Er, yeah. Divide trip by the gallons.

The fact is modern gasoline engines are just getting more efficient ,my son in law just bought a new Mercedes 3.2E bluetech an it gets 39mpg. and for V8 power my GTO gets 26mpg which is pretty decent for a factory performance car ,my thoughts are the future engines will just be more efficient performance which means power adders such as turbos an SC's will be common on many vehicles ,even Palsut could retain his 3.1 and with the addition of a Turbo setup he could retain good gas mileage an have performance also,we come a long way since the muslecars of the 60's were a 350 hp car was lucky to get 14mpg.Chico(pops)

turbo on 3100 engine? Only if it is true

Timeline for gas of my car.

Saturday night: fill her up to full.
Sunday: I don't remember I drive this car or winter beater either. (still full)
Monday: about 50 miles for work/home (still full)
Tuesday: about 50 miles for work/home (still full)
Wednesday: about 50 miles for work/home (start moving down but not reach to 3/4)
Thursday: about 50 miles for work/home (still haven't touch 3/4 but very close)
Friday: about 50 miles for work/home (finally pass 3/4)

You went 150+ miles on one quarter of a tank? I get 100 if I don't hot rod it...

Yes, is that wrong? If your is 100 but mine is 150. It could be extra 50 miles save gas?

gas mileage with 3800vs3100, 31 will win in the gas mileage race lol

Yes, but see, that's why if I agreed to a race like that, I would bring a shotgun with me. Tip the scales in my favor a little... ;-)

hahaha

For one thing you can't compare mileage by what the gas guage reads. They' aren't accurate enough.

In 2000 GM gave the 3.1 a rating of 20/30 and the L67 a rating of 18/28.

Which when you look at the difference in power 175 compared to 240 the differences are negligable.

Awesome pic Herc!

Need advice. My 2001 GTP has all the power I'd ever want in a midsize car. Problem is, it sounds like a lawn mower. Exhaust is totaly stock. Want it to sound like it moves. Any suggestions??

get a 3" dp. this will delete your ubend and free up some power while also giving your exhaust more 'volume'. remove the resonator just after this and replace it with straight pipe. then get some aftermarket mufflers of your choice or leave the stockers on and see how you like it. this will make it louder and give a nice rumble.

Swap in a V8!

lol that's good idea. I would like to race for fuel mileage but everyone are pussy to know 3800 ate lot of gas than mine. Who will be brave to vs. me?

I don't believe gm rating crap. I rather check my mileage and gallon to see actaully mpg for my driving habit.

lol way to kill thread. 3800 sound like lawn mower? ow... good to know

This morning, I took my car to visit my dad to hear the exhaust sound. He told me it is very good. He was driving my car lot. My dad is 70 years old. He feel like he is very young again. He rev it lot but I hate that but what can I do with that. He is my dad so I let him have fun. When 2 old couple walking outside neighbor. They saw my dad and he hit gas hard for "show off". I laughed. I bet this old couple thinking wow... old guy have nice gp and we have crappy lincoln town car. Now, my gas is almost reach to 1/2 but I have full gas can on my trunk if gauge fail.
