Good morning. I've returned from having the engine noise on my car checked out. The technician told me the noises were normal. I disagreed, and asked if they had any cars like mine on the property we could pull in and take a listen. He agreed, and found two, one new, one with about the same mileage. First was the new one, which was quiet. Okay, that's not a good way to prove you're right. Next was one with about 30,000 on the clock. It made all the same noises mine does.
Hmm...
You don't suppose the noises are because of the water-like viscosity of the lube oil, and the internal components are wearing more than they should, do you? The specified lube oil is 0W-16, and the latest models use 0W-8. I'm no longer feeling good about the potential lifespan of the engine, if we're all lucky, it may last the length of the powertrain warranty. The technician suggested using 0W-20 oil with the next oil change, but telling Toyota we're using the recommended type and weight. Then, we moved on to why my tires with 6,000 miles on them are wearing significantly more than they should. Since it was the end of the day, and everybody else had gone home for the weekend, he suggested getting the alignment checked at the next oil change.
