fuel
 

I HAVE A 94 BLAZER FULL SIZE...HOW CAN I MAKE IT MORE FUEL EFF.?..JUST WONDERING WITH A 350 ENGINE....THANKS!:icon_shrug:

simple ways to increase mileage is check your tire inflation and inflate to the correct psi (can be found on the driver door jamb), dont inflate to the max psi rated on the tire. check your air filter and if its dirty, replace it. also things like the "tornado" and gas line magnets dont work, so dont waste your money. when ever your driving pay attention to the RPM's try to keep them as low as possible (1000-2000 RPM's will save alot of gas). you can remove any excess weight from the truck like the spare tire (but i wouldnt recomed this unless you have roadside assistance). Reduce drag by removing a bike or ski rack when not inuse. dont idle, Turn off your engine if you’ll be idling for more than a minute or two. Starting your vehicle does use a burst of fuel, but not as much as allowing the engine to idle too long. and personally i unplug my ac compressor clutch in the winter so that it doesnt cycle on and off. just be careful, because if you leave it unplugged too long your ac compressor can sieze up. you could also change your fluids (engine oil, transmission fluid, and gear oil) to synthetic fluids. synthetic fluids have been proven to reduce drag and that allows less friction between moving parts.

Thanks !...i see you have a k&n air filter is that a good investment?

personally i love it, as soon as installed it i got better throttle response and you can feel the increase in horsepower. it saves you money in the long run too, when it gets dirty i just soak it in a dish soap/water mix for an hour, oil it and its like brand new.
