Who said Royal Purple gives you a better 1/4 mile time? Now that is just funny

oh man, I didn't want to start an oil feud in here, was just curious about whether anyone had good or bad experiences with Royal Purple. I think I may be sticking to my Motorcraft here for quite some time.
I appreciate the detailed responses everyone sent as well as the videos. Even though, it seemed they were a little bias in the vid when the "leading synthetic" did not outperform the RP.

I too noticed the temp increase. strange....

LOL, these threads always start feuds.

I have an F150 with the dreaded piston slap. Changed over to Mobil 1 and greatly reduced the audible "slap". Cut the Mobil 1 with a quart of RP and noise is almost completely gone.

I've been using Mobil 1 for years in 3 different cars and trucks and it works great.

Interesting, I run 5w20 Motorcraft semi-syn. in my two 07s, F350 and Taurus, straight 30W Havoline and Rislone in the Cobra, Cougar and Boss, Royal P. in both JR. dragsters. I almost believe you could run any oil, if you let the engine warm up before abusing it and change it often enough. Pick an oil that works and stay with that oil. Remember, did it come apart because of the oil or something else that failed ...... :?:

Lots of street miles, a ton of passes down the track, I've never lost an engine due to oil failure, like a spun bearing, cam/lifters, sludged engine. The first 351W in the Cougar went 246K miles on the street, then I rebuilt it for strip. They polished the crank and I put std. bearings back in it. It finally broke a rod in the 8th season, at a Mobile 1 World Ford Challenge, no rebuilds. Old school, I know,

One more comment and I'll be quiet, for now. I use to run other oils in the JR. dragsters and change every pass due to alcohol contamination. They run real fat due to fuel system restrictions and load the engine with fuel, fresh engine or not. With the Royal Purple, we only change the oil at the end of each day, 2 passes or 10.

If you want a real good high priced full syn, go with Amsoil! It ain't cheap but it is good!

There's an interesting oil forum that you might want to check out. It's called "Bob is the oil guy"

Seems everyone is looking for some kind of magic in motor oil that will give them a boost in power. Truth is, especially in a daily driver, you won't notice anything. Any of the name brand synthetics will work fine as long as you change it when it needs to be. Any increase in power is so small even over a good dino oil. In a racing environment, that's a different story. A couple years ago where I was working, we tested a bunch of different formulations on race only stuff. FWIW the best power wise was Gibbs oil.
