So today I took my 2006 5.9L megacab in to get the oil changed. I had my suspicions about it burning oil. Well there wasn't any on the dip stick. No visual leaks or anything. The dealership asked if i had a chip because it is smoking like I have one. I assuming that's where the oil is going. Does anyone have any idea what it could be. I am also in Midland Texas anyone have a good diesel mechanic out here I hate dealerships. Thanks

How many miles? Is it modded? How bad abused? Have you every heard that dipstick is for measuring oil level in service. Every fillup should include check oil shortly.

It should have blowby if its blowing smoke and losing oil like that. Pull the oil fill with it running and see if air is escaping. Would also be blowing smoke from the crankcase overflow as well.

No. Doesn't miss a beat. Even the dealership said its been awhile since they seen a truck engine as clean as mine being how old it is. They said it ran great. One mechanic said something about The rings. To track my mileage and to see how much it actually is burning. But 4k miles between oil changes it should drop so much that I can't see it on the dip stick.

Normally this is a good idea and highly recommended for every vehicle; however this does not work too well on our cummins. It will let you know that there is still oil in the engine when you check it while filling up but not much more and it will always show low. To get an accurate reading the truck needs to be turned off and set at least 20min, preferably overnight to get an accurate reading. Are you checking the oil after you just shut it off or first thing in the morning? You should also have an excessive amount of blowby if your burning that much oil.

If it has alot of blow by bring it for a compression test. Probably looking at bad rings.

I'm in the same boat as you. Burning alot of oil but not alot of blowby. If would stop breaking on it I'd take it in for a compression test, but just put several thousand dollars into the transmission. Again.

Ever had the The crank case filter changed? If the filter is plugged/dirty It can create blow by pretty bad.
