im just about to switch over to synthetic, and i am having the hardest time deciding which oil to put. i've read about those horror stories about engines getting raped because they didnt have ester oil, ive heard many mixed reviews about motul (mostly not so good), and think amsoil is super expensive. i dont know. i might just put that nissan ester oil in again until im really comfortable with an oil. im at 6k now

Well, honestly any quality oil (API SM) of appropriate weight isn't going to rape your engine, especially not in one change. By 6k, if it were me, I'd want to be on *some* kind of synthetic. Mobil1 wouldn't be a bad choice, or Castrol Syntec. Edit: or Mobil1 Extended Performance supposedly has the ester additives.

I wouldn't put too much stock in the good or bad results various oils got in the thread you're thinking of. There were far too few samples (in many cases, just 1 sample). We don't know what those engines were going through at the time, or how the mileage on them compared, etc.

Also, some of the results people are quoting are really from DE engines, not VHRs, which could change things as well.

If you're worried, buy some mail order oil analysis kits and track the oil in your car and find out how your choices do in your engine, with your habits, etc.
