Heard this interesting theory from a local guy the other day. He never changes the oil in his Diesel Pusher BECAUSE he has to add a quart of oil every 1,000 miles. His theory is the oil is already changed every 20,000 miles from adding a new quart every 1,000 miles. He does change to filter every year or 10,000 miles which ever comes first. Since oil does not wear out and it is the additives that does and the filter is cleaning the oil, he does not change it. Thus far he has over 150,000 miles on his rig without problems. I did go on a couple of trucker forums to see when they changed their oil and the norm was 50,000 miles or more but they did change the filter more ofter. What ya think? I have an oil change coming up, LOL!

I think I'd follow the manufacturer's recommendation and not play games with a very expensive engine.

If you want to extend your change interval, at least send a sample to one of the analysis labs to be tested.

Problem is he never gets the contaminates out of the oil. There are plenty of acids and other contaminates and even grit that never gets out of the oil. But then again if he keeps it up he may get to put in two quarts every 1000 and change the oil faster. I don't think you'll ever find a trucker who doesn't change the oil. Here's a truth, oil is and always has been cheaper than machinery.

In theory it sounds simple but have to agree even with more frequent oil changes, it seems one would not be correcting the oil content and getting out all of the engine wearing grit.

Having the oil tested to find out how well this method is doing is an excellent idea, one I'd promote should someone want to try this plan.

And I'd do more indepth research. On a rig that is still under warranty...could be the manufacturer's warranty could be voided.

One thing I find curious...if he has had to add one quart per 1000 miles since the engine was new...is there indeed an issue he should be addressing to reduce oil loss? We've not had to do that with our DP.

My old 72 Ford Pinto consumed over a qt of oil every thousand miles when it was new. I never changed oil. I just added. The engine quit at about 125,000 and I had it towed and rebuilt. Mechanic called and said he never saw anything like it. There was almost 3" of sludge in the bottom of my oil pan. When they drained the oil they only got out a couple of qts although dip stick said full.

Since then I change oil and filter often. Probably more than required. Oil is cheap compared to break downs and where the happen.

I think this should answer the OP's question. [emoticon]

A lot of 70's small engines crapped out at 100,000, that was near their life. Still 3" of sludge teaches me we ought to change oil.

Today's motor oil is only about 10-15% base oil and 85-90% additive package, which breaks down over time.. What makes it a multi-vis oil is an additive that expands when heated and under a microscope looks like long strands of spaghetti.. As the oil gets constantly circulated thru the oil pump the pump shears these strands and as they become shorter, your oil viscosity drops.. If you use 15-40 It is 15 weight oil with this additive.. as it wears the larger number drops... The other reason to change oil is to remove contaminants, such as acids, water, rust, and unburnt fuel..
