I have an oil-injection 2-stroke Mercury outboard motor that doesn't
need to pre-mix oil with fuel. I was told that the the oil injection
system of Mercury outboard motor is not quite good, and I might be
better off pre-mixing the oil with fuel instead of relying on the oil
injection system. This means I probably need to know how to mix oil
with fuel.

I had mixed oil with fuel for an 2-stroke lawn equipment that I rarely
use. That lawn equipment barely works and may have something to do
with I am not mixing oil/fuel correctly. Therefore, my experience on
mixing oil with fuel is scant, and I am not sure if that is comparable
with doing this for a boat.

My questions a

- How do we mix it? Am I supposed to do this:
(1) Half-fill the portable gas container.
(2) Pour oil into the container.
(3) Fill up the portable gas container.
(4) Shake the container violently.

- How long should I shake the container? Let's say it is a 10-gal
container.

- How big a container should I get to pair with a 44-gal fuel tank in
my boat? Should I get one 10-gal container or should I get four 10-gal
containers? I guess we only need one container; but I am not sure.

- Do we refill the gas container in a gas station in this way with
one 10-gal container:
(1) Ask the gas station attendant to half-fill the 10-gal container.
(New Jersey doesn't allow self-service)
(2) Add oil into the container.
(3) Ask the gas station attendant to fill up the container.
(4) Shake the container violently.
(5) Load the gas container on top of the boat, and pour
the mixture into the hole for gas.
(6) Don't pay the gas station attendant just yet.
Repeat step-1 to step-5 for three more times or until
the fuel tank in the boat is full. Meanwhile, the gas
station attendant is rolling his eyes, and other
customers are waiting not very patiently.
(7) Finally, pay the gas station attendant.

Is this really how we get fuel for our boats in New Jersey
where self-service is not allowed? Do we need to get four
10-gal gas containers to avoid this situation? Do we need
to re-fuel only in off-hour?

Thanks in advance.
