Hey Jason....I've got 8 liters of 5-40 Cosworth setting in the shop now....gonna run it against Royal Purple Racing 41 and see what kind of UOA this stuff gives me.....I was out in California visiting the Cosworth facilities....I did spill my "Coca Cola" in the big vat doohickey....Oops...
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
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...
Maybe some of the Cosworth folks kept some Jack Daniels in oil bottles so they could pour themselves some on a slow afternoon at work, and their boss wouldn't notice since all he sees are oil bottles lying around. Then one day a new guy didn't know what was in them and packed them up to be shipped out.
Pity the first hardworking Cosworther to discover he was drowning his sorrows in a tall glass of 5W40.
