How To Salvage Accidentally Adding Oil To The Fuel Tank Of A Snow Blower

After all is said and done, we are all human. That means that mistakes will be made. If one of those mistakes you have made is accidentally pouring oil into your snow blower’s fuel tank, don’t fret. The mistake can be remedied.


First, what happens if oil gets into a fuel tank of a snow blower? If the tank is entirely full of oil, then the snow blower won’t start. If the oil is only a portion of the fuel already in the tank, the snow blower will start, but the four-cycle engine will run rough and release a lot of smoke.


Such an occurrence won’t damage the snow blower engine if you drain the oil out and replace it with gas. If you don’t notice the mistake and you start the engine, then it’s possible that the oil will get into the fuel line and the primer pump.


Ridding The Oil From The Fuel Tank


You can clean out the mess yourself or you can take the snow blower to Small Engine Express for service and repair. If you follow the instructions below, but you still encounter problems, then take the snow blower to Small Engine Express to be fixed because complex work may have to be performed.


The process of fixing the problem begins with the draining of the contaminated fuel. If possible, remove the gas tank from the snow blower and dump the oil or contaminated fuel out into a container. Be aware that there may be oil still remaining in the tank. To clear the tank of any residue of oil, add a little bit of clean fuel, swirl it around and dump it. To further clean out the tank, mix dish washing liquid that includes a degreaser in warm water. Pour it into the tank and swish it around to remove any oil that may be clinging to the sides of the tank. Make sure to thoroughly dry the tank with a can of compressed air.


If you can’t remove the tank, tip the snow blower on its side and let the contents flow out of the tank. Be sure not to tilt the snow blower for too long, or oil could flow out of the crankcase and possibly result in lubrication problems at times.


Add just enough fuel to get the snow blower started and let it run a few moments.


Next, remove the air cleaner and add some fresh gasoline directly to the carburetor, then start the blower.


If you have tried to start the blower before draining the fuel tank, then it’s possible that the contaminated fuel has gotten into the fuel lines and carburetor. In this case, start with draining the contaminated fuel as described.


Next, take the fuel system apart, drain it, and rinse as many parts as possible with water, then clean out the primer and carburetor. Cleaning the carburetor is essential because if you don’t, oil can gum it up causing the fuel-air mixture to be off, making the blower inoperable and possibly requiring a disassembly of the unit for further cleaning.


Once the fuel system and carburetor have been cleaned, you need to remove and clean the spark plug. Pull out the plug and clean it with a damp cloth. Be sure to also clean the hole for the plug. Once cleaned, replace the spark plug.


Refill the tank with clean fuel, prep the carburetor, and then start the engine.
