I've used Amzoil synthetic and Mobil 1 synthetic and can't really tell the difference. Haven't used Castrol.

I've always been a fan of Mobil 1. Whether it actually protects better or worse I don't know. I just know that when I switched to Mobil 1 on my last car, it fired up and ran so much smoother. I had previously used Castrol GTX conventional oil.

I've always heard to stay away from synthetic oils if you have any oil consumptions issues.

Amsoil 5w40 euro blend FTW

I've always used Mobil 1. At work we make stuff for Mobil 1 to "dumb it down" so to speak. I wish i could get my hands on it before we put our products into it.

DON"T switch to a synthetic oil in an engine with 159000miles. Enough said!
