Need chain saw information regarding oil, for example,can I use straight 30wt for bar and gas mix or do I need
Question:any special oil. Also, my new chain saw says 50:1 mix, my older equipment us more like a 16:1. how can there be so much difference between old and new equipment. Why can't I use drain oil for the bar oil? What is this vegtabable oil bar oil?? is that for real or some kind of joke?? Why the hell would anyone want anything but regular petrolium oil?
Answers:
Things change. The reasons for not using drain oil are,
1. Drain oil is not the right viscosity. It will flow through the passages much quicker and run out before you run out of gasoline.
2 Drain oil has waste products in it that will corrode your saw passages.
3. It will be thrown off the blade and make a mess of what ever you are working on.
4. It will smoke on a hot blade and leave black tar when it evaporates. When you go to work on the blade, this will get all over you.
The veg oil is stickier, and will not be "thrown" off the blade as easily. It also will not smoke on a hot bar.
Mix oil. Motors and fuels change with time. The new units not only require a different oil to fuel mixture, they also require a specific octane of fuel. The oil that is required is designed to desolve in the fuel, and stay suspended.
If you use anything different,you will gum up the carb.
Same people selling vegi oil were selling snake oil a few years ago! Drain oil is fine for bar. Tighter tolerances allow less oil to gas. You can use 16:1 but it will smoke more and start harder. You can use 30 wt. But warranty says it has to be 2 or 4 stroke oil.
Technology does change. My gasoline powerd equipment (chain saws, weed eaters, etc.) all use a mix between 40:1 and 50:1. I have run everything on 40:1 for years with no ill effects. It's a bit rich for the 50:1 rigs, but I've never had a fouled plug!
For an oldie like me, it was quite a shock. I'm used to the 1960 outboard engines!
Your the one that spent the bucks for a new chain saw. If you want it to go old before its time, go ahead and use motor oil for the bar lube and gas mix. The newer engine is more efficient and burns cleaner than the older saws, and that's why the manufacturer specifies 50:1. The vegetable oil is usually recycled from a fast-food french fryer and is perfectly acceptable for chain lube and has the advantage of being ecologically friendly because it will bio-degrade. Don't be cutting any logs when the bears come out of hibernation because if they smell the french-fries or popcorn oil, you're next on the menu.
30 wt. oil is to thin for the bar a will not lub it properly and run out faster. If you use it in the gas it won't mix right and you'll burn up the motor after while. The differences in the oils we use today along with the technolgy of the new saws not needing so much oil. Newer oils have alot of synthetics in it that cools and lubs better.
