Nope. She changed the AIR filter religiously, and followed a rule of thumb I’d mentioned casually about oil long ago. “Oil changes are a rip off. Three thousand miles is ridiculous if the engine isn’t loose to begin with. Watch the color of the oil. If it looks dirty, it is.” She took that literally, and when I was driving one day, as we refueled during a blistering run from SC to MO, she showed me the dipstick. “Looks like it might be time”. The oil was a dark caramel color, no longer Pilsner tan on the stick, and it was down almost half a quart. That was at 140,000 miles. I changed it the following week at 145000.” That little Toyota engine was bulletproof. We regularly ran it at near wide open for hours, crisscrossing the states as we travelled. The struts, brakes, window regulators, and two sets of hub caps kept falling apart, but that motor was amazing.
