honda mtf is a good option or torco mtf ( either conventional of fully syn )

the mobil might be way to thick.

Do not use Honda MTF.

What country do you live in?

Just curious, why not Honda MTF?

many people say the new formula is too thin. while true. im sure it still provides more than sufficient additives to protect the gears.

Is it the best option, probably not. Torco that is focused more on performance might be a better option.

Nothing out there works better than Honda mtf.

You are in a very small crowd with that opinion. Do you rebuild them on a regular basis?

holmesnmanny

Not on a regular basis no, but I've done enough. I've used a bunch of differnt fluids and honda seems to provide the best shifts and quietest sounding trannies.

You haven't tried Torco have you?

Too thin, lacks good EP additives. 10w-30 is a better option.

I'm guessing it will be easier for the OP to get hold of Motul than Torco.

holmesnmanny

Honestly no.

Try it, you'll never go back to Honda MTF.

I have both MTF and RTF in stock ready to ship.

Bony123

Will 10w-30 engine oil be ok for using in type r gear box.we have caltex both mineral and synthetic gear oil here

I'd go with Redline over 10W30 but you can use either.

Bony123

Ok 😃

Please remember that Honda calls for 10W-30 oil to be used as a temp replacement for Honda MTF. Believe me, Honda MTF is good stuff. Do NOT use a 75W-90. I mean just look at the numbers for a moment. The viscosity is way off. I for one tried to use that GM Synchromesh stuff years ago to try and "cure" grinds. It does for a little because the viscosity is wrong, and in a few months, you'll need new internal bearings. Everyone who says "I tried X fluid and it was awesome", go ask them if they can report back in 2 years and see if the incorrect fluid thickness made anything worse.

Just so you know, gear oil weights are rated dofferent than motor oil weights. Viscocity wise a 75w-90 gear oil has the viscocity of 10w-40 motor oil



The reason for the numbers discrepancy is because SAE wanted to make sure people wouldnt accudentally grab a 10w-40 gear oil and mistake it for engine oil.

Last thing I tried was Lucas 20w-50 high zinc racing oil in my em1 trans and had no issues...
