RE: OIL Viscosity
By Joe Chew - 04/24/2001 3:09:19 PM; IP 131.243.36.188
After break-in, I started running 5W50 Castrol Syntec in my 390-powered Thunderbird. (Mildly built engine, not used terribly hard.) This seems to have made the pressure gauge cease its occasional visits to zero when idling at a stop light just after a freeway run. My subjective impression is that the engine is also a bit quieter.

I found that this oil FAQ answered a lot of questions for me:
http://www.vtr.org/maintain/oil-overview.html

If you're looking for a simple answer to "which is the best," you'll look there in vain, but it does help you decide what criteria to optimize for in your car and your climate and your budget. The one I chose struck me as a good "all things to all people" choice and was readily available and not too terribly costly.

One take on restricting the oil flow into the top end (I have not done this myself nor seen it done) is at
http://www.tbirdranch.com/techtips.html#Surplus of Oil to the Top end

One man's opinions, worth what you paid if your connect time is cheap:
