| Last week I was involved in an accident and totalled my 400E. But when I was driving my 400E I always used premium and never thought twice about the extra $4.00 everytime I filled up. What the heck, forget your latte for the day if it bothers you that much. On one occasion I was in the boonies of Alabama and stopped to filled up finding out that I had a choice between diesel and regular. I filled with regular and the car ran like garbage; missing, lack of power and guzzled the fuel. When down to 1/2 tank of fuel (not very long) I filled up with premium and noticed a difference within miles. As I recall it took another tank to get my mileage and performance back to where it should be. So for me, if you own a Mercedes you need to treat it like the quality vehicle that it indeed is. Don't scrimp on fuel. |
