Here is my UOA I got from Blackstone today. My Pickup is a 1988 Toyota Pickup with the 2.4L 22-RE engine. The truck has about 200,000 miles on it. The oil is Castrol GTX High Mileage 10W/30. I used this oil for 3,368 miles, about 10 months which includes a whole North Dakota winter. The truck uses a quart of oil every 800 miles or so.
I bought the truck about 5,000 miles ago with a blown head gasket because the thermostat stuck closed and overheated the motor. We had the head machined and installed a new head gasket (along with other top end seals and gaskets). The oil was changed right when I bought the truck, again at 100 miles after doing the head work, then again about 1,500 miles later, then this oil, so all of that should have been flushed. I'm using a new Toyota air and oil filter. The engine runs great and does not seem to loose any coolant. I really like this truck and didn't exactly like the results of this test. I want to keep it for a very long time and do not want the motor to wear out before it's time (500,000miles?).
So yeah, thoughts, opinions, comments? Feel free to post them.
Blackstone called and said the wear is a bit more then average and these 22-RE typically do pretty well even with many miles on them. He also said Castrol GTX HM has a bit of Sodium in it but it shouldn't be that much, I'm not loosing any coolant.
Regardless I'm not going to get rid of my pickup or rebuild the motor, I'm going to just see how long this 22-RE will last. By the looks of my truck, it had a very hard life and while I do take care of it, I do like to have my fun too.
