You'd like to prove this how? Is this like the "don't change your automatic transmission fluid because you're just going to loosen stuff up and ruin the transmission"?
And why would any Coyote engine have sludge in the oil if people have been using the manual-recommended oil and following the...
Myths....synthetic won't magically leak out
Plus you have the high mileage motor oils (most of which are synthetic, or a synthetic-blend) with additives specifically for the old seals...
Nice video, but let's consider a few things. This cab is probably 2 years old. 120,000 miles in 2 years is a lot different than 10-12 years. The oil in the car was probably never over 60 days old!
And what oil did they use, exactly?
How often was it changed?
Why don't they show a comparison...
I'd like to see a valve covers off comparison of an engine that was changed every 5-6k, vs one that followed the OLM and was changed every 10k or so.
I can't imagine the 10k oil change engine will be as clean looking.
Edit: You can laugh, but have you seen how nasty the oil is that fills the...
So which weight oil did you mean when you just said
USING THE WRONG WEIGHT/VISCOCITY ENGINE OIL CAN DESTROY YOUR ENGNIE.
You need to be more specific when you say we should be using what's in the manual.
You have an entire build thread where you modify the car. But you won't give any reason why the oil should not be changed other than 'because ford said'.
Why? Why is it okay to change everything else?
If you think about it, factory everything is straight.
Factory tires? Ass. Factory brakes? Ass. Factory radio? Ass. MT-82 fluid? Ass. Suspension? Ass. Exhaust? Ass!
Engine oil is different why? No engineers work on the other shit?
