I’ve gone slightly beyond 5,000 miles a few times due to health issues, but I’ve always been hyper vigilant about oil and filter changes, so that’s very unusual for me.
I’ve never owned a vehicle that required synthetic, so it was using dead dinosaurs & foliage. And I’ve always believed that keeping fresh oil and filter in the motor was much more important than the brand, so it’s always been either store brand or whatever’s on sale. For filters, I’ve always done the same, but I’ve noticed that Walmart no longer carries store branded filters, so I’m using Fram.
The only thing I’d never use is fleamarket or yard sale oils and filters. I have zero confidence that the contents actually meet SAE and API specs, and since I got my “gold Rolex” at a fleamarket for only $15… well, you get the idea.
