i got 23 mpg
i recently been working on my truck. 2001 mazda b3000 3.0 with almost 150,000 miles. yeah i know a mazda a ford ranger in drag. but it was about 2500 cheaper than a bone stock ranger at the time i needed a new truck.
anyways...recently had to repair my timing chaing cover due to leak of coolant. and my radiator also had a crack in the top of the plastic part on the sides. so i went ahead and changed out most of what i was touching to repair the the gasket to the timing chain cover plus some. all these within a couple of months
hi flow clutch torque converter
oil pan gasket
my timing chain and gears still looked new so i did not change that
hi flow thermostat says it supposed to let 50% more coolant and i say it does my temp gauge is always cooler now.
and recently changed out
first seafomed one can in tank then later after i ran that through the tank i sea fomed entire can through brake booster.
new spark plugs
new coil pack
new spark wires
new fuel filter
new cam synchronizer
also cleaned MAF and Idle control valve. for the MAF i used brake cleaner. for the idle control valve i took it off put it upside down and poured seafoam and used q tip.
now the gas mileage
when i first got the truck i lived in the city. i would get 285 miles per tank. moved to country and have been getting 330 miles in tank. the first full tank i noticed my needle was moving down slower but didnt record my mileage the next tank of gas it moved slower again i got 355 miles out of the tank of gas and that was with me filling up when my low fuel light came on. usually the needle will get below the red line empty to get my 330 miles.
when i seafoamed tons of smoke and the water condesation out of the tailpipe had a bunch of carbon flakes (tiny). my number 4 cylinder spark plug was black and probably about ready to foul. this was before i seafoamed i took them out to see what they looked like before and after. seafoam works. #4 was not perfectly clean but a lot better. the spark plugs had about 90,000 miles on them. seeing the before and after i know now i dont need to wait to seafoam through the brake booster right before i change the plugs because it is unlikely to foul the plugs.
now i just need to change rear brakes, rear differential fluid, new tailgate handle, and possible a starter or solenoid or fuel pump maybe both after i test them. new tires and shocks.
sorry for the ramble. went to change my brake shoes and undoing my first lug nut i hurt my back. laid on the driveway until my son came out and saw me. i am now on my usual dose of relaxers and pain medicine.
