I have just bought a 2005 T/D auto with 29500kms on clock, first full tank of fuel with 300kms around town and the rest to Albany and back I got 12l/100km. It has Desert Duelers 275/65's fitted which I don't know if they are taller than standard to effect speedo accuracy I will have to check. I am keen find out about any mods for more power and economy.
Not sure if this thread is still alive and twitching so I'll post the question and see what happens... :|
I'm looking at getting a whole new exhaust for my 2004 3.0 Diesel 120 Prado. I went into the local exhaust shop here and the guy gave me a quote for a 2.75 inch Mercury exhaust system. $800 fitted. I don't know why he went for that one but he said they were pretty good for the money. I see there is a lot of info on this site about the Beaudesert setup, but is Mercury any good?
Thanks,
I have a april 2007 VX, My wife and i are sure something has changed when it comes to how much fuel shows what level on the gauge.
We have run 5 or 6 lots of 180L through the prado in the last 12 months and thought the gauge was pritty linear. But we are now seeing numbers like Blackbird's ( no the tank is not dinted now :-).
The weekend before last we put 30L in and it showed 1/2 on the last 90 tank when the light first came on. This weekend 100L after the low fuel light had been on for 40 km ( its a long way between BP stations when cutting wood in the bush here) showed 3/4 of the whole gauge , but after 10 minutes dropped to 1/2 of a whole gauge.
We get between 10.2 and 10.8 on the SGII averaged over a month.
2007 120 D4D VX Auto.
1985 LWB Suzuki Sierra 1600.
have just finished first tank on 08 D4D - very conservative driving
Rough figures (am yet to get exact speedo error) put economy around the 11.5 L/100km - Am a little disappointed but I do run 265/70 Cooper STs which i am presuming makes a big difference - out of curiousity at 100 km/h I am doing about 2100 revs - how does that compare to those with standard size tyres?
At first thought I had the quick reaction of "Im selling the STs and putting standard tyres back on" but having read through other PP reports - maybe a litte hasty!
Definately agree with the comments about the second tank going a lot quicker - At one stage I wanted to glue the little needle on so it stopped dropping so fast! :evil: - Is a lot more painful on a lease car knowing you have to keep driving it to get the kms up!
Hama, your right about the coopers, before I fitted them I was getting in the low 10's around town, now with the st's I'm averaging around 11.6 & on the hwy about 10.8

yetiboy - what % error for your speedo do u work on? - I reckon about 4% is about right going by a couple of GPS's I have tested with.
I found that when I am doing 110 by speedo - the GPS says Im doing about 106 - I thought it was meant to be the other way round?? how does that compare with you?
First of all , you will get a full 1 to 2 l/100km back by the time the motor is run in at 12,000 Km or so.
Now for the tyres:
--cooper tyre-------------------
Height of tyre wall = 265 * .7 = 185.5mm
1/2 of a 17" Rim = 8.5" = 216mm
Wheel radius = 216 + 185.5 = 401mm
Circumference = 2 * 3.1415 * R
= 2522mm per tyre rev.
= 396 revs per Km
-----------standard tyre---------------
Height of tyre wall = 265 * .65 = 172.3mm
1/2 of a 17" Rim = 8.5" = 216mm
Wheel radius = 216 + 172.3 = 388mm
Circumference = 2 * 3.1415 * R
= 2440mm per tyre rev.
= 409 revs per Km
401/388 = 103.4 ( the cooper is in theory 3.4% taller)
take 3.4% off of your 11.6 and 10.8 => 11.2 and 10.4.
now lets look at the revs at 100km/h
Assume 3.909 diffs and .799:1 top gear.
