i have 2012 FJ i would to improve my gas mileage along with performance, what are my options? Thanks
Sorry for quoting an old post...but there's a psychology to the way a gas gauge reads. This old Motor Trend article should be required reading for all gear heads. Little White Lies From Your Dashboard;And also shows that the Gas Gage is poorly designed and or engineered because my FJ showed E and the light was on but according to my calculations I still had 4 Gallons to go and quite possibly another 80 miles..............
My point is I know I traveled 303 miles on 15 gallons at 70-MPH which should equal 20.2-MPG. And also shows that the Gas Gage is poorly designed and or engineered because my FJ showed E and the light was on but according to my calculations I still had 4 Gallons to go and quite possibly another 80 miles..............[/QUOTE said:Those are all good numbers from the figuring I've done on my 2012, and being that the FJ can get you lost in the hills an 80 mile reserve is a good thing! :bigthumb:
Don't know about Tahoe, but when I compare actual gas on gas station and what SG-2 tells me difference is 0.1-0.2 gallons maximum , for 16 gallons it is 1-1.5 % if I using same pump and same gas station.If you are using a scan gauge it is NOT a super precise device that can tell you exactly how much fuel is used. It has no means of measuring actual fuel flow, just a calculation based on sensors/ ecu parameters such as injector pulse, and throttle position. The scan gauge is accurate in certain circumstances but not others. Just as I fooled a 2010 Chevy Tahoe into calculating 35mpg on a 220 mile trip by keeping it running in cylinder deactivation mode and coasting a lot. When you start throwing in 99mpg numbers into the works your mpg will skyrocket despite the fact it really isn't going up. To much weight is put into the infrequent very high mpg numbers.
I beg to differ. If I get less than 20 mpg in my normal everyday driving (no trail riding), then something is wrong. Mine is 100% stock and an late 2006 model. I've posted this many times going back to 2007 on this very forum.The reality is your not going to get over 20 legit mpg in a fj cruiser that's a auto and 100% stock, as a baseline for all the time.
