: mixing 2 stroke oils
08-14-2008, 09:40 AM
I recently bought a boat with a 200hp 1994 Johnson on it.
The guy put West Marine 2 stroke oil in it. I am running this out so I can put something better in it.
Its got a little less than 1/2 of oil in it now. I am going fishing tomorrow and would like to keep the tank topped off.
I have some Amsoil hp injector oil that I use in my sled.
Can I top it off with this? Im not sure if its a good idea mixing regular and syn oil, but I have run a stoke since syn came out LOL
I'd take the can and wait til the stuff in it ran out, myself. Thank god for 4 strokes is my other thought

the problem if it runs out or low then air can get in the line and I dont want that
as far as your comment on the 4 stroke thats well and good but that aint what I have!!!!
Ahhh a remote tank I bet. Yea, I guess I wouldn't mix though.

actually I just looked on the amsoil jug and it says you can mix them, just that it should be minimized. so I will be ok for this one time.

Presuming the low oil horn works you could wait until that point - big waves could change my mind. I have mixed w/o issue but always have mfg oil around, xd100 or xd50. I might even trade you some gallons of xd50 for a gas auger?

that would work Lazy!
gotta dust that auger off. Ice season isnt that far away UGH

How about snagging your wifes turkey baster, and sucking-out the old stuff?

now theres an idea.
Actually I can use my oil change pump from my I/O

Don't mix oil meant for a water-cooled engine with oil meant for an air-cooled engine.
LawnBoy oil isn't good for outboards, and "TCW" oil isn't good for chain saws. Is that Amsoil oil designed to burn clean in an air cooled or water cooled engine?

the amsoll is fine to use. says right on the label optis, e tecs, yammis etc etc
the sled is water cooled

A PM of the tank would be a good idea considering the age. What's a little wasted oil for a man of your wealth? :)

no wealth here I am laid off LOL
and have two boats to boot

Wow. Sorry to hear that Brian.
I may be in the area in 2 weeks for a meeting. I will let you know if so. Cheap lunch on me.

I have changed brands on many 2-strokes. A couple outboards, several sleds and lawn equipment. I always run the oil down as far as I'm comfortable then start filling with new oil. Never an issue. They all lubricate. BTW in most instances I have changed from dyno oil to Amsoil.

One of the requirements for TCW3 rated oil is that it will mix with all other TCW3 oils. I know Amzoil isn't TCW3 certified but it does say it meets or exceeds all TCW3 standards.

I run a couple big e-tech and 2 optis, I mix oil all the time between otimax oil and xd50 and they have all run just fine for the past 2 years.

So you are using xd50 in your etech & not the xd100?

Now that you are cooled down:sorry:, when I had snowmobiles I use to run them down fairly low in the tank or take a turkey baster:stick:, and suck out as much as I could, then top it off with Amsoil.
No issues here.
I went from regular oil to synthetic in my snowmobile and because they don't mix I came out the next day and had separated and all the synthetic was on the bottom and the regular oil was on top. I just drained it all out and put the synthetic in . I don't know if there would have been a problem but this it what I did. I called several dealers on this topic and got several different opinions.

I have mixed oil several times and had no issues. For some reason that seems to be the thing I have to buy while on the road with several full gallons sitting on the bench at home....
Brian, how do you like your Grady?
