Drop in fuel mpg Drop in performance
Yes, you can increase it with tune-ups and by upgrading the engine.
Tune it up. If its A car you can hope for around 18 MPG If its A truck you can hope for around 14 MPG
EPA estimations are 18 MPG in cities and 28 MPG for highways. However, you can pretty safely expect slightly lower values in reality, around 15 MPG in cities and 23 MPG on highways. The overall MPG is slightly lower than the average compared to other V8 engines.
That depends on the engine, mostly. No matter which option, it wasn't good by today's standards. My 289 2bbl was around 10 mpg before I did a tune up. Now it gets 16 -18 mpg.
14-17.5mpg w/90,000 miles on it and a fresh tune up
Accelerating and braking abruptly, an out-of-tune engine, under-inflated tires, to name a few.
With a DP1600 engine 19-21 mpg on a 009 distributor, with an SVDA distributor 25-27 mpg. Assuming correct carburetor, and good state of tune.
Probably, but I wouldn't try that. It may overload the Metro's tiny electrical system if it is a first generation model 1988-1994. Plus, it would lower your MPG on such a high MPG car.
Full tune up will certainly improve gas mileage. plugs, wires, cap/rotor(if DIS, then doesn't have), fuel filter, air filter, pcv valve to name a few.
Mine gets terrible mileage. On the freeway I have done as well as 15 mpg. Last tank of gas I averaged 11 mpg. Going in for a tune up to see if it helps get any better miles per gallon.
It could be time for a tune up. What kind of MPG are you getting?
