It should not be, but was it a 1 off as in you cleared the code it did not come back ? Could be iffy gas too.
I’ve been frugal and I’ve been cheap when it comes to octane rated gasoline I’ve used in all my LR’s. If you’re towing, loaded down then you will certainly be better off with higher octane fuel. However just driving around or off road you can get by with a lower rated octane fuel.
Biggest thing I see with fuel is the amount of ethanol added. It’s not very kind to the fuel pump wiring, or the rubber used throughout our fuel systems as it wasn’t designed for it. I’ve changed a few fuel pumps out that basically had zero insulation left on the wires due to ethanol in the fuel. It’s kinda like the government’s way of saying fine you don’t wanna drive a Prius, then we’ll add ethanol to the fuel & rot your vehicle out from the inside...

Lower octane meaning.. what?
In CO, we have 85, 87 and 91..

You are correct in that the octane related needs your ECU has been programmed to accept are altitude related... Generally speaking North American destined vehicles with V8 petrol engines are programmed to operate on 92 octane non ethanol fuel. The ECU computer is not reprogrammable or tunable. The knock sensors will retard the timing to meet the demands of the fuel you choose to purchase. That just means that D2's are programmed to meet the needs of the year of design with the fuel available at that time. Pre 2004 is mostly pre ethanol. Thus given than we cant retune the ECU we have to adjust our fuel buying habits or accept the retarded timing associated with sub par fuel per the ECU programming. You can buy cheap fuel but that comes at a price in less mpg and retarded timing. This was actually a design "feature" that your vehicle could adjust to any irregular remote fuel supply to get you to the final destination... which comes at a cost.... usually both lower mpg and less detergents in the system. Keep in mind, even though D2's may be cheap now, they were sold as and still are premium class vehicles. You still have to maintain them as such....

Definitely jealous of you Canadians who get ethanol-free Shell 91.
I personally put Shell V-Power 91 in mine exclusively. I wish I could try out ethanol-free gas, but around SoCal that's hard to come by.

Yeah I find the ethanol free fuel at Walmarts & Krogers around here, but even then it’s rare & it’s normally just 87 octane. There is one fuel station that has 100+ octane racing fuel, but $$$$.
