New Prado - engine issues ?

[Guest Close Guest]

thanks amts.
do the petrol models have the 150L tanks like the diesels ?

Tanks on both engines are the same size.

I was camping with a mate at Straddie before Easter. I was telling him that 95% of new Prados sold were diesel (Toyota's figures). Well I just about had to eat my hat because what we saw on Straddie was literally the opposite. Almost every Prado there was petrol and we saw dozens of them. Every owner I spoke to were from Brissy. What it said to me is, if you only plan on travelling short distances, the petrol may be more than adequate. If you can see yourself doing the Cape or other famed Aussie routes, get the diesel. If you plan on selling it in a few years, get the diesel. It will hold its value much better and be easier to sell.

As amts said but also Diesel is a lot safer if you have to carry extra fuel, which if you have a Petrol you are more likely to need to do. Drop a match in a bucket of Petrol and you have an inferno, drop a match in a bucket of Diesel and the match will go out!

Incorrect, liquid fuels don't burn as there is no oxygen which is the catalyst. Heard of the air fuel ratio? Only the vapour burns when mixed correctly with O2.

On both occasions a match or cigarette will be extinguished by the liquid. The only difference is petrol vapour ignites faster than diesel vapour. And petrol evaporates faster making the problem worse.

Saw dust in the air will explode like petrol is the air fuel ratio is right, plenty of silos have been blown to pieces because of this phenomenon.

Yes I've heard of fuel air ratio and I realize that only petrol vapor will burn. At any temperature within the normal range for Australian conditions petrol will vaporize when exposed to air, as in my example of a bucket and if you put a match to it, it will ignite, quickly and easily. Diesel on the other hand is actually quite difficult to light with a match.

Diesel has a much higher flash point than Petrol, making it safer.

Have you ever been out in the Desert refueling vehicles in 45 degree temperatures? I can assure the guy pouring petrol into his car is far more concerned about a possible ignition source than the guy pouring in diesel.

At fire training some years ago we had some open containers filled with water and a few litres of diesel or petrol on top. It was a 30C day. Every time a lighted match or cigarette was tossed into the diesel tank it snuffed out without any smoke or signs of fire. The petrol ignited every time BEFORE the ignition source hit the liquid. Regardless of whether the liquid will burn or not it is the vapour that starts the blaze. As for dust lots of things will burn, rusty steel swarf from a lathe will burn intensely and is hard to extinguish. I had a lecturer once say that one of the biggest explosions he ever witnessed was in a flour silo in the States. Took his mind off sex for over an hour he said.
