Hey guys,
I bought a 1984 Carbureted inline 4 Mazda B2000 truck. When I got it, it was in DIRE need of a tune up. I have replaced the plugs, wires and air filter, getting supplies for an oil change and fuel filter.
Onto my question: I totally removed my truck bed and topper and have gone from 100 miles per quarter tank to 170 miles per quarter tank (small engines greatly benefit from weight reduction, this reduction equaled -500lbs) And I have started to fabricate a very basic ply wood boat tail.
Does anyone know if the added weight from the boat tail will change the mpg in a considerable amount and where will I see the most gains? I'm assuming highway will be the best.
I just need some input, Thanks guys!
** UPDATE **
I found this pic on google, cant find a camera right now haha
