A number of Yamaha 4-stroke riders commented on the lack of mention of the cost of injection oil and oil loss characteristics of 2-strokes vs. 4-strokes. One Yamaha RX Warrior rider stated, “A 2-stroke takes a quart of injection oil (expensive synthetic stuff now days) about every 90-150 miles. A Yamaha 4-stroke at most will burn 1 quart every 1,000 miles. Even when you factor in oil changes and filters, the cost of operation of an oil injection 2-stroke is much greater, even if the fuel economy is similar.” We agree that this is a valid point.

Another stated, With a 2-stroke, 100% of the oil is consumed, making it a 100% oil loss system. On a 4-stroke, even if you use a quart every 1,000-2,000 miles, the majority of the oil is captured during the oil change. The amount of lubricating oil being placed into the environment is much less. Another valid point.

    As for the 2 stroke vs 4 stroke snowmobile, I own a 2006 4 stroke (I will keep the manufacture to myself for now) and here, where I live in Canada’s Arctic – Nunavut, where the temperature right now is minus 33(without wind chill) it will be a crap shot to see if it will start. The odds are against it. Down right impossible almost. Most locals have 2 strokes and they tell me that a group of people came up here a few years ago to study the Arctic and they came with 4 stroke machines. They say that after a certain temp they have problems starting the machines as the spark timing and carbs get screwed up. I have contacted the dealer I purchased the machine from and I am still waiting for a reply on this matter. Does anyone have any suggestions or comments about this. 4 stroke technology at this point should be no different then that in the auto lines I would think(but who knows, I was wrong once before). This unit is getting spark and fuel. I bought the unit down south in Ontario and had it shipped up here so taking it back to the dealer(or any dealer) is out of the question, if it goes back to Ontario it will not come back to the north.
    Any thoughts
