500K mile comparison between Synthetic and Conventional Oil on EcoBoost engine

[surfstar]

I think you would be right with an old school engine (No turbos, no direct inject) but I think you are fooling yourself if you think you can have long term reliability with Dino oil and long oil change intervals on a EcoBoost engine. I will be happy to waste my money on full synthetic and 5k oil changes on my Ecoboost engine. If you watch the video you will see all the piston rings are seized on the conventional oil motor. Sometimes it's more than the color of the oil on the dipstick.

I was more discussing the 2022 with 133k miles - I'd think that could handle 5k OCI on "dino" (most oils that meet required specs for newest vehicles are semi-syn) b/c they changed the oil 26 times in 2 ish years (if using 5k OCI). That was 1-2 months per OCI !

Clearly full synthetic is the way to go. Thanks for sharing.

This video compares running 2 Ford explorers side by side for 500K miles. They have the 2.3L Ecoboost. I have been running full synthetic in my Maverick since 500 miles but my difference is I change at 5k miles and not the 10K they did. This is about as good as you can get for real world comparison. Surprisingly they did not suffer more failures which is kind of surprising to me. I never considered Ford EcoBoost to be a 500k engine.

So,since 99% of people would never keep,or put 500 thousand miles on an engine I have two takeaways from this video. Save your money and use conventional oil, and,change said oil every 10,000 miles.

Absolutely correct.
If the oil were tested any other way than an equal Dyno laboratory way. Somebody would be bitching about how the two are different. I eat different drivers different days of the week different temperatures etc.
Why don't we do this. In order to simulate real world testing VS Dyno testing together in a lab subtract 250,000 miles.
It still shows that synthetic oil Superior.
