Tips on Buying Cars: Lexus Rx350, premium fuel, luck steve

Question
Hey Steve,

We're planning on buying the 09' lexus rx350.  I know premium fuel is recommended but it can use regular too but the fuel efficiency will go down.

I was wondering if anyone knows the MPG on regular fuel and MPG on premium?

If the premium is more efficient, then it will only cost a negligible amount more, but if not then it wouldn't be worth it.

Thanks:)

Answer
hi,
if you you regular or mid-grade, fuel economy will drop 3-4 miles per gallon. If you are willing to spend the $40,000 for the vehicle, i recommend sticking with the premium fuel, over the year it will cost maybe $500.00 more unless you put over 20K miles on the vehicle. Good Luck!!!
