I have used both Trufuel and VP. Tru fuel evaporates quickly, even some of the cans I bought were only 3/4 full and some only half. The guy at the saw shop told me a lot of customers ave mentioned that to him and recommended VP. VP seems to to run much smoother and doesn’t evaporate like Tru does. Put some in my Husky 326L this morning and for an old weed wacker that motor was screamin without missin a beat. I think Home Depot and Loew’s has the cans for 5 bucks. Fuel here in California was eatin my fuel lines, every 6 months had to change them. Just bought a new Echo CS 400 and after a little adjustment here and there it seems like a great little saw for around the property here. I also have a Husky 385XP, which I can barely lift anymore, and a Husky 50 that’s pushin 20 years. I’m 75 years old and I think this Echo might be the last saw I ever buy, if it holds up.
