h22 manual transmission fluid???
i did a search, but the info was all over the place. i'm going to replace the manual tranny fluid in my h22. the manual specifies a 10w30 or 10w40 SF or SG oil. I'm going to use a synthetic oil and am wondering what the SF and SG grades stand for. Can i use an oil that is 10w30 if it has a different API service grade (ie. SJ,etc).. any help is much appreciated. Also which oils are you guys using that meet these requirements?? thanks.

Those ratings get updated every couple years. SH is newer than SG but it satisfies SG & earlier. SJ is newer yet.
But meanwhile Honda came out with their MTF which everybody says is even better yet. I'd use Honda MTF.

No, that's not what I said...
I don't think Honda MTF is synthetic. But it really doesn't say anything on the bottle. Synchros are like little clutches. They don't work real well if the oil is 'too slippery'. I bet your owner's manual doesn't say 'synthetic', either.

no the service manual doesn't specify conventional or synthetic... it says
" Use only SAE 10 W - 30 or 10 W 40, API service SF or SG grade."
wouldn't synthetic lubricate the gears better just as it would for the engine?? would synthetic contribute to syncro wear??

Re: (littledan)
Unlike the engine, the tranny has mostly (all?) ball or roller bearings. Gears are lubricated OK by petro oil. Synthetic's big advantage is long life at the higher temperatures that you get in the engine.
Maybe it doesn't contribute to synchro wear exactly, but the synchro is like a little clutch. When you try to shift you're pressing a couple cone-shaped parts together. One is already spinning and it has to make the other one match it's speed. If the surfaces that 'touch' are too slippery, then the synchro blocks you out of gear for a little bit longer while it tries to spin the gear at matching speed. If you muscle it into gear before it's had time to match it's own revs, it grinds.
I think you'll be happier with your transmission with Honda MTF.
