Percolation? Heat soak? Don't drive during summer??

Yes he does run what ever Walmart flavor he likes at the time. Same with transmission fluid too I think.

I think when I first got the car and did a tune up on it (wires, plugs, oil change,coolant flush with new cooling parts minus radiator) i read here that the vr1 was good and already had a high zinc content in it. I went with that because it eliminated the potential of me adding to much zinc or to little zinc to an oil that didn't have any or the right amount in it. Many of you guys have been doing this for many years so to you most of this is second nature and you've come across many of the common and not so common problems. This is my first old car, and first time I've really really torn into a car to rebuild different systems so I'm trying to not make the dumb mistakes... like not adding extra zinc to the wrong oil. Ill just remember to next time I change the oil, to add a lower viscosity oil, which may be sooner rather than later because my oil drain plug leaks and I want one of those fancy deep oil pans. Tony actually showed me the one he likes and offered me one when we did the cam but I always like to not take things from people and felt that I could buy later on. :)

You made a great call. Chemical experimentation is best left to the experts, LOL. As others have said, some places will order you the same vr1 in other weights.
Lots of us have run 20w50 with no problems. Is it optimal? Impossible to say without tons of investment in testing, but there is data to suggest a 10w40 or 5w30 has some benefits if it has the high pressure additives we need (zinc, zddp).
