Just went to Autozone and they have a heck of a deal going on.5 qts of castrol syntech (5w40)and free oil filter under $25. Its suppose to be a k/n filter but will substitute the filter if not in stock. I got 10 qts and 2 filters for under $50 bucks. Regular price would have been $103 for 10qts and 2 filters.Like a used car salesman told me once-This deal is like a sore d_ck,you just cant beat it!!! LOL----------------Dave
