Skepticblog » Consumer Rant – Oil Change Interval: "For years, the recommended oil change interval for gas-powered cars in the US has been every 3,000 miles. This 3,000 miles interval is so well programmed into the psyche of the driving public that for many, drivers, mechanics, and dealers alike, it’s sacrosanct. I’m trying to break a superstitious habit.
Let’s start with the fundamentals – why we need to change the oil in the engine? Because oil gets “used up.” This means that after being in the engine crankcase, churned at high temperature by the crankshaft and circulated throughout the bearings, it will eventually lose it’s lubrication quality. This lost of lubrication is due to contamination from the engine (anti-freeze, unburned gasoline, metallic particulates from the bearing) and physical destruction of the oil molecules due to intense heat and sheer forces which the oil is subjected to."
