Hey folks,
Just did my first UOA. I had a few objectives:
1) Find out whether 8,000km (Canada) or 16,000km (USA) is a reasonable OCI. Looks like 8,000km might be low, except that the KV100 on the used oil was really low.
2) See if I have a leakage problem or a loose air filter. I didn't.
3) Establish a wear baseline using stock oil and filter, and see how it changes when I start replacing those. I've switched to GC 0W30.
Anyone have any comments? Thanks.
According to Blackstone Labs:
"Universal Averages show typical wear for the 2GR-FSE engine after ~10,000 km of oil use.
This sample was in place over a slightly shorter run, and most metals stack up nicely with averages. Iron is
a little above the average, but 24 ppm isn't a troubling amount of steel wear. Iron tracks with use so perhaps
this engine just sees "spirited" driving or idling, something like that. A little extra iron may turn out to be
normal. We'll know more as trends develop, but for now, all looks good. The low flashpoint/trace of fuel is
harmless. Try up to 10,000 km next.
I have placed universal averages in parentheses. Universal averages were for 10,000km.

Edit. Note that I am aware my post is of suboptimal formatting. I will fix it when I get back to a computer - I did this by phone.
