450SL - Cunsumtion of gasolin

Hi Everyone... I wonder if you guys have an oppinion of how much gas a 450SL - 1974 (usa-model) should "consume" lets say...3000rpm....100km/h

On my 78 450sl over 1000 miles combined city highway gives 15.666 MPG. My 300DT gives me 26.435 over 1000 miles. I find due to amount of variance on tank fill ups you can not get anything accurate on MPG so I take fuel usage over 100 miles.

These are thirsty cars because their engines were detuned to meet emissions regulations - compression lowered etc. As I recall US EPA mileage estimate was about 12 mpg / city and 16 mpg highway. "mpg" is miles per (US) gallon.

I can routinely get around 15 mpg combined city/highway travel (about 50% each), but that's with the spark advanced as far as the manual permits.
I'm very curious how involved it would be to substitute European version 107 series cams into a USA model 450 SL to see how that would affect mileage & performance. My understanding is that the Euro version 107's are notoriously better performers than the USA models - particularly compared to the California version like I drive.

A 450SL does sound like a thirsty car anyway, to me. However, considering that my second (and fortunately last) Daewoo Lanos was only giving me 22 to the gallon, it really doesn't sound too bad.
It's a shame that de-tuning is necessary with some cars to make them US-legal.
Still, the best thing I ever did was leasing my Merc... A160 CDI (Classic SE for those interested), 2003, giving me 43 mpg (Imperial). If it carries on this way, it will have saved me a fortune by its "retirement" in December 2006.
(I am forced to retire my car after 3 years but am free to lease another one straight away.)

Wouldn't it make more sense to just use L/100KM? Drive on the RIGHT side of the road? Or are Brits just averse to Napoleon's improvements? :-)

Driving on the right is not an improvement, just an arbitrary decision to sort out the variations all over Europe under the Napoleonic jackboot.
We have been driving on the left, the natural side, for at least two millennia.
So there!

It's to compensate for all the pollution caused by the idiotic giant sized American engines.

I get 12.5 MPG consistently with my '73 SLC. This is with a mix of highway and in-town driving.

In 1970, I could buy gas for 30 cents a gallon and get a free car wash or Loony Toons glass with every fill up.
