When I talked about changing to synthetic oil in my Explorer I was refering to the fact that synthetic oil helps with fuel mileage by doing a better job of reducing friction in the engine than patrolium oil. So the K&N filter along with the synthetic oil increased my mpg.

 

I doubt the air filter increased mileage. A more free flowing air filter will increase the amount of fuel the engine pumps into the cylinders to compensate for the increased airflow. It could increase mileage on the interstate, but city driving it would decrease mileage. I'm pretty sure the synthetic oil is what gave you the increased mileage.

 

I think it was a combination of the 2. Where are you getting the notion that with better air-flow that your fuel mileage would get worse with city driving??? :? You are wrong in a major way! Not the first time though. :lol:

 

James, you seem to get slammed every time you post. I admire you for keeping your cool.

 

Because if airflow increases then the amount of fuel the engine is fed also increases. The ECU has to maintain the same air-to-fuel ratio, so if you increase airflow the ECU also increases fuel flow by the same percentage, thus you're using more fuel.

When the throttle is constant, such as crusing on the interstate, then the ECU lowers the timing and air to fuel ratio to conserve on gasoline, in which case more air would behoove fuel economy because a higher ratio of air in the cylinder allows the fuel to combust more evenly giving more efficiency per unit. Thus increased airflow helps economy in a highway situation.

I've also experienced this first hand after installing cold-air intakes. Decreased city mileage, increased highway mileage.

 

James... Get ready.... Are you sitting down???? Okay here goes... .... What you have said above is.... (Are you really ready for this???).... Here it is.... RIGHT!

If you will notice that the mileage figures I gave were w 60% HWY and 40% city..... That's where the increased fuel mileage comes into play.

 

What I say is usually generally correct. You just want to go into specifics I don't mention in order to try to maintain your fictional role as king of these forums.

 

Actually, no, Wes generally makes statements here in the Crossfire forum regarding a vehicle he owns and knows about. YOU makes statements about a car you do not own and is apparent from your posts know very little about. IF you always caveated your posts as being GENERAL information that MAY or MAY NOT be applicable to the Crossfire, people probably wouldn't jump in your shxt so often. But when you make statements that are :!: WRONG :!: or have no applicability to the car this forum is setup to discuss, people are gonna jump on you. :wink:

 

Right on D.B. This guyi s a mo---

 

That's it... I tried to be nice to you and you just want to keep the crap going.... I'm done with your ignorant ***, James.... Go plat with your Acura and have a nice day! :?

 

Finally

A member also.

 

LOL !!!! :lol: :lol: :lol: :lol:

 

Oh schucks,2 bad

 

They love me, they really love me!

 

Call a spade,it's a honda 5sp.

 

And it's as fast as your Crossfire in the quarter.

 

Just don't hit any squirls they might be one of your relatives!

 

LOL we all know I dont mind pickin on James.. but I can't diss his car to bad! that RSX is a nice car... it may not be as nice as our crossfires to us... but I'd take a RSX and deck the hell outta that car! It's one of the BEST customizable vehicles on the market and it will last forever... go JDM... and go Crossfire.. I hope James DOES buy a Crossfire... then I can change my F@#king avatar!!!!!!! :twisted:

plus I don't get the Squirrel joke :lol:
