There are people who still think the Earth is flat, so we should remain skeptical of skeptics as well.
One piece of evidence is that it lacks the Dexos seal, which many new cars require.You know this is a REALLY IMPORTANT post here!
Not being used per OP direction so therefore anyone recommending it is "Drinking Kool-Aid".
Also, OP "Don't use this in new cars since that makes no sense". Disregarding the evidence that suggests otherwise.
Can't make this stuff up! ha!![]()
I’ll have before and after pics. Deep orange varnish. The fact that it’s getting cleaned up shows it is oil related.Looking forward to your write up, but very much in doubt that the QSFS caused the problem. I would also ask how much varnish we are talking about. I have seen more than a few K24s that have 200k, a visible layer of varnish visible after valve cover removal, but ticking along like new. I draw a wall between mild (?) varnish and piston ring deposits, impaction.
Many top offerings don’t get Dexos. PUP for example. Cost and relieving recipe is a turn off for them.One piece of evidence is that it lacks the Dexos seal, which many new cars require.
5K oil changes with the proper Ford stuff at 18K. only 2k away until the 4th oil change at 20k and it doesn't look good. Regular oils don't seem to do that well. I'd use Castrol or mobil EP, euro, or M1 ESP.Do you feel that any other oil at that OCI wouldn't keep the engine clean?
This ^But being this is an OIL forum, and we haven't really seen anything new or interesting other than off-shelf vs bloated boutique oils, this was a different type of product and to me interesting.
Let me just be clear in that I'm not saying it's the best oil in the world. It has limitations like any other oil.
I wouldn’t say just this forum. My opinion is API and Dexos aren’t stringent enough especially in the engine/piston cleanliness department.At one point I merely asked why so many people on THIS FORUM - not the world- would need it.
I was called a hater

I’m currently testing this theory in my Subaru. In about 40k more miles I’ll have your answer!I personally put far more faith in a product like Mobil 1 ESP 0w20 to not create a problem rather than VRP to correct the problem that may never exist in any meaningful way. Also VRP is always higher priced than similar products that some might suggest offer Superior performance.

An engine with some deposits on the oil control rings and drain holes = clapped out? Also I know you saw and responded to the post I made about 5k intervals using oem spec oil from the dealer on that thread about someone asking what to use on their new 3.0 ecoboost. You wanna tell the owner of that car that his car is clapped out from the control rings clogging at 18k miles after "doing the right thing" and using oem oil at the dealer at oem intervals?

I’ve maintained this vehicle since new with QSFS for a friend. Varnish visibly started around 45k at 150k now.Don't disrespect the green bottle.How long exactly was QSFS run before you decided it caused the varnish?
Castrol used to be well known for varnish but the UOA's were great.
