I can vouch for tesco 99, used it after that evo article and the mid range torque is fantastic!!! At 90.9p on my journey to work, seems silly not to really.
Not sure about mpg yet, seems to hover around 35 whether pressing on or regular A road traffic. Need a few more tanks to make sure, but I say defo give it a try.
You really need to do a few tanks to be sure of results, but it certainly seems more fun to drive. I felt a bit let down by expensive BP ultimate when I tried it.... what do other people think?
Evo seemed to expel the myth of poor petrol at supermarkets, as previously mentioned, fresh petrol is the key, and supermarkets are always busy ( although not sure how popular 99 will be yet....
Anyone else got any thoughts on Tesco 99?
