Re: Best UK Unleaded Fuel? (Is there such a thing!!?)
Used Supermarket (Tesco RON 95) stuff for a few months in the Primera, and it was crap. I was getting overruns all the time, and couldn't figure out why.
Thought the TPS was faulty or the Throttle Body had a leak. After replacing both (costly), it turns out it was the fuel, only discovered when I moved, and the closest garage was a Total. In short, never again. I'll pay the extra £2 every time I fill up, just to know the fuel is of good quality.
Put it this way : Even though Asda 10/40 oil has the same basic ingredients as Castrol 10/40, which would you put in your engine?
