I was just curious if there are any hypermilers with fronty's? If so what kind of of mpg's can u pull? I am mostly interested in 1st gen ka24de 5 spd as that is what i have. I wouldn't consider myself a big hypermiler altho I have a scangauge 2 and use some mild hypermiling techniques... My best is only around 25... I thought that I would do better as I heard some people have gotten 30...

I've tried the various tactics in my 2000 4cyl 5spd with no real luck, I typically average between 21.5 - 24mpg. The best I've done is 29.5mpg on one tank. To do that I drafted semis on totally flat roads at about 55mph on a long road trip.

Ya thats way more extreme than i get... i just do some coasting in nuetral, turn off engine at long red lights, shift at low rpms, and accelerate slowly... haven't taken it on a roadtrip yet tho

 

[mustard23]

I tailgate.. dose that count?

 

[4cylman]

only if u do it to semis

 

[mustard23]

no they are smart enough to stay out of the fast lane..

I read coasting in neutral uses more fuel then just coasting in gear. Supposedly if you coast in gear above a certain RPMs the injectors cut off until they reach a certain point where the IACV and the injectors open up to keep the engine running.

I seem to feel a slight "blip" at ~1700 RPMs. Then I down shift and feel it again. Again I haven't noticed any improvement doing this.

BTW. I don't draft semis normally, I just tried it once on a long trip. Typically I can't stand tailgators, especially when I am in the right lane or already stuck behind someone else. I either slow down, make my brake lights flash constantly, give them a wiper shower (if its a nice clean car), and maybe an abrupt tire chirping downshift for the worst of the worst.

I also carry a camera for those that are too special to read residential speed limit signs or right turn only signs (drive straight thru instead). It is awesome when they catch me taking their picture and look at me like "what did I do"? If only I could report them to their insurance company with some videos....

coasting in gear is better if for only a short dist and your rpms are above 1700 rpms or so when the injectors open back up... in nuetral you can coast for a much longer dist and do it on hills and such whereas leaving it in gear will slow you down much faster... and downshifting is not a recommended for higher mpgs... it also wears your clutch out faster...

like i said i don't draft semis either... that is extreme hypermiling and a good way to get yourself killed if they have a blowout... and i agree that tailgating is for a$3holes unless the person is interfering with some good coasting I have going ;0

If you're only getting 25 mpg when hypermiling you probably need a tune up. Expect ~$100 in parts for a good engine tune up. I ordered all my parts from Rockauto.com for under $75. This included an Air filter, Fuel filter, Spark plugs, Wire set, Distributor cap, Rotor, and PCV valve.

I also changed the engine oil to Pennzoil platinum 5w30 synthetic. I drained and filled the rear diff with Amsoil 75w90 Synthetic GL5 and the transmission with Amsoil 80w90 GL4 Synthetic. The transmission definitely shifts a lot smoother with the amsoil fill. I don't have any grinds between shifts, which I had with the stock Nissan fill on cold mornings.

I consistently get 28-30 mpg. I drive about 70% highway 30% city. The single best thing I got for increasing my mileage was a ScanGauge II which is incredibly useful not only for monitoring mileage, but for scanning for codes, checking various engine vitals, and having a great trip meter function. I also just put an awesome horsepower program on it.

I get 25 mpg in mixed driving, like clockwork. 28 to 30 on the hwy at 65 to 70 mph. No special tricks, I use 5w30 Walmart oil (which, by the way, is nice clean oil).

 

[SDFrontier85]

I'm not a hypermiler but I do try to get good mileage. On my fill-up today I got just under 20, all city hitting every light red the whole tank. I can only imagine the mileage if my luck would change with the lights. lol

I average 20mpg on a tank driving it like I stole it.

 

[lane.mcpeak]

I average 20 no matter what I do

Hmmmm... well i haven't done a road trip since i got my truck so all my driving is mixed at right around 25 mpg... i wonder if doing all that tune up stuff would help... i'd hate to spend the money and not get any higher mpg's... prob just do stuff as needed... i only have about 40k mi on it

Man, you have an '04 with only 40K on it? I have an '02 with about 97K on it. Granted I bought it with 60K on it already, and drove to Cali from Oklahoma once, and have been to Illinois and back twice, and Kansas.....

Will you explain hypermiling though? Is that just putting it in neutral when you can coast w/out losing much speed, and not speeding like a bat out of hell?

 

[4cylman]

hypermiling is a combo of numerous driving techniques in an attempt to net you the highest gas mileage that your vehicle is capable of getting... yes coasting and not speeding are a couple of the techniques... turning your engine off at long red lights (idling kills mpg)... bumping up the psi's on your tires... accelerating slowly and shifting at low rpm's... running a lighter weight synthetic oil... using cruise control...

there are many others and it is basically what u make of it... these examples are some of the things i do and would be regarded as mild... some people go extreme and draft semi's on the freeway (not me)... its definitely not for everyone tho... i used to drive really fast and challenge myself on how good of time i could make (lots of speeding tickets)... now i shoot for my best tank mpg... i figure money is tight so why spend more of it on gas than i have too

 

[lane.mcpeak]

I guess I'm a mild hypermiler myself. I almost never shift above 2,000 rpm. I can tell when the people behind me don't like it, but whatev. I coast in neutral up to red lights from as far away as possible. I don't usually speed either. I keep my tires at suggested psi though.... about 38. I run 5w30 oil.... but that's factory right?....so, yeah, just the mild stuff.

 

[4cylman]

Yep - sounds like it... from what I understand 20 mpg is pretty good for the V6's

Average or just city? I'm getting almost 20 city.

remember he's got a 4 cyl
