What should I "B" expecting?

So i bought my current mazda b2000 a few weeks ago and have run a couple tanks out of the ole truck. My first tank was averaging 15.5 mpg. My second and third tanks have avged about 16.33 mpg. Is this what I should expect to be getting outta this little 2.0? Little back ground, she is BONE STOCK running the ole carb with a 5 speed tranny. She is an ext cab. So far i have done the basics changing fuel filter, new thermostat, adjusted the timing a little which got me the almost 1 mpg gain, and adjusted the idel set screw as was ideling high. I just bought some NGK G power plugs i am gonna try tommorrow. Any Hints or am I just gonna have to live with v8 milage without the v8 power?

yup sounds about right..do a tune up you may pull 20

^^^wow.... for cereal? i get 24-26 mpg out of my 2.6 liter... 5sp daily driven...


maybe try carb/injector cleaner additive in with the next fill up? i used carb/injector cleaner, octane boost, and fuel treatment to my tank every couple months (did this on my 89 2.2 when i had it), and my mpg has always been over 22mpg, both trucks. my 2.2 usually got 21-24. my 2.6 averages 24, but has been seen as high as 28mpg, and its got 259k miles on it...

your 2.6 is injected...better milage

Did run some sea foam thru it and seemed to help a little. I noticed that several of the guys like the NGK brand plugs... gonna try a set in the am....

yea i am hopin for round 20 thats a 4 mpg increase over where it is now

yeah... but its a 2.6! bigger engine usually doesnt mean better mileage. but i do like how less gutless mine is over the 2.2. i thought my mileage was going to go to sh!t when i got the 2.6. my 2.2 was carbed, and felt "quick" enough for me... but after driving the 2.6, i dont think i could go back... that and mileage was about same between my carb'd 2.2 and my fi 2.6

as for plugs, it is a japanese engine, and the NGK's are "supposed" to be specially designed to provide better efficiency for japanese engines (not sure how much i believe that, but i still buy NGK, usually the cheaper plugs). also check cap/rotor, and wires... the older those are the worse your mileage as with any vehicle... maybe upgrade igntion if you plan to really get into your truck.

wow that sucks i get bout 30-34 after i put on my weber bout 400 + out of a tank dont have gas hand so i use a stick
