Hi Paul, and a warm welcome to the forum. Its great to have you aboard.

Generally, we use 25:1 for most 2 stroke applications, and we have had no issues with it...the oil that I use is Shell 2T in the 200ml plastic bottle. I also recommend that you use premium unleaded; as some fuel retailers have a percentage of ethanol in the blend, which should not be used in small engines (It can affect the seals, gaskets etc).

What does concern me is your warranty.....does the 2 stroke mechanic work for the dealer that you bought the blower from?.....If he does, I don't think you will have probs running 25:1, which in effect is just running more oil....which for engine life is a good thing.

Once again Paul,
