My .15FE(yes different mfr but still and engine) is through 3 some gallons and still running alright, not like new but it does well.
Yeah really depends on how you treat the engine, to give u an example, my Novamax 21 has seen 8 gallons of fuel and going on my 9th still have tons of compression granted I replace conrod every 1 1/2 to 2 gallons and I clean the internal regularly.
