Ok,

So yesterday I got my 6 Strand Grounding system fitted and drove the car last night with no apparent difference that I could note.

Today I had to drive to brisbane about 190km round trip and did what I normally do which is reset the trip calcs to work out fuel consumption.

Well was I astonished, it returned 7.1 lt per 100km now the best I ever had on this trip which i do like 3 times a week is 8.9 lt per 100km. This was at a speed set on cruise at 120kph at 20c temp.

Now I can only assume that something with my previous engine ground must have been seriously astray to have such a differnce.

 

That all sounds good but I can't get a real feel for the improvement b/c i'm too lazy to break out my calculator and and convert the metric into english. Anyone else here feel ambitious and want to take this homework assignment on?

 

100km is roughly 62 miles

7.1 liters is about 1.6 gallons

So what he is saying is he got 38 3/4 a mile for each gallon, which is actually unbelivable!!!!!!!!!!!!!!

The car standard gets about 28 miles to the gallon highway so he's getting an additional 10 miles per gallon highway or 200 miles per tank full range,,,

Thats great Black --- with gas prices the way they are thats awesome

 

Your right that is hard to believe. Any one else get this result with a grounding system?

 

You can't get 38MPG, that is impossible in a Maxima. If you somehow put the VW TDI engine in it, it still probably wouldn't get 38mpg because of its weight.

 

Maybe the fuel is different there, or maybe he drove downhill the whole way. I have gotten in the low 30's on short highway trips going about 70 mph, but its reeeeeaaally hard to do.

 

38 mpg seems to unrealistic to me. I could believe a few mpg increase. There must be another variable involved.

 

Hey Deus, I think those wheels look pimp on your max.

 

The only way you're going to get 38MPG is if you go downhill with a tailwind.

 

My reading went up close to 2 MPG per tank for normal commute (22.8-9 mpg currently, no heavy traffic) since I installed my grounding kit. I can see you get that kind of improvement on a long trip since you upgraded your exhaust system too, and if you drove at a constant speed with little traffic. Since you do this drive regulary, keep watch next time.

Last week, 250 miles drive from Las Vegas, I used less than 1/2 of a tank, which is about 34 MPG (guesstimated). My average speed was about 80-85 MPH, temp was about 85F (at night). I have intake and custom exhaust piping.

For those of you who raised the BS flag, go try it yourself. The key is constant highway speed for a good distance, regardless of ground kit or exhaust, though they help.

 

I don't know about improvments in MPG but an earlier thread with the grounding wires stated improved their eletronics(window motors etc...) were more efficient-running more smoother and faster.Now if this mod improves gas mileage-we should all jump on it.Last fill up in BX,NY $3.479 a gallon-yikes.Anybody in the States seen these improvements in MPG?

 

Actually, I probably should have checked the math, 7.1 liters = approx. 1.875 gallons...So he actually got about 33 mpg. Which is a 5 mpg increase over EPA estimated Hwy 28 mpg. He also said it was about 20 deg C or 68 deg F. 33 mpg is a little more feasible number for the given temperature.

 

33MPG would still be extremely hard to get even if you were driving over terrain that was slightly downhill and there was a strong tailwind. Until I see some others do this and see big improvements, I wont' believe it.

 

He could also have started his calculations while already at cruising speed. This (hypothetically, I'm not pointing any fingers) would be misleading because it does not account for acceleration to cruising speed and any city driving at beginning and end destination.

 

The amt of gas used to get up to cruising speed is minimal and not significant if you use the rest of the tank going a constant speed on the freeway. In other words, over the course of the tank when driving on the freeway, the 5-10mpg you get when accelerating becomes irrelevent.

 

If you went down 1 km of elevation for 190km of driving and had like a 25-30mph tailwind, I can see 33MPG.

 

AND don't forget the city driving before and after. I am going to guess that his destination wasn't directly on the highway along with his house.

 

Foobeca, I see you drive a 5th gen manual trans. I'm getting better MPG on my 6th gen auto than I did my 5th gen auto, close to 50 more miles per tank w/ similar car setup and same commuting route. You might say 6th gen has 20 gallon tank, but I can tell you that from "empty" fo full, I've never pumped more than 16-17 gallons, about the same as my 5th gen. 33+MPG is easily achiveable with 6th gen on relatively flat highway drive at steady speed, here Blackpaladin is talking about 110+ miles roundtrip.

 

I don't believe you can consistantly get 33mpg, maybe 30, but not 33. The 5th gen 5spd sucks @ss for gas mileage because of it's $hitty @ss gearing. Nissan made the gearing aggressive in the 4th and 5th gen to make the car seem more powerful that it really was.

That's why the auto got better gas mileage. 3300rpm @ 80mph in 5th gear is rediculous. Even my lowly 96 altima 5spd had a taller 5th gear.

 

In answer :

Remeber my max is like Nearly 180kg lighter then your maxs with the mods and from stock .
The Reset button was hit just after start up and mind you is like 1 minute from my house to the exit/entrance ramp to the highway.
Nomal lite-medium traffic on highway.
I was using our 98 octane fuel your 94 i think the only fuel i use .Full tank.
I have a full exhaust and intake mods.


I used to get 6.5 on my old AMG 1.8 Supercharged Merc and that was a 4 cyc so I thought for the this big bus the numbers were pretty good.

 

I used to get about 370-380 miles per tank w/ my 5th gen, now I'm getting about 420 to 430 miles, no BS. 5AT on 6th gen does 85mph @ 3k rpm, don't know about 6MT. I believe Blackpaladin's is a 4AT, don't know ratio. All I can say is that from my own experience, I believe him.

 

This tells me that you have a light foot. I usually get the MB 1.8 Kompressor for a loaner, when I get my other car service, I never got better than 20MPG, that's about 8.5!? Then again, they were loaners .

 

I'm sure that the 5th gen 5spd has the worst gas mileage than any of the 4th gens, 5.5gen, and 6th gen. I just don't believe that one can get 33mpg in any maxima. I can see 30mpg in a 5spd auto or 6spd man, but not 33.

I'm at 440miles on my tank right now w/85% FW and 15% city. I'm gonna fillup after work today. I found that if I keep my FW speed at 75MPH and accelerate gently in the city, I can get about 27mpg w/ a 85/15 mix of driving. Before, I used to drive it like I stole it and would drive 90mph on the freeway and get 23-25mpg.

 

What did you do to reduce 180kg (400lb) of weight? You must have almost totally stripped that maxima to achieve that. It would basically have to be 4 wheels, an engine, a seat, and a steering wheel to achive that.

I just don't believe that one can get 33mpg in any maxima. I can see 30mpg in a 5spd auto or 6spd man, but not 33.

I can only report what the little calculator tells me .. I will give it a week and then get back to you on what a tank gives me . I was getting like 720km +- 20 out of a 70 lt tank without the mods so lets see what we get now.

Anyhow I think we strayed a bit , for the price of the mod (less then $100) I reccon everbody should get one , it plainly is helping in some serious manner with the economy anyhow.

 

LOL.. our Maxs are lighter then Altima's ....to start with ...then I ditched the Complete exhaust system and replaced it gear that was a least 10-15kg less.

 

autos.msn.com says the maxima SE w/5spd auto is 3473lbs and the altima 3.5SE auto is 3274.

 

He has an Aussie Max, that's how he's lighter.

 

My Maxima gets about 23 MPG, I must have a gas guzzler

 

3224 stock ....LOL

 

yeah, the skinny basterds don't eat much

I wonder if some guys run slower at the track b/c they live off Mickey-D's

I removed my spare, that's a good deal of weight. used a styrofoam box form Omaha steaks to support the carpet. I keep my emergency cleaning supplies in the well too.
I figure the solid RSB added some weight but I'm still minus. while gas is tough, I'm trying to stay below 1/2 a tank to reduce weight too.

maybe one day I'll mod just to get lighter parts. Those Nismo wheels on the Nissan site for the Alti are our exact size and a lot lighter. but $450 a piece?


I made a grounding kit, but the wires were dull and look pink. Now to order some more and make another one. only if AT had red to begin w/ and gold terminals. I may break even making a second kit.... which will of course add more weight.

 

[QUOTE=NismoMax80]yeah, the skinny basterds don't eat much

Nah .. I'm a Fat Bastaard ...

Needed a light car cause I'm 102kg...

Heaps of universal kits around with good copper wire , that's the way I went.

 

What's so different about a max down under that it's 250lbs lighter?

 

Exactly...He didn't say he has been achieving those results consistantly, just for the last 190 km trip he made. And just like he stated, there are other variables involved: higher octane, reduced weight, etc.

it's a completely different car. look up Teana

edit:
how much capacity is your tank? please convert for us lazy stubborn Americans if it's less than 20, hat's some weight right there. I bet your overall size is smaller. also too lazy (it's friday) to look up our measurements.

 

Have you seen a "max down under?" Have a look yourself. It states even the heaviest Ti-L weighs 1480kg or 3263lbs.

best i ever got was 30mpg with a picture taken on my road trip to canada and somewhere on my PC i do have a picture

 

That is a lot different. I just assumed the maxima there would be more or less the same as it is in the US.

 

I think we have strayed from the point...

which was I fitted this little ol Grounding kit and it went from 8.9 down to 7.1 lts per 100km ..So me thinks it works somehow and works well .. or there was a serious problem with the grounding on my particular vehicle. :attention

18.49 Gallons US = 70 litres
