Blackstone Labs Oil Analysis Comparison at 10k Miles

Extreme Duty = Oil Change more often?

How would that affect warranty?

Don't overthink it.

Hybrids don't automatically require an extreme duty oil change interval as Master Blaster stated. Ford does not require it either. In fact, Ford warranties the engine using intervals according to the OLM or at one year, whichever occurs first. To suggest changing the oil that frequently with no mind towards duty cycle is silly.

Oil analysis data suggests Ford and the OLM monitor can be trusted and likely have a significant buffer built in, even when prompted to change the oil.

In other words, follow the manual and don't waste your money, your time, or the oil.

Extreme Duty = Oil Change more often?

How would that affect warranty?

I don't think he's saying it negatively affects warranty. I think he's simply saying that the warranty says using the extreme duty schedule is only necessary under certain conditions.
In other words, using the extreme duty schedule for normal operation in the Hybrid is overkill.


And FORD and the evidence backs this up . Ford's owners manual implies that the hybrid may be able to go even longer than typical under certain conditions due to the fact that the engine isn't running much of the time. Also, the hybrid engines in REAL WORLD use routinely lasts 250,000 and more .

True, but remember that a huge amount of that time with the engine on is done at well below optimum temperatures conditions, and it does 100x the number of starts compared to a gas-only drivetrain. It only partially helps that it is using 0W20 oil to get lubrication there faster. All Hybrids should be using the extreme duty cycle schedule all the time.

Why should they use an extreme duty cycle when the engines are lasting as long or longer than their other engines when maintained according to Ford recommendations? I understand your logic. BUT real world use says the opposite. These hybrid engines in REAL WORLD use ROUTINELY last 200,000-300,000+ miles. Ford has been selling hybrids since 2005. And the current engine is an evolution of the same basic proven reliable engine. Real world experience has more credibility than theoretical.

Some think all Maverick Hybrids should adhere to extreme duty intervals - others think that’s too extreme.

However, changing your Atkinson’s oil per the Extreme Duty criteria will benefit your engine. Certainly won’t hurt. Ok, call it a tie.

There are a LOT of things that won't hurt but are COMPLETELY unnecessary. Changing oil every 500 miles wouldn't hurt. . But REAL WORLD experience with the hybrid we since 2005 says that these engines tend to last 200,000-300,000 with 400,000 being realistic when maintained per Ford recommended intervals. Maybe using the extreme service interval will make them last even longer. But for most people 300,000 is more than the life of the vehicle anyway

Fixed it for you.

At that rate, you'll strip the oil pan threads long before the engine dies. Take the L buddy, no one cares except you keep asserting this with zero data or literature to back it up.

Now you've got me contemplating running my oil to 15k or 20k and doing Blackstone analysis.

As far as the Atkinson is concerned - I’ll concede and “take the L”. It appears to me on further reflection that even an abused Atkinson will outlast the Hybrid’s battery useful life.

In regards to the oil pan threads on my EB - I torque them knowing the aluminum threads are crap compared to steel. Same on the Atkinson.

I replace the drain plug gasket with a fresh one every time I change my oil.

I don't own a torque wrench.
I use my calibrated wrist to tell me what's tight enough.

I put in a quick change valve.
As long as that doesn't leak, I'll never use the threads again.

I had a quick drain plug on my Buick Encore. It was convenient with the lever, it didn't drain fast enough for me, compared to removing the drain plug. I never change my oil when the engine is hot so that doesn't play into it at all.
Personal preference.
Like the Encore, if one was already installed, I wouldn't remove it.

Thankfully, in most of the modern Fords the BOLT is designed to strip before the pan. At our dealership, we replace a decent number of drain plugs especially those that were overtightened by a zealous Walmart or jiffy lube guy. We hardly ever have to replace a pan or install an oversized drain plug. It used to be a lot more common in the days of the steel drain pans of the 1980s

Good to know. Thanks.

Thanks for that info on the drain plug bolt! I substituted an aftermarket steel bolt & steel crush washer at my first & second oil changes. Going to go back to the OEM bolt with the built in blue “rubber” washer next time.

Somehow I had a problem with stripped oil pan drain plug threads on my 2007 Lincoln MKZ. I was not changing my own oil at the time. I was quoted some exorbitant amount to replace the entire oil pan by the local mechanic, who was actually the guy who did most of my oil changes. So I asked him if he could drill and re-tap it with slightly larger threads, and he successfully did it for a low cost fix. It lasted another 9-10 years until I sold it.

My results received today. Sent sample 4/1…I made note of my concern about oil dilution because my oil cap smelled like gas…25 EB oil changed at 900 and again 7months later (this sample)…5W-30 Full Synthetic Motorcraft

“Chops: Thanks for the notes. The high flashpoint rules out any measurable fuel dilution in this oil, and there's no
evidence of water or coolant contamination, either. Wear metals are a little high for the interval, as universal averages
for this type of EcoBoost are based on ~6,100-mile oil runs. We're betting this Maverick hasn't had many oil changes
yet, though, so some extra metal could just be from parts wearing in. In that case, metals may improve next time. The
TBN is high at 5.9, so there's still active additive left in the oil. Try a 3K-mile oil run and check back on trends.”
