I'm complaining that i am getting the average MPG or worse when I am just doing pure highway driving of 70 MPH. Also, when I go a steady 60 MPH, I get my a$$ tail-gated by douches and honked by truckers on the traffic lane (right lane). I am using the instantaneous MPG is see what I am getting constantly, not to calculate my average MPG.
Aren't 4bangers supposed to be fuel efficient compared to V6, V8, Vwhatever # of cylinders?? Also, I don't want to be at the pump twice a week. And my range for a full tank when doing 70 is mediocre (in the sense that I have like 30-40 miles remaining).
And from babying the dam thing for the past 10k miles, it would be nice to get at least 30 MPGs when doing 70 MPH, constant.
There are many factors that impact mpg. Your driving style is but one component, I recommend you read up on "hyper-miling techniques". Interesting stuff. You might find there are things you're doing that hurt mpg instead of improve it.
If your goal is to maximize mpg, here are a just few tips: Slow down! 70 is too fast for max mpg in your car. air resistance increases as speed increases. That means increasingly more engine effort is required to achieve and maintain those higher speeds, which means more fuel consumption, not less. And if you slow down from 70 to 55-60 you might even reach your coveted 30 mpg avg just by itself. Skip the instanteous mpg stuff, that tells you nothing about average mpg. You probably don't realize but many trucks have speed limiters (governors), many as low as 60 or 65 mph, so I don't buy your argument you must speed up because everyone abuses you if you don't. Very simple solution, simply grow thicker skin and drive the speed you want, and don't worry so much about douches or them tailgating. they rear end you, they pay. the only exception is if you drive slow in the passing lanes. Do that and you'd be a douche. At 55-60, you'll probably probably still be passing governed fleet trucks, and elderly speed vigilantees. And yes, of course people are gonna complain and honk and flip you off until they get around you not matter what your speed is, (you described pretty much every driver in NJ by the way) So why not simply smile back, and make 'em even more annoyed and let 'em pass you. Doesn't matter what they think and they're not paying for your gas.
Next, check your air pressure regularly. Underinflation is a mileage killer. Perhaps for your next set of tires, consider asking your parents tolook at ones with a lower rolling resistance. May not handle quite as nimbly, but then again you're driving a friggin' SUV on a highway, not a sports car on a race track. Think about it. Next, get rid of excess weight. weight hurts mpg. Make sure your filters are clean, especially the air filter. Remove roof racks, aftermarket spoilers or other kiddie add-ons that look cool to kids but cause drag. Coast to slow down instead of braking whenever practical, which also means no more tailgating, something young males frequently do but won't admit. You could also fold in the passenger side mirror. Believe it or not, outside mirrors cause drag and that hurts gas mileage, especially larger ones.
I think you should be happy with 28 mpg at 70 out a Rogue, which I think is awd, right? That's pretty darn good, especially for a young, inexperienced driver like you in an vehicle as aerodynamic as a cinder block. But I'm calling shens on your Nissan anger if its based only on your Rogue. I believe you even acknowledged it has been reliable. Nissan dealers are a different story. There are good and bad ones, the trick is only use the good ones. That requires some research, and it sounds like you and/or your parents may not have done, at least enough. But ultimately, If you really despise the car that much, perhaps you should give it back to your parents and buy what you really want.
To answer your question about 4 cyl engines being more fuel efficient than V6/V8. In many cases they are, but that applies if you're comparing identical vehicles except for engine choice. You'll find that's not necessarily the case when comparing different vehicles, due to so many variables, like the stuff mentioned earlier, plus adding a bunch of other stuff including (but not limited to) gearing, transmission, type of engine (diesel,gas, hybrid, hydrogen, n.a., turbo or supercharging,) size of the engine , tuning, weight of the vehicle, options, aerodynamics, etc etc.
One last note, most factory built-in car Nav systems suck. Though I kinda like the Audi sat nav. I remember getting in a then new S5 at VIR and turned on the nav system in the paddock for giggles and the track map appeared!!! Kinda cool. I didn't actually use it on track, but I'm wondering if that female voice would've said " turn right in 1000 feet".
. I guess the bigger question is why would anyone use an oem car nav system at all when there's a better one in just about every cell phones? Oh well. that's my Andy Rooney moment (baby boomer reference)
Hope that gives some perspective.
