Last question, I thank all who responed to my transmission question .
I understand the Murano requires premium fuel. Is this true can this vehicle not run on regular?? With the price of fuel these days and its still going up whats a guy to do??

I know some vehicles say you must run premium but they run fine on regular I wonder if this is the same for the Mo.

you can run regular but u will get a rotten egg smell from the exhaust

I run Mid-grade 89 octane in my 04 Murano SL AWD and it seems to be running fine. No difference that I have noticed between this and the 93.

I've run regular, Premium and mid-grade. For the mileage difference I choose midgrade over regular. I have found no difference from premium to mid-grade.

I run regular with no ethanol and it runs great!!!
