im still touching 145 indicated on the track, guess its like adding and extra bit of HP you dont really notice it, my can is supposed to give me a 3 - 5 HP gain.. i cant see how lol, id still rather clean injectors over 1-2% hp loss

I've seen 145 with a tailbag on. It's easy if you've got an open can- it helps push the power up the top end where you need it for that kind of "speed".

Don't confuse the "octane boosters" and the like with "injector/carb cleaners".

The cleaners do work, they are usually fairly simple formulations, but can help remove build-up uf fuel deposits. Use them as recommended on the bottle, more does not equal better.

Premium fuels can have benefits other than just performance or economy. Depending on the engine, you can feel better response or smoother running, but this is very engine specific. Some engines are much more fuel sensitive than others (as are the owners).

If you don't see any benefit from using premium fuel then don't use it. If you notice a benefit, then fine. I use it in some things but not others.

For info, Shell V-power is guraranteed 99RON minimum.
