So I have a quart of Pennzoil TCw3 that I picked up on a garage sale a few years ago. At the time, I just saw 2 cycle oil and cheap price, and didn't know that it is for water cooled engines. Well I have an old Echo string trimmer, and a new Stihl leaf blower, and am wondering if I could use it up in these machines. I know some say don't do it and others say they have used it for years and no problems. I am running a 40/1 mix in both. I actually forgot what the Echo called for, but the Still called for 50/1.
