Maybe the batch of oil would last longer, but you also spent more on oil. Even if it didn't cause any issues, it would probably be a wash (cost-wise) at best.

I've seen this discussed before..

The theory is, more oil means it has more to stick to parts and help cold starts, and that it stays cooler. Sounds good initially, but.....

I'm not engineer, physicist, or any other type of scientist, but intial thought was comparing it to a pot of boiling water. In very little time, it all gets to the same temperature. Starting with more water just caused it to boil over quicker due to lack of room. This thought, when applied to a sealed system in my mind, led to bad results.

I never bought into it myself. Like other have said, GM has scientists who know this stuff, so the marks must be there for a reason.

You can only go so far up the oil pan with oil before you get to a point that you start turning the oil into air riddled Froth... At that point you could loose oil pressure as the oil pump is trying to pump air bubbles resulting in engine damage.... This is the reason that you want to avoid overfilling.. I fill my cars with 5 quarts with an oil filter change... I am always a hair above the top of the cross hatch... Never go any further than that...

I too use a bit of oil.. I may add 1/3 of a quart for the trip I will make to CT then over to WV and back to FL... And the only real reason I add is due to the fact that I can't stand to see the level below the top of the cross hatch...

Put in an oil cooler if your concerned about it. That will cool the oil and give you ~2 qtus extra capacity

If you're so hellbent on running more oil another easy way is to get a K&N gold oil filter which increases your capacity by 1/2 quart bringing you to an even 5 qts. I like it because then i can just pour in the whole 5qt jug of Mobile 1.

The K&N Performance Gold HP-1001, as far as I know, doesn't increase the capacity since it'* the "OEM" size from K&N. Which model are you referring to specifically?

The one offered through Intense claims to increase capacity by 1/2 Qt. I ran one with 5qts and was right on the full line of the dipstick.

Wow, good to know, thanks. I'll probably order a few with my next Intese order. You can't find them that cheap in the stores either.

I'm honestly glad someone posted someone posted this..

I am installing a turbo on my car in the upcoming weeks, and actually made me think of asking how much oil I should run. I'm guessing 6qts
