April 5, 2006Hi all.
I bought my 1999 F250 ext cab last week and am looking forward to adding some miles to it since it only has 45 000.
Couple of quetions.
Would changing the plugs help prevent this dreaded event of the plugs popping out
And is this motor sensitive to the type of oil you can run? I will be towing about 8000 lbs this summer and I want to switch to synthetic, but I don't want a bunch of seepage like happened in my last old truck when I switched synthetic.
