"The testers placed freshly rebuilt engines in 75 New York taxis and then ran them for nearly two years, with each cab racking up 60,000 miles, placing different brands and weights in different cars and changing the oil at 3,000 miles in half the cars and 6,000 in the other half. At the conclusion of the test period, the engines were torn down, measured and inspected. The conclusions: Regardless of brand of oil or weight, no measurable differences could be observed in engine wear. Furthermore, there was no difference among cars which had oil changed at the shorter or longer interval."
I was not aware Consumer Reports ever tested motor oil; many of you probably already were, but to me this is a strong case for cheap dino in the average vehicle. I know this will help me some knowing this report exists even though it is older; but hey, oil formulations have even gotten better since '96.
I guess the one thing to not would be that the weight did not matter but they were not testing in DOHC 5w20 FF motors, they were Taxis which in '96 would have "probably" been Chevy V8's (which would run on Crisco)
ALSO, I might add that in extreme conditions I might argue (such as sub-zero temps, desert towing), but generally speaking, if Taxis were used as test subjects, that is some pretty good evidence...
And the other though I had is that 60k might not be near enough miles to show anything. Whereas maybe a plain old dino motor would go 200k & a full-syn motor would go 300k?? maybe that is one point to be considered, but I am still happy to see this report. Valvoline obviously thinks it matters more in the long-term since they step-up their guarantee based on the kind of oil you are choosing in their line up.
Wal-Mart SUPER-TECH anyone??? MMMMM LOL
