The problem is that used oil analysis really don't tell you much (if anything) about wear and deposits, especially deposits.
 
There won't be no stinking deposits.

Oh yes, the boogyman and his deposits.

If they were a issue in DI vehicles, what oil do they state you need to run in the manuals of those?

Are these the same deposits that everyone who runs conventional oil has in their engines?

No, I'm talking about these types of deposits on the intake valves:

Valvoline SynPower 5w-20 is 10%.

Something that's been confusing me is the listed difference in MRV viscosity between Platinum and Ultra in 5W-20:

Platinum 5W-20 MRV viscosity cP (C°) = 9700 (-35)

Ultra 5W-20 MRV viscosity cP (C°) = 11700 (-35)


CCS viscosity for both is the same at 4250cP (-35)


This difference is reversed for the 5w30, with MRV viscosity being lower for Ultra. Could the Ultra 5W-20 possibly use less % of esters and PAO than the Ultra 5w30?

yea and a whole lot cheaper!!!!


I'm going to disagree. Amsoil is targeted at extended drain intervals as is Schaeffer's. Having a high starting TBN does not guarantee extended drain intervals, its the TBN retention that matters. The most recent VOA of Pennzoil platinum showed a starting TBN above 12. From my personal experience it was good for 1/2 the drain interval that amsoil ASM was capable of with a lower starting TBN of 10 in my application.

Schaeffer's 7000 and 9000 have starting TBN's of 7.5 but excellent retention which is how they can last for upto 10k miles in some applications. If a high TBN was all that was required there would be vastly more extended drain oils on the market.

i also agree,,and ive seen used oil analysis from ams that is depleted in short order,no engine is the same when it comes to wearing out an oil.

VERY TRUE!

No arguments here. I can make it to 15k miles on what is supposed to be a 25k mile oil but thats it. Dino is done in at 4k to 4500 at best, 5k the oil was heading down hill.
 
Please get on the phone with Honda and tell them what you found. My olm lets me go 6,000 or so miles till i get to 15%. This is set on dino. You cannot delay!!!

Not bad, it will be interesting to see if Pennzoil Ultra 5w30 has the ~3100 ppm Ca count like Pennzoil Platinum 5w30. Looks like ZDDP was lowered a touch, but that could be Blackstone.
 
10% vs 12.5% volatility isn't that big of a deal IMO, and for direct injection, usually the engine is designed with a large enough sump and OCI to compensate for it.

VW's problem is not oil, but its engine design (turbo and direct injection). Oil may only reduce this amount a bit, a typical extreme German engineering with minimal to no fail safe margin.

Just go ahead and spray sea foam or carb cleaner on a regular basis, that's the only solution.
