Reply to "Oil leaks and oil change"

Back in the day, it was 30 wt summer and 20W in the winter,  Changed oil twice a year, at least.  Everyone swore by this.  Considered gospel.  Multi wt oil would ruin your engine, they said.  Even though 10W30 was commonplace in just about every other car.  As to what the real science is, I could not tell you.  Often myth exceeds science by a wide margin.
