Newb FAQ

[Red Tick]

First let me apoligize for improper placement of this thread, if infact it is in the wrong place. I saw only one other FAQ thread and was rather lengthy. So inorder to get maximium input I put it up front. Moderator plz move at your discresion.

Ok here is the skinny. These are basic things I have heard can effect MPG. I make no claim to any of these. I am asking if you guys could offer input and then maybe we can take agreed answers and rewrite them into a sticky FAQ thread for Newbs (like me).

Here we go, from the ground up.
(Of course each of these answers could very depending your application & setup.)

1. Fuel
a. Low grade fuel is cheap and moderatly efficiant
b. Mid grade fuel is a little more in price with best economy
c. high grade highest cost with best preformance with least efficiancy

2. Fuel Type (Gas vs Dessiel)
a. Gas delivers ok to good economy
b. Dessiel good to great

3. Winter Fuel vs Summer Fuel
Does the fact that companies in the U.S. oxyaginate fuel durring the
winter hurt your MPG

4. Wheels
a. Slightly taller tires improve MPG
b. Wider tires hurt MPG do to a larger footprint (Surface area contact)
c. Lighter rims Better MPG vs Heavyer rims Poor MPG
d. Proper air presure in all tires will improve MPG

5. Suspension
Does suspension effect MPG in any form. i.e. lower ride hight less drag
better MPG

6. Engine Componets
a. Engine cooling i.e newer more efficiant radiator and fan will improve
overall preformance resulting in slightly lower MPG
b. Improving air intake and exhuast will improve preformance and depending
on how that application is tunned might result in slightly improved MPG.
(Basicaly more air in higher oxygen fuel ratio requiring less fuel, more air
out les resistance. Better preformance.)
c. Speed effects total MPG. Best average of speeds 50-60mph depending
on car type yields better MPG
d. RPM shifting at slightly lower RPM's can save gas, i.e. not hotdoging it!
e. Manual is better than automatic for MPG (on average remember newbs
here)
f. Those tornado things you jam in your air intake hoses? (as seen on tv)
g. Keeping your Carb or injectors clean.

7. Car body
a. body kits and or wings improving airflow resulting in minnor MPG
improvements.
b. overall wieght lighter means more MPG

8. Flux Capasitor
a. Just kidding...

Ok just some basic things I have heard before. Are they ture or false and what is better? Remember these are basic concepts for the average newb and their average car. I understand some cars will yield better results with diffrant aproaches than others. Just some things the average guys or galls can do to get better MPG. So if we can get some agreed apon answers we can get a basic newb FAQ
