Snowblower Maintenance-Oil is a simple maintenance procedure that should not be overlooked. If you have a single stage 2 cycle blower you will need to consult your owners’ manual to find out what the gas to oil ratio should be for your particular model.
The ratio is important and you need to be accurate when measuring to get what is required, if you don’t put enough oil in then the mix is too lean, the motor will seize up and the snow blower is ruined.
On the other hand putting too much oil in the mixture and the ratio becomes too rich, the blower will run but blows blue smoke eventually runs rough and quits due to the excess build up of unburned oil residue that builds up inside the engine and exhaust.
I also recommend that you use premium grade gasoline in your mixture because the better the grade the higher the octane, the more power you get when the fuel is burned which in turn means the more power your blower will have to throw snow. (you need all you can get with a smaller less powerful 2 stoke blowers)
If you have the dual stage 4 cycle snowblower then the oil and gas are in 2 separate compartments. One is the oil which is in the bottom of the oil pan (the gas engine) the fuel goes in the gas tank. Oil is added and measured by opening and checking the oil dipstick.
To know if you have enough oil in the blower make sure the engine is off and cool to the touch, put the snowblower on level ground to ensure you get an accurate reading. Loosen the dipstick, turn it and pull it out . Wipe off excess oil and put it back into the hole, allow it to drop to the bottom and turn it to close the cap. Undue the dipstick again and take a reading.
If oil is black it needs to be changed, if it is clear like above picture then oil is good a may just need to be topped up if below add level. Most snow blowers use a 5w-30 grade of oil.
When changing the oil on a 4 cycle dual stage snowblower, the machine should be run for a few minutes to warm up the oil which will thin out the oil making it flow out much more easily and completely.
Draining the oil, out of your 4 cycle blower is just matter of finding the oil drain nut (pictured above) a vice grip in one hand holding the oil drain pipe still and a ratchet drive with the proper sized socket. Turn the socket and the drain cap nut will unthread and loosen. (shown in below picture)
Don’t take it all the way off or the oil will spill out all over the place, making a huge mess on the ground. Make sure that below the drain plug that you have an oil collection container and that it is centred below the drain hole.
Now undue to cap nut all the way off and set nut aside. Oil should be flowing out, allow it to drain collection container. When flow slows down to a trickle tip blower backwards towards the ground and more oil should flow out.
When flow again slows to a trickle push snow lower back upright for a second then push it back down flow should increase again for a second. Repeat this procedure a few times until all oil has drained out.
After oil is completely drained out return oil cap nut onto the end of oil drain pipe and tighten snugly. Failure to sufficiently tighten the cap nut will allow it to vibrate free and any new oil added to engine will flow out. If enough oil is lost before the problem is noticed then engine may run dry and engine will seize up rendering it useless and you are out of a snowblower.
Make sure to dispose of any used oil in an eco-friendly manner. Take the oil to a local hazardous waste facility for proper disposal instead of just putting it out with your household garbage.
Fill the blower with the appropriate amount of oil for your snowblower (in most cases the amount .6 of a litre) Please consult your manual for the exact amount. In most cases the oil thickness should be a 5w-30.
I hope this helps for your Snowblower Maintenance-Oil
