Oil for 1100

[dunnie]

I've lost my Haynes book, please can someone advise which gearbox and final drive oil I need and how much for my 98 1100.
Thanks in advance

Any GL5 gearbox oil. I use halfords 80w90. The important thing is whatever you use has to be GL5 grade. Annoyingly to do a gearbox and FD oil change takes just over 1 litre ( so you have to buy two bottles).

Can you use the same oil again in a few years time?

If by "the same oil" you mean the unused oil out of your second bottle, then yes in my opinion of course you can. Personally I wouldn't use oil older than a year or so but I've no idea how long it actually takes to 'go off' in the bottle.

As I change all my 1100's fluids every 3000 miles it's never an issue for me...

Yeah but the next 10 gearbox oil changes you only have to buy one bottle.

How can oil go off ? It's millions of years old before they bottle it anyway.

I use a 80w/90 GL5 for the gearbox and a straight 90w Hypoid for the F/D

That was my thinking also. No doubt the oil manufacturers can come up with some highly technical reason why you should buy new.

A few years!?!
Change your FD oil every time you change engine oil, it costs feck all

Please explain the advantages of that for us oil numpties

What? and get all those new bearings dirty!! madness

Easy, The Final Drive has hypoid gears so I use Hypoid oil




Hypoid gear cut as opposed to the straight cut gears in the gearbox

I just used 80/90W GL5 oil.

It is GL5 which is the important bit as I believe it has a high concentrate of extreme pressure additives.

I think all GL5 is technically a hypoid gear oil and hypoid gear oil is GL5.

Dunno why the make and sell Hypoid gear oil then

[MattW]

Yeah but the next 10 gearbox oil changes you only have to buy one bottle.

Use the nearly full bottle from last time for the initial fill and top up with the new bottle you've just bought.

A few years!?!

Spot on.
The FD only holds 250mm and works its little bit of oil bloody hard.

You can change the gearbox and FD oil for £10 (less if you've got a halfrauds trade card ). It's a no-brainier as far as I can see...

Marketing.
The 80w90 is labelled as 'differential oil' anyway - go figure.
As long as its GL5 it doesn't matter.

I once filled my gearbox with expensive 'extreme use' Castrol Syntrax 75w140 to see if reduced the clunking and general Massey Ferguson qualities of the box (it was like golden syrup).

It made sod all difference so I've gone back to 80w90

Its not marketing, there are differences between gear oil and hypoid gear oil, a bit of home learning with Google as your friend might help

And if your still a non believer just keep on filling your F/D with gearbox oil

main thing is with the gear oil is as long as its got EP on it which means extreme pressure oil personally I use EP80w90 cannot go wrong with that even in gearbox or final drive

I know there are differences but the 80w90 I put in my FD (and gearbox) is labelled as 'differential oil'. Last time I looked, differentials contain hypoid gear sets.
