1972 buick skylark mpg?

[jitz]

I would like to get an idea of the fuel economy and horsepower of the 1970-72 Buick Skylark, both the normal Skylark with the 350 (assume 2bbl carb) and the GS with the 440 which I believe only came with a 4bbl. Info on these cars is harder to come by then other muscle cars and questions to owners only yields the "why would you need to know the economy of a muscle car?" which of course isn't much help. I know its a muscle car but I plan on buying and driving one often and will put in the money to make it get better economy if I have to.

First, EVERYTHING you would want to know about these cars is available here, www.v8buick.com. Second, gas mileage is going to depend on lots of things. If you are talking about a bone stock car, again, it depends on how it was optioned. A small block (350) will get better gas mileage than the big block (455). BTW, a 440 is a Mopar engine. A heavier car with more options gets less gas mileage. The axle ratio has a big influence also. Higher numerical gears spin the engine at more RPM at any speed burning more gas. 1970 cars had more compression, which makes for more efficiency also. Compression ratios dropped in 71-72 cars

In general, the 70-72 Skylark came standard with the 350-2bbl and 2.56 gears out back. Back in the day, they were capable of up to 20 MPG. On today's gasoline, that number would be less because of the ethanol content. The GS455 came standard with the 455 engine and 3.42 gears. They were capable of up to 14-15 MPG, but on today's gasoline, about 12 MPG. Now if you modify things, all that goes out the window, and mileage generally suffers. Visit V8Buick and join.
