Oil quality and change frequency

[barron64]

Jumping into the supercharger/oil pump gears install on my 18 GT, PP1, 6sp, with 74k miles. I can tell you up front, the oil pump gear swap is not an easy or quick process. However, I figured I would show some interior engine pictures of what engine deposits have occurred after running mostly PUP 5w-30, Motorcraft filters, plus Ceratec, for the last 8 years. I change the oil when the MIL light tells me so roughly every 9-10k miles.

Looks very clean right?

Yes, very clean. No need to change your oil, all 10qts, every 3-5k miles. Just wasting money.

Depends on your driving conditions etc

Highway miles in a warm weather state is different than cold weather, stop and go, short trips etc

Whats the oil analysis say? Looking at the insides of your engine doesn't seem to be a very scientific way of testing your oil change interval. I've never ran 10k intervals on anything. Not that i wouldn't ever, but i'd need some data first.

 

[barron64]

Haven’t done an analysis. Just an observation on how well good synthetic, good filtration and regular oil changes, keep your engine clean.

What if you race the car and keep it at 8,000rpms for 20 minutes straight getting the oil up to 290-300*. You think that oil can go 10,000 miles?

Change it as you like. This was for average city/highway driving, running it up through the gears a few times a week.

So then it's more about actual usage rather than mileage? Saying someone doesn't need to change their oil at 3-5k and that it's a waste is a bit misleading.

It does look like new in there

This is just wonderful news.
i've been changing engine oil every 3k miles in all my 5 S550's.
Enough of it!

Do you use an engine flush before draining the oil?

Did you replace the pladtic chain tensioners with metal ones?

No need to flush.
