Buy from Fuchs/Gulf/Motul etc and you will get an extremely good oil equal to but most likely superior to the volvo oil.

Disagree with you again Andy, you say so much without backing up your facts .
Volvo gearbox oil has always been the very highest synthetic quality , that is why it is still going strong in volvo gearboxes after 25 years or more with the corresponding mileage .

What you say is no doubt true about the average car out there parked in every side road but volvo do things differently . How much volvo experience do you have anyway? You get what you pay for with volvo like most things in Life 👍
