Hi there,
I'm new to the forum but it looks like a great place...think I'll be spending lots of time here!
Anyway, I've ran a search but couldn't find a conclusive answer. I've just had the oil changed in my car for the 2nd time since I bought it and the mechanic put the same Semi-Synthetic 15W-40 Diesel oil (MB 229.1 approved) in as before. The car has done 47000 miles so I'd expect the engine to be in pretty good condition inside.
However, I've been finding the fuel consumption (+/- 30MPG overall average) on this car a little higher than other E300's I've driven before. I'd be very interested to know other drivers fuel consumption figures as I can never get it to do more than 33MPG even on a long steady motorway run! I checked up on the oil spec and some people say 10W-40, others 15W-40 and various other specs. Basically, my question is could the thicker oil be affecting the fuel consumption?
Thanks in advance for any advice.
Best Regards,
Michael
