I've seen a dyno run on TV where there was a few extra ponies made on a run. If I'm going for every last pony like for racing I would use it. Otherwise I run Amsoil thru out and have had great luck with it.

Royal Purple is good, but not the best. Of course, how can anything actually be "the best"? I use Royal Purple & Lucas Oil on my cars. Both brands are good. Front & rear differentials, transmissions, transfer cases, and engines.

yah i've heard good things about lucas as well.

so the general opinon is most any synthetic will do. nothing justifies buying RP over any other brand??

thanks for all the insight guys!

I am more than satisfied with the Motorcraft Blend, the 5.4 runs just as smooth & is just as quiet with the MotorCraft Blend!...............

And here's YOUR sign - risupercrewman was inferring that Mobil is the "world most greediest" company.

openclasspro#11 was insinuating that Wal*Mart is... Hence the statement about not shopping there...

I agree with openclasspro#11.

I really like the MC synthetic Blend! I notice no difference in the way the 5.4 runs in terms of smoothness & engine noise upon startup in the mornings, since switching from Mobil-1! I just turned 20,000 today! I've seen so many posts here about loud 5.4 3v's with engine noise, maybe I just seen to have a good one built on a Tuesday or Wednesday?..............

I agree - unless you are using your truck as a dragster, I honestly doubt that you'll have THAT much to gain from it $ to $. Now, as far as longevity? It's been said that RP is better than most, if not all syns. Is that true? Who knows. I would consider running it everywhere but my oil, which gets changed all the time. I can't see the benefit of using it in a dd.

Any gains, 1-3 MPG @ best, will be from a full fluid exchange. Not just engine oil. That means transmission, transfer case, front differential, rear differential, and engine oil. Some people also use the radiator additives that Red Line & Royal Purple market. I, myself, have used Lucas Oil Upper Cylinder Lubricant in all my vehicles.
