440 Manual gearbox oil
My 1994 manul 440 has recently developed a slight transmission oil leak. Unfortunately I can’t get it repaired straight away so I thought I’d simply top it up until I can get it fixed.
The question is what with? My Haynes manual suggests ‘Volvo special oil Part No 3343922-5’ and does not list an alternative. My local dealer can supply this oil but they were somewhat shocked to learn the smallest quantity they could order was 3 litres at a cost of £45! I reckon I need about ¼ litre maximum. They did try to find out what it was so I might be able to buy a smaller quantity of a suitable equivalent elsewhere but found Volvo weren’t giving any details away.
It looks and smells like a hypoid EP80 or 90 gear oil but that’s hardly scientific! On the basis any oil is better than no oil , I’m tempted to try a modern synthetic gear oil.
Any comments and advice would be welcomed please.
Many thanks
