Default Mixing gear oil bottles

So, I went to do my lower units the other day and realized that the Suzuki Ecstar oil bottles have that wide mouth on them. The pump I have will not fit that. My thought was to take an old motor oil bottle that might still have a bit left in it, dump out what I could and then put the new gear oil in it to pump into the lower. Is that a bad idea?

just make sure the old bottle is cleaned out and you're good to go.

LABEL the re-purposed bottle. Some day ....about 8 or 9 years down the road.... youíll not give it a second thought. Unless you fail to LABEL the re-purposed bottle.

No need to wash out as a touch of motor oil won't hurt but this guy has the right idea. Make sure you use it all and chuck or clearly label, not real good putting 90 weght gear oil into an engine.

Think I should actually clean it with like mineral spirits or something? I was just going to drain it for an hour or two.

I should have titled this more clearly. I donít have an old gear oil bottle. I was going to use an old motor oil bottle.

I would just drain it, I'd rather have oil residue than mineral spirit residue.

Sorry my bad I edited my post as you had motor oil in your post I read the title but skimmed your post, poor effort on my part!

You can just hold the pump on the Ecstar bottle. Or order the correct pump from online if you're not in a huge hurry to change the fluid. The part number is 990C0-99001. They are usually around $10 online.

Should I be concerned that my lowers didnít take as much oil as the manual states? They should take 1.1 quarts but I didnít even get a full quart into either of them. I let them drain for over an hour and nothing else was coming out.

Did it come out the overflow when you were filling, and were the motors down and roughly level? If yes to both, good to go.

Yep, down and I actually put a level on them to make sure, because, OCD. I left them sitting for about 15 minutes and then pulled the top plug again and it was still coming out. So Iím pretty sure itís full, more concerned that I didnít get all of the old stuff out but I donít know how that would be possible either.

It is hard to get all of the oil out of a LU. I usually tilt them up and drain thin level then down past level. When have taken them apart, there is usually still some oil that comes out. If the oil is similar, I don't usually worry about it as long as it comes out clean (no water or metal chips).
I am not sure if there might be a problem mixing dino oil with a synthetic but I doubt it. I always use a marine grade L/U dino oil so it really doesn't matter. I also would not be that worried if there was a trace of 10W40 there. This is just oil, don't go nuts about it.
