You could use the oil analyze service and actually know how long you can go with changing your oil instead of, again, wasting your money every 3k miles.Will Amsoil pay for the engine if it wears out after a few 12-month oil change intervals? Does that written guarantee apply to engines that already have 200~600Kmi on them before using the Amsoil? Is your truck exempt from any other fine print exclusions in this written guarantee? If you answered "no" OR "I don't know" to any of those questions... :shrug
Either way is fine in my opinion. I don't plan on analyzing it every oil change once I establish whats normal, and with this new oil I haven't had enough samples to know for sure. If wear is normal next time I'll skip one.Hmmm... $25 to change the oil? Or $50 to analyze it, THEN $25 to change it... :scratchhe
I vote hell no on that. Your gonna run an oil filter for 10-12k miles? And exactly what kind of driving are you doing and what Kind of oil are you using?I vote for 5-6k miles between changes. Oil filter every other. I'm using 5w-20. I drive my Bronco roughly 20k miles a year.
