Didn't read all the response but the new Circle K across from Home Depot.

So you're saying, if I'm reading this right, that my 2000 Land Cruiser V8 engine, that the manual says should be drinking 91/93 octane pure gas, but has been getting 89/90 pure gas or E10 for 179K miles, could have been run on 87 E10 all those years, except when I was going to pull a trailer or head to the mountains?

If so, there's a pile of $$$'s wasted... although I'm assuming that the mpg would drop, just like I see a 10-15% drop in mpg with E10 vs Pure gas (89/90 octane).

Yes, If you keep your foot out of the pedal with 87 you will be fine. An engine designed for 91/93 octane will have knock sensors which will compensate by retarding timing. You most likely will notice a difference in power or mpg. The thing is, at idle and light loads you never get close to pushing the limits of octane. Climbing a long grade, accelerating hard, and towing are where octane (ignition knock) matters.

Or if you have a manual transmission where you can lug at 1500rpms and mash down on the pedal in high gear.
