Hi there. I have a '85 olds cutlass supreme v6 that is completely stock, except that previous owner changed carb to a mechanical one. I'm getting horrible MPG on city, 10 mpg is not uncommon. When I go on long rides it can go up to 15-16 mpg if steady speeds and no sudden acceleration. This is without even turning the A/C on!
The car has new tires and most suspension components have been replaced with new (also aligned without issues).
Has most of the maintenance items replaced with new (spark plugs, wires, air filter, etc.).
It is hard to start when cold, sometimes having to pump the pedal 4-5 times or else it will stall. Once it starts you got to let it warm up or accelerate slowly. If I press pedal halfway right away it dies. Once engine is warm it starts on first try without issues. It sometimes smokes if I'm at WOT.
What should I do to help increase my mpg? I'm happy if I even get 16-18 at city since I do most of my driving at low speeds and sometimes stop n go traffic. I want to keep the car as stock as possible and avoid expensive (100+) mods for now.
