Do your self a favor and burn what you buy at the pump. If you ever have a problem and it falls back on one of these mixtures, Rover can and will void that part of your warranty with just cause.

 

9.35 to 1 may not be anything but it is when the timing
is set advanced like Land Rovers are.

Even at the cam LR's are set advanced sowhen the chain stretchs it will still be it timed for the ECM.

 

certainly an additional $3/ tank is worth the head ache. A bottle of boost cost more than that!

Also the majority of Rovers in "undeveloped" parts of the world are diesel engins that will run on darn-near anything.

Of course in Africa, New Zealand and many other countries, the octane of their gas if up in the 97 octane range.

 

That's not directly comparable since they only measure Motor Octane Number. Our octane rating is an AKI which is MON+RON/2. Their 94 MON compares closely to our 87 AKI.

 

Interesting discussion. I think the next vehicle I get will either be a Range Rover or a Land Cruiser. I wonder if the newer Rover engines that (I think) were BMW designed are better running and more reliable? I'm slightly disappointed in the Discovery's power train design the more I hear about it, but what the heck nothing is ever perfect. It's still a great looking vehicle and has nearly all the features I like having in an SUV. Spending $3 or $4 extra per tank is no big deal to me to keep a vehicle running smoothly and reliably. But I'd be interested in seeing a comparison between Rover's new 4.4L V8 vs the old Buick 4.6L vs Toyota's new 5.7L V8 in the new Land Cruiser.

 

It's a real shame we can't get the diesels here. I got to spend a lot of time in a pre-production07 Defender with the turbo diesel, and it was fanastic. It was a little pokey on the highway, but around town it was great, and the fuel mileage wasso much better.

 

Roger that on the Diesel thing....Blame it on California emissions laws and America's in-ability to get the diesel smoke belchers of the 70's out of our minds.

Jeep almost had it but they had to stuff the diesel motor into the P.O.S Liberty. I shake my head in shame....

The diesel Liberty was a fiasco. It almost didn't happen but for direct involvement from Zetsche.

 

OK so...with this being stated....what are the chances that the Brits calculate Octane differently thatwe doas well, and perhaps their 93 is actually equal to our 86.
