No more snake oil Syntec after Castrol's engineers blew me off when I complained about all the lamp black in the valve-train area. (Two oil changes in 9 months) So much for their fallacious synthetic. One thing to remember, It's your car, your money whatever makes you feel good do it. The oil companies are out to make a buck and since loyality has went by the way-side, buyer beware! Even if you had your own lab, time and money, you'd probalbly realize it's mostly "marketing hype". While I can still afford Mobil 1 this is what I'm using in my Duratec and my John Deere. Paul 98 Mystique LS DMD
For what it's worth, startup chain-rattle in my '98 has never been longer than .25 sec with the Amsoil 5w-30 I run.
