I was driving back home tonight and just filled up (premium 98 always) I reset all trip displays just like everytime I fill up
Decided to set the Screen to INST Fuel, Cruising long, fine, but when I pull up to the lights I noticed my Inst fuel per litre was going up until i come to complete stop, where is hit 0.0l/100km
I owned and driven many other Commodores, but have never noticed this to happen, and it not something I usually do
but Is it normal for the display to this on the 3 stage dash as I pull up, or is it actually chewing up juice by hitting the brakes
Well think about it, if you were to crawl along at 5kph for 100k's you're engine would still be using fuel, and it would take you...just let me calculate it...25 years.
So of course it will use heaps of fuel PER 100k's when you are barely moving.
On newer models it changes to L/hr when you are going under a certain speed
ahhhhh ok, its the first time I have ever noticed it, It just gave me shock,
I mean I know my Gearbox is on it last legs and I thought it had something to with selection of downshifted gears preparing for rolling start....
Whilst the above makes sense, I don't think either of my VR's do that... I'll have to check... pretty sure fuel drops a lot.
What sort of numbers is it climbing to?
my old vs v6 calais did this, my adventra does is too, when under brakes with the torque converter holding the revs. I have noticed that if you are moving with not acceleration, under brakes, in neutral, the computer still does it. Dunno why.
Like wise Philithy,
sittin on about 9.8 cruising along, ease off it - 8 - 7 - 6.7 - 5.1 - 4.4 - 3.6 - 2.2 then 15 - 28 - 39 - 51 and 0.
I tried it today, yes it went up, but only til 9. something... ;\
(I shift down in an auto btw - May effect results)
shifting down as in using your trans to slow you down?
if so, dont expect the trans to last too long, they dont seem to like that treatment verymuch
Its crazy, not to mention the damage to box it self,
Its something like the pressure on the Diff, Driveshaft and Box and Flywheel is astronomical
Think of it this way - Compression Braking "as its called" obviously needs pressure
Pressure to motor, puts pressure to the box, which causing the shaft to TWIST if to much pressure and then lastly the kick back on your CV's and Diff
OzJD im affraid to say - Manuals are manuals and alot of those in sydney all drive around with a DIFF Technics sticker on the back for this exact reason - New Diff some were a long the line
Auto's are Auto's - they do all the hard work for you, treat them right - they will treat you right
ill 10000000000000000th the jumping up in fuel when slowing down ive seen in go up to 80s good fuel economy going slow:P

Brake pads are cheaper than a new gearbox..
