I recently Added poweraid spacer,S&B air intake, magnaflow catback and a Hypertech Max program for regular gas with all that Im getting 13.8 at 60mph highway. Im pissed, just give me the advertised milage. Fat chance. Please help any suggestions?
I did the nismo cold air intake, banks exhaust got a lot better after that it was around 17-18 every where my truck is a 08 pro4-x. Then I put a 3" lift on the front and a 1" in the back and a little bigger m/t tires and now i'm getting 16 every where. I have also noticed that when the gas stations switch to the ethanol in the winter it gets 1-2 mpg worse. now in the phoenix area they use it year around which sucks @$$!! There is a lot of info about gas, a lot of them are myths so be careful what you believe. ethanol burns faster than gas but not as hot so you loose power and mpg when you use it! Way to go big brother and the huggers!!
I have a 06 king cab 4x4 with tonneau cover and tow pkg. I get about 15 on the highway @75. My driving usually involves snoqualmie pass @3300 ft .
I don,t drive my truck often but the only thing I,ve found that really works for milage is to slow down. I made a trip from central washington to Salem Oregon and back. about 720 miles and got 16.7 mpg!!! BUTTT I drove 60 on cruise the whole way.
This is great milage for a Titan with the tow pkg. I just can,t stand 60mph very long.
I just haven,t seen any other add on, or magic elixer that works.
Just my opinion.. Rick
I asked a salesman one time about this. His advice was for me to come look at Altimas! Seriously though, Cold Air Intake will increase your HP and give you a little better fuel economy. Exhaust seems to make mine just sound better and deeper. Noticed the difference when I did the CAI
Once i was out of my manufactures warranty i started doing my own oil changes and started using MOBILE ONE synthetic Fluid...and it helped out my gas mileage by 1.5MPG. i average 15/16 MPG i use to average 17/18 before i put 20inch chrome wheels. Stay away from Upsising your wheels if u care about gas MIleage! i also have a AEM air intake and Magnaflow exaust but i enjoy the sound so much i end up accelerating more than i should so dosent help much.
