2002 Tacoma V6, recently supercharged and tuned with correct fuel mods.
UOA initially showed slightly high Fe and Al, we assumed it was wear-in and it would all wash out.
The latest UOA indicates even higher wear. I am planning on reduced OCI and looking into a friction modifier like Motorkote.
Thoughts?

I guess so that Iron is out of site. The Silicon is unbelievable what kind of air filter are you using?

I will guess you have a intake leak somewhere or a insufficient air filter.

Perhaps a move a move to 15w40 may be appropriate with the supecharger installed? There would be higher cylinder pressures involved with higher connecting rod and crankshaft loads.

Id use an xW-40 oil in this application. Give M1 or Castrol 0W-40 a shot. Those are high numbers for a Toyota. Stay away from additives!

Stay away from Motorkote. Try Liqui Moly Ceratec or Archoil 9100. You could even try Redline Oil in 5w30 too. Try and check air filter. Get AEM Dryflow, Injen Nano, or Apexi Power Intake. No oiled filters!

I wouldn't throw any additive in just yet. Stick with the Mobil 1 but try 10w30 High Mileage for a 5,000 mile OCI. It's a more stout formula without going too heavy. I think it will help. Good luck.

Silicon high, fuel loaded sample. Bump up a grade for sure.

I would guess this is the TRD supercharger? It would be wise to keep an eye out for extra cylinder heads on craigslist or Ebay. If you must keep it supercharged. The 5VZ is known to go through heads and the supercharger makes it even worse. I knew a guy who had a '97 tacoma, TRD supercharged since 40K and went through 4 sets of heads within 300K miles.

Air intake system and fuel system requires attention and action , I suppose.

IIRC Trav had a similar issue with a worked Turbo engine tearing up oil and showing high wear numbers. I'd shoot him a PM if he doesn't see this thread and he can tell you what his fix was. A 5W30 PCMO didn't cut it for him either.

Running a K&N? Would help explain the silicon. You've also got some fuel dilution in the oil. Maybe step up to an xW-40 for a stronger add pack that will tolerate the dilution. M1 0w-40 has about 1,000 PPM of zinc and phos each, a fat dose of boron, and a whole lot of calcium to help deal with the blowby. Or even a nice HDEO would do. Track down the source of silicone first though.

You've got dirt ingestion from what the silicon number points to, and it is going up. This is causing your aluminum and iron wear most likely. I'd also step it up to a 0w-40 or 5w-40 HDEO. A 5w-30 PCMO may not be sufficient for stock engine + blower.

Hmm... I know guys like irv and a couple others always point to the M1 having higher numbers- maybe try the Pennzoil Ultra 0W40 that is spec'd for the Chryslers? Those cylinder loads are way higher than your Taco, plus you'd see if the whole M1 Fe thing has any merit.

But yes, most definitely you need to check air filtration. Go to a non-oiled fleece or paper filter and make sure there are no ingress points!
