Hey Scotty, I tried 100 octane fuel in my 93 Celica (probably like 95-96 octane in US) which claims 7% more power and up to 5% more torque. On their website, they also say that it has better additives and cleaners. Those horsepower and torque njmbers they say is from a Golf V 1.6 FSI. I was thinking that this car is newer it would better adapt and compensate to premium fuel than my Celica would. But at least it will clean my fuel system a bit. Not planning on using it everytime, but maybe once every 3 months. It seems to have a little bit more torque but could be placebo effect. What do you think? Thanks
