Hi All,

I am looking at updating my crusier Currently 4.5ltr petrol but I am interested in the difference in fuel economy between diesel and petrol 100series. Petrol will obviously thirstier but the difference in price between the 2 engines at the dealer is a alot of petrol at the pump + the service cost of diesel vs petrol

Can anyone shed some light

Some more food for thought besides the servicing is the fuel price. When travelling recently we discovered in country areas diesel was, in some cases, the same price as ULP and in one case 10 cents/litre cheaper!

Most a prospective buyers are put off by the city diesel prices..

Father in law has a fully equiped 100 series td with a host of ARB gear, roof rack, locker lights bullbar suspension etc etc. HE gets with all that weight around town 13L per 100 i think in the auto. My boss here at work just sold his V8 cruiser and was getting 252l per 100 around town. As far as cost is concerned, you pay more for the turbo diesel than the petrol however the diesel will hold its value better and therefore you have a better resalve value. The petrol will drop in value considerably once you have 100,000kms on her. In other words buy high sell high with a diesel. Furthermore its not just about fuel consumption or the price of the vehicle its about rev range, gear ratios, kw's and torque. Go the turbo, plus their not hard to service yourself either. Hope this healps, make sure you make a decision on whats best for you though and not anyone else's such as a diesel nut like myself.

Andrew, I'd need a second job at that fuel consumption. Thats horrendous!!! But i think it should read 25.2 but thats still crazy. I'm using about 11.5 litres per 100 ks. also love easy driving around bush tracks, drive all day and the needle doesnt move much but the petrol guys are complaining about the usage and wonder which way to find fuel in the next morn.. love the diesel.

Michael - I can't believe that they use 25.2 - I know the extra servicing costs of the petrol negate the advantage of the diesel to some extent, but I would hate to be using twice the fuel I currently use.

Larry - I have a 2002 1hz with after market turbo (safari) equipped with bullbar, winch, roofrack, 285/75/16 at's rear drawers extra battery, heaps of other heavy stuff.. 13.5l per 100 round town - usually 14 - 14.5 highway - I put this down to extra weight on h'way, coz Im usually goin away, and also the roofbag on the rack would create a bit of drag. I never sit on anything quicker than 105 kph...

The biggest advantage of a diesel is your fuel range my auto T\D averages between 7\8 klms per lt my petrol used to average between 4\5 kpl with 140 lts in the tank I can travel nearly 400 ks futher for every diesel fill. Huge advantage for me. Cheers Rob

According to NRMA, unless you're going to keep the vehicle for something like 300000k's, the V8 IS cheaper to own when ALL costs are taken into account. There's alot more than k's per litre to consider. The fact that the diesel has better range and fuel availablity for outback travel though, isn't taken into account in their argument. If your going to do lots of remote area travel then buy the diesel, if not, petrol. Just my opinion+some facts from NRMA.

To add to the mix......Toyota are real interested to shift some v8 100's at the moment....they will lower the price thousands, and accessorise them....even heard of one dealwership gassing them to get em out the door....
The v8 would love gas..... if you consider that viable, only look at running injected gas ....as it is soooooo much better than the systems of yesteryear....look up vic gas or Parnell for a quote. Friend just had his 120 prado done, and he is happy as...

Hi Larry,

I've had two TD GXL 100 series and now a new V8 (done 42k).

The average TD fuel consumption over 40k was 13.9 l/100km
The average V8 fuel consumption over 40k is 15.4l/100km (I drive it pretty hard – even after 40k I still like to floor it and get a buzz)

WOW it costs me an extra 1.55L per 100km to run the V8!!!

I took a TD for a test drive a few weeks ago – feels like a tractor to drive when compared to the V8.

One day I was mucking around going through tight corners with the shifter, then pulled out on the highway, after a few minutes of cruising at 100km/h I looked down and saw the tacho sitting at redline (or near to it) – I was still in second gear and didn’t know it – the engine and auto combo are silky smooth and quiet.

I thought the V8 would be a lot thirstier than it is. Pulling a 3.5T boat cost me 25.6L/100km over 1100km which is pretty good as I drove it very hard (roof rack + 3.5T boat at 110 km/h)

Cost - Petrol $1.20 cpl, Diesel $1.25 cpl

1000 km trip – V8 $185, TD $173
25,000km trip – V8 $4620, TD $4327
200,000 km trip – V8 $36,960, TD $34,613

That is $2300 extra for the V8 over 200,000 km – what is the TD purchase price premium again?

The TD is A LOT more expensive to service if you follow the Toyota service manual - given the small margin between the economy of the engines there is a big margin in the servicing costs – I got a shock then I looked through the manual, then I realised that 80% of the information was for the TD models. The V8 is oil and filter every 10,000.

Check out the NRMA web site, motoring page, then operating costs page – the V8 is cheaper to own than the Toyota GXL 4.2 Diesel, 4.2TD AND the Nissan 4.2TD.

I run a lot of vehicles at my business (on a mine site – so not treated with much respect):

Average economy figures (L per100km):

GXL V8 – 15.4 (best hwy - 11.27, sand tracking – 20, average range – 924km)
100 Series TD – 13.9
100 Series D - 14.93
Hilux 3L TD (2005) – 12.52
Prado TD – 13
Nissan 2.4L TD – 13.93 (needed low range to get over a speed hump)
Pajero 3L petrol – 17.45
VL Calais (non turbo) - 12.83

Mate, I own both a 6.5 diesel Landcruiser and a 4.5 petrol / LPG Landcruiser. I understand the differences and benefits of both fuels. Let me tell ya that the petrol is a sensationally good rig. It goes real well, has plenty of torque and has a tougher drivetrain than the NA diesel.

I did a back to back comaprison before I bought it. Drove a new 1HZZZZZZZZJ105 approx 2,000km's, hopped out and straight into a FZJ105 for a similar trip. There's about a 3-4l/100km difference in fuel consumption and about a 100% benefit in driveability. Around town for day to day there is absolutely no comparison. The argument that petrol's have no torque is rubbish. The 4.5 makes plenty right from idle.

I have an Impco LPG system fitted to mine which runs as smoothly as petrol. It gives me 210 litres of useable fuel (95l petrol, 115 LPG) so range is not bad either. At 50c per litre it puts a smile on your face when you fill up (in comparison I filled my diesel a couple of days ago @ $1.29/l - strewth!) The 1FZ-FE petrol engine is super reliable and cheap and easy to service too.

I'd love a factory turbo diesel but won't buy an IFS 100. Do the sums and more importantly, DRIVE THEM BOTH before being being swayed by folks using 'pub expert' arguments from 20 years ago. Remember, we are not talking about carbied 60 series here. Listen to people who actually own and drive the vehicles you're interested in.

It's horses for courses. Be honest with yourself and work out what you will really be doing with it.

However....on the other hand, when I come into some spare cash, I'll be slotting a Chev 6.5 diesel into my petrol 100. Until then, I'll keep going where the diesels go, but quicker and cheaper.
