[DMCForum] Re: DeLorean MPG

["content22207" <brobertson@xxxxxxxxxxxx>]

Whenever DeLorean owners start making MPG claims I always get out my
Bullshit meter (there's only one other measurement they lie about more...)

Official EPA rating was 19 MPG (upper teens in town/low 20's on the
highway). Car & Driver real world test dropped that to 18 MPG. If I
hold my engine speed around 2,000 RPM, I do indeed come close to those
numbers.

But it's physically impossible to drive 65-70 MPH in a PRV/UN-1
equipped DeLorean without spinning the engine closer to 3,000 RPM.
That increases fuel consumption 25-30%! And the 5,000 RPM I pull from
a stop light absolutely massacres fuel economy. 

But I didn't buy a DeLorean to be an econobox, or to drive "gently".
It's a sportscar, not a Yugo. If I can't afford the gas, perhaps I
should reconsider ownership.

If you're intentionally running your engine lean for MPG, be careful.
Lean mixtures are as bad for the combustion chambers as rich ones are.
You run a real risk of damaging the pistons or heads. Speaking as a
person who just burned a hole in the piston for his lawn mower, it is
indeed possible. I'd much rather buy an extra gallon or two of gas
than rebuild or replace an engine.
