914-6 George Vellios oil tank capacity ? Options

[amallagh]

Can anyone tell me what the working oil capacity of a 914-6 would be with a George Vellios cast aluminium oil tank ?
I am assuming the std capacity with the original oil tank is 8-9 US quarts (about 8.5 litres)
Many thanks

Thanks Scotty but does anyone actually know the oil capacity with the Vellios tank ? Your helpful comments about filling technique don't tell me anything I didn't know already.

I need to know what the oil capacity (from fully empty) 'SHOULD' be. Actual volume required.

I took 13 US quarts out of my car when I got it and it was still just below the marked zone on the dip stick when hot. Full volume to the marks on the dip stick would probably have been 14 quarts. This was with draining everything including std engine oil cooler. This volume seemed massive and I don't know if it had the right dip stick (how long should it be ?), was overfilled or under filled. The engine was running very badly anyway and was burning oil very badly at higher revs so I don't have any bench mark. Now the engine has been completely rebuilt at considerable expense and I want to get things right when we start it up in the car again. Comments on the last reply from Scotty seemed to indicate that the oil capacity with the Vellios oil tank is similar to the std system at about 8.5quarts. That would be a mile away from the volume that was originally in my car that I just can't explain. It has been very hard for me to draw any definite conclusions without knowing exactly what the oil capacity SHOULD be with the Vellios tank.
Can anyone help with some definite information ?
