Every maker specifically advises against using anything BUT SAE 30 over 40 degrees.

At the begining of this rudolphna states "I have three bottles of Pennzoil YB 10W-40 left over from my grandfather."

Then Bror Jace states " 10W-40 got a bad rap years ago when multi-vis oils were new and the polymers they used at the time were a real mess ... would sludge up a car in no time. "

If the oil in question is oil left over from his grandfather then it is just posable that this is some of the early oil that had problems.

No no it's new oil. He sold me the car and gave the the oil (which had been on his shelf for about 3 months) along with a Gallon of Dex-cool, and a can of 134a
