Longest hybrid oil change interval?!?

[Maverick123]

I change mines every 7,500 miles. I wouldn’t trust the oil life info on the App. It’s not a true reflection of the oil condition. It’s based on when the reset was applied after the last oil change. It’s usually set up for every 10,000 miles but if you reset it before the 10k miles it will think that there’s new oil and start calculating the oil life span again based on a new 10k range.

Why would anyone reset the OLM without changing the oil??

Just wondering how long people's Maverick OLM (oil life monitor) has gone on a hybrid.

My last change was at: 20,900 - current miles: 29,060 = 8,160 miles on oil currently.
OLM estimates 5900 miles to go

Means I could go over 14,000 miles on this oil change! Sweet. We'll see if the estimate holds...

I'm running a Fram XG3614 oil filter - which is good for up to 20k miles.
Oil: Havoline Lifelong 0W-20 - they only "guarantee" it for up to 10k miles. But it meets the Ford hybrid spec WSS-M2C962-A1, so it will last as long as the Ford OLM thinks it should.

The owner's manual says that you are required to change the oil no less often than every 10,000 miles to maintain the warranty. It also says that if the vehicle is used in severe conditions that a maximum 5,000 mile intervals is required. Some of the conditions they consider "severe use" includes use in very hot or dry dusty environments (such as desert areas).

Going by a sensor in the vehicle that supposedly tells you the oil's condition is foolish. Just get the dang oil changed regularly as it is cheap insurance.

It says 12,500 miles in mine.

warranty requires 10,000 max. My dealer does it free every 7,500.

Longest interval seems to mean for me as time not mileage.

So for me with less than 5,000 miles driven yearly it is exactly 1 year.

Dang - you're correct. I should have worded it better - basically most miles in a year while maximizing the EV miles is likely to be the highest.

I changed my oil myself last time and reset the OLM. Also easy to verify that the dealer/shop has done it when they change it.

"Your vehicle is equipped with an INTELLIGENT OIL LIFE MONITOR™ (IOLM) to take the guesswork out of your oil change frequency by using real-time data to determine when and how often you need to change the oil."

It's not foolish - it's INTELLIGENT!

Seriously people - oil and vehicles are much better than when you were young(er). Unless your specific engine has reports of fuel dilution or other issues, following the OLM is perfectly fine. Don't counter with "but FORD only wants it to last 36k miles" -- if you buy a factory extended warranty going out to 175k miles... guess how often you need to change your oil to keep the warranty intact? By the OLM.

People can rave all they want about how these modern cars are better and more reliable and you don't have to maintain anything as much as the old days.....but clearly does not work on vehicles for a living. Sure, you CAN go 10k miles between intervals, but oil BREAKS DOWN and continuing to run extended intervals will likely result in sludge, accelerated engine wear and COMPONENT FAILURE. And not to mention hybrids are EXTREMELY HARD on the engines, as the constant shutting off and on in some cases just accelerates the wear even more. As I always tell people though as an Automotive Technician, YOUR RESULTS MAY VARY!! The most common thing I see failing in modern vehicles is typically due to Owner Neglect. Best of Luck!

Since when is following the owner's manual... "Owner Neglect" ?

 

[HeyBales]

Question - is there any indicator that shows how many actual miles you have on the gas ENGINE since last oil change?

Pre-25MY Lariats, and 25/26MY get to see total miles and electric miles for Trip A/B.
Others get a per drive breakdown on turnoff.

So long as you reset a trip at the oil change - yes on those trims/years.
Have to do the hard math of subtraction of course.
But easy for them to see they have 5K on engine, no matter what's on the tires.

Are you talking for EB's or hybrids for breakdowns?

Might find the ample oil reports from hybrids to learn you are not correct.

Why would anyone reset the OLM without changing the oil??

I did it one time because the dealer set it at 5k interval, and I do 7.5k. I got annoyed by the constant reminder to do an oil change so I reseted. Once I did, the oil life went back to 100% but I knew the mileage I was going to change it so I didn’t bother with its fake “ oil life”.

SCHEDULED MAINTENANCE

Intelligent Oil-Life Monitor™
Your vehicle has an Intelligent Oil-Life Monitor that determines when you should change the engine oil based on how you use your vehicle. By using several important factors in its calculations, the monitor helps reduce the cost of owning your vehicle and reduces environmental waste at the same time.
This means you do not have to remember to change the oil on a mileage-based schedule. Your vehicle lets you know when an oil change is due by displaying a message in the instrument cluster display.
The following table provides examples of vehicle use and its impact on oil change intervals. It is a guideline only. Actual oil change intervals depend on several factors and generally decrease with severity of use.

(this is the table several refer to thinking it's telling them when to change - it's merely giving a clue as to when the OLM will likely call for the change already)

Maintenance Intervals

At Every Oil Change Interval as Indicated by the Information Display 1​
Change the engine oil and filter. 2

1 Do not exceed one year or 10,000 mi (16,000 km) between service intervals. Hybrid vehicles may achieve longer distances between oil changes, but do not exceed the one-year max oil change interval.
2 Reset the oil change reminder after engine oil and filter changes. See Resetting the Intelligent Oil Life Monitor - Vehicles With: 4.2 Inch Screen.

Incorrect? What was incorrect about what I said? You can try it yourself if you want. Anyone can reset the oil life by going to the settings on the instrument cluster. Everytime you reset it, it’s going to show oil life regardless of how long the actual oil has been in the engine.

 

[dsford]

Bro, this is BS. If this was true the oil life would show oil life when you reset it without changing the oil. But hey, believe what you want.

 

[BigOil]

I hear ya.

It's hard to break years of ingrained superstitions.

Mavester gets this stuff !!!

I really appreciate all the people that are changing their oil a lot. It helped with my retirement.

There's a lot of superstition around lubrication oil/PCMO. And a lot of history kinda reenforces some of this misinformation. And is often case don't confuse correlation with causation without statistical significance.

But I'm not making fun of any of it or anyone because I get it. Changing oil therapeutic and it's a great chance to inspect your vehicle and many want to do more for that big investment. Ask the folks in Dealer F&I sales office LOL

Here's the bottom line if you don't want to do testing like most "normal" owners do not --- unless they have an exceptional circumstance--- follow the OLM/interval & severe service rec's IF applicable per OEM/manufacturer, but make damn sure to use a non-Chinese OEM filter or better. And make sure you use a quality oil meeting the ILSAC API spec. Change it when the manufacturer says. Dealers have NO special knowledge BTW - BORING ADVICE!

I don't think one is crazy to not trust some quick lube places. But I actually I like Walmart because they have big dollars and if they foul up, they're gonna take care of it and they would never use under spec oil. They do training. So does Jiffy Lube and some of the others but it depends on how well they follow their franchise agreement. If you drive an expensive brand car (Benz BImmer etc), use dang Dealer. Although I think it would be fine to put $100,000 Escalade at a Walmart if you wanted to because it's not weird to typ American Techs.

Finally, if you have a car that leaks-burns oil and you never look under the hood, get somebody to check it between the long changes to make sure it's not consuming oil. Most dont but some do. Example- had an 08 RAV4 4cyl !! LOL
You can get a handle checking a few times to see how close you need to watch it to top off. That's probably the biggest risk of long oil changes although some cars have oil level sensors for this like BMWs I think. If it's your ditzy girlfriend or aunt Matilda and they're just not gonna do it then send them to a quick lube to look or top/overchange oil

Why is my opinion worth a fig: Almost all of my career with this stuff.

The company I worked for MADE base oil and additives (fuel additives too)- one of the largest companies in the world. I ran a blending plant among many other roles over time...

While our primary market was heavy duty engine oil, which by the way is rarely synthetic because it's really the additive package with modern basil oils, not the word synthetic, but that's the consumer signal quality.

I had an STLE CLS(tm) like the Internet guy. I also have degree in Chemical Engineering. We routinely as a team worked with the OEMs. All of em...
I remember speaking to very large groups on heavy duty engine & lube-grease, and things like that that were our focu$. I had a gig before I retired in sales support. Fun.

If we would stand around and have a beer after the tech talk and whatever the hell reason I was there---industry people would approach me and they would ask me about PCMO oil change stuff ( and fuel additives). Rarely convo with/about HDMO (the subject of the visit LOL)-- "oil testing is the answer" w HDMO at least enough to get patterns in a consistent use. Just like with dedicated PCMO enthusiasts.

Thank you for coming to my TED talk !
