This is not specifically a classic car issue, although we all want to
preserve our ancient engines as long as possible. Most Saturdays I read
Honest John's column in the Telegraph, and he's always banging on about
how
supermarket petrol doesn't have any detergents in in it, causing all sorts
of problems, whereas Shell and Texaco fuels are the ones of choice. He
says
it applies to diesel as well - these brands are high lubricity, Tesco etc
is
not. Last week I asked him what independent tests show the superiority
these
brands. Guess what? He couldn't cite any, but said it was his experience
and
that of his readers.

Twice I have had real trouble with Sainsbury's fuel causing pinking and
rough running -- never had any trouble with fuel bought from Safeway.

Real worry is the rate at which petrol stations are closing -- the housing
boom hasn't helped as land prices soar selling for redevelopment becomes
more tempting. In my area lack of petrol,station outside the supermarket
chains is a very real problem, even very busy stations are closing leaving
whole tracks of greater Glasgow without a petrol station.
