C152 PLT MISCALCULATED FUEL REQUIRED FOR FLT; AND LANDED ON A ROAD WHEN THE ENG BEGAN TO SPUTTER FROM FUEL STARVATION.

Narrative

I WAS FORCED TO LAND A CESSNA 152 OFF ARPT. I HAD FLOWN THE PLANE TO ZZZ1 AND WAS ON THE RETURN FLT BACK HOME. ENRTE; I BEGAN TO GAIN A 15 KT TAILWIND FROM THE N. I MISTAKENLY FELT CONFIDENT THAT THIS COMBINED WITH THE FUEL TANKS (BOTH NOW SITTING AT 1/4) WOULD ADEQUATELY CARRY ME TO ZZZ2. MY TAILWIND TURNED INTO A 15 KT HEADWIND FROM THE SW. I HAD TO MAKE A DECISION AND TURNING BACK WOULD HAVE MEANT TRAVELING FURTHER AND KNOWINGLY INTO A HEADWIND; SO I PRESSED ON FOR ZZZ2. AFTER CONTACTING APCH; I WAS HANDED TO THE TWR AROUND 10 MI OUT. I KNEW I WAS LOW ON FUEL. AFTER THE TWR ASKED ME TO FLY A R DOWNWIND FOR RWY 27; I REQUESTED A DIRECT R BASE ENTRY TO SAVE TIME. 2 MI SE OF THE VOR; WHILE SETTING UP FOR A LONG BASE LEG; THE ENG BEGAN TO PRODUCE MINIMAL PWR. I WENT THROUGH MY PROCS. I MAY HAVE MADE THE ARPT; BUT WITH OTHERS' SAFETY IN MIND I FELT IT WAS BEST TO MAKE THE PRECAUTIONARY LNDG. I PITCHED FOR BEST GLIDE AND TURNED AWAY FROM ZZZ2. I CALLED THE TWR JUST AS I FOUND A ROAD TO LAND ON; GAVE HIM MY INTENTIONS AND SOULS ON BOARD. I SAFELY LANDED ON AN EMPTY ROAD; WITH NO DAMAGE TO PROPERTY OR INJURY TO MYSELF OR OTHERS. AFTER SPEAKING WITH THE ARPT FIRE DEPT AND LCL FBO MGR; WE ALL FELT IT WAS IN MY BEST INTEREST TO SECURE THE ACFT OVERNIGHT. THE FOLLOWING MORNING THE ACFT WAS INSPECTED BY AN A&P AND WAS THEN FLOWN TO ZZZ2; FUELED; AND RETURNED HOME. ENRICHENING THE MIXTURE TO BREAK IN THE NEW ENG LED TO HIGHER THAN NORMAL FUEL CONSUMPTION; AND I DID NOT PLAN ACCORDINGLY TO THIS. I BELIEVE HEADWINDS; POOR FLT PLANNING; GAUGE MISINTERP AND PLT FATIGUE WERE/ARE ALSO CONTRIBUTING FACTORS TO WHAT HAPPENED.
