Does anyone have any experience with Royal Purple oils?? I was out looking for transmission oil because I was getting my valve body upgrade done and I ran across this oil. I've never heard anything about them so I chose to stick with Amsoil due to it's popularity and competitiveness with Redline. From what I've been told Redline uses something known as parafins(wax)....somebody correct me if I'm wrong(still consider myself a newbie)but that can't be to good for your transmission...can it??

 

Everyone has an opinion on whether it will work or not, formulations, BLAH BLAH BLAH. Unfortunately, the only significant oil analyses we've had performed here have been with Mobil 1 Synthetic ATF, which has yielded very good results. I have an initial Amsoil ATF analysis with 4k on it, but Blackstone only said to re-sample after 24k.

Soon, I will be sending in my Amsoil ATF sample with 16k on it (needed to drain it due to axle replacement), so we'll see how that held up and how much longer it should hold up.

Royal Purple isn't all that special from what I've seen. Competitive, certainly, but not a cut above anyone else.......


I think using Amsoil is a wise move.

 

Damn "THE MAN" I'm still being labeled. I just realized that I'm no longer a lurker......hahaha!!

 

I just bought their ATF, and I've used their Racing Oil & regular 5w30 SAE synthetics, for my last two oil changes. I see no adverse effects & the car runs smooth as silk! I think the racing oil is probably a little "thinner" than 5w30 & makes the tires scream in 2nd gear, in my auto gle. Probably in my head!

I haven't had a chance to use the ATF yet, cause I need a shop that can:

a) remove ALL of my old ATF (apprx 9qt)?

b) let me use my own ATF

I figured even if no one has tried it before, there has to be a "first try-guy"... so why not me? Try Jegs.com for good prices.

Changing the ATF by yourself isn't rocket science on the 4th and 5th gen automatics. All you need is a 19mm socket for the drain plug on the bottom of the tranny pan. Most here state that about all of it comes out on the first drain, although some say only 4 to 5 quarts.

If you're super ****, then you will want to drop the pan and clean all of the metal crud off the magnets on the pan. In that case, you will need to purchase new bolts for putting the tranny pan back on as well as a new gasket. If you want part numbers, please ask and I'll supply them....


Please do not use the RP racing oil past 3 or 4k. That stuff isn't designed for normal wear use and won't adequately protect your engine past that point. Extended drain intervals on Royal Purple or Redline racing oil is a bad idea. The additives are designed to break down relatively quick compared to even dino oils.....

I would also appreciate it if you would take an oil sample the next time you change it and send it to Blackstone Labs to have it analyzed. We currently don't have anyone on our spreadsheet who is regularly analyzing with Royal Purple oils (Lime is the exception, but an initial analysis will be awhile in coming).

 

i would appreciate if you could either post the part numbers or PM me. i am about to change out mine this weekend with some redline. my nissan service department seems pretty competent thus far but the parts are horrible. if i dont go in there with the number then i know i will be back later that day. thanks in advance.

 

==* Tranny Pan Gasket 31397-80X01
==* Tranny Plug 31377-31X06
==* (21) Tranny Pan Bolts 31377-80X09
==* Tranny "Screen" inside transmission (some think it is a filter, but it is not. Changing isn't necessary, but while you have the pan off, you might as well consider replacing) 31728-80X04

Those numbers are for 95 to 2k1 Maximas only.

 

Thanks, Bill. From what I've read, ATF should be 9qt total, right? I'm hoping to be able to drain all 9qt with one shot, without removing the pan.

I don't feel like paying for an oil analysis... but if you want I can send you an oil sample... I have some saved from my RP Racing oil #21 change. (it's been sitting in the oil pan for a 2weeks, though) I also have 2-oil filters (2nd & 3rd oil change). One of them is WITH a filtermagnet, and one WITHOUT the magnet. if anyone is interestedin "chopping" them up, I will gladly mail them out. I don't have the proper tools to do it & I would like to see if the filtermagnet actually captures anything. Anyone interested?...

If you wanna be cheap and not worry about changing the pan gasket/bolts, etc. (not needed unless you have a leak like I do from an incompetent Nissan Customer Care Warranty claim), then look at this thread:

A good pic that shows the transmission cooler return line:

You can also see the tranny pan and even the tranny drain plug if you look closely.

Greg's overall tranny cooler instructions can be found here, and have some other good overall pics of the tranny area:

U the MAN, Bill... The OILMAN...

Thanks,

I've been using Royal Purple stuff for a while now. I really like the stuff. I use the 5w30 and atf. I've run the atf for a couple of months now. No problems so far. IF anybody knew how to test the fluid, I wouldn't mind sending you guys a sample.

 

pan to remove most of the old ATF.

Here is what I do everytime I replenish my ATF;

1) remove ATF transmission drain plug and let old
ATF drain.
2) Install drain plug and put fresh ATF (~4 qts)

3) get underneath car and look at the hoses from
transmission to radiator. Driver side is the
return hose from radiator to transmission.

4) Remove hose at the xmission only coming from
driver side and put it into a oil pan.
5) Start engine and put transmission to all the
gears, without letting the car move!
6) Get somebody to watch the ATF being drained
from xmission to oil pan, until a gallon is
drained.
7) Stop engine , install the hose back and fill
up with fresh ATF (~ 4qts)

8) Start engine and move transmission to all gears
and measure ATF dipstick.
9) top it off to maximum as needed

 

NiCe tip! Thanks! Might even try it this weekend.

Skip the shifter movement while someone is under car. The fluid will shoot everywhere without someone aiming the hose into the bucket. The safest way to keep the car from moving is to keep it in park. Sounds like an accident waiting to happen and the risk is not needed. And if you want the flush to be more thorough, you can use more than 4 quarts for step #2. There will always be mixing in the TC, so you will need more than 4 quarts for a good flush. Even the best transmission flush machine does not replace 100% off the fluid. You also do not want to run the ATF pump dry. So measure output and shut the car off before the pan is empty.

 

I've ever done this before but I'm approaching 56,000 miles and I'm planning on doing this soon.

will two jackstands (both in front) suffice to do an atf flush?


How often should you perform an atf flush anyways?
