1996 1FZ-FE
254,000 miles

Any particular reason these metals would be higher or just 255,000 mile things?

Haven't noticed any issues in operation, with this info, Blackstone staff said it was not a concern and to check back with another test and we can build a trend.

What weight oil are you running and how long (months) has it been in the engine?

5W-30 w/ aftermarket filter and it was in for about 3k miles and a few (6+) months. Switched to Mobil 1 5W-30 High Mileage w/ Toyota filter after this test.

IME, based on serial Engine Oil Analysis (EOA) results, a heavier weigth oil may provide better protection (ie: 10/15W-40,) in the 1FZFE.

It's been discussed a ton in the past, but IIRC in the same engine (1FZFE), in Australia for example, Toyota recommends a heavier weight oil (same air temp range) than the US model.

Running oil a long time also tends to build up higher wear metals of course. Only way to know is continue with serial EOA's to look for a trend.
