Pretty cool . They do this all over the place . At least no coolant traces in oil . Best info I see. And this is a Yaris engine 1Nz pretty decent setup that base a rally engine on same platform Toyota doesn't usually do that unless the equipment is usually worthy like JZ Supras etc etc
To be honest I was a little disappointed that the analysis was for only 3300 miles. What would be interesting would be to compare 5000-mile changes with 10,000 or 20,000-mile changes.
