An extra 50 miles per tank is almost 3 more MPG, very unlikely.

Ditto on the 91 octane - enjoyed about 10% more mileage out of a gallon/tank on average

Some cars require it while others are just recommended. The VVT-i engine GX's (05 and newer) all require premium while it was only recommended (hence 87 may be used) for the 03-04.

That's not true according to my 2005 Lexus GX470 Owner's Manual under Fuel Selection section, 91 Octane gas is NOT REQUIRED, but "Recommended for improve performance" " Fuel selection: Select Octane Rating 87 or higher. For improved vehicle performance, the use of premium unleaded gasoline with an Octane Rating of 91 or higher is recommended." I've been using 87, 89, and 91 Octane gas and have not noticed any difference in MPG. |
