Per Gallon Mileage - 21.5 mi / gallon
 

My 1998 SLK 230 is running 21.5 miles per gallon. I only run on local streets, not on freeways. Is this within the normal range? If not, what can I do to my car to get better mileage?

i think it is normal. I have the C230 K. I cannot go under 12lt /100 km in city driving. Convert this to mpg and compare it. Anyways, I think it is normal

Today in a round trip from Bangkok to Ayuthaya and back to Bangkok (about 200 kilometers...95 percent on a fast freeway) I got 7.9 L per 100 Kilometers....that's about 29MPG.

In city driving...in Bangkok...I get about 10Lt per 100Km....or about 23MPG.

Though traffic in BKK is excruciatingly slow (in rush hour I can walk faster)...the highway can be dangerously fast. Today I was doing about 130kph on the freeway...but lots of cars passed me doing 160+. There is a nominal speed limit of 80kph (for fuel conservation) but no one pays any attention to it. They don't even slow down when the men in brown are around.

My 1998 slk230 gives about 24 on easy driving in the city. Less if I push it a bit.
On the highway cruising at about 100kph (62mph) I get between 32 and 34 mpg.

23-29mpg USA. All around driving with no lugging. 01 SLK 320 Auto. I have a K & N filter and for some reason get better mileage using premium.

Yesterday while driving in Bangkok I got 16.1 L per 100 Km or 14.6 MPG. And that is with a SLK 200 and a 4 cylinder engine. That just shows how bad the traffic is.

I just completed a run today at mainly 100kph (62mph) for 200 kilometers (125 miles)
with a couple of town stops and lights in between.
I got 37 imp mpg or 7.5 l/100ks
