Chain saws

[Coyote machine]

I'm a novice when it comes to felling trees and appreciate the chance to read and learn.

Dropped a few large trees around the homestead and paid to have others taken out because if something went wrong it could have taken out my place or a neigbors.

One comment on octane.

Gas BMW's are typically derated for North America and BMW cites lower octane fuel as the reason.

In Europe... premium is several points higher than what is typical here.

When I visited the factory I asked what would happen if 87 was substituted for 91 North American and learned the engine will compensate and performance reduced.

BMW is one of the few cars I know that require premium across the line.

BMW makes chainsaws?! I never knew! They must be expensive:laughing:...

I didn't properly present what I what saying about higher octane fuel.

Higher octane fuel than necessary is a waste of money. Higher octane fuels require more energy to ignite. Gas has a BTU around 114,000, 87 octane gas usually has a couple thousand more btu than 93 octane. Higher octane is typically blended with MTBE and other additives to reduce knocking.

When I've needed to call Stihl, I asked about what fuel to use. I was told using anything within a few points either side of 89 was fine. I've had the same answer from them each time I asked.

Did you speak to different people each time you called? Were you calling numerous times to see if they would give you different answers?! How many...aw, never mind....

Most anything with a turbo now calls for premium, VW for one. My Dodge Ram with the Hemi engine calls for mid-grade gas, although regular will work if that's all you can get. Fuel economy is slightly worse with regular I'm told.

Yes sir. For a still standing tree, the wedges can be a bar and chain saver.
But once the trunk is horizontal, there are times when that 2nd saw is much more helpful than the wedges.
So 2 saws & 2 wedges and see if I can still pinch the bar. Odds are I'll find a way.

Here's a good video showing how to use one wedge to prevent the cut from closing up and pinching the saw when the trunk is horizontal.

That's the right way to do it!

Yep, that's a very good example. I like how someone in the video yelled "cheater".

I've owned dozens of Stihl machines and have called Stihl several times over the past 20+ years for a variety of reasons, mostly parts. Currently, I have 2 chainsaws and a cut off saw. Up until I retired, I used them for work. My MS280 is the only one that hasn't been used for work.

2001 Corolla new... mileage would drop almost 2 miles per gallon on 87 vs 89.

With 89 car was solid 40 mpg highway... never 40 mpg with 87

4 posts NF and you gotta learn something. We all like to contribute and help out where we can. What is stated needs to be accurate and not all over the map. You mention MTBE as an additive as if it is still being used. It's not, being banned several years ago. Ethanol is the current joke now. They banned MTBE not because it was polluting the air which is ok to do apparently. It was banned because it was polluting our water supplies and still is.

Yeah I need to have a couple of those in my hip pocket.

Lighten up a bit. It's only his 4th post. Hopefully you didn't just make it his last. Everyone is mistaken in their facts every now and then.

I know if I got that kind of a welcome to a site I wouldn't be back.
