How Good Is Redline?

bushman66 · 06-21-2012, 11:35 AM

I change the oil in all my vehicles (2012 370Z, 2001 Porsche Turbo, and 2002 Silverado) at 5K miles. Makes it easy to remember on the odometer. The Z and Turbo get Redline and Mobil1 Synthetic respectively and the Silverado gets plain old dino oil. The Silverado is currently at 150K miles, runs like a top, and the only repair I have ever done is a fuel pump at 100K miles. Doesn't burn a lick of oil.

Changing your oil at 3750 is silly IMHO, but if it makes you feel better, it certainly won't hurt...hell, changing at 5K is probably silly for that matter, but its an easy to remember system for me. Modern EFI engines put MUCH less contamination into the oil due to better fuel metering/combustion, and tighter manufacturing tolerances. As long as you are regularly getting the oil hot enough to burn off moisture (hardly an issue with our 370's HA!) modern synthetic oil is probably good to 15K intervals. If I was going that long though, I'd be checking regularly with oil analysis, but at 5K intervals, its a waste of money unless you are looking for something specific.
