Saw Juice
Pro Saws’ “Juice” line of fuels are proprietary blends that contain no ethanol. The fuels are very stable, medium octane designs, optimized for use in modern high performance hand held power equipment.
The octane, stabilizing additives and reed vapor pressures of the fuels are tailored for use high performance engines in commercial applications where high loads and heat tolerance are requirements.
The additive package stabilizes the fuel to allow for long storage intervals without adverse affects to sensitive carburetor components.
The fuels is available pre-mixed 50:1, as well as a non premixed 4 cycle fuel.
These fuels are capable of supporting performance tuned saws as well as OEM hand held equipment.
Pro Saws is so confident in our fuels that warranties of all Pro Saws refurbish services are doubled when Saw Juice is used.
FAQ’s
Why not just use “pump gas” or “street fuel” ?
1st Modern automotive grade “pump gas” fuel is a blend of ethanol and gasoline. This blend is very inconsistent, and is detrimental to the diaphragm’s and metals used in hand held power equipment carburetors.
The damaged caused to carburetors by ethanol is manifest as a lean condition when the diaphragm begins to deteriorate and “bag” resulting in reduced pumping performance that cannot keep up with the demands of the equipment. As this occurs, the fuel mixture leans out until it reaches the point of degradation that the engine no longer performs acceptably or in the worst cases, seizes due to an overly lean condition. Our fuels do not attack the sensitive carburetor parts and due to the additive package can extend the equipments life by years.
2nd, Reed vapor pressures vary in “pump gas” dependent on geographic location and time of year. These variations can cause two main issues. When the vaporization point of the fuel is low temperature wise, as is the case with winter blend fuels, the equipment can vapor lock due to the high temperatures air cooled engines reach in use. Conversely if the fuel is a low reed vaporization blend, as is the case in summer blend fuels, the equipment can be hard to start in mid to low temperature situations. Having the proper reed vaporization point, that is optimized for use in high performance hand held air cooled equipment is critical.
3rd, Stabilization packages in “pump gas” vary by brand, region and fuel grade. For the pumper type carburetors used on hand held equipment, having a stable fuel is critical to maintain proper air fuel ratio adjustments since these are hard set by adjustment screws and not adjustable automatically with the exception of a very few high priced machines. Our additives and fuel is designed to run in diaphragm type carburetors, not damage the sensitive components these type of fuel systems contain and is extremely consistent.
4th, all hand held power equipment OEM’s are under strict regulations of the EPA and in CA CARB to certify their equipment meets the current emissions regulations. They are required to do this using what is known in the industry as EPA fuel. This fuel contains no ethanol, so when they test their newly built equipment, as is done with every single piece of hand held equipment built by any OEM before it leaves their factory. The carburetors are set to run within the EPA mandated emission restrictions on non ethanol fuel. The equipment then has to be able to be run on “street” fuel that has an ethanol content up to and including 10%. This is the reason the more advanced and expensive pieces of equipment that use electronics to tune the air fuel perform best. However, even these engines benefit greatly from running non ethanol fuels due to the higher energy density content of non ethanol fuel and the fact that even these fuel systems degrade due to the ethanol. The OEM’s are more prone to err on the side of being “lean” in their settings than on the “rich” side due to this EPA & CARB testing and the regulations that impose heavy fines if their equipment is found to not meet the requirements. I short, it is less expensive for the OEM’s to err on the side of an engine failure than to risk being outside of the emissions regulations on a piece of equipment. This is why the lean seizure and failure rate is higher in modern equipment than ever.
In summary Saw Juice’s advantages are:
Stable fuel- Engines perform better due to the had set mechanical carburetor settings remaining within the specs required by the engine for a given fuel
Proper Reed Vapor Pressure-Engines start easier and do not vapor lock in high heat/ load conditions.
Non Ethanol- Does not contain ethanol that attacks the sensitive components of a pumper style carburetor and attracts water with results in fuel contamination that adds to carburetor damage
Proper Octane Rating- Engines do not detonate which causes piston and ring landing failures.
Long shelf life- Fuel does not deteriorate easily thus it remains usable for much longer periods of time and does not “gum up” carburetor as “Street Fuels” do.
Tunes available with a refurbish.
When saws are refurbished, the type fuel the equipment will be running on is of utmost importance. This is to assure the units fuel system settings are optimized for the actually fuel the unit will be run on in the field.
Any of the off the shelf fuels from Stihl, Husqvarna, Echo, True Fuel, Tool Fuel, and of course our Saw Juice as well as for street fuels can be tuned to. When tuning for “street fuel” we require the end user to provide us with the measured alcohol content of the fuel from whatever source they purchase from. This is accomplished using an Alcohol measuring tool that mixes out the ethanol into a known amount of water and then based on the increased level of water determines the content of alcohol. By doing so, we can correctly set the air fuel ratio on their saw using the same alcohol content fuel.
This enables us to warranty the refurbish and assures that even with ethanol in the fuel the best possible setup is achieved. It should be noted, that even though the saw will perform properly, and in most cases much better than when purchased new, this tune will degrade with use from the ethanol just as it does with any new saw. For this reason, we HIGHLY recommend the end user use a fuel designed for use in air cooled hand held equipment that does not contain ethanol.
