Royal Purple VS. Mobil One

[Beaudee]

I usually use Mobil1 but couldn't find 5-20.I used R.P. for the first time and was curious how it rated to Mobil-1.My conclusion is Mobil-1 is better and cheaper.http://www.worldsbestoil.ca/dyno-test.php

You can find mobil 1 5w-20 at the autozone at josey and beltline in farmers branch/carrollton.

Yep just found it.I used the R.P. to flush her out :D .I'm sure its good, but doesn't beat Mob. 1. from what i researched.I think they call R.P. royal, die it purple and charge you good. :d I gave it the 50.00 royal flush! :rll:

I've used RP 5w-20 for quite a while as I was looking to go Mobile-1 5w-20 from the beginning, but it wasn't available then.

I've been running the RP in the transmission, as well, since 30K, and clicked 34K, today.

I figure you can't go wrong with either. It's a Ford v. Chevy thing, I suppose.

Just my $.02.

[Beaudee]

I had each to compare today by feel.My .02 is Mobil 1 feels like its ovulating,R.P. seems watered down. :rll: knana

Using the foloowing test criteria:
The Thin-Film Oxygen Uptake Test (TFOUT) measures the oxidation stability of engine oils. The High Temperature/High Shear Test (HTHS) measures a lubricant's viscosity under severe operating conditions. The NOACK Volatility Test measures the evaporation loss of oils in high temperature service. Pour Point indicates the lowest temperature at which a fluid will flow. Total Base Number (TBN) is the measurement of a lubricant's reserve alkalinity for combating acids. The Cold Cranking Simulator Test (CCS) measures a lubricant's viscosity at low temperatures and high shear rates. The Four-Ball Wear Test measures a lubricant's wear protection properties.

The best oils are Mobile-1 and Amsoil

Royal Purple here. :tu:

[Stinkbug]

RP is Mobil 1 with dye.

[PoorSvtman]

I feel that its all hype... Given im sure mobil is the top ranking but im sure there are other oils that are just as good if better that just havent seen the testing that mobil has done. Mobil is just the cult leader in oils on message forums... I bet most that say they use it realy dont...

5-20 is for the tree huggers. run 5-30 in brand new truck and 10-30 is middle aged ones. I ran 15-50 in my race engines for the extreme demands.

[PoorSvtman]

Mobil1 is API certified RP is not, I am not sure of Amsoil. 5-20 is for the tree huggers. run 5-30 in brand new truck and 10-30 is middle aged ones.

:tu: Exactly what ive done in all my cars/trucks

Royal Purple is ricer oil. It'll free up horsepower as much as new Japanese letter stickers on your fenders will. Mobil 1 for me...Royal Purple can go to hell along with all those ricers that use it.

Black Label is goooooooood.

Tom Why do you say it is "ricer oil" know something we or i dont?? Please share.

Just alot of imports guys use it... I know alot of the import shops i still deal with use it as much as mobil... The shop i used to work at sales it.....

Choosing oil is just like choosing tires... My theory is just like the typical PCV fixes.. On some trucks it works and others it dosent.... SO mobil could work for one motor and not for another.... Use what you want and what you feel comfortable with... Dont rely on the internet to make your decision

[skalywags]

what's the price difference and where does Valvoline and Castrol Synthetics fit in here?
I now even use Mobil 1 syn 2 stroke oil in my Yamaha YZ250. I pay 6.99 a quart vs $13 - 15 for for the other brands of syn 2-stroke oil.

[BC Lightning]

10-30 is middle aged ones.

Mobil 1 10-30 in mine, not sure if it's classified as middle aged since its a 2004

Of course it is always changed with motorcraft oil and fuel filter at 3,000

Not the import scene....just the ricers. There is a difference you know.

To a point the thicker oil affords more protection when driven hard. Thin oil is ONLY for cold start protection and fuel economy. It has no high performance value. We ran straight 50wt in our 30K dollar Reher Morrisson racing engines.

[Moonshine]

I bet most that say they use it realy dont...

WTF???? OK, I can see lying about sexual conquests, how much money you have, how quick your vehicle is, etc., but lying about what kind of motor oil you use? :hammer:

[my2002lightning]

I'll bet good $$$ this import's running RP, too! :D

Amsoil is API certified- I think they are close if not the same (Mobil 1, Amsoil, Redline, RP) its just a matter of personal preference.

My worst exp. was seeing pieces of a truck drivers wife who was impaled by the wing tip when the driver was driving around the a/c without watching where he was going.My personal exp. was, i was working on the rudder in a man lift @ the very top of the vertical.I was doing open-up for inspection.My last panel to open i had to move the rudder by hand and hold it to remove some screws.I chose the wrong place to hold the rudder, and a mechanic was in the cockpit, forgot i was on the tail and kicked on hydraulic power with flight controls on.All the flight control surfaces center with full hyd. power.My last two fingers on my left hand were broken in 8-10 places.My hand fully recoverd,i was @ fault because of lockout tagout.The only reason i still have a hand is because when we kick on hyd. power we bump it on and off quickly 2 times to allow for someone to get out of harms way if they didn't hear the warning .Its also nice to tell everyone around the aircraft when hyd. is coming on. :bs

Purple is my favorite color, but I use Mobil 1 exclusively.

For the money, Mobil1 is just fine. If you want to use RP, go right ahead, but I woujld extend the oil change to at least 10k, to recover SOME of your investment.

As for useing "exclusively" 5w20, it's not necessary like Terry said: Ford uses it to gain some on EPA numbers and for cold start protection (like we really need that down here). As long as the oil is API certified and changed regularly, you can NOT be denied warranty for using 5W30 or even 10W30.

I use M1, I change at 5k, and I've had no problems at all, even with the autocrossing. :tu:

Now, I've been told that Amsoil's tranny fluid is da bomb, and that I should change to that... :d
