When it costs $100 to fill up is the $4 difference between regular and premium really that big of a deal. It's better for your car and you get better milage. Regular costs you more in the long run, as Mike said. I know this has been debated back and forth but... I really don't see LR taking the time to print Premium in the manual if it wasn't a good idea. No consumer likes a vehicle that requires Premium so if they even felt the difference between Premium and Regular was marginal they would have left it out.

Bottom line, it's your car and you can do what you want but I recommend A) buying a good quality fuel and B) using the octane the vehicle was designed for.

Oh and Mike, Right on about the fuels in SA, as well as many other regions.

 

Here in the good ol USA we do not have the best gas that is out there, we do have some of the cheapest prices though compared to other parts of the world. I have used both low pctane and high on my truck when I first got it. I did find that running an 87 lacked in the MPG that the 93 could give, and those that are mixed with 10% ethanol were a higher octane rating but were even worse. The idea here is a consistent one, if you are putting in $80 what is another $3? If you are so broke that you cannot afford the $3 then I am very sorry, you will end up dumping the Rover after you cannot afford to fix a damn thing on it so it does not matter anyways. Find one thing you can do in your week that costs $3 and do not do it, then you can now justify the $3 to use the recommended gas in your vehicle. We all waste way more money each day than whatwe are complaining about putting in our tanks. Also, in many third world countries they are using diesel anyways which is a lot better then ours avaiable here too.

Long story short, use the proper fuel, keep up on maintenance, and enjoy the truck like it was supposed to be enjoyed. Oh and on the poiltical note, it is not the price of oil in the gas it is also the taxes that the state puts on it that can really affect the overall price.
