Message: I thought I would try the Mobil 7500 this time around. i have been putting old fashioned dino oil in before. I bought a fram extragaurd 7000 mile filter to go along with it. I put 500 miles a week on my truck, so I wanted to try something that would last a little longer. Kind of an experiment. I will have to see how the oil looks after 7k on it.
