My neighbor is a relatively good friend and she has taken her car to an "Iffy Lube" since new. You know, the place with decent oil but bad filters? I made her an offer. I told her to forget the Iffy Lube and all she had to do was pay the $20 for a jug of PP 5w-30 and I would pay for the Pure One out of my own pocket in order to make sure her car gets good treatment. Now she tells me she would feel better off continuing to take her car to Iffy Lube. She must have rocks in her head or know absolutely NOTHING about motor oil. I would jump on it if somebody offered me that deal. Comments welcome.
