Winterizing push-lawn mower

8 years ago

Hi,

I have a Murray (Briggs& Stratton) gas push -lawn mower. As it is getting cold, I have emptied the gas tank. Do I need to change the oil end of the season? This is a new lawn mower, so for the first use I added new oil. If the recommendation is to change the oil end of the season, wouldn't this oil eventually just sit in the cold and become old since it is not used in the winter?

    Yes change the oil , it will have been contaminated with corrosive engine combustion byproducts . These properties usually suspended in the oil can settle out and damage internal engine components . In the future to protect your investment purchase the best premium synthetic oil u can afford . I use 5-30 grade for my geographic location but others prefer 10-30 . I utilize Amsoil @ $8 a quart once a season , Shell Rotella or other high end products are out there on sale which also will protect your engines much better , even when in storage due to superior design factors and additives .Also ensure to add fuel conditioner to your fuel prior to running the engine dry , this will ensure any residual fuel within the carb fuel circuits will not foul your carb . I prefer Startron available @ Walmart .

    I ran the the engine dry without the stabilizer as one of the Briggs & Stratton tech had mentioned best is it run it dry and then next season use 100% gasoline. I did change the oil though.

    hi, running efuel won't hurt anything. the trick is not letting it sit around. i do't like using gas that's been in a can for more than a month. i don't buy more than i can use within a short time so i don't waste alot. if you want to use real gas, google "pure gas" and your area for a list of places that sell ethonal free fuel.

    Use a ounce of startron an your gas is good in storage for up to 2 yrs . Running engine dry alone does not adequately prevent efuel from gumming up fuel circuits in all cases . Do you feel lucky sucker ! lmao .

    At the moment, I changed the oil and ran the mower dry, so there is no gas. In Spring, I will use ethanol-free fuel and change the filter as well. Yes 300ft_anin, there are couple of gas-stations which sell the pure-gas.

    sswwalk1 - After a costly carburetor clean-up last season, I am not going to leave the gas in my mower. Yes I left old gas without a stablizer but this time, I am going to leave it dry and use pure-gas. Hopefully it starts next season with no issues.

    I store mine with SeaFoam treated fuel and don't change the oil until the 1st mow of the spring. Never had an issue with starting or power (still starts on the 1st pull after 3 primes), 14 yr old Toro Recycler. Before the 1st mow in the spring I grease the front wheel shoulder bolts, sharpen the blade, check/clean the spark plug and check/clean/replace the air filter.

    Woody yep Seafoam is a quality product use it occasionally as fuel treatment during the winter . I find. It even better when are added to oil just prior to oil changes , usually a week prior , it really helps reduce sludge and carbon deposits on my various vehicles .
