I think it is a GOOD investment to spend the 50 to 80 dollars on a set of Taylor or Accel 8mm spark-plug wires PLUS another 15 dollars for a high-performance cap and rotor for the truck, as this increases fuel mileage by 10% or so, be it efi or carbureted, some quad-plat spark plugs MIGHT help as well thou double-plat really is good enough, and Autolite is cheaper than Bosch thou Autolite does NOT make quads AND most Bosch comes pre-gapped while Autolite does not, still a dollar is worth gapping it myself. Lets remember the higher cost of fuel only affects driving to-from AND anytime we're using fuel-powered equipment. Shovels, rakes, tarps, wheel-barrows, loppers and garden shears (surely there's more) ALL operate without fuel and can be used to do little extra stuff they did NOT ask for that helps the yard look better while we raise prices I feel we need to give the customer something in return as well. What's 5 extra minutes for 5 extra bucks, really it's us trading a bit of extra (and paid) labor to help pay for the fuel while they are NOT paying JUST for fuel. Another way to raise prices is to work HARDER so as to get MORE work done in LESS time. Yes it kinda sux but at the same rate if I can do an hour's work in 50 minutes and do so consistently without losing quality, then that helps boost my income somewhere around 15 to 20 percent. All of this helps, would like to hear more ideas.
