Overdrive is like an extra gear for the auto that was designed this way to reduce fuel consumption on the highway the main reason that people leave it turned off in town is because you need to get to between 80 or 90 kph before overdrive kicks in!

And if you cruise at around 80 - 90k's (mine changes as low as 70kph sometimes) the overdrive can change in and out of gear (rather unecessary at this speed) and this constant changing between 3rd gear and overdrive severly wears out the overdrive!

P.s PVA-glue towing a trailer or having two chicks in the car is not a good reason to use the overdrive! (and you wouldn't benifit nothing from it unless you were doing more than 80 - 90 k's) maybe your thinking of the power button (this changes the rev range at which the auto changes gear (redline gear changes if under heavy acceleration) and also early drop-down which can be quite fun! The hold button just makes it so that under hard acceleration the auto won't drop-down a gear!

Exactly right....I was going to type something along those lines but I couldn't be stuffed. :D

but i still dont' see why people would want to drive with it off .. i mean the revs are much higher ... maybe about 600rpm or something like that which is really noticeable ... which means you could stay at the same speed at a lower rev and therefore be more feul efficent ... so why the recommendation to drive with it on around town?? i only ever turn it off if i want to go a bit faster.

Read this. Posted just above by MegaGTS4.

ok i will do a test ... i have to fill her up today anyways .. i will use my normal petrol as i always do and i get around 450 - 500 depending how i drive ... i will always use overdrive off when in normal traffic ... say anything below 80kmhr and turn it on anything over ... i will give u guys the results in say 5 days time which is the time it usually takes for me to use a whole tank.

oh another thing ... can u guys with auto gtst's tell me what rev u change gear at for each gear with overdrive off??

PLEASE PAY ATTENTION!!!

Having overdrive turned on or off will make no difference to shift points, fuel economy or power BELOW 80 kmh. If you are driving in an 80 k limit, or below, leave it off, as on and around 80 k it will be cutting in and out and will premarturely wear out clutch packs in a transmission. My O/D is always off, unless im travelling at 90 k or more....

The power buttong is the one thats will change shifts points, and the only thing that changes ratios is the torque converter because it actually can give you a 2:1 ratio in torque multiplication.....

    • Price seems pretty good to me. Also seems a hell of a lot cheaper then buying another vehicle that only ever gets used for towing.  I'm a long way from you mate, I'm a couple of hours out of Brizzy. 
    • New [400]Z, they're available in manual and you don't have to worry about parts scarcity. 
    • Just planning to have the wiring neat and hide as much as possible.
    • The sodium acetate, mixed with citric acid, doesn't actually buffer each other. Interestingly though, if you used Sodium Acetate, and acetic acid, THAT becomes a buffer solution. Additionally, a weak acid that can attack a metal, is still a weak acid that can attack a metal. If you don't neutralise it, and wash it off, it's going to be able to keep attacking. It works the same way when battery acid dries, get that stuff somewhere, and then it gets wet, and off it goes again breaking things down. There's a reason why people prefer a weak acid, and it's because they want TIME to be able to be on their side. IE, DIY guys are happy to leave some mild steel in vinegar for 24 hours to get mill scale off. However, if you want to do it chemically in industry, you grab the muriatic acid. If you want to do it quicker at home, go for the acetic acid if you don't want muriatic around. At the end of the day, look at the above thumbnail, as it proves what I said in the earlier post, you can clean that fuel tank up all you want with the solution, but the rust that has now been removed was once the metal of the fuel tank. So how thin in spots is your fuel tank getting? If the magazine on the left, is the actual same magazine as on the right, you'll notice it even introduces more holes... Well, rust removal in general actually does that. The fuel tank isn't very thick. So, I'll state again, look to replace the tank, replace the fuel hanger, and pump, work out how the rust and shit is making it past the fuel filter, and getting into the injectors. That is the real problem. If the fuel filter were doing its job, the injectors wouldn't be blocked.
    • Despite having minimal clothing because of the hot weather right now, I did have rubber gloves and safety glasses on just in-case for most of the time. Yes, I was scrubbing with my gloves on before, but brushing with a brush removes the remaining rust. To neutralize, I was thinking distilled water and baking soda, or do you think that would be overkill?
