if you're not labouring it, use 5th

ive gone back to that in my fourby, gets me an extra 100km out of a tank easy just doing that

+1. I'm almost always in 5th at 60 km/h and and when it's flat I often go through 50 Km/h zones in 5th too. :)

if i try to use 5th at 60kmh, the car nearly stalls....

1st = 0-96km/h

2nd = 133km/h

3rd = 175km/h

4th = 205km/h

5th = 2xxkm/h

Factors Affecting Fuel Economy

Fuel economy is affected by a vehicle's size, weight, aerodynamics, fuel delivery system, engine type and transmission type. These values remain constant for a specific vehicle.

There also are many variable factors. As mentioned, the heating value of the petrol is one. In addition, fuel economy is affected by weather conditions, air conditioner use, road conditions, the route driven, driving speed and driving style. And it is affected by the mechanical condition of the car - engine tune, wheel alignment and tyre pressure. Some of these non-petrol factors have the potential to cause substantial changes in fuel economy. The table below shows a list of average and maximum effects published by the United States Environmental Protection Agency (EPA).

Winter-related factors can combine to lower fuel economy 20% compared to the summer. Rain or snow on the road offers more resistance to the tires. It may also require the driver to slow for safety to a less fuel-efficient speed. In cold weather, a richer air-fuel mixture is required to start and warmup the engine. And much of the warmup is done at idle because of the need to defog or defrost the windows. Also, in many vehicles, the air conditioner is operated to assist defogging. More energy is required to overcome the resistance created by the higher viscosities of cold lubricants - engine oil, transmission fluid, and differential lubricant.

Short trips are worse for fuel economy than long trips because a cold engine uses more fuel than a warm engine and because of the energy required to overcome the resistance of cold lubricants. Traffic jams and bumper-to-bumper driving also extract a heavy toll on fuel economy.

Conclusion

We don’t think any of the points made in this article are groundbreaking. Bluntly, they are not. But if you select the car carefully on the basis of the real needs it must satisfy, keep it well maintained and drive it well, you will be getting the best fuel economy possible in your driving circumstances.

No shit! :)

that article doesn't mention the use of 5th gear at 60-65 km/h....

uhm... fuel consumption isnt directly effected by revs, load has more of effect.

Revs has something to do it for sure, the lease cars i used to get with the trip meters in them that show instant fuel usage backs that up, driving down heaslip road doing 90 it'd be showing me using more fuel in 4th at higher revs then 5th in lower revs...But Steve has also hit the nail on the head with that post he's put up sums it all up really

Was walking down hindley around 3am this morning. I see the undercovers 4wd, cops jump out to help with this fight. One guy who was involved in the fight runs off towards me and 5 cops chase after him down hindley. My mate kicks the guy in the leg, slows him down abit, cops still chasing him, tackle him from behind and the guy goes straight to the ground. Everyone cheers.

Was fun to watch this guy get decked.

Thats my exciting night :(

LAWL i saw that i was crossing the road all the cops ran out the 4wd n ran past me n ma mate haha i thought someone cleaned the guy up be4 the cops did becoz everyone was clapping n cheering hahaha oh god it was funny!!

epic fail for the guy fleeing the scene :)

+1, my old man told me that 5th should be reserved for anything over 80, and that goes for the majority of cars

you need a certain amount of revs to cycle the oil system to the required pressure, I would never drive 60kph in 5th unless it was downhill (in which case the drivetrain is not under load)... the gear ratios in a GTR are quite nice imho, I wouldnt want to change the ratios for a daily driven car... on my weekend hills run, i very rarely used 5th gear and the fastest we went was 115kph, so I kept it in 4th for most of the way, and the entire 2 hour run took just a tad over a quarter tank... most of the time the car was in 3rd doing 4000rpm around corners, so I wasn't being gentle, and yet it took much less fuel than I estimated

yeah RB20 isn't too fond of doing 50k in 5th, will just handle 60 aslong as there isnt any hills or sudden accelleration required, but 4th fits the bill fine, even 80 in 4th sits fine. Will be interestering to compare the new 25/25 engine/gearbox combo...

      Lock up the old for sale / wtb threads.

      By MBS206 · Posted

      Hey Prank, Any chance you could easily lock all the old FS and WTB posts? Even if it's just a one off hit through there. The majority of posts are people asking someone if they still have something for sale from 8+ years ago, when the person who originally advertised it hasn't been on the site in donkeys years. Just a thought I had. Maybe go through and lock everything older than 12 months or something?

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      I'd be thinking it's the other way around. Less of an impact when rich compared to lean, but definitely in a lean condition the cat specifically uses up a lot more free oxygen. When rich it's grabbing oxygen from other places to like NOx, but it still gets converted to CO2 and H2O.

      By Kinkstaah · Posted

      Sorry yeah - My post was a mess and I attempted to fix it. In my example both sensors are post-cat. I realized later that I had literally pulled the motor apart and we saw no evidence of any knock and everything was sweet, so my WB was likely accurate (enough!, if anything the engine looked a little rich) In your example I'd want to recalibrate both sensors. I realize this is not possible in the real world. Best you can do is: 1) Calibrate current sensor 2) Calibrate a brand new sensor in same location (do you have an older one to compare to? Or is this a new purchase) Observe any changes in readings. I always thought it was 1M, I am clearly out of date. Mine is likely 2m+. I didn't want to have to choose one bank over another in my application.
