How many miles per gallon does a 1988 Chevy S-10 Blazer 4.3L get?

Question

My Blazer get 10 miles per gallon I know something has to be wrong if anybody has any ideas give me a hollar

Answer 1

We had that very same Blazer. Even with 4 wheel drive , we still got about 15 miles per gallon. If you haven't been already, I would have it put on a scope to see if they can diagnose your problem.

Answer 2

I've had 3 of them... and you should get 15 city 22 hwy...with a/c and 4X4...

Scan it for codes, replace the IAC and do a tune up...make sure you have  a fresh PCV valve, they will cause you to leak oil from the rear main when they are clogged...if you ever had an oil leak from a rear main...check the PCV valve first...
