I got hold of a sanli 350 lawn mower 4 stroke the people gave me a bottle of 2 stroke oil with the mower is this the right oil to use

The choke is not shutting off or u must do it. Look at the controls

If its a two stroke mower it meeds 2 stroke gas. Fairly cheap for little oil bottle and a gallon of gas. Most two cycles use a 50:1 ratio.

Hi , There's two different types of mower oil, There's the oil for the sump (4 stroke mowers ONLY) Ask at the local lawn mower repair store for the oil type and the 2 stroke grade, it's just two stroke oil you add to the gas (2 stroke mowers ONLY) If you own a 2 stroke mower then yes you actually add the oil to the gas before you put it in the gas tank (25 to 1 ratio) but If you own a 4 stroke mower then NO you DON'T put the oil in the gas tank. There is (two) capes, 1 for the gas and the 2nd cap is there somewhere for the oil.... Have a look at the link below... CHEERS..

Well, if it has an oil drain plug and/or a fill plug for oil, It's a 4 stroke. If it has an odd shaped muffler/resonator, it's a 2 stroke.

does the engine take oil? if it does then it is a 4 stroke and does not require mixed gas. if it doesn't have its own oil then it is a 2 stroke and requires mixed

It is most likely oil. Probably passing past the rings on the piston. I use 2 stroke oil in all my mowers / small motors whether they are 2 stroke or 4 stroke (based on advice from a small motor repairer) since the 2 stroke oil helps lubricate the bore and even though there is some minimal smoke usually on start-up. Depending on how bad the smoke is you can try a heavier grade oil and I would recommend using a 25:1 2 stroke mix if you want to extend the life of your small motors.

DO NOT USE MOTOR OIL!!!

There is a special 2-stroke engine oil mix that you can purchase at various stores that have outdoor equipment or you can also find mix at Walmart. There are instructions for proper mixing on the bottle.

Remember not to put 2-stroke mixed fuel in your lawn mower unless it is also 2-stroke (rare). And the converse is also true, do not put your 4-stroke lawn mower fuel in your 2-stroke weed eater.

If this is really helpful, please rate.

You want 2 stroke oil, if it uses premix. You can buy little bottles of two stroke oil that are the exact amount you need for a a gallon of gas, or you can buy bottles with built in measurers to measure for whatever amount of gas. I usually use a 32:1 or 40:1 ratio on my equipment. You will find the two stroke oil in the lawn and garden section, automotive section, and in the marine section of most super stores (i.e. Walmart)
