Third UOA on this 2.0L, K20Z3 Honda engine. Getting 27-28 city/30-34 hw mpg...no lie. Honda Filtec, LC20, no make-up oil, Shell Premium gas and normal smooth driving. Warm-up about 30-90 seconds until it falls off high idle and drops to 1,500 rpm. EASY driving first 2-3 miles always. Occasional spirited acceleration, on ramps, passing on two lane country and mountain roads. No rice boy racing.

BLACKSTONE COMMENTS
M....: We would say your Civic has moved past the break-in period at this point. It looks terrific. The universal averages column shows typical wear from this type of engine after 5400 miles on the oil. Your short oil changes have allowed the engine to complete wear-in quickly (you may find that copper still drops by a ppm or two), and we think it would be fine if you wanted to start running synthetic oil. The oil was in good shape physically, containing no moisture, fuel, or coolant. The air and oil filters are working well too. The slightly low viscosity is common with this engine.

Waiting, and waiting
, for my Amsoil Ea013 filters to get here and then I'll switch to synthetic. Will use VP Racing Fuels' RS530 5W/30, a thin ester based street oil. (No LC20 for awhile.) Started using FP60 today. I'll be uber-happy if the VP equals much less beats these Havoline conventional oil numbers. Longer OCI's for this oil. Hot season coming soon. (Low 80's today.)
Half a bottle of beer each for the Japanese who built this engine and the Canadians who put the coupe together.
