V6ers! CHECK YOUR OIL! Step inside...

The Mercedes Kompressor 4 cylinders are horrendous as you can pour oil out of the intake baffles (We dissasemble the SC unit and machine the snout housing down so a smaller pulley can be installed), and look at the Ford mod motors.

Very few GenIII & IV's will not ingest oil into the intake air charge (any catchcan, even a beer can w/two fittings in it will catch a good deal of this oil).

Allthough I have yet to build one of the new V6's, just adding the CAI's and such has shown staurated air boxes (the intake snout slopes down so in runs back into the air bridge at rest) even with only a few thousand miles on them.

The real issue IMHO is that the manufacturers seem to feel the majority of car owners are just that, owners, not enthusiasts as we are and they will never complain as they are just a bunch of sheep that drive to work/shopping/etc. and don't ever get so close & in tune to their cars like we do so they take all that into the R&D & cost to impliment a good solution.

The sad thing is the V6 owners that don't monitor the consumption issues are going to have spun bearings, etc.

The very fact that GM knows that most people are not car nuts that are going to check their oil all the time still leads me to believe that they have a very poor design on their hands. This motor is also sold in suv's that soccer moms run, and I can tell you they're not checking their oil at every fill up. They either go every 3,000 miles or wait until the oil light tells them to. From what your saying this will be too late for a lot of people.

Thanks for your input. It makes me want to trade my new traverse for something else. I don't want to wait for them to get it right.

Thanks for the heads up..... I will keep a close eye on consumption.. we had a dodge neon that would eat a quart every 3000 miles and they said that was normal.

Not exactly the same motor as this version of the 6 used on many GM cars puts out the most horsepower. In a way this is almost an entirely new motor so now we are seeing problems never yet seen on the older ones because they aren't exactly the same motor.

I just checked mine this morning before leaving for work. Dip-stick indicates FULL.

FYI:
I have 11,600 miles on my Camaro. I changed the oil at 600 miles and switched to Mobil 1 Synthetic, changed it again at 6,600 miles. I plan another oil change with-in the next 1,000 miles. Computer tells me I am at 50 % oil life.

If your oil level is okay after around 10,000 miles then you are probably okay. Most of the motors should not throw bearings but there are definitely enough doing so to warrant a quick check just to make sure yours doesn't become one of them.

I've got about 24,000 miles on mine and mine doesn't seem to burn any oil. I wait for my oil life monitor to tell me to change the oil too... last time was about 10,000 miles between changes.

people think since they have 300 hp v6 that they can take those older Z-28's with the 300 hp v8. next thing you know blown motor. lol.

Oil level fine here. I've checked frequently during the last 15k and 3 oil changes (mobil1)

i have the v-8 with synthetic oil and have never waited to see the computer say to change the oil. i usually change it when it goes around 40%. how far you other guys waitin on oil changes?

[67 GTO]

I've never gone below 40%

[justmeron]

That's alarming! Hope it is not a trend.

QUOTE:
If what your saying is right then everybody should be having the same problem. They all have to follow the same EPA standards. So it can only go two ways as far as I'm concerned. Either a design flaw which you say is incorrect or everyone's motors will do the same thing under the current EPA Rules. I guess the LS3 and the L99 will eat oil also since they are under the same guidelines. Sorry but using the EPA is a cope out to me.

REPLY:
the pcv passes more oil when at WOT than at any time. a lot more. its possible that two cars could the be same and only one run low of oil because the other car sees little if any wide open throttle.
just check your oil often and add a catch can if you are going to run it hard. also another reason to change your oil more often than that calculator tells you to.

37xx miles, oil changed ~2000 w/ Penzoil Synthetic..still full(knock on wood).

I don't plan to go below 40% either. This keeps it around 6000 miles for me.
