It takes 2 kilograms of oil (Elf 20-50w) - I kid you not check out the manual.
I did an oil change 3 days ago so it's fresh in my mind :laughing: Penrite mineral oil 20-60w I use.(Australian made & rules the world).
It broke down like this , I put in 2 litres - took it for a ride around the block - let it settle added a little more , checked dip stick - took it for another ride around the block let it settle for 10 minutes added a smidge more & presto - PREFECT (just a fraction below the max line).
I guess standards in the old days where a little less rigid than nowadays, so I guess your input is more important
