Engine Performance problem
1997 Mercedes Benz SL500 V8 Two Wheel Drive Automatic 141000 miles
We have two older MB, 97 SL500 and 99 ML430. Both require Premium Gas. Q: Will it hurt either to use regualr gas or even alternate regular and premium. Premium Gas prices are killing us old farts! Thank you, David and Rosemary
have the same problem?
