Here is my latest UOA from Blackstone Labs. The engine is the 2RZ-FE engine. This run had 75% city miles on the oil, and the filter was changed from a Mann to a Purolator classic after 5,000 miles. This is the old formula prior to the signature series label of 5W30. Oil was changed to Blain's Farm & Fleet 5W30. Please feel free to post comments or questions. Thanks!
"Ron:Thanks for the kind note. Your engine is looking really good. We're used to seeing low wear from Toyotas but wear this low after 11,156 miles on the oil is pretty impressive. Universal averages show typical wear after about 4500 miles on the oil. The internal parts are obviously getting along quite well. Sodium still showed up at 20ppm, but that's not enough to suspect coolant. The TBN was 2.1 showing some active additive remaining. Anything less than 1.0 is too low for extended use. Try 13,000 miles on the next oil. Nice engine."
