Car Forum / Nissan / Nissan Cars / August 2005My Sentra makes 40+mpg!!!!
As I stated previously my 2004 Sentra makes 40+mpg highway and 36+ moderate city/highway mix and still veor 30 heavy city. I spend so little on gas and feel so good about not polluting air (=CANCER). The reason is basic: REDUCTION in weight + driving habits. All nonessential is removed, also wheel rims are lightweight/strong aluminum (TSW, UK/German aluminum alloy->reduces unspring weight, very important for better acceleration/braking). Even to extreme: removed spare tire/wheel/jack/wrench as I am covered by 2-year roadside assistance (free for a new car) and would take only to a long-distance/wilderness trip where assistance would have problems finding me and replacing a flat tire if any happens. I removed big things (one seat, 2 remaining is enough) and small things (passenger sunvisor, HECK I MIGHT REMOVE DRIVER"S sunvisor as I never suffer form sunglare for too long). Sentra is one example, any small/well-designed car can make.it. My more importnat point is not really gas prices but pollution. This Sentra is PZEV (PARTIALLY ZERO-EMISSIONS VEHICLE) and emissions level is life-time warranted, you dont need to read manufacturer's claims - just run the engine and check what;s coming out of tailpipe: WARM AIR, NO SMELL, it's such a difference form my old Oldsmobile Cutlass supremem you could smell a block away. Tjis smell is not just smell, it's CANCEROUS (gas is carcerogenic I hope you all know, exhaust is even worse, especially diesel). Clean exhaust, when idle little different from warm air like no fuel is even burning, of course it's burning... still I am feel good about myself and most important about mine and YOUR children. Now FULK ALL THE SUV'S AND THEIR OWNERS!! I have not gone to these extremes but my '94 Sentra gets 36 MPG, and has 240,800 miles on it. Part of economizing is not replacing a car before it's worn out, since there is energy involved in making the steel, iron, aluminum, glass and plastic in the vehicle.

Why not empty the windshield fluid reservoir, and pull out the carpet, remove the radio, throw out the glove box door, and door panels while you are at it!

Part of economizing is not replacing a car before [quoted text clipped - 33 lines] >> >> Now FULK ALL THE SUV'S AND THEIR OWNERS!! Which I did!! I emptied windshield/washing liquid, pulled out stuipid artifical heavy mats and replaced with 100% natural cotton bath towels (one cut in two pieces), glovebox door stays in as it prevents plastic/cancer smeel from escaping from inside gloveb ox and it also in-cabion air fileter is mounted on it! Radio I need I was wondering how much difference the weight makes. I have a '2000 Primera Estate Sport+. (That's a 2 litre, gasoline fuelled, 150BHP for those of you Over There). It's got a natty trip computer which tells me how many MPG i've got since I last reset it. With an annoying 10% overread but I can cope with that... Last weekend I filled the back to roof level with cuttings from the garden, probably a quarter ton or so, intending to drop them off at the tip on the way home from work. With this thread in mind I reset the trip meter before driving my usual route. MPG was pretty much what I usually get. If it was different, it was less than 5% which is quite in the normal range. Now I'm certain that weight makes a difference - but it doesn't seem to be that much. My last 1.6 hatchback used to get 40+MPG (Imperial gallons, not US; they are 4.5 litres). This one averages maybe 36 when I concentrate, and can dip way below that if I'm stuck in traffic or start using the power. I think careful driving is worth 25%; weight savings 5%; and choice of car... the difference between 60 and 16 MPG. Andy It takes energy to accelerate weight, it doesn't take energy to move weight at constant speed once it was accelerated to that speed, basic physics law discovered by your countryman Isaac Newton (who was also part jewish) except for friction but frcition is not much different with or without weight you described. So if you get similar fuel economy with or without the kind of load you described, you're a good driver, it means you accelerate and brake moderately and not like a 16-year old ape. It is during acceleration when fuel is sucked in at high rate. ALSO DRIVING AT 55+MPH DROPS FUEL ECONOMY DRAMATICALLY ffor two reasons: aerodynamic resistance increases too much, and due to engine/computer controllers design. So you must be a reasonably good driver not to lose miles with such loads. Now try to haul several hundred kilograms and hard-accelrate and see what happens, you lose fuel What major repairs have you made with 240K miles is it an automatic trans?

The most costly repair in terms of dollar was new Front Shafts - about $461 back at 144,000 miles, a little over 4 years ago. I have owned it since May 19, 1997 when I bought it with 52,200 miles on it. Repairs have totaled $1,946, preventive or regular maintenance $2,759 (including tires) and fuel costs have been $7,343. I track everything in a program to record gasoline, repairs, maintenance, additions, etc. The only cost of ownership not included above is insurance and the cost of purchasing the car. It works out to about $0.05 per mile to operate.

And you probably putt along at 40 km per hr too on a long winding road with no stops and traffic to get that kind of mileage. It's not realistic and practical, no car actually gets the posted mpg. They are not tested under normal conditions. Peter > It is a manual transmission. > [quoted text clipped - 53 lines] >>>> >>>> Now FULK ALL THE SUV'S AND THEIR OWNERS!! What a joke! I drive at 65-70 mph (105-110 kph) on an interstate highway (I-75). On my commute I have only about 5 miles of 38 that is city driving. All else is highway but includes stop and go traffic on I-75 at the evening rush hour. Early morning there is no congestion. I don't have a clue what the rated MPG was for this vehicle, all I know is what I get.

I'm currently using 'Automotive Wolf'. It has its good points and its bad. Aways looking for somthing better. BTW i am also running about a nickel a mile at about 43k miles a year. OH, i do not include my tool expenses, unless that tool stays in the car, at all times. If the tool stay in the shop, it is not included.  SignatureThrockmorton P. Ruddygore Also, find tires that say they will take 60 psi and run them at 60 psi. My standard 2001 Sentra now gets 33 mpg. The strange part is that until it went over 55,000 miles, it consistantly got 29 mpg. Hats off to your "green thinking" Sandra... but isn't making a soap-box racer out of your car a bit extreme...

Mike Kojima, a Nissan guru, reported in an article for Sports Compact Car Magazine he got 40 mpg on a B14 1.6 litre Sentra (1995-1999). The mileage improvement was achieved installing high quality cold air intake, header and exhaust. A freer flowing intake and exhaust, without forgetting a complete tuneup, can make that mileage possible without going to extreme weight reduction measures.
