Could anyone tell me how many miles to the gallon an '87 IROC-Z with the LG4 got from the factory?

 

about 25 on the hwy, 17 in town would be my guess

 

How about a '91 RS with the L03?

 

Thanks.

 

My L03 got 25-27mpg on the highway; I bought it in Ohio a few months ago and drove it home to Texas.

But now that I'm in the city and hammering it WAY too often, that's gone down quite a bit.

 

I wish I got that kind of gas mileage. I drive a 1959 Dodge custom royal 4 door everyday!!! 361 motor with push button trans. 57 thousand orig miles, great car, anyone wanna buy it? $3,500

 

My 91 rs got a consistant 25 mpg driveing from wheatfield indiana to columbia missouri. Seems to be getting about 18-20 intown (if i manage to keep my foot out of it).

 

Iowa to Florida......1,600 miles.....I averaged 29.7 MPG in my 1992 Camaro RS with a TBI 305 with no mods....

I get about 15-18 MPG in town..............

 

flyinlo: how did u get 29 mpg? I was thrilled to get 25mpg last week driving the Pa turnpike northeast extension ,up rt. 81 to Syracuse. On the way back,I got around 21 mpg. I think the difference was that I drove to Syracuse at night with cooler air.

 

17/26mpg

1987 LG4

16/25mpg

 

I'm thrilled with my mods to get 12mpg in the city.

 

Get going about 75 mph and just keep it here .....I guess i forgot to mention that i ran without the A/C the whole time....
