When I went to Autosport Intl at the NEC there was numerous stands advertising BP ultimate. Now I ignored all of them except one when I heard the familiar sound of a dyno. I went in to investigate.
What stood before me was a v8 4.2L Audi A8 looking gorgeous as ever. Now they were trying to prove that there fuel is best for the engine and performance. I quickly took no notice whatso ever of the dyno with 2 Saabs one with ordinary petrol one with BP ultimate with the BP one running 40BHP up on the other one. But what intersted me was the Audi A8. They had converted the car so the left bank ran Ordinary fuel where the right bank was running BP ultimate. With a video linked boroscope they showed the exhaust valves above the piston. The left side obviously looking like crap but the other side looking very much cleaner. I even made sure I knocked the boroscope to make sure it was live and sure enough it was.
Now with this in mind I thought yeah right but I must say from reading the sales speile on the Tinterweb I'm thinking of running this through mine every now and again. Now is it a case of running 97 ron petrol will increase the cleaning effect because of the burning is better?
Have a look at this website link. Especially have a look at the videos of the Audi running with the boroscopes inserted.
Opinions and views on this. Is it worth it every now and again or is it worth it every time or is it just a waste of time?
