Just wanted to share and brag a little.
before I joined this site my highest MPG was 28.7 (Up from the 20.1 it was getting when my dad handed the keys to me).
A lot of work has gone into this thing.
Since I have been on this site I have lowered my top speed from 65-70 to 55-60. Also, I have been putting on my seatbelt before I start the engine instead of afterward and letting it run for 30 seconds doing nothing while I adjusted everything (waste of gas).
Guess what? My MPG has jumped to
30.23!!!!
I don't think it has ever gotten that in the past? Just changing those two bad habits showed a nice gain (not sure the persentage? Someone care to do the math for me?).
Here is what I have done this past weekend for my next tank.
I bought a timing light. My timing was at 3 degrees. Suppose to be 8. turned the distributor up but would not go past 5 degrees. Figured the idle was too low (don't have a tach). The idle screw was at 1/2 turn from fully close! twisted the idle up to 2.5 turns out and was able to get the 8 degrees needed with the distributor at the halfway mark. Runs much better.
Found the engine to be 3 quarts low!!! Added oil and changed the rear axle fluid with the recommended 75w80.
Last but not least I bought a roll of white duct tape and masked off the grill edges, gap between the bumper and grill and the grill inlets itself. I left the 2 horizontal openings below the bumper open for now.
Anyhow, I'll see what happens on my next tank!
