nothing was wrong with the red 4runners motor or tranny either, no HG replacement or anything, just keep in good working condition with standard maintainence, scheduled timing belt jobs, etc.....it was just high mileage and underpowered, thats why he wanted to swap.
it ran that long since he used only this stuff

was on sale at Wal-Mart!!!
I'm using regular Toyota motor oil thats semi-synthetic, changed every 3k.
