Pete M Posted October 22, 2006 Posted October 22, 2006 I went to the Jeep dealership to get some GL-3 for my 90's AX-15 and found that they don't carry it any more. But that's not the important part, apparently the replacement is 10W-30 oil. :eek: I swung by the Dodge dealership and they confirmed it. 10W-30 is now the recommended oil for the AX-15 and it claims "improved shift quality" or something like that. I volunteer to be the guinea pig on this one since I have a high mileage trans to experiment with. You may have to wait for results though, as I don't yet have a floor... or brakes... :oops: But we'll see what happens.
jeepthing07 Posted October 22, 2006 Posted October 22, 2006 A Yota friend of my told me a long time ago that his toyota's transmission (Toyota version of the AX15) used motor oil. I never herd of any jeep owners running it though. My friend with a TJ ran ATF in his AX5 :eek: never seemed to hurt it. When i change my fluid i will try motor oil, its alot cheaper :D
bpm4x4 Posted October 23, 2006 Posted October 23, 2006 http://comancheclub.com/forums/viewtopic.php?p=12298&highlight=#12298 I found that out too, keep us posted on the results I may just run GL-3, it has worked fine for years.
Oizarod115 Posted October 24, 2006 Posted October 24, 2006 thats weird. gonna buy high mileage oil for it? :D
Pete M Posted October 24, 2006 Author Posted October 24, 2006 thats weird. gonna buy high mileage oil for it? :D Hell no. I'm using whatever cheap crap happens to be in the garage. :D
Oizarod115 Posted October 24, 2006 Posted October 24, 2006 Hell no. I'm using whatever cheap crap happens to be in the garage. :D nice.
Pete M Posted October 27, 2006 Author Posted October 27, 2006 Good news! (for my trans that is.) I found a few quarts of semi-synthetic 10-30 in the garage! :D Don't know how old it is though. I found it at the back of a shelf.
ekulrenlig Posted December 16, 2006 Posted December 16, 2006 So has anyone tried motor oil in the tranny yet? Results? Can motor oil be used in the AX-5 as well ('87)?
Pete M Posted December 16, 2006 Author Posted December 16, 2006 No results yet. The project timeline had to be sacrificed to the homework gods. In a couple weeks I'll be attacking it full on. :D
Bounty Hunter Posted December 16, 2006 Posted December 16, 2006 Can motor oil be used in the AX-5 as well ('87)? I'm guessing it can. I'll stick to my Redline MT90.
jpdriver1 Posted August 4, 2014 Posted August 4, 2014 sorry to revive an old thread, but I was wondering what the outcome was ----
nitroxsteve Posted August 4, 2014 Posted August 4, 2014 I have been running 10w40 in my Peugeot and 231 for a couple years now with no problems.
BootsNTrucks Posted August 4, 2014 Posted August 4, 2014 I have a AX-15 and 231 out of a early '90s Wrangler (internal slave) in my MJ. When I first put it in I was running gear oil like the Wrangler manual I had laying around told me to. I was just starting to have issues with my 5th gear synchro. Toyota buddy of mine told to try running 10W-30 fully synthetic. No longer have the issue. Truck definitively shifts much better now. Story I was told was the gear oil eats the synchro a real bad.
COMJNUT Posted August 5, 2014 Posted August 5, 2014 Can motor oil be used in the AX-5 as well ('87)?I'm guessing it can. I'll stick to my Redline MT90. I use the brother to the mt-90, the redline 75w90ns, been working well so far even with towing bails of hay on a heavy trailer.
benjy_26 Posted August 5, 2014 Posted August 5, 2014 I'm using Mobil 1 (or Super Syn, I forget) 10-30 in my AX4. Shifts like butter!
