using 5w-20 Royal Purple Syn. since April '14, only have 1750 miles on the oil.....I've posted UOA's here of my 2008 F150 4X4 5.4l V8 that showed some dilution , question - would it be wise to stretch my oil change till next April '15 ?, I doubt I'll even reach 3000 miles then. should be OK, right ?
my posted UOA's are on this site, I don't know how to pull them up, PC illiterate
thanks
