True though about styles of maintenance. When synthetic came out, there was a guy I knew who put on 100K (from new) before changing oil (just filters at regular interals). He said the oil was fine because the MFG claimed it would be so :sure: I wouldn't do it...
Yeah, that's crazy.
I change oil and filters once per year in all my vehicles except for the Cherokee. I change the Cherokee twice a year because I use it mainly for work (hauling firewood and brush). The engine idles, tows, and goes off-road a lot. I pull an oil sample on all my vehicles. I bought the Jeep Liberty and Dodge Ram new, so I know what’s been done to them. So far my UOA always comes back good and the report always says, “good for continued use, sample at next interval”, lol. I go ahead and change my fluids once per year as specified by Amsoil. I run Amsoil filters and lubricants, which are specified for longer oil changes or (at 1 year intervals) as long as the engine is in good working order.
