Hi,

Finally managed to get my car working again... for temporary purposes, I put in Lucas 75W - 90 fluid in and I’m thinking about replacing it with 75W-85 Mitsubishi OEM. How long can I have that in there before my synchros get eaten up? Also is the Mitsubishi OEM gl-4? It just says it fits EVO 8-9 and 3000gt so I’m not sure. Thanks

Gl4 is the right spec. Not sure on length of time and damage its doing. I do know that using a standard gl5 instead of 4 has ruined a bunch of tranny's for other manufactures notably Nissan pickups and some european cars. Many dealerships and lube shops weren't doing it right. If specs of fluid say yellow metal safe or gl4 you should be good, change out as soon as possible.

I think I ran mobil-1 for a while and it's not the right spec and I don't think I messed anything up. I also am pretty easy on my transmission though so ymmv. I'd say no rush, but take it easy on the shifts until you change the fluid out. After the mobil-1 I used a certain type of motul that is GL-4 certified. Not sure how it compares to OEM fluid in price, but it might be worth looking into. I think it was gear 300. Might be easier to get than OEM too. Ran in my lancer well enough.

MZ320197 is the OE part number for the 75w85. The list price is $13.50/quart.

No chance in hell you can get it for $4/quart. That's less than half the cost. I work at a Mitsu dealership for reference.

Agreed!!! My local dealer would only sell it in like 5 gallon buckets for $$$$$$$$$$. I have been using royal purple 75-90 with no issues. 2 new transmissions in 2 separate cars. 200k out of both.

I'll buy some this week and send you the receipt. If this is the case, I will buy out the whole shelf. I just bought three quarts before Christmas. The dealership just gave up their Mitsubishi dealer status.

Ok, forget what I said. I bought and used the wrong damn tranny oil. I bought the Mitsubishi 75w-80w. Manual calls for 75w-85w. Good thing is I didn't drive the car but 4 miles when the engine blew the day I changed it.

So they sold you fluid below their cost just to get rid of it?

They sold you unopened bottles of Mitsu blue top fluid? 75w80 is even more expensive at 15.50/quart list price. This dealer you're visiting sounds questionable but if you can save the money and it's legit I'm all for it :LOL:

Well they did give up their dealership status. It's now just a used car dealer that is owned by a Chevrolet dealer in my town. So the fluid I used has a thinner viscosity to the spec fluid. Are you aware of any Mitsubishi models that could use this? I did find the correct fluid on AMperformance website for 16.00 a quart plus shipping.

I guess I never noticed much before, but GL-4 fluid seems to be all around expensive. Doesn't matter which brand, Redline, Mitsubishi, Motul, Royal Purple, etc. It's all $15 - $20 a quart. Geez. Was it always like this or are prices going up because less cars seem to use it now a days?

Use Red Line MT-90. It's sold on Amazon.
My machine shop should have my engine back to me soon. The owner of the shop doing my rebuild has been out for a month after getting injured. I think I will go to this tranny fluid when I install the new engine.
