Sorry for this
OK first off sorry for this, but im in my truck on the road so i cant really do a search,.
I have a 2011 F550 repo truck. Today I had ford do the oil change and they put 10-30 in it. Now that I have been driving a few hundred miles I noticed my engine is running hotter and I lost about 2mpg and 2 mpg on a truck that averages 11 is bad. So could it be the oil? This problem didnt happen until the oil change this morning.. I checked all fluids and there good. Should I switch out to the t6 5w40 or what? am I gonna hurt the truck if drive easy back the 160 miles to co springs?
