    Some brands of motor oil are greenish colored when "new". Maybe the previous oil change used one of those.

    If the old oil looked "clean" (i.e. not dark colored sludge) I wouldn't worry about it.

    I agree w/ AlephZero. I've used very greenish oil and as long as it is clean there's no problem. I don't know what goes in it that makes it greenish, but not to worry.

    Klotz is red, Amzoil is green, Stihl oil is bright green, Echo oil is gold, Husqvarna oil is blue.
    Oh those germans..Stihl says their green oil is 80%biodegradable in 21 days...good marketing ploy..me ... i save my old motor oil until earth day when I have a huge bonfire. Old motor oil is great to start fire for my old race car tires...

    If it is for the lower unit then they usually take gear oil which has a greenish hue (and stinky!). Are you perhaps talking about that or we discussing the engine oil?
