Oil
Been reading about this Royal Blue stuff.....Have any of you tried it? Does it increase HP and Fuel mileage like it claims?
Help me decide wether I should give it a try?
1998 f150 4x4 4.6 10100 miles Truck runs really well...no mechanical problems that I am aware of.

I've tried different stuff like that in my Dodge van and never noticed a single thing. I think all the claims are nothing but bs and I wonder how they can get away with it.
Save your money and don't put anything in a good running engine that might mess it up. IMHO

My guess is on their claims they run some incredibly thick oil like a 15w40 and dyno the engine then run some 0w20 of their own and try and say any increase is because their oil/additive is so great, when it was really just the viscosity change that did it.

Run a 5w20 in there and forget it. Castrol, Motorcraft, Penzoil, it doesn't matter.
Changing it is more important than anything. I also wouldn't spend someone else's money on synthetic for any regular road engine.
