I know it's been asked a million times, but the search feature is showing me no love.

IIRC, I just put a gallon of oil in my 919 Blade, but it's been a while (never drove it much over the summer; too hot here in TX). With the new track day coming up, I want to put in the proper amount. What is the recomended amount? I remember it needed to be over filled but don't remember by how many quart(s).

--Thanks, Chris

The manual says:

Oil Change: 3.5 litres/3.7 qt
With filter change: 3.6/3.8
After rebuild: 4.4/4.7

HTH

Not sure you want to be overfilling too much, you may cause more problems than you prevent (slipping clutch for one).

Yep I wouldnt overfill too much, to the top of the sight glass (if its a 919) with the engine stopped always worked fine for me, or to the top of the dipstick if its an 893.

To the top of the sight glass 'tis. Many thanks gents.
