Just because a product is expensive doesn't mean it's better. I've been useing Wix filters in tractors that cost four times more than a Dodge Cummins,one has over 12,000 hours on it, that figures to 600,000 miles,most all of it hard pulling. No oil related problems and oil tests always come back good. Think I should spend $2000+ per year for filters or $400 with those results?Not sure of the oil filters,but if you soak a Fleetguard fuel filter in solvent till the blue paint comes off guess what it says underneath?One guess. IMHO Fleetguard has you guys bent over a barrel and is giving it to you big time.
