SOHC engine must have synthetic and they must have regular oil changes, this keeps the tensioners and guides happy so the engine will live longer....like 500K miles type of longer.
Fun Fact, I have never seen a sohc engine fail in the bottom end, the bottom end is like bombproof. It is ONLY the timing and components that lead to early life ending problems on these engines.... avoid the 97-99 engines. I personally really like the 04+ sohcs, they are awesome IF YOU TAKE CARE OF THEM
Amen! Mine gotten synthetic since I got 156k and doesn't miss a beat. I've also been a bit mean to it as well (burnouts, “top speed†runs, heavy trailers lol)
