Anyone using Royal Purple MAX ATF?

[Dkevdog]

I just installed my mag hytek pumpkin cover and used Royal Purple synthetic gear oil for it. I noticed they have an ATF fluid as well and was wondering if anyone is using it. Heaven help us if I just started another synthetic :-{} match:{ !!

I've heard VERY good things...

about Royal Purple and would appreciate hearing from other readers.



I like my brand of Synthetic. I do not believe that it's bullet proof. I believe that there is always room for improvement - no matter how good something already is.



I'm very seriously considering switching over...

I'm using the max gear in the rear end and max atf in the transfer case. I don't think there's much way to tell a difference but I really like the royal purple product. I've used their Long Rider motor oil once a motor is broke in and thought it was great. Their tests show a small power increase but I'm just after the extra insurance of a top quality synthetic lube.

Another Reader...

who manages the National Parks Service Vehicles for Rocky Mountain National Park (dusty, dry environment) in Colorado (forget his name - very nice guy) does oil analysis for virtually every combination of air filter and motor oil for their fleet. He mentioned that he consistently get's better oil analysis when using Royal Purple.



He has the time, money (and responsibility) to try more oils and filters than the normal every day single user.



I really like what I heard from him.



I already bought 5 gal of Amsoil ATF to put in my new trans once it hits 5k... I think I'll sell it and give the Royal Purple a try.

alright fellas where do you buy Royal Purple? I would like to try it.

 

[Dkevdog]

Well I am going to go ahead an give it a try. I ordered a case today. For those who are interested, the best price I have found can be had at OILTOWN USA. They have both the ATF Fluid and the Diff Fluid for under $6. 00 a quart.

On that web site that was given, they only show dextronIII, and merconIII, they do not mention atf+III. If you use anything but atf+III you will get real harsh shifts.

I've been using RP engine oil for well over a year now with good results. The problem has been finding a source for it (no one locally carries it). I've found a rep a few hundred miles north of me here that comes to town every few weeks and will deliver what I need right here at the office. 5 gallon bucket of 15W40 for about $84 with tax. I can live with that.



Gonna start using it in the car, too.

Napa carries the Royal Purple line or they can get it for you. My local store has the ATF and gear lube in stock. Flying J truck stops carry the Long Rider motor oil if there is one of those near you, that's where I bought it.

Thanks for the links. ... and the advise on the weight oil for shifting.



I found a place in Ogden, Utah that sells it, but I'm not near the notes where I noted the contact information. There price was around the $6 range also.



What exactly is Long Rider? Is it Royal Purple's Fleet name or something like that?

 

[d90boy]

Long Rider is Royal Purple's heavy duty diesel oil. Check it out at:

No controversy just an FYI.



From the prices quoted, it sounds like the diesel oil is a petroleum product or maybe a semi-syn. blend.



I'm guessing the same on the ATF.



For a oil co to label it semi-syn. very little syn additives are actually required to tout this labeling (e. g. Vavoline Premium Blue 2000 is mostly pet. product)



ATF+4 is a semi-syn fluid according to several DC parts reps. (but twice as expensive as the plus 3 product).



Your diffs are factory filled with full syn gear oil from Dana/Spicer.



Judging from the price of the mopar gear oil (75w-140)full syn. It's competively priced with Torco, Amsoil and others.



I am a believer in specialty oils provided the company provides accurate data and keeps up with the API ratings for your application.



Good luck, Andy

Can this ATF be used in a stock transmission in a '98 2500 cummins? Every thing I read about these trannys says leave the synthetics alone. The guy at Dodge who reworked my transmission said they were'nt recommended. They say it messes up seals and hose connections.



I'm getting a lot of heat in the transmission fluid, towing on long steep grades [250+ degrees]. I've ordered a mag-hytec deep dish and a larger aux. cooler[if it will fit in there]. Rebuilding the transmission is not an option right now.



A guy from Lucasoil called me the other day about an email I sent them, and recommended their "transmission fix additive", saying it would decrease slippage and lower transmission temp. Does anyone know anything about this additive. I don't want to fix it, if it ain't broke!!

fluid

Andy, Good points of observation as usual.



Fish, avoid additives as you can not be sure of what all is used in them. Some additives actually use brake fluid that swells seals and can actually cause rust as brake fluid attracts moisture from the air. Use a good quality fluid like Amsoil, Torco, Royal Purple as they are made with the necessary additives, but without seal swellers. I recently serviced a trans that had Amsoil in it for 40K + and the fluid looked and felt new. Synthetic fluids handle heat much better and don't break down and form acids and varnish like regular ATF. Synthetics also usually have a longer service life. If you are not in a position to do all the upgrades you might consider at least a shift kit that will raise line, increase lube and firm up lockup. E-mail me if I can help or answer any questions. I am located near Dallas. My. 02.
