oil consumption

["Otis Davidson" <otisdavidson@xxxxxxxxxxx>]

Hello Mark,(and List)

I have always run all of my Chrysler Big Blocks(and other engines) a 1/2 qt 
or so low...but I never go below 1 qt low.

I think the reasoning behind WHY engines don't like to stay at the 'FULL' 
mark is because of crankcase windage. If the oil pan is full,oil sloshing 
around catches the crankshaft counterweights more often and gets thrown 
around creating more oil vapor coming out of the breather. It puts x-tra 
stress on the seals which are trying to contain the oil too.

Not only will there be increased windage,but the engine will not make as 
much power if the cranks counterweights are slinging thru the oil when it is 
at the FULL mark,either. Imagine yourself standing in the shallow end of a 
swimming-pool. Take your arm and,in a circular motion,rotate your arm from 
above your head...thru the water and then up again. Notice how hard it is to 
move your arm once it is under water??? The same principle applies to the 
crankweights spinning thru the oil.

There are windage trays available from jegs.com that cut down on sloshing 
and windage....but I'm too lazy to install one.

noticing...hehehe.

hi all:

years ago friends of mine would tell me to run my mopar V-8's a qt. low as 
the first qt. would burn off after 5-750 miles and then stay at 1 qt.low for 
the next 1000 miles..I must admit getting the same results myself..any truth 
or reason to this? my '74 imp 440 is doing the same thing...thanks!
