[QUOTE="UnleashedBeast, post: 14721957, member: 112023"] First thing, no reason to change what you are already using due to prior recommendations. My recommendation change is due to Amsoil's new AZF 0W-40 formulation. It's a bit more viscous at operating temps than their 10W-30 formulations, but flows a bit better on cold starts for those who drive their powerful cars year round in cold climates. NOACK Volatility barely increased and if as shear stable as their 0W-30 formulation, makes a kick ass lubricant. Think of it as a "blanket" recommendation that can do the job of all previous 10W-30 recommendations with one formulation. This is for simplicity to the masses. 0W-40 is more viscous at engine operating temps than 5W-20 and not recommended for stock internal NA cars used on the street (excluding Boss 302). Even the Track Pack GT can use 5W-20 when only used on the street. I also found no reason to recommend a more viscous lubricant than 5W-20 Signature Series for NA bolt on only cars used on the street only. My tests have returned amazing results. Even the valve train looked new after a near 10,000 mile interval using 5W-20 on a 100% stock engine used for 30+ drag strip passes. Had a best of 7.5 @ 92 mph. [/QUOTE]
