Chainsaw Oil? Two reseveroirs – 1 for gas/oil mixture and the other for oil?
I am borrowing a gas chainsaw from a neighbor - but he is not at home today to answer my question. I have searched high and low for owners manuals - but nothing. I know I need to mix the 2-cycle motor oil with gas (duh). But I noticed a second oil reseveroir that is bone dry - - is this the chain oil? If so, can I use the 2-cycle oil for both the chain oil and gas misture?

NO! NO! NO!……You have to use bar and chain oil in the second reservoir. Wal-Mart carries cheap stuff or a local farm store will have better quality bar oil. When you buy two-cycle oil, there is a mixing guide on the back. Just be sure you know what mixture the saw requires and follow the label directions to achieve proper mix ration.
NO! It's a special lubricant for the chain;-{ usually red.
Perhaps he doesn't realise he needs it;-{ buy him some.
JMW is correct
Bar and chain oil is what you need from most auto/hardware stores. In a tight I have used regular 30 weight motor oil. just be sure the 2 cycle oil and gas mix are right.
