gearbox oils

[wedgey]

hi everybody

i am going to change my clutch in the not to distant future

my question is the best grade and type of oil to use in my gearbox and diff

if i use a thinner grade would that make the motor not work as hard

and a smoother gear change

i have a 2.8 nissan with the 5 speed gearbox

in my 1971 240z

any help would be good

thank you

You might consider using a good synthetic such as Redline MTL.

Bryan (nwcubman) just put that in his 240Z recently, and I run it in all the rest of my vehicles. (The Z doesn't have a manual transmission... yet.)

Ditto on the Redline.

SWEPCO 201 is what I use. Very popular with the Porsche 911 crowd so if anyone has a steel synchro trans out of a roadster or a comp trans, they would do well to try it.

I cut it 50/50 with ATF for the transmission, makes for a little quicker shift. According to my ex-boss that's what BMW uses in their transmissions from the factory. Use it full strength in the diff, and no LSD additive is needed.
