Longest hybrid oil change interval?!?

[EffNo50]

Ohhh - and if you use Ford app - what does it show for the OLR% and estimated distance if given?

Only 21 mph avg which seems like city miles - but that 35 mpg makes me think decent highway miles.

My commute is only 2 city miles, to work, home for lunch, back to work and home for the day. I have a 3 hour trip (1way) about 1x a month to see family and drive 20 minutes (1way) to the next city about 1x a week. I listen to music while washing or working on my truck (except oil changes ) so that drives the average down.

OLM was 21%

Ya - I think the whole avg mph math doesn't work for hybrids - many of us know to keep it running in situations you'd normally turn a vehicle to Acc or Off. Because all it basically does is charge the 12VB rather than drain it - a good thing.

So maybe above 790 monthly mileage, 80% highway, for that 7514.8 miles. ETA: 884 miles.
So you are closer to the 1 yr time cutoff probably than mileage cutoff? ETA: Not.
About 9.5 months from last oil change? ETA: 8.5 months.

So it is interesting anyway - with 2308.2 being EV miles, about 30.7% EV usage.
ICE only has 5206.6 on it.

If you keep that up for the remaining 2.5 months - abouts 9492 total miles.
2914 EV.
6578 ICE.

And while some might complain you are over that 5K with a bunch of daily short trips and need an oil change - you have 1 weekly trip with total warmup, and very gentle long highway monthly. (probably great for 12VB charge up).

My 2005 Rav4 has 6000 m/6 month oil service. Not far removed from that.
(for anyone about to complain - no not comparing a Ford engine to a Toyota - but the oil now is much better than 2005 spec'd)

Oh yeah - for grins did the math if that 21% was totally based on mileage. ETA: this is correct.
7515 current for 79% usage - 1998 for 21% more - 9513 at 0%.
2920 EV.
6593 ICE.

Well - how about that. Maybe you are on a distance based estimate and not time.

ETA: Post that last oil change was almost 8.5 months ago - so this is NOT time based OLM, but mileage based.
My last bit of math for grins is the correct one.
6600 miles on ICE with modern oil and gentle driving.

You can do what you like to do and no one will complain. Post bad information and prepare for a tongue lashing.

I'm just enjoying my popcorn reading the thread.... I'm hoping people return to 3000 mile intervals. It's still good for my retirement investments. Ha!

All kinds of erroneous equivalents & logical inconsistency. Dunning-Kruger effect.

Kind of reminds me of High Skewl when some FULLY assert things they clearly don't factually know or supposition stuff to others on the keyboard. As if an expert.
Rather than a softer assertions what I believe (cause it sure ain't science!). they're using their own experience and opinions which we all do. To a degree. Meh

Basically a hybrid by its very nature puts the ICE in severe use through constant start/stop cycling. For our hybrid we are following the recommendation of 5,000 mile intervals and ignoring the supposed "intelligent" oil life "monitor". You have to remember that the oil monitor gizmo was engineered by the same engineers that couldn't (and still can't) figure how to stop all of the hybrid 12v batteries from causing the hybrids to go into deep sleep. Going to trust them same people with guessing on the oil's condition? Not in a million years.

You know what, I agree. I'm going to use a pencil and paper because calculators can't be trusted.

Anyway, see you all later, back on my horse because these gasoline auto cycles are loud and scary.

When I get home I'm going to fire up my wood stove because since I can't see natural gas, I don't trust it.

Last change was at 10037, Aug 17, 2025
5135.4 miles, of which 1224.1 were electric.

From other posts on here, time also factors in, probably for those that drive less than I do. I'm sure there's at least 2 calculations to meet the 10,000 miles or 1 year recommendations.

Since you cannot see nat gas they put "stink" in it that even with sinus issues you can most likely smell it. Be careful with the wood stove particularly if you have a piece of osage orange in your wood pile as it needs 2-4 years to dry enough to burn without popping and throwing sparks.

If your Maverick sat undriven for 1 year it will tell you to change the oil regardless of having zero miles changed. Goes to show that Ford can call it an "Intelligent oil monitor" to attract younger owners who swear that technology is so sacrosanct in life. Old school thinking is safer than relying on some electronic gismos supposedly combining miles, time, temperatures, and how many times a trailer plug was inserted. How about just changing the oil every 5,000 miles and be done with it?

You SHOULD change your oil annually even if undriven. Ask Jay Leon’s mechanic…

Since I drive less than 2000 miles per year - your “5,000 miles & be done with it” would not work for me.

It seems that most OLM’s are going to 0% at 10,000 miles or 12 months - whichever comes first? Is all the “intelligent monitoring” just marketing hoohaa? It is just an odometer/calendar monitor?

Has anyone driven more than 10,000 miles or longer than 12 months since previous reset with OLM still above 0%?

Has anyone had it go to 0% before 10,000 or 12 months? Hopefully severe driving would!

OP Surfstar - keep us updated as you approach 10,000

Edit: My OLM dropped 54% after just 900 miles of severe driving. But it was 7 months since previous change…seems it was calendar based?

Absolutely.

I meant your example was based on mileage, not time. Easy to see that 21% remaining is not 3.5 months.
Time is 1 yr max, mileage may float over depending on the factors.
Yours won't.

Context.

I was referring to one good example provided.
My info should be reviewed.

Is 6600 easy miles a bad interval?

You are missing some informative posts with stats provided if you still have those initial questions.

Plenty have gone shorter, my first one was, last one was not.

It's NOT 10k miles for the hybrid.

It is 12 months max. Or.
Whatever the usage allows if less than 12 months.

EB probably is 10k as manual states as max or 12 months max - unless it sees it needs to be shorter - and many have reported that fact that actually rack up miles.

But very true - we have a lot of examples of barely driven trucks who aren't even reaching 5k in 1 yr, so they do the 1 yr.
And I'll bet if they looked at their OLM - 0%.

But many of them are reporting it as need to do change at 5K or 3K - when the fact is they are hitting the 1 yr limit anyway - and the OLM would likely agree with them.

Has anybody actually had their mileage float past 10,000?

I’ve seen the OLM predicting more than 10,000 - but is that number as accurate as “miles to empty”?
