Fuel Grade for the LR2

[riminirover]

Need some guidance on the fuel grade touse on a new 2008 LR2 HSE. The manual says to use Premium Grade Fuel (91 Octane) but does say you can use 87. My question is has anyone been using 87 or 89 for a period of time and not had any issues? I would like to use regular gas but only as long as I will not be regretting it later on in terms of fuel efficiency and/or engine knocking. Please Help!

I've been running mine on 87 Since I bought it in May 2007 with zero problems. I've only put one tank of 91 in and got bad gas mileage.

87 octane since day one, currently averaging 21.2MPG mixed city/highway. That's sweet compared to the 16MPG I get in my XTerra.

umm, from a rover owner with decient knowlage, you should be putting ATLEST 91 (i put 93 in mine). The cylnders run hotter in rovers and need the extra boost for some reason i cant explain. you can run 87, but you shouldent run it long (ie a full tank every few mounths). You mostlikley wont feel the effects of it now, but in about 20k miles you will start having problems (leaking head gaskets), then after 50-70k you can see large problems costing in the $1000's.
YOU HAVE TO PUT ATLEST 91 OCTANE, CHANGE YOUR OIL EVERY 3,000 MILES!!!! i know land rover recomends 7.5k but thats the minnimum, you CAN NOT do the minimun with these trucks if you want them to last over 50k. WHEN LAND ROVER SAYS SOMTHING, THEY MEAN IT, AND DO BETTER THEN WHAT THEY SAY, that just how it goes.

when people start "cutting corners" like this, you get the "LAND ROVER SUCKS, NO RELIABITLY" going. there IS reliability in these trucks, you just have to do better them the recomndations change oil2 times every time they say 1, and USE 91 OCTANE NO MATTER WHAT!

the reason you had worse milage with the 91 jenin is due to the switch, if you had kept it for a few tanks it would have gone back to normal, but your engine was adapting to the new fuel and in doing this youll get poor milage
