I have a pretty long commute to and from work and put a lot of miles on my truck during the week. That means I'm due for an oil change a lot sooner than I normally would be. Because of that I'm thinking of switching to a synthetic motor oil to lengthen the amount of time and get more miles out of each oil change. Does anyone have a particular brand they like to use? Or even a brand to stay away from? Thanks for the input!
