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 :)

shame that rail i pulled off it is a passenger rail. might just flog it.

+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...

      V37 Radiator removal

      By Duncan · Posted

      So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You don't need to drain the intake heat exchanger to remove the radiator but depending on your plans you may need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic

      If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
