There have been all kids of talk about additive clash and oils not working to their "full potential", or whatever other things that drove people to use one oil brand and weight. There are even people that still believe that synthetic and dino can not be mixed, or you can't go back once you use a syn or something stupid like that.
The car started and ran, and didn't explode. I don't own a butt dino, so sorry, I have no results there. I do, however, have cams that make me cringe periodically, the sound is similar to a wrench being knocked around the engine. The dealer said it only backs the bolts out on the 2GR engine, the 4GR is fine, meaning it's fine until it isn't and they won't do anything about it. Why or how it is affected by the oil I don't know, but ValSyn
Fill went in in December, and came out about a month ago. 80% of city/traffic and 20% of highway. The car can idle extensively, not shy to leave it running for a half an hour or more whlie I'm in the restaraunt or store with the family. Had a few sustained high speed commutes on this one as well.
Filter came out wavy, never seen them do that before, but as always it takes a lot of stregth to tear it.
The magnet collected about as much metal as usual.

This is how much came out of the catch can, did drain a little during OCI.

Thought there was varnish on the baffle, but no, just soot.


This is why I leave the drain plug stuck to the pan while draining.

This is the reason why I have to put a lot more oil in than the book says. It just keeps coming when you tip it.

This mess of oils can be only called a blend.
1qt of:
PP 0w20
Kengall GT syn 10w30
Shield 76 synblend 5w20
M1 0w40 FS
M1 TDT 5w40
Magnatec 0w20 syn
1/2 qt of Quicksilver ATV 5w40 syn
The rest was splashed in in turns until I got it to full.
PP10w30 syn
DELO 400 15w40, 10w30 dino
Magnatec 10w30 blend
VR1 20w50 dino
While the results were better than the one with PP , where the flip did the additives go lol.

Refilled with Napa 10w30, a quart of napa syn 0w20 and a quart of Delo XLE 10w30 (CJ4), another full went it.
