Sorry for the bad image quality.
The image is of the top of piston 4 and the cylinder wall in a Toyota 2AR-FE with 162,000 miles. All Toyota recommended maintenance was performed throughout the engine’s life. I have the feeling those recommendations were written by marketing people and not the engineers.
Based on what the image shows, the engine needs a short block. Am I correct?
It’s burning a quart about every 1500 to 2000 miles. Otherwise it runs fine.
In which case slightly thicker oil may reduce your oil burning but it’s not that bad.
Change your oil every 6k and it will probably last to 250k.
That’s not great but are you sure its being burnt? Oil can go other places and I’d believe a blown head gasket over a bad block unless there was some real abuse going on.
