Well, I have been thinking about the time when I have to sell my truck. I was wondering what people are going think when I show them that I have a special filteration system and have been running synthetic fluids since new. Also would be interested to see how people react to the fact that the current oil has not been change for 20,000 plus miles. 2 Things will happen most folks won't give a crap and not be interested in the filteration, and probably ask me to take it off! Or People will be dumbfounded that I have not changed my oil, and I will not be able to sell my truck, except only to another person that cares as much as I do!! Will see.
