How often you should change oil for Hybrid engine?

[yamahaSHO]

Why does everyone (well not everyone) think the engine needs to get up to full operating temperature to evaporate water? Hotter temperatures of course speed up evaporation, but water will of course evaporate at any temperature that is above dew point.

Which is rarely hotter than 80°F.

Too much fretting over temperature.

How much water do you think is in there anyways?

mL or grams of water at most.

There is the time factor, and that is assuming you're not introducing more moisture into the engine. If it's not hot enough, long enough, it will not evaporate all of it. It's a good way to get sludge... I had that happen last year on my track car being driven on street. Had to pull the pan and clean it all up.

The last time I drained the AOS in the car, it probably had more than half a cup of water in it. It doesn't get a lot of miles either.

So I read in this forum that since the hybrid engine doesn't engage as much as the regular engine, you can just go with the recommended intervals which is about 7,500 to 10,000 miles per cycle. But according to this video, because the frequent start/stop and lower than regular operating temperature, it actually hard on the engine, so more frequent oil change is needed.

Thoughts?

I plan on changing the oil at 5,000-mile intervals from now on. Should it be even shorter?

Geez....every bit of HVB charge used was generated by the ice running while at almost optimal temp which in hybrid is rapidly achieved due to radiator shutters being closed and maybe delay of electric water pump engaging. The electric fuel pump will start before the ice turns on. When. It does start it's possible that the starter could turn it over a few times at 2 rpm if computer wanted to. Someone who had obd monitor running showing ice rpm at 0 when ice came on it was almost immediately at 800+. That 3ph starter spins it up fast but elect oil pump already has oil at pressure. The computer runs the ice often enough to keep temp of ice and cats at epa efficient levels. Also I notice on my lariat and my XLT LUX that ice comes on anytime I ask for 10+% power level. The truck is designed to start hundreds of times day. My temp gage on mine is at 2 always (maybe 3 or 4 on warmer days). ( I forget what the temp is at each bar is). I have no Issue changing my oil at 7k miles but feel like 10k-12k on hybrid would not matter significantly either. If you are worried about evaporating a little condensate, just put truck into ready state on park with e brake set and let it sit for a couple hours. Charge the 12v and cycle the ice 4-5 times. If you want ice to run without cycling off set AC to "LO" or "HI". (Don't run as long).

I have done 5,000 mile oil changes for 20 years now. Sometime around that time Consumer Reports did a review of engine oil and engine wear where they did 100,000 miles and then tore down the engines with intervals of 3,000, 5,000 and 10,000 miles. They found no difference in wear between 3,000 and 5,000. But more wear at 10,000.

3,000 mile oil changes waste resources and has no benefit unless your vehicle has extremely heavy use - like say always towing.

A little over 2 years with my XL hybrid with slightly over 42k mileage. I’ve done 4 oil changes(I change when the oil life monitor gets between 10 to 15%)

It's how mine works, daily driver and engine doesn't start until under full load 20+ mph not sure of the rpm as we don't have a gauge. But... it's well above the sub 1k rpm of a typical cold start.

Your hybrid gasoline engine starts at no load. Zero load. Always has. Always will. Do not confuse engine load with what your right foot on the right pedal is doing.

Just check the oil life on your Ford Pass app, or in the vehicle. At 10K mine said around 18% life.

Mine came with the engine block heater. My Maverick stays in a garage at night and I have been experimenting with the heater to see how much it helps out on a cool morning (8.5 miles to work on city streets). The manual says that 3 hours is the time to achieve max temp and over that time is wasteful. Not sure how much this helps the oil life (and cuts into the electric bill), but it is nice to start out warm. On a load meter it show between 300 and 400 watts.

I did mines at 7500 miles and I plan to keep that cycle. The manual says 10k but I figured 7.5K is a good mileage to change oil for most vehicles these days.

Do you check your dipstick at every fueling stop? Odor, color, condensation on the filler cap?
I live in a cold climate and have plenty of trips where its a 3 mile commute to and from with an eight hour gap in between. Maybe once every week or every other week would I put enough miles on to say I'm burning off some moisture from the crank case. I also have a block heater.
My rule of thumb so far has been at least twice per year, once in the late fall and once in the late spring which happens to work out to about 4,500 miles per change thus far.
Do what you will.

Some regard the above as fiction.

Like everything, it depends. I do mostly short trips with my hybrid but, I do a few long, light trips a year. Those long trips are with just a light canoe and some camping equipment. The long trips get the moisture out of the oil. So, I think I'm good for the 10k

Some regard the above as fiction.

And what's odd with that is the 24MY manual changes some of that up.
The 10K maintenance items are separate from the oil, and no chart for those oil changes now.
Brake fluid isn't mentioned now beyond checking it - which I'm guessing when done properly says when too much water present and time to change it.
And yet nothing changed between the 23 & 24 MY's - except stat's on what they've seen.
Perhaps better OLM algorithm but unlikely.
I like the chart for explaining why people might see differences.
PCM does indeed have a value for engine idle time compared to total on time.

 

[HeyBales]

I do every 5kish for the reasons stated in the video. Not to mention you typically Don't get a "normal" startup (engine idle speed) the engine doesn't startup until under full load 30+ mph. As far as can tell there's no mechanism to circulate oil in electric mode.

How are you able to get up to 30 mph in electric mode?
I mean if slight downhill no inclines I can slowly eek my way up to 30 and beyond - but I better not be the 1st at the light or I'd be getting horns blown at me.

Actually engine starts if you go above 10% load if battery is decently charged.
That's 10% on the power meter gauge.
If you think you are almost under full load before it kicks on - you are misunderstanding something that is happening.

 

[HeyBales]

I'm wondering how much of that info was not confirmed by him beyond just receiving it from Mobile.
The graph of temp differences - perhaps that's a specific hybrid with much bigger battery, or that was mere seconds display between temp differences.

Haven't had really cold days yet, but the morning of 40 F I did city driving to work 7 miles.
Had enough accelerations that required engine on, temp got up quick enough for me to have warmth - shortly thereafter the gauge/scanner showed 180 F, so I figured enough for engine.
Despite engine going off frequently for coasts and stops - never got below 178 I recall.
Perhaps after it came on for accelerations it stays on slightly longer than normal - I might not have noticed that.

I have a 2013 Fusion Hybrid, 217,000 miles. We have the dealer change the oil and rotate the tires when the change oil light comes on.

I think your missing my point. Regardless if it starts at 15 or 25 mph that's quite a difference from starting a car at idle. I don't really pay that close attention when the engine springs to life but I know it's not when I start it first thing in the a.m. and it starts at a higher rpm than I would typically cold start a vehicle. Just saying if there's no mechanism to circulate the oil in that condition it would cause more wear on the engine.
