Do not just run any oil at 24-1.
Mine also says 24-1, and while that is fine for some oils – others will foul and run like garbage that rich. It really is all about what oil you are using. Go to a local store and get a decent oil, read the bottle. If it is a 20-1 oil (most likely mineral based) then run your 24-1 and you are good to go. Synthetic oils for the most part will be 32-1 to 100-1… using the manufacturer’s recommendation. Oil I use is 32-1 to 50-1… I have ran 50-1 for years and it is perfect.
A average sized bottle will last you a long time…. and mixed right, you can use it for weed wackers, blowers or whatever so it doesn’t sit too long. Add a stabilizer, and mix as little as possible at a time to keep it fresh.
