Godzilla oil change intervals

My f53 Godzilla is calling for an oil change at 3700 miles…. Is that normal? I though these things were designed for 10,000 mile oil change intervals.

10,000 miles or 12 mos. Must be triggered by 12 months of age. Thx for the digital copy.

The oil life algorithm monitors other factors than just miles. On our 7.3 the oil life went to 0% at about 9,500 miles.

I'm pretty sure its not at 450 engine hours... we have only owned it for 7 months, purchased used with 2000 miles. Must be due to 12 months of age I figure. We only flat towed once for 200 miles, and previous owner didn't seem to have it set up for flat towing.

I have some vehicles in the shop that get driven maybe a couple thousand miles per year.

They will time out on oil change however I have never and will never change on time only when I know the use history including the oil and filter type

The algorithm's that calculate oil life also factor in idle engine hours and any good quality higher end vehicle will have both idle and total hours on the display. Some record and don't display idle hours as well

I just had my 2nd oil change, at 9,600 miles, pretty close to one yr since last service. Changed air filter also. Engine really running smooth, no issues.

Yes if you toggle thru the screen, you will see engine hrs.

I have started looking at the water temp gage and transmission oil temp needle while driving. There isn't an actual temp shown, but the needles don't budge off there indication when warmed up.

The water temp pretty much stays to the left of the little thermometer symbol, the transmission below will warm up and stay just to the left of the thermometer symbol.

I think i counted 4 radiators behind the grille. I bet there is a fair amount of Engineering at FORD to achieve these stable temperatures...

Synthetic

Spend the extra few bucks and go with full synthetic oil. No matter what anybody says. Number of months won’t matter, annual oil changes are unnecessary. You can run full synthetic from 10,000 to 15,000 miles without issue ever. Everything else is just boulderdash designed to get more money out of you.

Ford recommends synthetic engine oil in the owners manual, at least for the 7.3L V8 which this thread is about. The oil must meet the newer WSS-M2C946-B1 specification (not older -A1)

What do you suggest I tell Ford when I ignore the dash oil change reminder running 15k miles between changes?

For some of us, 15k miles could take 2-3 years. Well past the annual required oil change requirement by Ford.

I agree. With unleaded fuel there is no where near the carbon buildup in the oil. Plus synthetic doesn’t break down nearly as quickly as the natural stuff does.

Not sure if this is the first oil change, or past that point. The oil minder of Ford is accounting for many variables to assess when oil life is zero. However, I have had oil changed in my car where the shop forgot to reset the oil minder. And, as a result, I got a false trigger. However, the oil minder is usually pretty good about "when" the oil should be changed. When in doubt, change it.

Fact! I would change it...it's a cheap option. The systems monitor oil temperature, RPM's and a multitude of driving conditions as well. Those 10 mile hikes up the 8% grade mountains at 45MPH at 4,000+ RPM probably equal 500+ miles of normal driving. Mercedes recommends 20,000 miles between drain intervals...NO WAY! I changed it at 7,000 and will do the same going forward. I was surprised to see it still had a slight amber color to it. Cost me $120 in parts. MB dealer wanted $675.

I just had one done at 1500 miles while getting a front end alignment and a state inspection required for vehicle registration.

Sooooo, what was the time interval between those oil changes? 12 months? 12 weeks? 12 days?

New RV was at 48% at 1,190 miles. Now at 23% at 2,640 miles. The idle vs run hours were odd at pickup.

I change anything with oil life monitor at less than 20% or 1 year, whichever comes 1st.
