How much oil do you use?

My '92 ECSB doesn't use any. But my '07 Tahoe with 60k on the clock uses a quart about every 1500 miles, and GM says its normal!!!

When I was at the parts store buying a gallon of oil so that I had plenty to keep it topped off I mentioned that I was starting to lose(burn) oil and the guy there told me the same thing. Apparently with the new GM engines it's normal to use a quart between oil changes. Sure seems odd to me.

A lot of these LS motor's have pcv and crankcase breather issues and they vaporize oil in the intake manifold, I fixed mine by puting small breather filter's on each valve cover. Now I don't loose the oil and my intake is still clean inside.

Now to affix the egr plug!!! or have you already done that?

Just a small bit of info, but the PCV system works in 2 different ways: The gas PCV is designed to keep residual gas fumes from collecting in your oil(gas breaks down oil). The diesel PCV is designed to cause a vacuum in your crankcase to stop oil seepage thru the gaskets. Diesel doesn't break down oil, unlike gasoline.

Yeah I already have it done, I have another 02 burb with a 5.3 that I am going to do next.

Oh good deal man!!! Ya got SUBs in that bURBAN?

 

[DRAGGIN95]

No it is our work burb, loaded down with tool's.

Is it the GenIII Ls motors or the GenIV or both? I've only heard about it on newer trucks/burbs. I haven't ever noticed my mom's 03 burb using much oil.

 

[DRAGGIN95]

Any gen 3 can do it.

212k on the clock of my 95 I keep the oil changed every 5k with synthetic 5w-30. I do not lose but maybe a 1/2 quart between changes .

what are you guys running for oil, i've got a rebuilt 350 and i run 10W-40 to keep the lifters quiet(er), i've kinda always been wondering if its too thick though.
