Unified Marine Seasense (50091443) Oil Mixing Bottle

I tested and the measurements and 50:1 oil chart were accurate. I tested two other brands that were not. Includes the cap in 2024. Great product!

I have premixed almost all of my old outboards over the years. Sea Sense makes the process fool proof. Just select the column with the fuel to oil ratio recommended by your motor manufacturer, and the number of gallons of fuel added. Fill to the correct line with good quality 2 stroke oil and add to tank.

Super easy to use without having to measure out ounces to mix with fuel. Simple scale to follow, look at the mix ratio you need, add oil to the gallons of fuel used and you're done. That easy. I go through about three 5 gallon containers of mixed fuel per week and this little gadget makes life that much easier. I use 100:1 mix with Amsoil Saber 2 stroke oil for all of my machines and this has the required scale.

Nice bottle for mixing my outboard 2 cycle 50:1 oil. I will be able to get a consistent mix so I don't foul my spark plugs.Bottle was delivered with no cap, picture shows a cap on the bottle and description doesn't say it doesn't come without cap.I was going going to buy another one after I checked out the quality of the first one, that's not going to happen now.The cap would be nice to keep it ready for the next fill up.Buyer beware.

If you're looking for one of these buy this one.

Very useful

Easy to use. Bottle has measurements for different ratios clearly marked.

I already had one of these and it proved to be indispensable when mixing oil for different oil to gas ratios especially 50 to 1 and 100 to 1. I bought this for my neighbor. The great advantage is that you can mix 1 gallon of gas instead of mixing 2, 3, etc. with oil. Therefore, you can limited amounts of gas and oil mixed to eliminate varnishing.
