| RE: Regular vs. Premium Fuel in SLKs That's interesting because one of the local news stations did a program on this subject and the outcome was premium fuel was not required for most cars EXCEPT high performance engines like Porsche, Mercedes, etc.
I am going to continue to use Premium. If you look at it logically, the difference is only about $3 -$4 per fill up. The cost of a Starbucks double mocha latte[:D] |
