I'm getting poor gas mileage around 15mi/gal. I noticed it after my last visit. Is it because of the oil used(Motul)?

 

Oil used shouldn't have an effect on gas mileage as long as it's clean (even then, shouldn't effect much).


How's your right foot, what RPM's are you shifting at, etc?

 

That's about average

 

its bec of your heavy right foot lol

 

Damn... I wish I could get 15... I average about 12.8

Too many shifts to redline and i like to keep it above 5000... that sounds is soooooooooooooo addictive!

 

Geez, you guys must be driving full blast everywhere you go. I get 20 to 21 around town and 27-28 on trips.

 

Yeah, I guess too many "street races" around here. I got stop gunning the pedal at every stop light.

 

We ain't got no gas mileage, We don't need no gas mileage. I don't have to show you any stinking gas mileage!

 

I am somewhere around 15mpg too(street). I think you are average

 

Say what???????? I think my best ever was like 17 and that was on the freeway cruising.
I have been at 11 MPG for weeks too.

 

Too much downforce with that RS wing

 

Who really cares? My milage varies depending on how I shift/drive, city or highway, etc.

 

Tony, bring it over and we'll trade - you can drive the Scion for awhile if you're concerned about gas mileage

 

the reason i asked because i noticed after getting my 15K service at an independent dealer. i replaced the air filter with BMC and they used Motul instead of Mobil 1; they said i would noticed better gas milage.

 

unless the viscocity of the oil was changed you will not notice any difference in mileage. Suggest sticking with what Porsche put in it.
Is the BMC an oil filter? Make sure it was not overoiled and messing with MAF readings.
