oil life

[ChitownStang]

even though I do share the old school view when it comes to taking care of my cars with you, these are modern cars completely run by computers so I actually do think that monitor has some credibility.
Cars aren’t the same as the early 1900’s anymore..

Because E85 causes more fuel dilution than gasoline. Especially if you have forced induction the additional blowby, combined with Direct injection forces more fuel into the crankcase which breaks down your engine oil faster. Even NA, if you are running E85, you need to change your oil more frequently

I wonder if the catch can is more important for your oil life when you run e85

Perhaps slightly, but once the fuel is introduced into the crank case, it is being vigorously whipped/blended with the oil. The catch can is really just preventing the vapors in the crankcase from going back into the intake manifold/air intake.

Actually the computers controlling the engine makes it run cleaner, along with using synthetic oil that does not break down like conventional oils did back in the old days equals oil change intervals not being as important. If you like to change it every 5000 miles but don't get it done until 7000 for various reasons, no big deal.

Synthetic oil sitting in an engine for an entire year that never gets driven does not break down yet the monitor would tell you it's time for an oil change, but it is not. That oil would still be fine. What it boils down to for me is that the monitor is going to tell you to change the oil quicker than you probably need to if your car is only used occasionally, so I ignore it and use the mileage method.

Thanks, I’ve heard this before but forgot why:
I notice my oil life monitor go down quicker when I run e70 in summer months

But does the OLM sense you are running that fuel (I think not), or does it run down sooner when you are using that fuel because you are having more fun ... ?

I’ve posted this before, here it is again for those who maybe have never seen it regarding OLM operation and how it functions, per the shop manual:

The timer also counts down as the car sits. So for those wondering why their Oil Life Monitor is saying you need an oil change when you have only driven 500 miles since last oil change BUT the car has been in the garage for 6 months consecutively... The above is your answer.

So according to the OLM information CobraJet provided, the car is capable of adjusting the interval for flex fuel. And, really, flex fuel is nothing more than the percentage of ethanol in the gasoline. So it's not that big of a stretch to believe that E70 or E85 is being factored into the OLM strategy.
No real mystery it seems...

 

[WD Pro]

Yeah I noticed that

Is the Mustang a flex car though, or is that a generic statement from Ford, and not specific to the Mustang ?

Does the mustang even have the hardware to determine e content ? And if so, why do people add aftermarket kit to do so ?

If the Mustang isnt a flex car, it seems strange that the OLM uses that as part of the algorithm ?

Since it's difficult to find and very expensive if you do, non ethanol fuel is the exception, not the rule. This means that most of the fuel you can buy is at least 10% ethanol and up to 15%, making most cars flex fuel nowadays.

did an oil change at 29k miles and now i’m at 31k and i checked the oil life reset and it says i’m already at 33% is this normal?

My car was doing the same thing early on where I barely did 2000 miles in the first year and it was 9% remaining. Since I suspect Fordpass sends that info to Ford, I had to do the oil change. Blackstone Labs basically said there was a lot of life left in the factory oil, later when I did it again with a full synthetic, I still had the oil life dropping fairly quickly (mostly short runs in the islands). After moving to the mainland and using it more, I noticed the oil life is dropping much more slowly as I did a UT to Vegas trip in that time period. If you have an extended warranty with Ford, I'd keep changing when it says so to maintain your warranty. Doing an oil analysis will put your mind at ease if you want to run it longer (and deleting Fordpass from your phone so they don't get your oil life information, if they do monitor it.)

The monitor does not know you put synthetic in it. That thing does not monitor the oil, it monitors a programming and an algorithm. You can run the best, correct, full synthetic oil money can buy, or you could run the sbsolute cheapest, off brand, gas station 30W that’s been sitting on some back shelf since 1955, and the results from your OLM would be exactly the same.
