Me and my dad went to Walmart last night. My dad was looking at MOBIL1 oil filters in the size for his truck. He opened a box and there was a fram ph3600 in there with a receipt. He opened another one and there was a Proselect in there. He was going to take pictures but a security guard was watching us on the camera and told him he can't do that. He took the oil filters and went back into the back of the store. He ended up buying a Wix xp from ROCKAUTO for $3.14.
