Winterize - drain tank vs sta-bil

I have a ride on mower and I want to to it away for winter. I'm so confused and read many sites, is it better to drain my tank or add fuel with stablizer.

if better to use sta-bil how do I do it? Fill my tank 100% full?

IMHO:
No need to be confused, running it dry sounds best, however it never really runs completely dry and what remains evaporates leaving varnish which after doing it for a few years starts to create problems, so then maybe its better to leave it full of fuel which will fix the previous problem, however that would be great if the fuel was fresh which is never the case, its the end of the season and the fuel that gets added to fill the tank is the leftover from the mowing season which is already old. I say leave it full of treated fuel then drain it at the start of the next season and fill it with fresh fuel. Have a good one. Geo

I always run my small engines dry but I do add some stabil to the last tank of gas.

I treat my gas with Sea Foam. It has worked well for me as a cleaner and a stabilizer.

I've done both. I find that at the end of season top off the tank add a fuel stabilizer and hope for the best. As Goegrubb says you will always have some residue left be dry or full. I prefer full only because I think it will stay in a liquid suspension longer and be less likely to gum up. BTW...I've never had a starting problem the following spring.

if I leave it dry, should I use a air compressor to blow out the fuel lines?

I never do, I figure the stabil added to the last tank will keep any of the gas from turning to varnish/sludge.

No. Better to break the bank on a small bottle of stabilizer (it keeps from year to year) Add a little to the final run of gas and just run the engine until it stops. Tuck it to bed for the winter.

If I poured too much sta-bil on accident would that do
any harm?

No! It says right on the bottle that too much will not do any harm.

The best thing to do is to treat it and then even though you put it up for the winter, crank it once in a while. Small amounts of gas go bad faster than large amounts. The gas in your carb can go bad before the gas in your tank, depending on conditions. If you crank it up once in a while, you keep the battery charged and burn out what is in the carb, allowing new to enter from the tank.

Thanks cheese you made me think of 3 questions

1. I plan on having my ride on mower in the garage, can I leave the battery intact without doing anything?

2. Is it ok to squirt wd40 in the spark plug hole? I know they mention oil.

3. How do I crank my engine after I lube my spark plug shaft.

You can spray wd40 in there but it's not necessary or really even beneficial. You can leave the battery in it except in really brutal conditions.

I've never ever shot oil down the cylinder on any engine that was just being put up for a season. The only time I've ever put oil down a cylinder is when trying to start up up an engine that hasn't been run for years.

Nuts! The only thing I forgot to do before the snow fell.

Winterize

I have ran all my gas powered equipment dry the past 20 years as well as performing winterization maintenance for storage. I do use an enzyme stabilizer additive to gas during operation. My 20 year old MTD rider and other outdoor equipment have served me well so far baring mechanical issues other than fuel problems.

Yes, it will lose charge slowly over time. I battery maintainer connected to it will keep it up. It may not lose enough charge over winter to matter, depending on the condition of the battery and how it is stored.
