Nissan VS FIT
I have a plan to get 41 MPG. I'm going to go head to head againts my managers 2007 Honda Fit. My 1996 Nissan Sentra 1.6 Ltr. Disconnect the A/C and make all four tires doughnuts. Currently he is only beeting me by about 1 mile per gallon Hwy. He gets 37. What do you think? I'll stay @ 55 so not to blow the tires.

My '93 Sentra Xe got a best of 49.97mpg with a slight bleed of propane into the engine via propane injector. Most of the time the 1.6 would hit 37-39 all day long. My recently acquired 02 Sentra XE hits 41 almost every trip I make to work and back (30 miles) If you are running 55mph, it should be doable. Had you played with any mixtures of acetone in your tank? I say this because my 200mile acetone (2oz per 10 gal) test today bumped my mpg average up to 38 for a 200 mile trip 75-80mph.

I don't think the donuts will help that much, but you can try.

Nice MPGs on the XE. Have to do some searching on Propaine. I'm getting ready to use acetone soon. 2 oz per 10 gallons sounds about right. Not sure if this additive needs any cleaning or dewatering. Sounds like you rigged up some type of real time MPG device. Older cars dont have that standard and my newer car is always 10% off. Combined with the way the most gas pump is rigged to give you 5% less gas than you pay for, most people are pritty happy with the MPGs they think they are getting. This is my wifes car and she only puts 90 miles a week on it compaired to my 550 w/rideshare. Greasin an old Diesel Mercedes was the only way to get uncomprehendable MPGs for me. Lot of work, so life seems to be on the back burner durring tis qwest.

SVO you dont sound like you know the answer to my question of four donut tires for a fact. People on this very forum are considering windage and here we are talking about friciton with less of a tire footprint so less drag to gain MPGs. You may not have considded that and on top of that, if these tires are smaller than a normal tire the distance on the odometer will increase. Right? I know when I get a flat on my 2006 Dodge Grand Caravan SXT, if its on the front tire my MPGs go up from 19 to 23 HWY mpg. People have to speed up and notify me every time this happens-somehow the ride and steering-feel is unaffected by flats. Better than flipping it off the road and and having insurance detectives let you know what happend as your sitting in your body cast.

You'll win easy. I had a 91 SER that easily got 34-36mpg definitely not trying. I recommend a new O2 sensor if its over 100k. And clean the MAF. These are my nissan tricks. The donuts will help if you get the proper height, if there shorter it might not work. Remember that most donuts are rated for under 1000 miles some only 200. The tread compounds are very cheap and not all that safe to drive on.
Good luck.

Hi,
You both can do better -- either car should be able to get 40-45mpg without much effort.
Go for aero mods if you do some highway driving, and just pump up your current tires to somewhere near or at the sidewall pressure. Drive like you don't have brakes (but of course, please use them if you need to).

If you guys are calculating MPG off your odometers then just put the smallest diameter tires on that will keep you from scraping too much and you'll win hands down unless he figures out why.

Thanks for the tips guys,
new O2 sensor, clean the MAF, 2 oz Acetone.
Aero mods are not for me. I'm too cheap-cars too old. How about wax?
Do OEM hub caps help or not?
