Gearbox oil, can you mix... same viscosity / different brand

[guysy]

Quick question. I've bought 3x 1L bottles of 'Valoline GL-5 80w90 Gearbox oil to refill my gearbox after its been refurbished.

Then I remembered its 3.1L from dry.

If I get a 500ml bottle of carlube 80w90 just for that 100ml extra it might need will that be fine? Seems stupid to buy another 1L when I only need 10% of the bottle.

Viscosity doesnt matter if its slightly different anyway TBH, but type of oil can, im sure that will be fine though.

Ok well I have 3L of this http://www.eurocarparts.com/ecp/c/Renault_Clio_2.0_2005/p/car-accessories/engine-oils-and-car-fluids/car-tranmission-oils/manual-transmission-fluids/?522770372&0&cc5_868

Euro c p dont seem to have any 80w90 carlube at the moment but Ill pick 500ml up of it when its in stock.

Other than it should be 75w80 you'll be fine.

 

[guysy]

Damn. I'ts 75w80 correct as above, 75w90 thats ok to use as well and cheaper isnt it?

I thought Id bought the ok to use and cheaper 75w90 but seem to have got 80w90. Will this be ok to use or not?

 

[guysy]

If it isnt, Ill have to wait till Euro are doing up to 50% off again and get this: http://www.eurocarparts.com/ecp/p/c...nual-transmission-fluids/?522770402&0&cc5_868

You'll probably struggle to get 3 litres in nevermind 3.1

 

[guysy]

From dry?

 

[DrR]

Opps.

 

[Fred@BTM]

100ml really won't matter

 

[guysy]

And what about the 80w90 Fred?

 

[Fred@BTM]

might be a bit hard to select gears when cold, but will be fine

Drove around in my 1.2 with straight engine oil 8 years ago and I still see the car going around today lol.

 

[guysy]

Lovely. Might sell it on and get 75w90 or 80 but after some research hopefully it will run well.

Might as well put the right stuff in the first time to be honest with you
