Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

Happy holidays every one! ... bought the toro 1028 OXE back in October, right after the very first early snow storm. Was not able to try it in snow... I added the startron stabilizer And filled up the tank with 93 octane. I tested the new baby, showed off without spinning augers... But now it's a long time unused. My question is: is it okay for the fuel to sit in the carb for such a long time? Thanks!

all you can do is take care of you auto or ope.  Change the oil, oil filter and air filters when required.

Good fuel will help keep injectors clean and maintain a good spray pattern.

All engines will loose power as they get older it's just a matter of how much power they loose and most of that is directly attributed to how the engine was maintained.

Change you oil, oil filter, air filter etc as recomended by the MFG (your owners manual will give you the intervals)
Use good quality gasoline of the correct octane.
Use good quality Oil and filters.
Don't drive a cold engine hard, drive it easy until it warms up.
Don't abuse your equipment.

I have seen dozens of cars with over 200k the still run very well with little loss in performance even with those kinds of miles

I was reading somewhere about using the Startron in fuel will increase its shelf life to 2 years! Is that possible?

just my 2 cents, it says right on the sta-bil bottle that it's only good for 2 years after breaking the seal, so you need to check on how long you've had it.

What Startron actually says on their web-site:

"Gas and diesel fuels break down rapidly which results in lost power and poor performance. Star Tron stabilizes the fuel chemistry for up to two years in gas and in diesel."

Up to two years is not the same as saying it will definitely increase shelf life to two years.

Personal opinion. (worth what it cost you) I use one year as my fuel life limit, stabilizer or not. 

Those that say stabilizer is a waste of money have had much better luck than me. I have cleaned plugged carb jets on lawn mowers, snowblowers, snowmobiles and motorcycles when they were left for the off season without stabilizer added.

CharlesW:

You'll have less trouble with carbs if you store them dry.  Why spend money on an additive of questionable performance when a know method will prevent problems?  Drain the tank, run the carb dry and/or drain the float bowl and you shouldn't have a need for additives.

You could very well be correct.

Or

I could pour a little stabilizer in my fuel can and fuel tanks and I shouldn't need to: "Drain the tank, run the carb dry and/or drain the float bowl".

FWIW, I don't find stabiliozers to be all that expensive. Less than $10 will buy enough Stabil to treat 25 gallons of fuel and about $7 will buy enough Seafoam to treat 16 gallons.

   Sta-bil at least won't prevent gumming which is mainly from evaporation.  Try putting some in a cup and let it sit around for weeks or months and see what happens.  Sta-bil evaporates along with the gas and leaves a pink film.

   What does Sta-bil do for water?  Put some gas treated with Sta-bil in a white cup or class along with some water and see what happen over the weeks and months. 
Shake the container every so often to get the gas to cloud up with water giving Sta-bil more chance to act.  It dosen't do anything to the water.  The water always forms a blob at the bottom every time and over months. 

   As far as changing the molecular structure of gas I've never seen a claim about that on any additive site and for sure not Sta-bil's site.  Lots of claims but nothing about how it works.  If that had some secret sauce they would tout it. 

Hey Trouts,

I can't believe how many participants actually believe in fuel additives. 

It would appear that you and I have conducted enough experiments to know, that in general, they're virtually useless.   I was a sucker for that stuff for years but have since given it up. 

Some people learn and some don't.

I'm not disputing what you guys have found. You have way more experience with it than I do. I can say that I typically put stabilizer in my gas between seasons (but not always, I'm sure), and I have not had trouble the next time I go to start them.

What do you suggest for engines without drains in the carb bowls? Just run them dry? I know people say that a smaller amount of gas will still be left in the bowl, if you do that. I could see, for instance, running them dry, after putting stabilizer in the gas, to help the amount that's left.

Even if stabilizer doesn't do much, I typically don't use it mid-season, when I'm going through gas quickly. So maybe it costs me a few dollars a year. I have no problem paying that for a bit of peace of mind, even if that's perhaps all it gets me I will say that using Chemtool B12 to try and clean some carb parts was somewhat interesting. I was using it straight, and it certainly wasn't just dissolving the junk on the parts I was soaking. So it did make me curious what it's able to do when mixed into gas at a much lower ratio. But I'd already tried to clean some of the junk off the parts. It's also possible that I'd already removed what it would have helped loosen.

I've never seen a carb (excluding diaphram carbs) that didn't have an accessible float bowl.  Even cheap plastic Lawn Boy carbs have a removable float bowl.  If you do come across one, you could just blow a bit of compressed air into the fuel line to the carb.  That should remove pretty much everything in the float bowl.  Go easy on the pressure.  Maybe 10 psi.  Don't want to put too much stress on the components inside the float bowl. 

The point I'm trying to make is that fuel additives have never shown a benefit for me other than the "illusion that they may be working" caused by some desire to think that they are.  

In some instances, an additive might help remove carbon build up from a two cycle engine  piston and/or head.  However, I've never seen enough carbon in a two cycle engine that needed to be cleaned out.  Today's two cycle engines run pretty clean and don't build up much carbon.

Last summer I scored three old Lawn Boy mowers that weren't running.  I took them apart and found the internals to be in great shape and the exhaust ports very clean on the two new ones (early 70s and just a bit of build up on the oldest one a 1965.  So that engine is over 45 years old and you can bet that it burned old fashioned engine oil rather than today's modern two cycle oils.  You can also rest assured that it likely never saw any additives either and it had only a bit of carbon on the exhaust port perimeter.  Hardly enough to effect performance nor to be concerned about. 

We put way too faith and emphasis on products that provide very little tangible reward.  We delude ourselves into believing that they're doing a fine job when in fact, there is no job for them to do.  I've yet to see any additive clean a dirty carb.  Yet we have people making such claims and more all the time.  I'll say this, if they were having carb problems and used an elixir to fix it, chances are the carb would have cleared itself just by passage of gasoline. 

Snake oil will never replace good mechanical practices and regular maintenance despite what the "believers" say.   The sooner one embraces that philosophy, the sooner they will relinquish their dependence on their magic elixir of choice.
