Let's Get to the Bottom of this Fuel Crisis

It's okay to admit it, we hear it all the time. Equipment users are intimidated to "mix their gasoline".
They don't want to add the wrong mixture and rightly so; trying to operate something with poorly mixed fuel can be futile at best, or worse – it can lead to expensive repairs.

A spring complaint we hear often is: "I've purchased a new piece of eqiupment last year, and this spring when I tried to start it, it's not working!"
Stale gas and improper storage are a few of the most common issues we see with a piece of gas powered equipment that won't fire up but let's talk about fuel.

Stale gas! ..."What does that mean? I just bought it not too long ago" you say.

Well, fuel now-a-days has a higher ethanol content then ever before and according to reports, ethanol can contribute to corrosion and carbon deposits in an engine, and can also dissolve plastic in addition to causing other maintenance problems. Evidence is growing that ethanol-rich fuels can seriously impact equipment performance if not cause major damage.

We're seeing more and more of this damage and that's why we recommend to always try and use premium gasoline in all your gas-powered equipment. Yes, it's more expensive, but it will spare the life of your equipment.

STIHL researchers have caught onto this dilemma in the power equipment industry and they also recommend that fuel should have the highest octane rating possible with a minimum rating of 89. The fuel should contain no more than 10 percent ethanol. Any product containing more than 10 percent ethanol stands the chance of voiding product warranties.

To solve the ethanol problem in STIHL equipment, STIHL developed a new ethanol free fuel mixture called MotoMix for two-stroke and 4-MIX equipment engines.

  • Available in 950mL and 4L containers, the new 1:50 ready-to-use fuel mixture combines premium gasoline with STIHL HP Ultra Oil for lubrication and protection.
  • STIHL Motomix uses gasoline rated with a greater than 95 RON octane rating and greater than 90MON octane rating for excellent combustion efficiency and added power.
  • The fuel mixture has an improved boiling curve for increased responsiveness and acceleration.
  • The enhanced availability of combustible fuel provides for more consistent performance both when starting or after prolonged use.
  • STIHL MotoMix contains no ethanol and it is designed to provide superb protection for the engine by creating a lubricating layer on metal surfaces. The high quality lubrication reduces wear and tear and helps prevent piston seizures caused by the buildup of deposits.
  • It's environmentally conscious - MotoMix’s fuel and oil mixture uses highly biodegradable oil and it is resistant to carbonization helping to reduce oil deposits and residues. With less gunk clogging piston shafts, engine compartment, spark plugs and other engine parts, users of MotoMix fuel will experience less problems with blocked valves, backfiring and inconsistent engine performance.

MotoMix provides better performance and protection for your equipment, while at the same time helping you protect the environment.

Take the guessing, stress and headache out of mixing your fuel. With STIHL MotoMix on hand, you have the perfect pre-mixed fuel and oil combination right at your fingertips.

...and the best news yet? If stored in a cool, well ventilated area, STIHL MotoMix Pre-mixed fuel can last up to 2 years!

Who would benefit from STIHL MotoMix?

Since all STIHL gasoline-powered equipment runs on a 50:1 mixture of gasoline and 2-cycle engine oil, anyone with a piece of gas-powered STIHL equipment can use this product. We recommed STIHL MotoMix as a convenient solution to those that may not use their STIHL eqiupment all the time but want a reliable fuel with no mess.

  • Home and cottage owners
  • Fire Departments
  • Rescue Squads
  • Marinas
  • Seasonal/Mid range users

What if my equipment only takes straight fuel, no mixing required but i'm still having that engine damaging ethanol problem?

You're in luck! STIHL has also created a solution for you! Introducing a product called Moto4 Plus High Performance Alkylate 4-Cycle Fuel. 

What is Moto4Plus?

Moto4Plus is a premium alkylate fuel designed for four cycle engines. At 92 octane, this fuel has no ethanol and is virtually free of harmful additives. Moto4Plus is a great product for customers who operate equipment infrequently, need to store a unit over the winter, or for those customers who prefer to run a high quality fuel.

  • Compared to petroleum based gasoline, Moto4Plus has a clean combustion which protects valves and pistons improving service life.
  • Moto4Plus has a shelf life of 5 years unopened and 2 years once opened.

These STIHL products are handy and designed to be portable for taking to the cottage, with you as you venture out into natures backwoods, and even to just keep in your shed. Enjoy the long shelf life (5 years unopened and 2 years open) and great benefits of going ethanol free!
