what fuel?

[jake_ak_cent]

what fuel does a land rover discovery use? ive had a couple people tell me i can only put premium in it, but coming from the people that told me who have no knowledge of land rovers, i wasnt sure if i should believe them.

LR recommends using only premium grade fuel in their vehicles.

There is a sticker right inside your fuel door, "premium only".
If you have your owners manual, you might want to read it thru so you become more familiar with your truck.

Most all car manufacturers say to use premium.

Don't forget you own a Land Rover!! The fuel system is very robust. I have driven Africa with a group of guys that own Disco's and have had no problem with their fuel systems..unless you get bunk fuel with water in it!!LOL. MOst of those Disco's have several hundred thousand miles on them and Premium fuel has been the absolute rarity in the trucks life.
If we all owned expensive Italian supercars then premium fuel is manditory..but we don,t...we drive Land Rovers that are designed to travel the Globe and go to very remote parts of the globe where Premium doesnt exist.

While not a Discovery, I have always used regular in my RR Classic. No problems, no pinging. Octane is less important the higher your elevation as well. Put a lower grade in. If it pings, then you need more octane, if it doesn't ping, then you are fine. No sense buying something you don't need.

[jake_ak_cent]

all you guys have made some good points for each side. i might just try regular as i live in the state with the 3rd highest gas prices in the country but i will definitely switch to premium immediately if i here pinging

If it's pinging, retard the ignition a bit untill it pings no longer. Keep an eye on the temperature gauge. If it gets hotter than normal use premium again.
The other thing is that whilst using regular might be alright, it could use more fuel to get the same performance so you could be spending the same as you would using premium.
I've noticed this with using cheap diesel rather than premium diesel we have here in Europe. With the premium diesel I get further on a tank full.

If you're really smart and have the supply in the neighbourhood, convert it to use propane.

[jake_ak_cent]

wow maybe ill just use premium . but propane conversion? how would that work?

[Rovin4life]

one thing you guys dont realize is that one countrys premium is another's regular.

octane ratings are the same but what one country calls premiums varies. So when a country puts in 91 as regular as australia does then you dont need premium as compared to america where regular is 87.

[XtremeMarine]

In the summer heat of Florida, my DII will get pinging with midgrade 89, so I use premium always. I figure for the extra money, (be honest people) between mid and premium, at 20 gallons a fill up; I am only spending an extra 2 to 2.50 a tank load. Even at one tank a week; you'd only be saving less than 10.00 dollars a month. So come on! Versus possible engine damage; I'll pay the extra 10 bucks. 100-150 dollars a year towards preventative maintenance...

[Dutchgit]

Fair point, well made by Rovin4life, I didn't realise that octane ratings are different in various places. 91 is the common minmum you can safely run a Rover V8 on.

About propane, or LPG as it's known in Europe, I've been using it in various cars and trucks over 20 years and it has never given me a reason to dump it.
Todays Propane systems are very well made and you can get a basic system as well as one with all the bells and whistles that will inject liguid propane rahter than the gaseous form that more commonly used.

Here's a small thing on LPG : HowStuffWorks "How Liquefied Petroleum Gas Works"

[jake_ak_cent]

that dual fuel lpg conversion sounds really cool, but how much would that cost?

[Dutchgit]

That would depend on what system you want and how much of the work you can do yourself. I've installed two systems myself and didn't find it very difficult.
I don't know about the availabillity of systems in the Northen Americas. Forklifts often run on Propane so there must be someone out there doing conversions.

[jake_ak_cent]

well how much do the conversions cost in germany?

[Dutchgit]

You are probably looking at about $3000 having all the work done with a later 'All the bells and whistles' system.
You can buy second hand systems from about possibly $500.
