When my father finds a product that works, he is usually a customer for life. He also likes to make his children customers for life, for any product he finds worthwhile. That’s why I exclusively wear Carhartts to work, drive only Chevy trucks, and eat organic. When it comes to taking care of all the machinery we keep around our home shop, my father has opinions on the best products to use there as well.
My father only uses Evinrude XD 100 oil in our boats. It has always been an oil that runs very clean, with no smoke or odor. I guess I’m going to be a customer for life as well!
