Tranny oil: 70w-80 is this rating for all honda's? Cause from my machanic's manual it say it's the same as the engine oil for 92-98 integra's. Type R wasn't listed, just said use honda recommended oil.
engine oil and gear oil have DIFFERENT "sae" ratings,
Lighter oil can generally be used for gearboxes, but they usually use thicker oil so that it does not burn. I've heard from a honda mechanic that they usually use thinner oil in gear boxes with problems. He told me that generally he uses a fully syntheic oil in all his cars but only uses engine oil in gboxes with problems.
btw they colour gbox oil. I used the penrite gearbox oil and it is a yellow colour.
I have even heard of mixing some auto box oil with manual gbox oil to help with crunching also.
Personally i only use a fully synthetic oil in my gbox. Castrol syntrax or redline gearbox oil.
