Short oil life?

[mquick5]

I've heard members on here say they get almost 10k between oil changes. I purchased my 17 and after 3-4k miles it was time to change oil. Well we've only put around 4-5 hundred miles on truck since oil changed. And it's down to 68% already???

Truck runs fine and gets decent mileage. Does it's far share of curb idle thou, with the remote start.

It's a function of miles driven and days elapsed. Did you change the oil more than six months ago?

What do you mean its down to 68 percent? Are you saying it's consuming oil? That's normal on any vehicle. Are you sending the oil off to a lab? Just because the oil gets a little dirtier than the new oil, doesn't mean it's not protective. If you don't already have a catch can for your oil, it's strongly recommended to do so. Turbo engines put out a coking , the catch can keeps it from dumping in pan my The interval can go out to 10k, we do that on our fleet of Ford Transit 3.5/3.7 But in reality, 5k to 6 k is what's recommended for long engine life. Our members here all have different intervals that they feel comfortable with, but the cleaner the better for the long life of engine.

I change mine in my 2103 Ford F150 XLT V8 and in my 2017 Ford Expedition Limited every 5000 miles. I feel that this is right for my two vehicles due to my driving conditions.

 

[mquick5]

68% on the dash display. The oil is still full and clean. I dont have the catch can yet, but ordered one yesterday. I changed the oil in my Suburban last fall, and it still shows 65% on the dash display, I'm not sure how many miles without checking my log. But 32% life gone from 5 hundred miles seams far from normal to me. At this rate it will need changed around 1500 miles, per the dash display.

Once again, how long ago did you change your oil?

Well I've been living in a cave. So the 4 th gens actually tell you the percentage of protection in the oil? How the hell does that work? And what about the sensor that reads it? They obviously go bad. My outside temp reading is 10-12 degrees higher than actual temp. If I was you, I'd swing by your dealer or shop that has the equipment, and see if this is a malfunctioning system. New cars/trucks are getting to the point where they get the customer too involved. It's a good, and a bad thing. We've had internal combustion vehicles for 117 years or so, now their telling you a percentage for oil change . I think the old oil pressure gauge, and the reminder at 5k to change oil is where it should end. What's next, Tsb bulletins to come across your pop up video screen. Glad I'm not a service writer or mechanic anymore. I had enough guys telling me our job 15 years ago. What I used to love, was the customer said I want your $59.95 sparkplug tune up. It also included scoping engine. As I was asking questions, how's it run? Any loss of power, any misfires? The more I asked, that $59.95 tune up ended up usually around $200.00 to $300.00, after scoping.

From what I've heard ... No sensor that measures oil lubricosity. Its an algorithm (translation for Moose = Formula). Probably takes into account the number of milliseconds the engine has run as well as temperature, speed, whatever metric the computers can record.

This is one of those situations where the owner says ... Looks clean, has X miles, has X months ... All good! F that annoying notice that keeps popping up, I'll reset it

I'd copy and paste the link if I knew how. But you can Google "understanding ford IOLM" to learn more if desired.

Not running Kendall GT-1 Molybdnem Titanium blend are you?

On some it’s a fixed variable of time and mileage, many of the newer trucks use more variables in determining the oil life like temp and trip duration. My 2007 is a bit more basic and the owners manual says the following regarding the oil life monitor:

“Oil life

An oil change is required whenever indicated by the message center and
according to the recommended maintenance schedule. USE ONLY
RECOMMENDED ENGINE OILS.
To reset the oil monitoring system to 100% after each oil change
[approximately 5,000 miles (8,000 km) or 180 days] perform the following...”

 

[JExpedition07]

But your answer may be in my post mquik see the part that says “5,000 miles or 180 days”, at least for a 2007.....

It restarts the timer as soon as you change the oil, whether mileage or not.

Well if it's all based off a algorithm, then the mathematicians at Ford suck compared to Chevys.

And I used Ford synthetic blend oil. I will keep a eye on the oil level and color, but probably will not change it at 1500 miles. Also will be adding the oil separator as soon as I get it, weather permitting. I dont see this helping extending the oil% life on the display, but will help keep the engine cleaner.

Two methods for determining remaining oil life. Skip the first few paragraphs:

You didn't mention if you bought your truck new but I'd suggest that if it had some decent prior mileage and it wasn't changed often, then it's possible that you are still seeing the effect of that as the accumulated stuff (****) gets swept up and removed. The article Stamp posted would also seem to support that.

Often sellers will reset the oil-life w/o actually changing it; we all know why.

There's also a chance that it's gone rogue....maybe resetting will cause it to act right?

Purchase truck used from a Ford dealer, it was a certified pre-owned vehicle.

From pg 439 in our owner's manual.

"Your vehicle is equipped with the
Intelligent Oil-Life Monitor system, which
displays a message in the information
display at the proper oil change interval.
This interval may be up to one year or
10000 miles (16000 kilometers)."

pg 440
"If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or 5000 miles (8000
kilometers) from your last oil change.
Never exceed one year or 10000 miles
(16000 kilometers) between oil change
intervals."

Pg442
NORMAL SCHEDULED
MAINTENANCE

Your vehicle is equipped with an Intelligent
Oil-Life Monitor that determines when you
should change the engine oil based on how
your vehicle is used. 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 information 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.

Table Pg 443:
7500-10,000 miles Normal
Normal commuting with highway driving
No, or moderate, load or towing
Flat to moderately hilly roads
No extended idling

5,000-7,499 Severe
Moderate to heavy load or towing
Mountainous or off-road conditions
Extended idling
Extended hot or cold operation

3,000-4999 Extreme
Maximum load or towing
Extreme hot or cold operation

I check my oil often. I've found the monitor to be accurate on my Expy. I have changed around 7,500 miles. The level was good and the color was going dark but not bad. I'm using Fords synthetic blend.

I've found the oil monitor systems in a few of my vehicles to be good and I use it as a reference.

Ford engineers have designed these systems. I hope they know more about these motors than I do.

Also I idle very little. Only if I have to remove snow or scrape ice off the windows.

 

[JExpedition07]

I don’t get the oil change required message often because I generally change it early and reset. I do 3,000 mile oil changes because I use Motorcraft Synthetic Blend and Ford filters. Most of you probably use full synthetic with synthetic filters that can go longer intervals. I’m not pushing my dino oil blend that far.

I have no interest in switching to a full synthetic approaching 200k miles.

Service Computers have been around for a while.

My two personal cars. The Ford (10,000 mile or 1 year service interval) will be right about 6000 miles on the current oil change and right about 12 months time. Not sure how the algorithm works in the Ford or the Honda (lower photo) which has no mileage mileage interval, only what Honda calls the Maintenance Minder or 12 months for an oil change and is due for time-based service in May. Not many miles on the car the past year.

Since the IOLM is based on an algorithm ... Using measured parameters from the Expys sensors and counters ... Its possible that one or more of the sensors has malfunctioned.

The software program that does the calculations could have been corrupted also. Less likely but possible. All it takes is an particle from the sun to flip a bit and its a different program / algorithm. Or the temporary storage location that keeps a running tab of oil life.

Reset it, run it again, and if you get the same results ... Dig into it. Most likely a one time deal that will end up as big a mystery as a strange switch on the dashboard.

Someone with more knowledge and tools could probably see if there's any malfunctioning sensors. You might also end up with another unexplained issue (code) that could be correlated to this.
