Hey everyone, so here's the question, should I go with regular Honda MTF or Mobil1 synthetic for my manual transmission? Would I notice a difference between the two?

I'll probably change the fluid every year.

So let me hear your suggestions.

I used Redline MTL....Great stuff. Used it in the Civic and have used their gear oils in the transfer case/rear diff of my Talon.

Yup... Red Line is good stuff, a bit more costly, but worth it.

Redline is hard to come by in my area. Plus Im just gonna change it every year.

Oh I forgot to mention its Mobil1 Synthetic motor oil compared to Honda MTF.

sorry... not sure how those stack up agianst eachother

If it was me, I would probably go with Honda, but I have no specific reason to do so other than trust for Honda engineering, which is actually dwindling at the moment.

I use 5W20 mobil 1 full synthetic oil for my 02 civic Ex (manual) THE BEST STUFF! didn't know that Redline made car oil too. I work at a harley davidson dealership and we use Redline for the M/C's. I hear it's good stuff. But Mobil 1 supersyn will do it for me.

Hey:

I'm going to do my MTL tomorrow, and Redline MTL will go into it yet again. If you change it every year, your tranny will be like butta.

If its not available in your area, just *call redline* in NorCal and they will send you whatever you want factory direct. It was awesome buying a case of 5w20 oil and having the fedex guy cart it right to my door.

Also, I have started hearing some very very good things about BG Products SuperSlick II mtl... If I can find some I'll use it next year, but right now I have just about exactly the right amount of RL left for a change.

Seriously, use the RL and you won't be sorry. If not RL, go with the Honda stuff as the mobil 1 5w20 in your box wont be sticky enough for your synchros to hit properly, and you'll gain a new appreciation for double clutching.

Hope that helps...

Go to GM and get their SynchroMesh Friction Modified Tranny Fluid, works really well. My buddy used it in his 00 civic, and my barber uses it in his Accord. Most civic owners in my area use this and love it. Amazing grindage protection. Amsoil is supposed to be good too, its considered a direct replacement for Honda MTF check it out at http://www.amsoil.com/scripts/runis...amsoiloaf:index

Great to hear all the suggestions, but I think Im gonna go with Honda MTF unless there is a noticable difference with synthetic motor oil.
And I dont want to order from the US cause the duty fee will be almost half the price of the product.

Also, when you change your MTF, do you guys lift the rear of the car as well?

 
Rep Power: 286

unless you measure out exactly 1.6qt in a seaparate container, the car must be level when filling the tranny with fluid. you stop adding fluid when the fill hole overflows, and if the car isnt level, you wont get the correct amount in.

^^^ What he said. If you just jack up the front, you'll have not nearly enouh fluid in and thats bad, mmkay.

I dunno if this matters, but if the rear end of the car is up too far, you'll be able to overfill slightly. Don't know if that is a good thing or a bad thing, but its just my .02 that I used 1.7-1.8 quarts (Maybe .2 quarts too much) today and the tranny seems to run fine. Course I did make sure the car was as level as I could and let a little dribble out of the hole before I screwed the bolt back in...

In any case, I talked to a honda dealer guy and he basically said that since honda doesn't put filters in the MT's, change the fluid every year / 12K miles or so as teh car starts to get older. I think thats not such bad advice for teh DIY-er as it takes maybe 45 minutes to do it and you get a lot of peace of mind out of it.

I think 12 k is a little to soon, sounds like a honda dealership to me.

^^^^yep, +1 rep for you for knowing your stuff. I would say the general consensus is that this is the best stuff. It is hard to find and expensive. If you don't know what you are looking for you can get the wrong stuff. It has to be GM Sycromesh FM, it must specify FM on the bottle. Many dealerships honestly have no clue that this stuff exists and will sell you the wrong stuff.

When your done changing the MTF, do you drive it around a bit and check the MTF levels again?

 
Rep Power: 274

I don't, but basically the only way to do that is to jack the car up, unscrew and open the filler hole, and see if the fluid is at the line. Fluid expands as it heats a bit, so you'll possibly get a wrong reading. Plus hot gear oil on your finger. Plus a PITA jacking the car back up again... I usually just trust my levelling of the car and the fact that what looks like 1.5-1.7 qts of fluid is no longer in the bottles.

I used 10-30 mobil 1 synthetic, but I think I might just get the honda stuff next time. I dont think it really matters to tell you the truth, they say there are additives that make shifting smoother, but I have never had a problem.

I dont think putting too much in would hurt anything at all in the trans, but I may be wrong. I put a little extra in because of the way my garage is, I just could not get the car perfectly level, the rear ended up higher.

The more you change it the better. If you could I would say change it every three oil changes. If I was doing any kind of racing I would do it that often. I am going to do it every 7 months or so.

well ill add a question to this topic. can u get redline at any parts store? or do you need to order it?

 
Rep Power: 286

Red line suppliers really vary. You can order it, or you can search and see what retailers in your area sell it, and which products they sell.

Generally performance stores carry it. I don't think I've seen at Autozone or anything like that, it's a to much $$$ for the common person to spend on oil.
