People are willing to pay $$$$$ for a new vehicle (or rather they're willing to finance lots of $$ for one) then they show their WILLING ignorant cheap side by going 15,000 miles between oil changes- running 10w30 when 0w20 is mandatory- relying on Auto Zones $40 code reader as an OFFICIAL diagnosis etc. I don't feel bad for people like the guy in the article. You could tell a person like him that with his type of usage he should change his oil at 4,000 Miles religiously and he would scoff and reply with something ignorant.
