The oil is not purple and the only reason I will continual to use it is because the shifting is better and does not seem to change with high miles.
I bought a new Ford van in 1977 and used Mobil 1 for he next 300,000 miles, pulled the head, just thought it was time to take a look, it was a 300ci 6
cylinder, the Mechanic's shop where it was at thought synthetic oil was a sales gimmick 1984, until he saw the cylinder walls, had no real wear , His
real job was quality control , dyno testing big block Chevy motors at the Tonawanda engine plant where they were made , he became a believer ...
Down on your knees brothers and sisters
Anyhow it use to be a synthetic oil HAD to be truly a synthetic oil but that law was changed to just meeting certain requirements to be called
Synthetic
Oils in general are a lot better today then when we were kids
Jim when I bought the stores supply it was mostly 20w-50 with some 10w-30 but you have to remember where I live it will NOT get below 70 degrees for
the next seven months
from the Niagara Falls area.
Moral of the story if your shifting seems to be a problem try it.
Speaking of high priced oils , just bought 5 gals of tranny fluid for a Allison transmission HOLY CHIT $50.00 a gal.
