A few days ago when I was at work I saw a guy with an Amsoil hat. I commented "Nice hat" and smiled. He smiled back. He asked if I'm running their products in my car. I replied, "No, I can't find an Amsoil synthetic oil with the Volkswagen 503.01 approvals. (Their Euro formula only covers 501.01, 502.00 and 505.00) I'm running German Castrol right now." Before I could even finish he became like belligerent and asked in a loud voice, "So you don't want to save money, huh? With Amsoil, you'd save 4mpg on gas minimum and only have to change your oil once a year!" He acted outraged. I just kind of smiled and acted distracted by something else. He wouldn't drop it. He went on to say while yelling, "Aren't you tired of spending $25 every two months on oil changes? You know, the oil they use does your motor more harm than good. With reduced engine wear, longer time between oil changes and improved gas mileage, you'd save money over what you're using now..." I replied, " WOW That's very tempting. Do you have a card so I can contact you to perchance some of this oil immediately?" He handed me one and walked away without saying anything. Instead of attempting to answer my doubt about their European oils in my engine, he tainted my perception of Amsoil. What a complete moron.
