OutdoorKing Repair Forum Forums Repairs and Maintenance Questions On Hand Held Blowers/Vacuums Petrol Blowers & Vac's 25:1 or 50:1 for my Shindaiwa EB3410 blower?

Hi

I bought a Shindaiwa EB3410 blower (2-stroke) from an authorised dealer in Sydney. The instructions & warranty say that I must use 50:1 so as not to void the warranty, but the 2-stroke mechanic said to use 25:1 as the engine will last a lot longer. He said he can tell the difference between an engine that has run 50:1 as opposed to one that has run 25:1 just by looking at it.

What should I do? Is 25:1 really better for it in the long run as I intend on keeping it for many, many years?

Regards, Paul
