99 premium petrol
6 Answers
Ive always filled my car with normal 4 star and ir runs fine, but I filled it recently with premium as it was all they had, and I was surprised to notice small but marked improvement in performance. Engine is 2.5 injection. Question is, if I keep on using this petrol will it cause damage to the engine, after it having done the past 65K miles on 4 star 95oct?

I have a Vitesse with the 2 litre carb'd version, designed for 5 star and it certainly runs better with higher octane fuels, as I can run it close to Triumphs ignition advance settings rather than the massively retarded settings I have to use with an unleaded/booster mix.

Hi Carol,
Funny you should say this as I always ued to fill up with Morrisons standard unleaded but since the petrol incident I have been avoiding it. I went to Esso and they only had the premium 98 octane pumps working so I begrudgingly filled up with that but noticed I was getting about an extra 2 mpg from it so will have to work out wether its worth the extra.
