Jason,
I ran across that stuff the other day by accident when I was googling for motor oil info.
Looks like it may be a contender. Appears to be a synthetic even by the standards of the most devout of the Orthodox Synthetic Faith.
Of course, at $8.49. per quart, if it's not at least as good as Mobil 1, Redline or Amsoil on at least one oil quality criterion, it seems like a questionable value.
Still cheaper than Synlube...
BTW, did you get it at the "liquidcosworth" site, or do they have a reseller?
I notice on their "buy" page they also have:
COSWORTH PERFORMANCE ENGINEERED COOLANT ADDITIVE
and
COSWORTH PERFORMANCE ENGINEERED FUEL TREATMENT
I wonder about that coolant additive. Is it supposed to be another "Water Wetter" ?
Be interesting to have someone test these. Not me. My wife needs the money for shoes...
