1st, drain out that `old`fuel-fuel over 3 months old,(unless a fuel stablizer additive was added at time of `fresh`fuel put into tank)replace fuel filter w/new. FILL w/fresh fuel-do not allow fuel level to fall below 1/4 tank at ANYtime.2nd,warm up engine to opp`temp-to when the electric cooling fan starts,then drain the oil/filter replace w/correct weght oil & new filter.Do NOT fill above `full` mark .4th, becouse such a short drive to `mot`ctr,make sure engine is at full opp` temp`-no `cool show-ups`. Try these measures first. Depending on mileage & engine condition,replace spark plugs(and/or check gap,type,etc`) and the lamda(oxigen sensor(s)coolant thermostat(if engine not reaching opp`temp`),these items also may require replacement. Hope this helps;John
