Best Gear oil (transmission oil)

[onlyfaith]

there are so many threads about good engine oils but very few on good gear oil and the reason that it should be used in our enviroment.
for the benefit of all pwheelers!
please share your experience:
which gear oil (transmission oil ) do you use and why?
whats the price of your gear oil?
expert opinion from senior members is highly appreciated!

I appologise in advance if a repost!

I think that the type of transmission, car model, and drivetrain combination should also be mentioned, since that will determine the best type of oil to use.

Change intervals would depend on the type of use the vehicle is put to.

sir ,
thanx for the valuable input.

so dear pwheelers please mention your car model, type of transmission and change interval also!

A basic principle that I go by is to prefer full synthetic lubricants if I can find them in the specified specifications.

Corolla, LS430, LX470: Toyota type WS.
Corvette: Redline Syncromax
The manual IS250 and FJ both still on original fluids in the trans still so haven't looked at replacements yet, but willpick a Mobil 1 full synthetic in the specified grades.

I think you need to specify the car and transmission type if I am to attempt an answer.

I was about to make a same thread.
I have a Baleno with about 120k kms on clock.
I think I should change its gear oil as its never been changed before.

I would appreciate the experts recommendations about this.
Should I change it or not ?
If yes, which oil ?
What are the concequences of changing or not ?

Ok my car is Suzuki baleeno, 1999, mileage 125K approx, 1300 cc MT, front wheel drive! i use PSO gear oil bt i am not satisfied with it, gets dark pretty soon!

my second car is JDM corolla 1997, 1500 cc, 100k on odo, AT, front wheel, use ZIC AT brand in it.

my 3rd ride is suzuki mehran 800 cc1995 almost 80000 on odo, MT, use PSO oil in it! not happy at all!

Also i started this thread so that a "dont know how and why person" like me can benefit from experts like you.

I can suggest oils for all three, but they may or may not be available in Pakistan at a reasonable price or from a trusted source.

For the Suzukis, I would suggest the Mobil 1 75W-90 synthetic gear oil, while for the JDM Corolla, Mobil 1 Type 3309 synthetic ATF.

I am sure local experts will be able to help you better.

Auto or manual? Which year?

Auto or manual? Which year?

Manual. Model 2004.

I know there is no link b/w engine oil and gear oil. So using mineral oil in engine and using synthetic oil in gear is no issue ? Am I right ? What will be the life of the oil you recomended(in kms) ? I will be changing it first time after 120k kms, should I change it or still drive with it ?

The engine and trans oils are in separate compartments, so no worries there.

I would suggest the Mobil 1 75W-90 full synthetic in your car, changed every 75,000 km, but immediately if having driven through deep standing water that floods the engine compartment.

1) What is next option if this is not available ?
2) How could I know the viscosity of current oil ? Is that 75W90 also ?

If it is the original fill, it will likely be a straight 90W mineral oil. If Mobil 1 is not available, then look for any 75W-90 oil meeting at least ILSAC GF-4 standards.

Thankyou so much for such immediate help !

One more question !
Using synthetic oil instead of mineral oil for gear is for long drainage period or any other benefit ?
