Fuel Milage

[Glockwarrior]

I know it has been talked about before...but lets talk again.
I have a V6 97 SR5, it should get about 16-19 mpg right?
I am getting 14 to 17 at times. Is it because I am running the AC all the time? I once heard that vehicles below 2000's get less MGP's w/the AC running.
Thanks

Back to basics, man. Plugs? Wires? Air Filter? Clean MAF and O2 sensors? Clean Injectors? Fuel Filter?

Also make sure your calculations are consistent and accurate or else your MPG will be way off as well.

Depends on many things, driving style, condition of the engine components, etc.

I would say you are below average though.

I drive pretty normal I dont think think I have ever even got on it since I have had it. the motor has 190000 on it, and I have all the records showing that it had regular maint. done to it. It is all stock nothing done to it.
The best mpg I got was 20..that was on the highway, the worst was 14.9 it was only aroung town but for the most part it is getting 16-17ish (alot better than my Jeep)

If you're running the A/C alot then your mileage is pretty normal for any year of 3rd gen.
I get 15-17 around town and 21-22 hwy and I'm a bit of a leadfoot with no A/C on.

Yes. My mileage drops exactly like you are describing when I run my A/C a lot when driving in the city/suburbs. Now I generally do not use a/c unless I am on the highway. At highway speeds the engine is producing plenty of 'extra' power that the a/c can use.

Whenever you got a lead foot or run the ac all the time it is gonna drop your mileage. the ac just puts so much more of a load on the motor and is gonna cause it to burn more gas. Just like a lead foot will. I rarely drive under 75 80 but when I do I notice the gas last me a lot longer.

By the way does anyone know how much gas is left in the tank when the gas light comes on??

If you've got a problem with your car, its probably not too bad of one.

I have the 4cyl, its supposed to be better with mpg but my average has been 14 since I bought it.

I just got 16.6 for the first time last fillup.

I cleaned my MAF, swapped for a K&N intake, cleaned the throttle body, and did a header swap. With all of that, it still barely budged, between 14-15 maximum.

I went over maintenance records from the woman who owned my 4Runner before me, she used nothing but shitty gasoline and shitty conventional from jiffy lube.

In order to clean out all the shit in my engine, I switched to Castrol GTX synthetic 10w30 for 7,000 miles, did another synthetic oil change a few days ago, and holy shit on a mother****ing stick.

My car is quicker, and better on mileage. On my first fill up, I got 16.6 mpg for the first time ever.

Now I need to swap out the rest of my exhaust (clogged catalytic converter, 2 exhaust leaks, small pipe)

So really, all I'm saying is that your car may just need some easy preventative maintenance, like a good synthetic oil change or a cleaning here or there. I got 2 mpg just from oil.

I can only hope for another 3 from exhaust.

Thanks for all the info...I guess I am not the only one w/less than great gas milage.
I see alot about..what is the "Deck plate mod" Could it help in the mpg department?
