Gas Mileage

It is safe to say the 6.0 Litre V12 is not the most fuel efficient of engines. With 13/20 mpg (cty/hwy), the fuel costs are much greater than that of non V12 Mercedes'. Even with the filter upgrade, the mileage is (conservatively estimated) at 15/21 mpg. Recently, I have heard of several different products (one being a magnatized attachment to the fuel line) which "supposedly" improve gas mileage. Does anyone know of an actual product (besides the filters) which could improve the gas mileage?

SL Brabus,

Nice car. Did you opt for the 6.0 Litre or 6.5 Litre conversion?

Regards

Mr. Brabus, making me find out the hard way . Anyway, I'd love to check out one of those MB Auto Meets. Any in the NY/NJ area?

Regards

One day, if luck is with me, I'd go for the 7.3 Litre V12S conversion.

TheV12Pwr and StephenK,

Of course the performance is a top priority. But when has a little practicality ever hurt?

Regards
