right? I know which "racer" he meant.
I never put any of those crap in either of my cars, but having seen the snake oil advertisements, I don't have any doubt that they are just that -- just snake oil to take advantage of placebo effect.
If you told me a modern car was knocking due to bad fuel, I'd have believed you, but comparing the fuel quality on a 3 wheeler is pure worthless. Any car worth its salt should be able to adjust its compression ratios, and even if it does not, putting a 95 RON doesn't do anything to improve fuel economy if the car is rated for 92.
That said, this very topic is one of the internet's most argued topic, and I'm not wasting any more time about it. I respectfully ask you to stick to your opinions, but be considerate when you diminish someone else's opinion unless you have proper evidence to strongly counter-argue. Make a primary school test. Do a blind test - ask a friend to mix or not mix your snake oil without telling you, and see if you can tell the difference.
