What is considered "normal" oil consumption for a CUT diesel?

[spruce Deere]

My 790 at 500 hours now burns no oil. If it does, its so miniscule I cant notice.

It did use some oil during the first 150 hours or so. Bout' half a quart then it quit that.

Run a 648 g-II log skidder when I not farming. On the reman 6.8L deere engine with 7000 hrs that powers it in 200-250 hours of operation burning around 1200 gallons of fuel, it MIGHT use a half quart.

My 94' gmc has 248,000 miles on it and somewhere around the 200k mark it started using about a quart within the 3,000 mile change intervals.

So, I guess a little oil burned is o.k. I like it when engines are not oil thirsty better when they are. Some burn, some do not.

Thank you for that information...I burn thru about 75 gallons of diesel per year so 1/3 of a quart between 100 hour change intervals appears to be quite reasonable. What made me start this thread is I remembered when I was truck shopping back about 1978, I had a GM product that I thought used too much oil, and the dealership that sold me the car told me it that it was not considered excessive oil consumption to have to add one quart per 1,000 miles.

I have never had to add a drop of oil to either of my tractors, a Ford 861 and a Jinma 284. The Ford is 50 years old and has 2,000 hours. The Jinma is 9 years old and 925 hours.

I have owned over 25 different vehicles and the only 2 were I had to add oil were both GM's. I have owned 4 GM's and 50% of them needed oil between changes. One, just a qt every 3,000 miles. The other used a qt every 600 miles.:confused2: GM said it was within tolerances.

I have owned Toyota, Ford, Honda, Nissan, Dodge, BMW, ect and never a drop of oil added.

Closing in on 50 hours on my Bobcat CT230 and oil level hasn't budged.

My old Yanmar 1700 did not use any oil between changes that occurred once a year...
Approximately every 60 hours or so...
Traded it in at 1250 hours...
My NH 1720 does not use any oil either between yearly changes...
Around 75 hours per year and currently at 580 total hours...
As a reference to other engines, my Buick 3800 V6 uses a quart every change...
I use the GM oil minder that usually calculates changes at 7500 mile intervals...
She has 160K miles on her now so that engine is performing very well...
My 2003 7.3 Powerstroke usually goes down 1/2 quart between changes @ 5K miles...
She has 100K on it...
I've got 3 good vehicles with reliable engines...

I think if you ran older stuff or pushed the change intervals you would. My saturn and Ranger both suck a qt about every 600-1000 miles depending upon speed. The toyota used about a 1/2-1 qt when i went to 9K mile oil chage on syn, i did not like the consumption or the length so i am back to 6k oil changes.

I do 7500 mile changes on my Ford PowerStroke, 5000 mile changes on my Nissan Titan, and 12,000 mile changes on my BMW 335I. I could go more on the trucks, like 10000 on the Ford and 7500 on the Nissan but they both are worked hard so they get changed via the severe duty schedule.

Tractors each get it every 100 hours or in the case of the old Ford, once a year.

Both my GM's that used oil got the standard 3000 mile changes and started using oil while still in warranty before 30000 miles.

I'm down about a 1/2 quart (or less) when I change oil on my two VW Diesels at 15k mile intervals.

Sigh....An another unadulterated GM hit piece...I have never experienced anything you've said in 20 years of GM ownership and with trucks with 200K on the clock. Lighten up on the GM attacks..It washes out the infomative things that you have to say.

Engines have certainly gained respectability since the 60-70s. I never had any tractor back then that wouldnt use 1-2 quarts per 12+ hour day every day and we ran IH, MM, AC and Ford and they all would use that much oil which was considered normal oil consumption back then for any diesel or even gasoline though the gasoline engines werent usually as bad as the diesels.
I now have a 1980's model Yanmar and it uses no oil between change. I just did the 50 hour service on my LS and the oil wasnt even black like I remember all diesel engines. It was cleaner than my pickup truck at 7000 mile oil change. The engine manufacturers have really tightened up the tolerances in the last 40-50 years, although if you try to return a vehicle for oil consumption, they will try to BS you into saying that 1-2 quarts every 1000 miles is acceptable (in some cases that I have heard about that is)

I worked for a farmer when in high school that never changed the oil in his IH 806's just the filters occassionally. His thought was that by adding 2 quarts per day, he was changing the oil about once a week anyway and the filter was pulling out any thing needing to come out. As far as I know, his engines held up as good as any of the rest of his brothers who farmed with him as partners and they changed oil at regular intervals. Of course with the 806's you had to check the oil while it was hot at quitting time because in the mornings it was about like hot tar in consistency. It always amazes me how some folks can abuse the heck out of equipment and never have it break down, while others baby them and clean and polish and everything goes to heck on them.
