Hi,
Thank you for letting me share my car problem with you, hopefully someone will help solve the problem. I have a 1999 Dodge Ram 1500 full size truck with a crew cab, automatic and a 5.2 L engine. The truck had 60,000 miles on it when I purchased it three years ago and now has 75,000 miles.
The truck runs very well and has plenty of power, although it does not get very good gas mileage. The problem I have, which I discovered about six months after I bought the truck is that it uses a lot of oil. I’ve never kept real good track of how much it uses, but I would guess I go through at least a quart of oil every 1000 miles. I do not hear any unusual noises in the engine. I do not see white smoke coming out of the tail pipe, although my white truck may show a little black film around where the tail pipe ends. The oil on my dip stick is very black but has no white residue.
I told my mechanic about the problem and he said he would put some kind of a gauge on the engine and check the engines compression. He said the engine checked out ok and he doesn’t know why I would be using so much oil. I know there has to be an explanation for this and I’m hoping someone on this forum can shed some light on it. Thanks again for the help.
Jon M.

Hi
All I have to offer is this...
Worked at GM dealers and had similar complaints...
According to GM engineering, it is normal for a GM engine to use a quart to a quart and a half of oil in 800 -1000 miles...
I know this sounds excessive..used to be use to using a quart in the 3000 miles between changes..
But if all checks out ok,not much you can do..
Check with Chrysler/Dodge and see what they say..I'm sure they have something similar..
They(GM) would recommend doing an oil comsumption test...
We were to inspect for any leaks,etc...check pcv system operation,..etc..
Then change the engine oil and oil filter, at customers expense, then have the customer drive the vehicle and keep a check on the oil level, (we would check if they stopped in,).then when it was a quart low,document the mileage ...if within the specs as stated above...then there is no problem found ...
Now Cadillac,Northstar engines were great for consumption,leaks...some had to have whats known as a 2 stage decarbon process done ...corrected most of them,but some had to be repaired internally....
Thats all I got
See what the others say

There is a metal plate on the bottom of the intake. This has a gasket on it. These gaskets blow out and allow the vacuum from the throttle body to suck oil into the intake and through the cylinders. It burns the oil, but it is so slight you can not see the smoke. Plug off the PCV and remove the hose from other valve cover. Place latex glove or balloon over the hose. If the glove or baloon swells up, gasket is blown and needs replaced. Good luck.
Being way2old is why I need help from younger minds
