The post was not aimed at you Howie......One of these days the junior engineers might actually visit a library and read up on subjects...but then they would have to leave their cozy dorms, apartments or the party.

lower viscosity.....lower drag, less hp to turn the pump.....ding.....True

Better cooling....increased speed is not an indicator of better cooling...moving faster it just doesn't pick up as much heat from a surface....there is an optimum "rate of flow" for aided cooling.....Ding.....not true.

How much oil pressure?....Chevrolet engineers measured the oil pressure at the interface of the babbit material and crankshaft so many moons ago...afair, the pressure was 5000+ psi. I've seen guys run with 10 psig and 10W oil (straight grade). We targeted 55 psig @ 5500 in our race cars. We ran straight 50W dino oil (valvoline racing (IMG:http://www.914world.com/bbs2/html/emoticons/av-943.gif) oil). This was a "wet sump" system. Oil temps 220 - 230.

Street car...I would be comfortable with a constant 30 psig running above 2000 rpm


I overfill my street car up to 1/2 quart if I'm gonna be slogging a race course or parking lot (or country road without cops). I don't care if I get a little cylinder charge contamination from overfilling...I don't want to see the light in a hard corner. We over filled the race cars 1 quart from stock (we had crank scrappers, windage trays and puke cans too!)

The above is my opinion and observations only....

PS...my favorite oil was Castrol R.....stickier that shit, had a nice smell when it burned...was a great aid to constipation.
