Back in the day, friend had a late 70's (79 I think) Pontiac, the subject of oil changes came up and he said he hadn't changed in 10kmi or so. I strongly urged him to get it done.
Couple weeks later he said he got it changed, and said, "I'm embarrassed to say, it had been 46,000 mi since the last change".
Daily drivers can go a very long way as long as they
have fluids, air, brakes, etc. Unfortunately that is too much to ask from many owners.
Next we need to discuss coolant flush! Some people say every 2 years, I say change once, somewhere between 5 and 10y!
Let's not go into trans fluid...
