Yes we've come a long way in oil chemistry and such but these engines have hundreds of thousands of miles and are 30+ years old. Change your oil every 3000miles or 5000KM.

That's a good vid, his point is well taken. Rings. Rings. And cylinder walls. He's got me thinking on the business of going with the T5 part synthetic. I had read once before that synthetics make more sense with new engines. Switching when old not necessarily any better.
