Motor Oil or Gear Oil

[mcbry]

tanong ko lang, ano ba dapat gagamitin for isuzu bighorn manual tranny? if motor oil ano dapat spec? and also if gear oil ano dapat spec? nagpapalit din ba ang mga gas stations ng motor oil for the tranny?

thanks.

wala ka ba manual? kasi motor oil ng 4jg2 i think is 15w-40 at alam ko yun din sa tranny nya.

niwde11, walang owner's manual yung bighorn (3doors) namin. petron trekker 15w-40 gamit namin na engine oil sa 4jg2. so, pwede ito narin ang gagamitin namin na oil for the tranny? thanks.

Sounds right, motor oil 15w40 for manual tranny of Isuzu. Or sae 30.

thanks guys, i'll just use motor oil 15w40 for the tranny and tcase.

any idea if 6 liters of motor oil is enough for both tranny and t-case?

Accdg to manual;
M/T; Transmission MUA model=2.95 liters; AR-5=2.7 liters; Transfer Case=1.45 liters
So i think 5 liters is more than enough.

You can never go wrong with 10-30W oil for your engine, but 45W for your manual tranny, I think thats a little bit too thin for that. Most tranny that I work on usually takes between 75W - 90W Gear Oil. And on the transfer case, its the same with tranny except if you have LSD, then you have to be more specific like JL-4 or JL-5.

yeah, for cars like those use slightly thicker gear oil.
