Here's my first UOA for this car. 1MZ-FE VVTi with 231000 Miles.
Ran 3218 Miles on Delo SD 15w-30 and a Bosch D3422.
This is mostly on E30 fuel- I usually add a few gallons of E85 to my tank while filling up.
I had reused the oil filter and had like a quart-and-a-half residual oil from the previous fill- API SL Quaker State Defy 10W-30.
Viscosity is rather low. Sure, this engine is hard on oil, but I wasn't expecting it in the SAE 20 range.
After a few more UOA's, I'm going to replace the rear valve cover with a redesigned one with the spin-on PCV valve.
I'm interested to see how this is reflected in the UOA trends, since this supposedly mitigates the oil sludging this engine is notorious for.
