2) The dealer strongly suggested using 91 octane fuel yet the manual says 87 octane could be used if there are not any performance issues, such as engine knocking. Anyone running 87 octane out there?
1) 3rd row cancels spare tire. Left with rft and possibly buying a can of fix a flat.
2) use 91 unless you cannot find 87. 91 is a must. If by any chance you have fuel issues in the future, BMW may use that against u. Do yourself a favor and purchase 91 enjoy the engine performance as it was designed and possible future hassle.
BMW and Mercedes Build Beta Products!
Lexus build Release Candidate Products!
Why does this matter?
CAUSE EVERY TIME someone says Lexus has better build quality, one should consider what Toyota their Lexus Engine and chassis platform comes out of and how long that part has been tested in the real world!
