Ok, so i've read and heard a lot of conflicting, confusing info on the honda mtf. i own a 94 integra and the owner's manual says to use MOTOR OIL (yes, thats right) as manual transmission fluid. a lot of people have said that this is because the manual was written before Honda developed its own MTF.
(if you don't believe me, this is EXACTLY what is says in the 1994 Integra Owner's Manual: "5-speed Manual Transmission: Check the oil level a couple of minutes after shutting off the engine. Make sure the car is on level ground Remove the transmission filer bolt. The oil level should be up to the edge of the bolt hole. Feel inside the bolt hole with your finger. If you do not feel any oil, slowly add oil until it starts to run out of the hole. Reinstall the filler bolt and tighten it securely. only use an APE Service SF or SG grade motor oil with a viscosity of SAE 10W-30 or 10W-40. The transmission should be drained and refilled with new oil every 24 months or 48,000 km (30,000 miles), whichever comes first. Shorten the service interval to every 12 months or 24,000 km (15,000 miles) under severe driving conditions (see page 126).")
That's right, OIL.
I went to the dealership and asked them what to use, and they said they have two MTF formulas, an "old" formula and a "new" formula. the guy at the dealership said the "new" formula was made for honda's 6-speed manual transmissions, and he would recommend the "old" formula for my car. however, i've read so many threads with people ranting and raving how good the "new" formula is.
my mechanic told me that honda's mtf is nothing more then overpriced, repackaged engine oil, and that honda doesn't manufacture its own oils, but gives that to another company to do. he told me, for example, the honda atf is actually produced by mobil 1. he said the reason that people think the honda mtf makes shifting so much better is because your shifting will always feel better after putting new fluid in your transmission, whether it be the engine oil or honda mtf.
so could someone with some expertise please tell me this:
-is it ok to use engine oil as transmission fluid for my car? (after all, this is what acura recommended when the 94's were made)
-whats the deal with the honda mtf? and if i were to use honda mtf, would it be ok to use the "new" formula, or should i stick with the "old" formula?
-what is the best fluid to put in my manual transmission?
