C43 AMG
MPG in SLK
Hey everyone, I am going to Ocean Shores, WA on Sunday, June 22, 2003. It's about an hour and a half drive from Seattle and Portland. It's an all Euro car meet, and should be fun (hint hint, come!). Anyway, I was wondering what kind of gas mileage you normally get? In town I tend to get about 20, where on the freeway I can expect 24-25. Not bad for a 3600 lb V8 sedan! However, I do in fact have a C43. What do you all normally get? If you aren't sure, try going to OS this June in your AMG if you live in the Pacific Northwest and you will be able to find out!!!!!!!!!!!
Magazines and what not claim 18-22, but I get better... Do you get better than what is claimed for the SLK-Class?

Mileage is better in summer than winter. Warmer weather gives me 25mpg around town and 30 on the highway. I lose about 5mpg from both in the cold weather. I'm not an agressive driver, but I do like to play a bit with the SLK's power and cornering ability.

SLK 320
I also notice that the brand of fuel I use makes a somewhat significant difference on MPG. I get about 20.6 average(hwy/city) using 76 fuel, and about 18 average(hwy/city) using chevron fuel on my SLK 320.

When does your low fuel light turn on?
After filling up a full tank and mix freeway and local driving, the light turns on after 210-220 miles...

'99SLK Sport, silver
I get 24 averqage. 26 on hte highway with the SLK.
Interesting, I got 24 with my '99 C 230K and 26 on the highway. Then I changed the muffler and the average went to 26 and the highway went to almost 30. And that was fully loaded going to Whistler, BC.

I write the mileage on every gas station receipt and compile them in a spreadsheet every few months.
For my previous '99 SLK230 M/T over 12,000 miles
Average City: 20mpg
Average Highway: 29mpg
Best ever: 31.9mpg
Worst ever: 18.1mpg
EPA estimate for this car was 21city/30highway
For my current '02 SLK32 AMG over 10,500 miles
Average City: 16mpg
Average Highway: 26mpg
Best ever: 28.3mpg
Worst ever: 14.0mpg
EPA estimate for this car was 18city/24highway
The good thing about the SLK230 was that, unlike the SLK32, the fuel economy didn't suffer much even when driven agressively. However, both cars got significantly better fuel economy at 10,000 miles than they did when they were new, so I can see how magazines testing a new car would report worse fuel economy.
FYI, the 1998-2000 C43s were rated at 18city/23 highway and the curb weight is 3448 lbs.

'02 SLK32 AMG with 10,000 miles
Average: 16.06
Best: 24.89
Bad: 13.75
Worst: 7.03
All numbers are for a full tank. Where we live the car does a lot of short trips (1-2 miles) so the mileage is even worse than city it seems. Bad is really the worst on the street mileage. The worst mileage was recorded on track days. I get between 7 and 9 on the track.
I have also noticed the mileage work it’s way up approximately 1-2 MPG after break in.
