Universal averages are also at half as long as a 10k OCI. What’s your point?

Lol yeah that was factory fill bro. Hint: the mileage

Yes they warranty 5w30 like this, sheared down at 10k miles when it’s ready to be changed per the manual. This is factory maintenance per the manual evidencing that it’s fine.

There’s nothing in a healthy oil report that implicates timing chain wear… meaning the chain is gonna wear regardless of your oil performance. Changing early is still a waste and your timing parts will still wear out. Lol

You guys are crazy! There’s nothing short of a good pattern of results here. Nothing to worry about.

Motorcraft full synthetic 5w30 for the last two changes. Synthetic blend was used before that. I’m moving on now to Castrol Edge. Always use the MC FL920S filter. Motor has the Ford Performance engine tune and K&N air filter.

I think the blackstone just missed labeled that way that was actually 600 miles

Gets flogged every time it is up to temperature 👍🏻😬

This engine has a copper oil cooler. The lead is likely the gas additive.

Pretty sure the lead is from gas additive, I have used octane boosters in the gas and break in lube in the oil the last few changes.

Mileage that low on the engine, it’s probably still break in metals. I mean it’s a v8, lots of moving parts, and a corvette that hopefully gets driven hard. Seems fine doubt there’s much to worry about.

Well I bought a case of this 5w30 MC full synthetic so the next change will be the same. I’ll consider a 5w40 or 0w40 after that.

Perfect time to change it then, eh? It seems optimal that the oil's worn out when it's time to be changed and there is no indication of undue wear metals or contaminants.

2019 Ranger with the Ford Performance engine tune and K&N air filter that goes with it. OLM was at 8%. I had fuel dilution over the winter months OCI but none over this spring and summer OCI. Regular commute driving and a few road trips. Looks like the new 2.3 is shearing the oil. Not sure I...

Huh? Blackstone says soot is represented in the insolubles.

Soot looks fine based on the low insolubles in my UOA. I actually had higher insolubles in my 2014 N/A Pentastar with 7k OCI.

I change every 2-3 years on my 84. Top end is squeeky clean last time I popped the cover to check and oil always looks new despite a 1980s technology turbo and thrashing it.

Yeah the Ford tune requires 91 octane and a 36 month engine warranty applies from the date of install. Shearing based on the lowering of viscosity? Is this a don't care because it started as a 5w30 and is closer to a 5w20 at this wear level... my 2002 4.6L Ford took 5w20 and that stuff came out...

This is with the Ford Performance engine tune and the K&N air filter that goes with it. TBN is still good at 9k and OLM at 8%, 10k would be fine which is where the OLM would have been about at 0%. This is "normal" commuting and a few road trips. Motorcraft full synthetic 5w30 in and out, MC...
