This oil was suppose to be changed at OCI of 7k miles. Through some confusion, it was unintentionally run much longer. This sample shows 6,700 miles, but in reality: -13,287 miles on this oil -Run for 2.5 years -Much of it was in extremely cold conditions (-20 to -30) -Many short trips of less than 2 miles where the engine never even got warm -Probably 30+ hours of idling -Approx 5k miles of highway The first UOA at 101k miles on the engine showed nice results. These results show it was run far too long, although considering the conditions, this UOA makes sense and I suppose the oil performed relatively ok. The oil is Motomaster Formula 1 Full Synthetic 5w30, which is rebadged Shell synthetic according to the MSDS. Filter was a Toyota house brand.
