Not sure where you live but presume DFW is Dallas Fort Worth( I'm from Canada and only speculating). You may want to consider using a thicker oil in the warm/hot weather. I'm changing my oil this weekend and putting in a thicker oil as opposed to a thin winter oil. We are in the low 70's and I noticed my pressure drop a little.


Good point, I just changed the oil not to long ago. I put in a 10w30. I may try a 10w-40 next time. I don't mean to sound like a dumbass in this question, but I bought the truck from my dad and I don't drive it everyday because I have a work truck. Which really sucks because I really like to drive the truck. The sticker in the window from when my dad owned said 10w-30 so that is what I got.

I just wanted to make sure I wasn't developing a possible problem. The truck runs great, has no leaks, and the oil level on the dipstick is right on. Thanks for the input guys.
