/forums/images/graemlins/laugh.gifDad's Texaco station was in Marietta, OK, but the Mobil station was in Plano, TX, where I know we had Mobil upper lube. /forums/images/graemlins/laugh.gif In the auto parts store (same building as the service station), we sold all kinds of oil additives and lubricants (and told customers that we recommended none of them). I also recall Mobil technical people claiming that there were only two additives on the market at that time that would do no damage to your car; those being Bardahl and Alemite CD2. And they claimed that the Mobil upper lube would do just as much good as those two. And of course, I have no way of knowing whether they were right or not. It was also not uncommon for customers to try oil additives and return requesting a refund, which we always gave them (money back guarantee on everything we sold). And the additive manufacturers refunded our money, except for Wynn's. They expected the retailers to offer a money back guarantee, but they refused to refund to us, so it didn't take long for us to drop their products because nearly everyone who bought one wanted his money back.
