Gen 2.5 trans fluid: SPIII or not?
« on: June 19, 2017, 08:48:18 AM »
Saw an interesting conversation on Facebook. Got me wondering...

I was planning on picking up the SP3 trans fluid at the dealer, but if the Eunos SP3 is the same thing and cheaper, I'm interested. I know it's good stuff.

The question is what's the official answer on which trucks do or don't require SP3? It's based on build date, I guess. Figure this would be good info for our search to find.

Plus, I don't have a copy of the FSM on my phone these days.

Sp3 always and for every montero. Sp3 at the dealer is about $1 or $2 more a quart, I can't remember the price on the Eunos. It won't hurt a gen 1 or gen 2 and is actually required in everything from 97 - 06. Piece of mind goes alot further for me. I also noticed a great difference when I took my truck to the dealer and had them do a full service with sp3.

The Eneos I linked is perfectly fine. It is SP III and known to be a quality equivalent. And actually believed to be the same stuff, different bottle, cheaper cost.

 Eneos cost more on our side of town, have Josh bring you some to the shop.

If Amsoil has an equivalent, i can hook you guys up as well.  Full disclosure, i'd make at least a dollar off each quart.  :P

Mods, if this is violating advertising stuff, please delete.  I don't make enough money to ruffle them tailfeathers.

Eunos here is $11 per quart. Mitsu branded is $20 per. I bet my evo trans that it's the same stuff. Gen3 and pajevo are each running 6L of it at the moment...

Check ebay for sellers with 1/2 cases or cases of OEM SPIII. A Hyundai dealer should also have it in a pinch.
Keep your cars analog.

I guess people simply refuse to believe that the Eneos SP is a known quality equivalent that is safe for use in our transmissions.

Eneos is the same stuff as SP-III. Trouble is, the SP-III can be had locally for $6 per quart at the local Mitsubishi dealer with no shipping and NAPA wants a lot more for the Eneos and they have to order it. I'd have no problem ordering either online as long as I had a reasonable expectation that I was getting what I paid for, it would show up before I needed it and the landed cost was right.

Has anyone here had experience with Amsoil synthetic ATF? I will be running Amsoil on the diffs and tcase and after talking to some guys this weekend at my friends shop they are huge fans of Amsoil products they use on their ATV's and their Mudding trucks.

I was pretty much set on going OEM SPIII (Mitsu or Hyundai) to fill my trans but then this weekend having conversations with those guys and doing a bit more research...it seems the general census agrees that Amsoil ATF for SPIII use is a win. I even came across this from researching where this guy did testing with Kia SPIII to Amsoil ATF and posted the breakdown of the test results using both on the same vehicle with the same milage.

I signed up to be a Amsoil Preferred customer and I can get the Amsoil atf pretty much cheaper than OEM SPIII retail price.

That's what throws alot of people off. Early on, it was a big issue with several people using different service centers or lube shops to get transmissions serviced and not much long after, trans failure. Most shops these days have learned, especially with the growth of import vehicles here in the states.

Hopefully before people do any services they find this forum or others to gain knowledge before they let just a random shop mess with there pride and joy.

 I remember someone on 4x4wire ran the Mobile 1 full synthetic ATF and the Montero scorched that fluid, they did a before and after oil pan photos as well.
