Ethanol and Your Warranty

With spring coming or at least many hope it is after one of the worst winters in recent history, now would be a good time to start thinking of green grass and some beautiful roses in the flower bed.

Before you start those gardening projects, though, you need to ask one critical question: Is your equipment ready? Follow these tips that some forget until the mower won’t start and a few that many do not know about.

1) Sharpen your blade

2) Change the oil on 4 cycle tools

3) Replace the air and fuel filters and invest in a new spark plug

Follow these simple tips – you’ll be very glad you did.




All of the 2 cycle companies on the face of the earth are fighting warranty problems and many are refusing to cover what most believe are problems with their machines.  Let me Explain

Our beloved gas companies have convinced the government we need ethanol in our gasoline and I am not here to debate that issue. What is done is done.  And what is done is a gummed up fuel system.  In a single engine plane that could spell big trouble. Maybe that is why the FAA will not let them put ethanol or alcohol based fuel in aircraft. But putting ethanol fuel into the fuel for tools does not carry the same risk; it does, however, carry a potentially big cost.

The  effects that ethanol is having on all the rubber parts in your lawn equipment as well as any tool where you mix gas in the oil or that has a carburetor can be an expensive problem!!   BEWARE

Ethanol produces moisture, not a good thing to have in your gasoline. Plus, it has been shown to  cause many of the rubber parts to swell, deteriorate and decay, which ruptures carburetor diaphragms, splitting fuel lines and causing that cute little primer bulb you push to spew fuel in your face.

Here are a few tips from Echo Usa one of the premium Outdoor Power Companies and more can be found on their website.

Fuel stored improperly can result in your warranty claim being denied. Ethanol in it’s pure form is a great degreaser and works the same way in tools that you mix gas and oil in by preventing the oil from doing it’s job which is to lubricate the working parts of your 2 cycle equipment. All of the major companies have changed their oil and are offering a premium gas/oil mix such as the Echo Red Armor.  A semi synthetic mix that counters the effect of ethanol in 2 and 4 cycle units.

Use only recommended fuel, 89 octane or above, and never use e15 or gasoline with a 15% ethanol content. Otherwise, consider the premixed fuel in a can with no ethanol.

Only buy enough fuel for 30 days, and make sure it is a quality fuel from a high volume station to prevent getting stale fuel

Add a name brand fuel stabilizer and mix it at the pump. Note: fuel stabilizers are only effective when mixed with fresh fuel.

Use a self venting fuel container preferably with a no spill spout. High humidity adds to the moisture problem since blended fuel attracts moisture as soon as it’s exposed to air.

Of course Echo wants you to use their oil but at the very least use a name brand gas mix that has a fuel stabilizer similar to  the Echo mix.

Shake the can well before every use for at least 30 seconds and if there is fuel in a tool, shake it to mix the fuel and suspend any moisture in the fuel.

Store fuel in a cool dry place, That is a good one. How many have an air conditioned garage  or tool shed? Well maybe not a problem in Alaska, but then ……..

Above all, and most important if you are not going to use the tool in the next 14 days, drain the gas/oil mix back into your fuel container and start the tool and run it until it dies. This gets all the fuel out of the fuel lines and off the carburetor diaphragm.
