Of the automotive additive products out there Lucas probably makes some of
the best in that they do what they claim. The oil stabilizer is basically a
viscosity improver with some other benefits. If it is really beneficial can
become another matter. My own thoughts are that if the engine is healthy and
the correct products are used additives should not be needed. If you are
still holding 40 psi on an engine of that mileage then things are good and
the past practices have worked. While increased oil pressure appears to be a
good thing this also brings increased horsepower loss in the way of oil pump
losses and increased drag in the engine. In the extreme these increased
losses can also mean higher oil temperatures.

Subject: Lucas Heavy Duty Stablizer

Hello Volks-

For the last year I have been running my stock 2.1,  which has over 200,000
miles on it,  with four quarts of Castrol 20w-50 and 3/4 of a quart of Lucas
Heavy Duty Oil Stabilizer.  Where I live it never gets below 30 degrees.  I
have noticed better oil pressure on my gauge-  60 to 40 range, instead of 40
to 20 range and no lifter noises.  Anyone else have experience using this
mix or an opinion that this is not a good thing to do.
