I recently purchased my first camaro after years of wanting to get one. I found this camaro that has been restored for the most part and has a recently rebuilt engine in it. but for having a V6 this car seems to be guzzling down gas. i've been averaging 12-13mpg and i've honestly managed to be light footed on the gas because it still isn't insured yet . i know the only problems it has is low low oil pressure when the car warms up, the water pump leaks because the bolts holding it on need to be re-thread, and the engine fan doesn't turn on but the owner says that he may have bought to cold of a thermostat. other things i noticed is that the headlights tend to dim and brighten when idling but this is probably not the reason for the poor gas mileage. what should i be checking to figure out why my gas mileage is so poor.
Thank you.

 

well first check the timing on it, retarded timing can cause those sypmtoms. as for the coolant fan, they should only turn on when the car begins to get hot. last but not least, your alternator is getting weak. it might last a lil longer but id replace it as soon as ur funds are available.
