yes, supermarket fuel is bad. Optimax is the fuel of choice for the 300, runs nice and is FAST on that stuff, supermarket fuel makes it detonate badly so it never gets given that. Normal fuel also cause a mild knock and results in safety boost, this why optimax makes it so much faster...
Do Tescos sell a lower grade fuel?

I won't use supermarket fuel either. My bike is treated to a drink from BP every day and I get points on my Nectar card then as well. I'll have enough points for something nice in about 5 years

thats because optimax is a different fuel than all the rest sell, all the other types are the same no matter where you buy it. Ive stopped comming on here much now so probably wont reply for ages to this thread but its a complete joke to suggest a car would run differently off fuel from 2 different garages cos its all the same
There are only 2 types of "unique" fuel sold to the public, thats optimax and BP's 98ron effort.
