| How to fill up C300 loaner with E85 flexfuel?
I got a C300 RW loaner and need to refuel before returning it. Can I fill her up with E85 flexfuel (MB approved) while there's still premium 93 gas in the tank, i.e. mixing them up?
Also, will I get more power with E85 since it has an octane rating of 105?
Thanks!
