The only time I drive a diesel is for work. Had the truck serviced and a synthetic oil was used. Then I notice on the sticker that the interval is 3000 miles. Shouldn't the synthetic extend that just like in a gas rig? Sounds like they just want another 200 dollar oil change as fast as they can get it. mtmuley

My '08 Dodge diesel has a 7500 mile interval with dino. A lot of shops automatically put those stickers in the windows just to drum up business. Car owners think they need it changed every 3k but the car makers know they don't. Go by the owners manual, not the shop's profit and loss statement.

Local guy I know was running a Dodge Cummins, in about a 98 or 99 Model 3/4 ton 4WD...he was running Mobil Delvac 5 W 40 in his... and was changing it once every 20K on it, and changing the filter every 5 k....
was a work truck used in commercial application...must have worked fine, as he sold it to a happy buyer with 400K on it..and still running strong...and no consumption issues..

I specifically tell them the mileage I want put on the sticker (if I have it done).

Thanks guys. Delvac is in this one. Miles are to and from an out of state jobsite so mostly hiway. Figured it had to extend the change interval. mtmuley

Important to check synthetic oil level and top it off if necessary between 7,500 mi. changes....

Do an oil analysis at 7,500 and see how the oil is doing. Not the cheap bench top, either, use a real lab. It's not that expensive, and it's the only way to KNOW, instead of guess.

Shouldn't the synthetic extend that just like in a gas rig? Sounds like they just want another 200 dollar oil change as fast as they can get it. mtmuley I wouldn't worry about it. Probably just made a mistake, a different person from who changed it and thinking dino oil when he did the sticker. On a diesel, with dino oil there's nothing wrong with 3000 mile changes. Oil gets black real quick in a diesel and costs nothing compared to an engine. In mine it also lubes/cools 3 expensive turbos. I don't mind changing oil every 3-4000 miles, it's cheap insurance.

Tx270, you may be right, but I agree it's cheap insurance. I bought my 2001 Expedition new and change the oil every 3000 miles and it just turned 260,000 miles.

Your vehicle so maintain it how you wish, but changing @ 3K miles in a gas engine is excessive, IMO. my gas motor's oil barely has color at 3K.
Because of the soot in a diesel makes a little more sense, but that much to me.
Just go by the owner's manual.

I don't mind changing oil every 3-4000 miles, it's cheap insurance. Like heck it is! The difference between a 3,000 mile interval and a 5,000 mile interval (which are both EXCESSIVE for a diesel) amounts to 40 additional oil changes at 300,000 miles, or about $8,000. Push it to 7,500 miles, and you are over $12,000. I'll spend $80 for an oil analysis a couple of times to save $12,000.

What kind of pixie dust are you guys adding to make an oil change $200?

I should also add that the 7500 mile interval in my Dodge Cummins was the SEVERE service interval by the owner's manual, which is what I change all my fluids under. If you went by the "NORMAL" service interval it was 15,000 miles.... I sold that truck to a friend about 18 months ago. It had 200,000 miles on it then. Not sure how many it has now but I know he's never touched the motor except to change filters and the oil every 7500 miles.
