Is 10W - 40 motor oil a two stroke oil?

Question

I have a Spear & Jackson petrol brushcutter with a 40:1 ratio for petrol: oil. The bottle that came with the brushcutter said just Two Stroke. I can't find the instructions now but I know that it said something along the lines of making sure it was a 40.

Help!!!

Answer 1

no

Answer 2

No it is not. 10W-40 is motor oil for a regular engine not a 2-stroke.40:1 refers to the mixture of gas:oil In other words 40 parts gas to 1 part oil.And the bottle will say that it is formulated for 2-stroke engines

Answer 3

No! No! No! You must use a 2-cycle oil to mix with the gasoline . 4-stroke oil has additives which will clog things up.

Answer 4

Absolutely not. There is another section that has it. It's more expensive, be ready for that. But you cannot use 10w-40.
