For those Brits still despairing the loss of 4 star, well here's where you can get some.
The EU "Lifestyle Controllers" have condesended to allow minimal sales of 4 star fuel to special interest groups. This actually amounts to some 100million litres pa. I believe some of the major oil companies have retained their 4 star pumps at a few select stations but one company sells it at all of their outlets, they apparently have 82% of the market. The company concerned is Bayford Thrust, they maintain a web site with a list of filling stations which seem to be fairly well spread through the country, now I'm not going to put the web address because one of you adjudicator types might slap my wrist but they are a UK CO mpany and thier name is bayfordthrust, that make sense
Hope this is usefull - no need to worry about which additive to use now.
