Jeff,
Just remember ethanol and natural rubber don't mix. The ethanol will
cause the natural rubber to swell and deteriorate at an alarming speed.
If it was me I would try and find Premium Unleaded with out the ethanol
and use a good quality ocatane booster and Marvel Mystery Oil. You will
be much happier with the results.
But as always this JMO
