Coyote 5.0 oil change interval.

[BP]

With VVT and all the problems Ford has with the 5.4 phasers I'd be scared of stretching it that far out. Now if every drive you make is 20+ miles and the engine warms up completely and is flogged regularly then yeah it's probably okay. It you putt around town mostly though I'd be worried about carbon and sludge buildup.

Go 10k and change just the filter at 5k.to make you feel better.

I used Wix and Mobil 1 on my first engine and it almost cost me the warranty. Ford gave the dealership some grief over it, but relented since the failure was not due to an oiling problem. I suggest these guys only use the Motorcraft filters on the coyote even though I think the Wix is marginally better.

Pretty sure that they cant deny a warranty claim if you are using oil and filters that meet or exceed the govt standards of what came in the car. but im no expert. I have heard that the motorcraft stuff is on point and used it pretty exclusively on all of the mustangs ive had without issue.

Oh yeah, we would have had a sit-down to discuss Magnuson-Moss, but it never came to that.

I'll say right off the bat this is a stupid thread, but what the hell. I've owned half a dozen modular motors through the years, non pi, pi, 3v, old 4v,

When did you own a 3V?

Most of my trips are short, but I don't putt. LOL

Bingo.

2006 Eddie Baur Explorer.

Ohh, I thought I missed a 3V Mustang that you owned. I didn't know those had 3V's either btw.

06 was the first year. 285 hp iirc. Drank gas like a mofo.

[Unicorn Jeff]

Well... if you were running corn then ever 2k miles

[Cooter]

I get freaked out about long service intervals too.

The 6.4 calls for 10k light duty, 5k severe duty. My trucks see ideal conditions. Cruising at highway speeds with some acceleration bursts here and there. But I still shoot for 5k and rarely let it get past 7500

[Blackpony]

Maybe I'm just stuck in the old days but I change my cars at 3k regardless of the type of oil. But I run Mobil 1 in the truck and mustang, wix filter on the truck and motorcraft on the mustang. The wife's car gets motorcraft oil and filter at 3k.

If I had a car with that long of a interval, I would change oil at 10k, but filter only at 5k and add whats lost. Synthetics are pretty good.

I have cut open just about every filter I take off my cars. Never hurts to look. Best filter was when I spun two rod bearings on race car... YIKES.

Yup! A filter will clean it right up and keep it going for a long interval.

I go 10k minimum, but I've also blown my shit up twice, so it'd be better to just ignore me.
