The guy is right about using TCW3 oil but he's way off the mark on gasoline, in the 1970s to mid 80s we found clogged fuel filters often way before the specified 12,000 mile interval, today most gasoline engines never need a fuel filter. When fuel injection became popular they had to improve the fuel quality.
He must work for or have stock in Pennzoil.
all of today's fuel injector vehicles have a fuel filter, certain models have two.
how was he off the mark about gasoline? if u read his posts and testing they just happen to be using pennzoil. any TC-W3 meeting the spec are the same, except for price.
