109 fuel, which we have used TONS of in the past, but opted for the more potent Q16 which has never let us down. It is leaded, but its not going to destroy sensors in a single dyno session. Used sparingly he should have no issues for some time to come.

As for your question/comment regarding the fuel, you can safely run leaner due to the detonation resistance you are correct. It does require roughly %5-%10 more fuel over a basic pump gas when it comes down to picking the right injector for your build if you intend on using an oxygenated race gas. Compare it to the way you can run leaner AFR on E85 thanks to it burning cooler and being more detonation resistant, but it demands 30% more fuel than pump gas. Also be mindful of brand as certain injectors do not like the MTBE oxygenated fuels.

Thanks,
