Some oil companies champion the 100,000 mile oil change and even dare to declare that new car warranties remain in effect even if the oil is not changed for 100,000 miles. The trick is to use a synthetic oil, a bypass filter and periodic used oil analysis. So does anyone really practice 100,000 mile oil change intervals and if so what is the reaction of the new car dealer when warranty work is requested?

Topic: Is the 100,000 Mile Oil Change a Reality?
For some people on this board it is.

Just wondering why an oil company would want to produce a 100,000 mile oil in the first place unless they plan on charging $75 a quart.
I'd be interested in which oil companies are "championing" this so call OCI.
I would venture to say that even the very best top of the line (insert your favorite oil here) motor oil, wouldn't last 100K if you jacked a brand new car up on jack stands and let it run 2500rpms for 100K miles.
The claim itself seems utterly ridiculous.

The only oil company that I've heard anything like this is Mobil. It's not 100k ...it's 1000K on Delvac 1. Big banners reading "The 1000,000 mile oil!".
I'm sure Amsoil has had a few 100k OCI's in their testing ...and I imagine if they repeated it a few times with confidence, they would advertise it. I believe that they have various oils designed for various durations of use. 25k/1year is the current top dog, IIRC.
"Perpetual sumps" are nothing new with bypass filtration (TP). Under some circumstances, 100k would be a short OCI
So, ..YES..
Now I don't really recall any warranty work being requested or denied where extended drains were done by design (w/the aforementioned qualifications - bypass filtration and UOA) ...now extended drains out of negligence
...sure, plenty of them.

I'm gonna do my darndest to get there with Esso XD-3 0w30 in my GM 3.1L V6 engine.
Olympic has posted UOA's from a similar engine showing that 40k miles isn't really a big deal with the oil. So 100k isn't much of a stretch with proper maintenance of the oil level, and a couple mid-cycle filter changes.

At current price points, Yep, me too. However, if they can get $200/qt for the oil and $200/filter, I'm sure they'd jump on it, that way they could get all your money up front when you buy the vehicle.
But seriously, Pitzel is right on the money. Something like a tight Honda/Toyota engine, equipped at the factory with large by-pass and full flow filters, oil-water heat exchanger and a 4 qt automatic top-off oil tank could probably do 100K easy. Oh...can't forget the Esso XD3.

Hahahaha..no offense but the intake gaskets on GM's don't go 100K

10-20 years ago it cost me $330 sum total for ALL oil changes on my 85 Omni to 165K. This was 3K OCI with Castrol 20W-50 and Fram.
Yes, you could probably double that figure with today's prices, but I doubt they could design a 100K OCI for less.
Al also brings up a serious point. The auto industry should first concentrate on making parts like intake gaskets that would last past 100K before trying something as ambitious as 100K oil changes.

I always understood Mobil's claim of being the million mile oil to simply mean that by using their oils in every scheduled change, a diesel will last 1,000,000 miles before it needs a rebuild.
Not to nit-pick, pitzel, but Olympic went 40,000 kilometers on an oil change with XD-3, or 25,000 miles, so he didn't go past what current long drain oils (Amsoil) claim. But, his wear was so low, I agree 100% that he could have doubled it, without problem.
But Olympic runs quite a serious set-up with by-pass remote filters, etc. That, and the fact that his taxi cars do not see as much cold starts, contributes to his excellent wear numbers during long OCIs...

Sorta. They actually ran a few to 80,000 OCI with filter changes at 40k. Those engines, as you assert, went over a million miles without overhaul.
I was hoping no one would catch that (playing spin doctor

Are you guys saying that extreme long-life oil already exists? How does that compare with the sludged engines that pop up every now and then on this site? I'm talking about the links to photos where the owner didn't change out the oil until they came in for the 30K service. I'm sure many of us have seen these images. And I'm pretty sure some of them were with factory synthetic fill.
Anybody care to verify these claims made above with their new car?

If an engine were to become sludged the problem would show up in the used oil analysis report which would recommend that the oil is to be changed and the cause of the problem corrected. Therefore with lube oil analysis there is absolutely no risk with the 100,000 mile oil change program and problems are detected early on before damage occurs. In fact lube oil analysis offers better engine protection because it lets you know that you have a problem.
Heavy duty diesel engines and passenger car gasoline engines are different animals typically operated with completely different duty cycles.
When you talk about OCI's on one they do not apply to the other, regardless of oil chemistry. In other words, its not the oil, its the engine and operating environment.
Chevron calls Delo 400 a "million mile" oil and backs that claim with some kind of warranty. What they mean is that if you use their oil analysis service and change it when they say, they will warranty your engine to go 1,000,000 miles between overhauls. I doubt if they will enroll any passenger car or light truck in the program.

not the way i drive.
Mobil 1 did a test on a gasoline BMW engine that ran 1 million miles. Hoever the oil was changed every 7500 miles
Why would anybody even want to try for a 100,000 mile oil change? What kind of bragging rights does that give a person? How many times can you go into a bar and brag to everybody how you did 100,000 miles on one oil change?
Last time I checked you can get a 5 qt. bottle of Valvoline oil for less then 10 bucks. Four oil changes a year is 40 bucks. If you drive 100,000 miles in 8 years that is 320 bucks. This is high finance? How much does your car insurance cost in one year?
I think I would rather change my motor oil on a regular basis, use Auto-RX, and be able to brag how clean the engine was.
Now if some sort of technology came alone to make 100,000 mile oil changes a reality and safe, great. Lets start driving 100,000 miles on one oil change. Otherwise, I will keep changing my oil until fuel cell cars come along or electric cars or whatever.

You might make it to one (1) change, but I doubt you'd make two (2).
