I have a 06 Ford F250 SD with a 5.4L gas V8 with 26,000 miles that I have ben using 5w20 NAPA Syn.in.
I am going to start towing a 26' enclosed car hauler on a regular basis untill I can trade up for a Diesel.
This load will stress my little 5.4 a lot.
Will 5w20 protect my engine or should I switch to a 10w30?
A Ford master tech told me I should use 10w30 or even a 10w40!
What do you guys think?
