The Porsche Club of America 's tech
session held on March 19 at Extreme Motorsports was well attended --by
Porsche owners. There were about fifty of the rear engine philiacs and
one "I roll"er with a leaky freeze plug, something those 911
guys don't have to worry about. The guest speaker, Ralph Compton of BG
Industries, was an expert on fuels and oils that, at the conclusion of
an hour and a half spiel, pushed his company's valve and combustion
chamber cleaners. Obviously, he had more knowledge about modern gasoline
- he prefers to call it "gasoline based fuel"- than you could
shake a Porsche rear end at. The history of modern auto fuel started
after the oil crises in 1973, when the oil companies began extracting
80% , instead of 20%, of "gasoline" from each barrel of oil.
Not only did they have to add "empty calories" to make up the
volume, but they also took out all the natural volatile solvents, such
as naphtha, toluene and benzene. This is partly beneficial, as far as
air pollution is concerned, but it detracts from the fuel mileage and
leaves more deposits in YOUR engine, principally on the valves. Unless
you are willing to spend the better part of $100 on Extreme running
B.G.'s products through your engine, he recommends using Chevron gas,
with a bottle of Techrolene(?) additive in every three or four tanks
full. Or you can buy an II oz. can of B.G.'s 44K gas treatment for $12
apiece (retails for $15 to $18) if bought in quantity, that you add to
your tank about once a year. Maybe it's something for our club to
consider. |
