Ah forget plus points, you get Nectar points with BP
I have tried the fuel a couple of times and it is definitely more "consistent" than Shells products. The main drawback I had was that it was 10p a litre more than the unleaded
Anyway it was good, I felt the car was much smoother and much less reluctant for the APC to back off the boost. One of the best
I run BP Ultimate all the time now, because the BP garage is my nearest filling station whereas the nearest Shell garage is about 11 miles away. Optimax gives the most noticeable "instant" performance boost, but over time the cars performance seems to improve by using BP Ultimate. This may be due to the cleaning agents in Ultimate "freeing up" the engine to some degree.
I have to say that despite bp ultimate being 97 ron against optimax's 98, my car definitely feels more consistently sprightly on ultimate than optimax. Some optimax is good but other times I could swear they are just putting regular 95 in there and selling it at an inflated price.
