(DuckRyder) Thank you, thank you, thank you!!! for posting that thread!!!!! That thread had the answers I was looking for. (Gebo) & (Tony1679) "I guess I'm not understanding. Why propose all this nonsense to "avoid doing oil changes" just to turn around and literally perform the same exact task MORE frequently (you're still changing a filter and adding oil, it's literally the same amount of effort) shrug. Changing the filter is probably the hardest part." Your ASSuming, without knowing what vehicle I drive because you haven't bothered to read all of my posts in this thread. NO, on a 2003 Chevy blazer the easiest part is the filter change, the filter is right up front behind a panel easy in easy out. The harder part is crawling further under it to drain all the oil while laying on the concrete. It's hard for my fat [censored] to do that. Don't say it, I know I need to lose weight.
