Last , if AMSOIL does cover damage / failure , would I need a special oil filter for a yearly oil change or would the TOYO ( Denso ) oil filter be fine ? THANKS
if you used the XL7500 and changed it once a year with 15,000 miles on the oil and in your hand you have the UOA from that drain stating the oil is still good , there is no way verbally the manufacture can void any engine related warranty.
same goes for any brand oil/filter you use. UOA reports say alot more than a glove box stuffed full of days wasted getting oil changes...
