Fuel Saving Tips
Not advertising so not mentioning any products, but i just bought a device that plugs into your obdII and it tells me my instant mpg and avg mpg. also gives me many readings that i dont fully understand and can read codes and can reset engine light (usefull for inspections) but i have learnt a great deal about the way i drive by staring at this device, luckily didnt hit any trees on the way to work (yet) but i find it useful since i can tell what footing my car gives me the best mileage.
