I have a Stihl 025 that I posted that is recommended to run at 50:1. I have a Hitachi Leaf Blower that is recommended to run at 50:1. Now doing some research on here I see recommendations of 40:1 to 50:1 (sometimes even 32:1) for use in peoples' chainsaws. I figured a good 45:1 would be the middle of the road so I went this route. Now I have slightly less than 2 gallons (used some of it but can;t tell how much) mixed up as follows:
2 Gallons - 93 Octance Gas (No Ethanol, luckily we still have some around)
5.7 oz - Stihl Ultra HP Synthetic
28oz Sta-Bil Red Formula
Like stated earlier this gives me a 45:1 according to the online calculators I used. My main concern was for my chainsaw as it is the most expensive power equipment item I have at the moment and I figured this combination would be good (maybe overdoing it a bit) for it. Now on to the question, I had (being the key word) a Husqvarna 128LD weed trimmer that was recommended to run at 50:1. Long story short, after 2 years it quit working today. I took it apart and saw that the piston and cylinder was scored pretty bad. Anyways after judging cost to rebuild/replace I decided to just buy another weed trimmer. I got a Troy Bilt TRB2044 XP. I will honestly admit that I didn't look at the recommendation first (figured it had to be 50:1 as well), filled it up with my current mixture and did the yard with it. After running it for say 30-40 minutes (weed trimming and edging) I put it up. It ran very good to me at least.
With that said, later on I finally got around to looking at the paperwork and saw that it recommended 40:1. There is no real way to make my current mixture 40:1 anywhere near accurately. Just wondering if y'all think the 45:1 would hurt anything as far as longevity of the weed trimmer? I know now that my next mixture can be 40:1 for all if need be (or maybe I should stick with 45:1), but I just made this mixture and it generally will last all season. Thanks and sorry it's so long.
