gas milage?

hey ya i was just wondering what is the average gas milage for a 92 gmc sonoma 4.3 v6 is? i always reset my trip when i fill up and when i get empty it uaully ends up being 250 miles to a full tank of gas. so ya but im also 17 and i drive pretty fast i guess. and my truck has many many miles on it over all though. a total of 198000. but ya how many miles per gallon should i be getting in the city because thats were i always am
thanx!

my 2001 crewcab 4x4 gets about 16-18 MPG with the V6, it sucks! my 05 GT with a V8 mustang gets 20-21

i've got the 1996 4.3 FI with a 5 speed manual and i'm averaging 20-22 mpg city and highway. but it's also 4x2. also, i was looking at 92 GMC sonoma, and does anyone have any info on the GMC syclone p/u ?... 280 hp out of a supercharge/turbocharged 4.3? not bad in 92.

i have a 1991 with the 4.3, automatic, and 197,000 miles on it. it a two wheel drive and it needs a tune-up bad. 90% of my driving is at 70-75 mph and i average about 20 mpg. in town i dont know, but if you are getting 17 that sounds pretty reasonable
