I've just been doing some thinking lately, and it seems many people are somewhat confused in their thinking when it comes to the oil they put in their cars. Let's look at a prime example, shall we? I find many people are insanely obsessive over the oil for their brand new car, but the same people use whatever "cheap" oil they can get for their old and/or beater cars. Same thing goes for those dealing with fleets. Their personal car has to have something resembling the son of God's own blood, but the multiple work trucks, vans, and company cars get whatever is cheap and readily available. Now, you have to figure that the beaters, the work trucks/vans, and company cars are more frequently abused and demand more from their own motor oil, and the new/personal autos are going to be pampered and easily driven, until they reach a certain age or mileage. So, I raise the question of "why?". Please lend your view.
