I've run Amsoil before and sent out for an analysis. I changed the oil at 8,400 miles ran it for 11 months. I used ASL 5-30 and Amsoil's filter. I didn't need to top off. The TBN was nearly gone at 2. I can't see it going 25,000 miles EVER without doing harm to the engine. Going 1 yr yeah. Amsoil claims 25,000 miles or 1 yr for normal driving and 15,000 miles when driving severe service. Look up what "severe service" is. I bet everyone falls within that unless you are in FL and drive on hwys. all day. Severe service includes excessive idling, WINTER driving (cold starts/temps), stop and go traffic, towing, etc. Don't blindly follow Amsoil's claims. Doing oil analysis (many) will help you find out how far that oil will go in your particular vehicle, extending your oil change interval. Remember one thing, COST. Doing an oil analysis (one) costs between $20-40 depending on where U send it and what tests U want done. Amsoil oil isn't cheap, neither are their filters. There are other alternatives that are just as good and cost far less. Simply doing one more oil change with regular dino oil or cheaper synthetic oil per yr. (every 6 months) is better IMO. I change mine in the late Fall before winter and then again in the spring no matter what oil I'm using. Amsoil is a quality boutique oil, I've used it, but don't fall for all their hype.
