Advance Auto Parts in my town (Terre Haute) has 5qt of 0w40 mobil 1 synthetic and mobil 1 filter for $29.99!!! You can purchase more than 1 of the specials!!!! So 2 times the money is $59.98 and you end up with an extra quart and an extra filter. I just bought 4 specials so i have my next oil change and 3 extra quarts and 2 extra filters for $119.96!!!!! A flippin steal!!!!!
