Spark plugs on 94 cavalier rs 3 speed automatic

Can anyone tell me which spark plug will give me the most gas mileage? I'll need the brand name. Please help me,the autolites are giving me horrible gas mileage. What brand of plug wires should i use?

no brand will give you better mileage then any other, if your autolites are new, then your bad gas mileage is being caused by something else, since your car is 13 years old, there are alot of possibilities

Guess what guys? I know some pretty good mechanics around here and sometimes have trouble getting in touch with them. I talked to one of them and he said my sparkplug wires were bad! Does that sound about right? I replaced them for $17 plus $20 labor. According to the advanceautopart website,the nkg platinum spark plugs can give alittle more gas mileage and possibly more hp because they burn better or something. I wouldn't know for sure unless I tried! Its also time for an oil change,so I'm getting it done tomorrow after I get off work and I'm using super-tec full synthetic 10-w30,i'd use the 10-w40,but they don't have it in the brand. Any feedback would be appreciated! Oh yea,anyone tell me if it'll be safe to put in a can of engine restorer at the oil change. I know its safe with the conventional oil,but I use full synthetic,and I do run it 100 miles a day on the interstate!
