concerns with classic MGs|
Since the introduction of ethanol in
motor fuels in the UK and overseas there have been concerns over the effects of
biofuel on older cars, particularly classic cars. There seem to be three areas
of concern with biofuel and classic cars - corrosion, damage to seals and
when stored for lengthy periods in a classic car laid up for periods during the
winter months, attract water leading to corrosion in classic car fuel storage
tanks and fuel supply systems. The FBHVC is actively working on these issues and
have commissioned tests of corrosion inhibitors and have plans to encourage the
distribution of an inhibitor for classic car enthusiasts.
concerns over the effects of biofuels on the rubber components and seals
A number of members have experienced difficulties with damage to the rubber components
and seals on classic car fuel systems. The concerns are what damage does biofuels
cause and what replacement parts are recommended by key suppliers like Burlen
and other aftermarket spares suppliers for SU fuel systems and where can they
Petrol currently available
at petrol pumps in the UK contains a different mix of hydrocarbons to the mix
in fuel available in the 1970s when the MGBGTV8 with its SU carburrettors was
manufactured. The concerns are current fuels are now designed to suit modern fuel
injected engines and may cause some tuning issues for carburettored engines and
other combustion issues. As these issues affect a range of classic cars we await
clarification from fellow Club members with technical knowledge of the complex
combustion issues and the views of the FBHVC.
