Now there are some people who run syn oil and take advantage of the long life possibilities of the oil. For some reason syn oil doesn't always last the 25,000 + miles ,but I guess lots of freeway miles is the trick.
I disagree, synthetic oil flows at much lower temps and doesn't burn off like dino oil. Synthetic oils contain no wax so they don't form sludge. Synthetic oils are also more shear stable... I could go on and on why they are better. I guess people like to cheap out on things like oil and taking care of their cars.
How is it cheaping out on the oil and taking care of our cars when some people do not need to run synthetics? So I am not taking care of my car by going by the warranty and changing my oil at 5K intervals like I am supossed to? I dont run syn because I am doing 5K intervals, it would be a waste to run syn for 5K intervals imo, do you not agree?
-I drive 62 miles round trip everyday to work, with 55 of those miles on the highway with the cruise set at 70mph. I am easy on the oil. Do I need to use synthetic for this?
