Oil & air

[worktohobby]

Hello,

On my 8v92, including oil in the filter, the magic number was just
over 28 quarts. I used a big plastic bin to dump the old oil in and
the transfered that to gallon jugs.

There should be no sludge. On 2 strokers, what gets past the
compression rings ends up in the airbox and in turn returned to be
cumbusted. So little cumbustion by products ever find there way into
the oil.

You can use the shrader valve in the engine compartment. You can also
try the accessory air port in your road side compartment. On my old
bus, this would air up the accessory items but would not air the
tanks. Sometimes handy. I have not tried it on my 87 though.

Hope this helps,
