Yeah, manual's going to get a higher mpg. We're all struggling with auto's.

 

I have a 92 Club Cab I think the rear gears are 3.55 I put a 3 inch single exhaust with a huge Magnaflow muffler, K&N filter, removed the air dam in front of the snorkel, Accel Supercoil ignition system with plugs, and a Jet Performance Stage 1 module...I used to get 21 MPG (Canadian gallons are a little bigger) and the last highway trip turned out to be 26 MPG with more power and a cleaner sound

 

This with averaging 70 MPH

 

Not sure if mine is great. Engine runs nice but fuel is expensive. (Pricing info in liters Canadian)



I throw 10 bucks in it every day on average to go to work and back which is about 20km there and back.
