How do you guys mix Gas

[MotorMan101]

I have just gotten a boat with a 1986 Johnson 110hp engine that runs 50/1 fuel ...I don't have a marina to fill up at ...can I just pore oil in the tank than gas...should I pre mix it in gas cans? What do you guys do?

Yes, pour the oil in the tank then fill the tank, guessing it's a 6 gallon tank. Then give it a little shake to mix.

Boat actually has a 20gal in built tank in its hull with like a car fill port on back of transom.

I use one of these mix measuring containers.

For portable tanks, I dispense the gas into the tank, read the pump for the gallons, then pour the correct amount of oil into the mixer. Then that gets poured into the tank. A couple shakes as I load the tank back into the truck and it's good.

For a non-portable tank, I'd use a similar method. Put the gas in, measure the oil, then pour it into the tank. Then the road trip to the water will mix the fuel/oil for me.

Cool, I think all get one of those measuring things

Depending on where you are, be sure it jives with the gal/ltr readout on the gas pump..... May be confusing if the pump and mix jug don't match.

Since you are transporting the Fuel in Jerry Cans, You have a chance to mix it properly. Add a gallon or 2 gas to the Can, add the correct amount of oil for a full can, Put the Cap on the Can, shake it vigorously a few times, fill it to 3/4s full, and shake it again, sloshing the gas-oil around, then top up. Tipping a tank on its side really does F all, as the tank just rotates around the fluid inside. Pouring the fuel out of the cans into the Fuel tanks will complete the mixing. Never fill the Tank, and then add the Oil. Most of the oil will just settle to the bottom, and at first the Engine will get way too much oil, and as the tank empties, it will get less oil, possibly almost oil less. Unless a container/tank is almost empty, very little agitation of the Gas-Oil occurs while in transit, the oil will simply remain at the bottom of the tank.

Depends on how you drive. Vroooommm... screeeech... vrooooommm....screeeech...bumpity, bumpity... vrooomm!!!

I've always just put the oil in at the pump after filling. The trip to the lake and launch mixes it up.

Here's a vote for mixing it up 5-6 gallons at a time, before putting it in the boat.

Unlike the past when high viscosity motor oils where used, todays two stroke oils are designed with a low viscosity to allow the oil to be mixed with gasoline quite easily.

One only needs to combine the two products with light agitation to mix the two

My boat is injected, but when mixing fuel for the farm, I simply put the oil in the can then add the right amount of fuel. The agar ion of the fuel going into the can is throughly mix the contents

If you’re concerned about it mixing completely in the tank, just mix whatever quantity of oil you need with a quart or two of gas, then pour that mix in the larger tank and gas up.

I learned to read my gas gage, tested it by addung 5 gallons at a time to an empty tank and marking it accordingly. Now I can look at my gage and know how much gas I need within 5 gallons. Who cares if my gas tank is filled to the tippy top !! I add oil for what gas I will be putting in, then when adding that gas, I know it is getting mixed in properly! Do yourself a little experiment....take a small 2 gallon gas can with 2 gallons of fuel in it, pour in your 5 ounces or whatever oil and let it sit.....come back in an hour and see how much oil is still sitting on the bottom unmixed....then you can decide if you want to add oil without thoroughly mixing it in !!

Why are you shouting?

 

[JimS123]

Why are you shouting

He was not shouting. He was emphasizing what was actually common knowledge for those that read boat books and such..

TCW3 mixes instantly. calibrate your gas gauge so you know how much gas you will be adding. Calculate (math) how much oil you need. Put the oil in. Add the gas.

We are not adding 30 w oil like we did in the 1950's.

Actually I dont know what happened, was typing away and suddenly became bold print!! Cant turn it off because I dont know how it was turned on. Sorry for any inconvience, just an old boater trying to survive in todays computor world !!

Bold or not. You simply weren't respected. You said everything right. The bold was no reason to comment on.

Ah, okay then. No worries.

When I saw a lot of bold text followed by multiple exclamation points, it looked like shouting to me. And I'm an old guy who has been on the internet since before the World Wide Web even existed.

That's a bit much, I think. But whatever. I take no offense.

If you always want a full tank , it makes sense to fill the gas first , so you know the exact amount of gas you put in, use that number to mix the exact amount of oil you need.
