Jay,
DISCLAIMER: I am new to IDA and am not here to insult anyones intellegence, only offer my .02 cents. I do like to put basic info out so everyone knows what I am thinking.
I do not protest to be a know it all either, so feel free to set me straight if I have something abckwrads…
0W-40 is a multi viscosity weight oil. It is made to be like a 0 weight in the cold (thin) and a 40 weight (thick) in the heat. 5 is thicker than 0 and 10 is thicker than 5.
30 is thinner than 40, etc.
Different equipment use different viscosity “ranges” to meet a range of needs. 0W-40 is a wide range oil, giving you a thin oil for cold starting if you use your 700 in the winter and 40 for those hot, summer days when you are working that machine hard – keeping the level of oil protection up.
Heat kills petroleum oil. Synthetics are made to withstand a higher temp load than petroleum oils. One of the first things to go when oil gets hot is the “bands” that hold or make the multi viscosity in oil. The heat breaks those bands and you are left with an oil that is a single viscosity weight, typically on the high end of the range (30-40).
I can tell you that the Klotz ATV oil is formulated different than a car 10w-40 because of the fiber clutches that are used in some ATV’s. The ATV oil does not have some additives in it that would harm those clutches, ultimately shortening the life of them. (don’t view this as a commercial for Klotz, only that I can only speak for that oil because that is what I know for sure – I presume the other ATV specific oils are formulated the same)
You can probably vary from the viscosity range oil that you use, like going to a 10W-40 which might be more readily available to you and you might be able to shop by price having more options that way.
With that said, I will agree that even if you spent 12.00 a quart on oil, for the amount you use in the 700 per year, it is a drop in the preverbial bucket. Don’t go cheap on your motor with .99 cent oil.
