I don't know if I'd consider "only" 17k hours as a failure. At my rate of usage that is another 80 years.
I am not sure what your posts are trying to say apart from you don't use your engine and you are alright.
That's nice for you then, but what's the point posting that apart from making your self feel good.
The whole point of this thread is to find out if any one is using there generator every day as there main power supply and is running it on WMO as a sole fuel and if they have had problems with ring and bore wear.
The fact you only have put such a very tiny amount of hours on your engine and have not had problems is not proof its not being damaged .
I did not have any problems until the engine clocked up hours so your posts don't count as proof that its a good source of free fuel.
The twin cylinder listeroid that was for sale that the seller was running on WMO may hold some interesting insight to every day use on such a fuel.
