No difference to our old girl, at least with the V8 your not flogging the crap out of it to go up the same hill.
Thanks

That would be NOT towing I take it.

I own a 2007 LC100 V8

I just towed a small van around AUS and got around 400 from the main tank and 150-200 from the sub. And that was driving very economically so if anyone tells you different, they are fudging. But then again, after that I only put 120 litres in, so still had 20 litres left !!!

I have heard many stories of great fuel consumption...but it doesn't get too much better than above. I tried very hard to improve it with different speeds etc, but the only improvement I got was with a GOOD tail wind

And to me, that is fantastic and I now own a 2.4t van and still love the V8...it's a beast and I LOVE IT

Old girl generally the v8 is more ecomonical then the 6, sounds strange but it is true. boss had two 4.5 sixes then the v8 and it was better in most situations. Down to 13l/100 highway cruising unladen. He now has the v8 diesel and starting to wish he had the petrol v8 back as it is burning a lot of oil.It has now done 28000ks.
Cheers Pete

Pete, Toyota now has a fix for excessive oil use. Get him to take it back to his dealer. Reports are that oil use completely goes away when fixed.

Hi Old Girl

I can't comment on the 100 series directly but with the similar Patrols the manual certainly allows for much better economy accept in the case when you have reached cruising speed and are just sitting on it , and in this case the auto wins.

Overall the effect is to convert the autos slightly better econmy to an average 5% overall loss on a typical trip and this loss increases the more time you spend in the rough stuff.

Hi Old Girl,

We have a late '05 100 series V8 Auto. On the highway (and not towing anything) we get about 12.5-14lt/100km. We've just come back from a 1200km trip over New Year towing our camper/trailer (about 850kgs) and consumption averaged 16.8lt/100km. This included a bit of mild dirt and sand tracks without the trailer.

While I love the amount of spare power available, if you use it constantly, it will rapidly drain the tank! Depending on road conditions and other traffic, we tend to sit on 95~100kph. Much faster than that and consumption rises steeply.

Hope that helps.

Cheers,
Chris

Hi Old Girl, We have recently returned from a trip to West Aus and covered some 20,000 ks in our 2002 V8 cruiser with 2+t van in tow and we averaged 4.46ks per liter and this was done trying to keep our average speed at 80 to 85 kph.
Cheers
