Who hypermiles their sports car?

[Three6Eight]

I just got a C5 Corvette and I have a 530 mile road trip coming up in 2 weeks.

I've done this same road trip with my 6.5 Diesel pickup. I got 21+ MPG going 60 the wholeway so it was really slow. Easily made the trip without refueling because it had a 33 gallon tank.

I've done this trip with my Supercharged Regal and did anywhere from 55-65MPH no WOT runs and got 31+MPG. Couldnt make it without refueling because it has a 17 gallon tank and I chickened out at 450 miles and refueled because the gas light came on.

Im going to do my best to restrain myself in the C5.Its a manual so in 6th gear its doing 1500 RPM at 65 MPH. Im going for 30 MPG so maybe I can make it without refueling. 19 Gal tank.

Anyone hypermile a sports car? What kind of results have you gotten? So its ok to coast downhill in Nuetral on a manual correct?

1,500 rpm at 65? Wow! My car does 3,000 @ 60! It's OK for the car to coast in neutral, but it's illegal in some states. I wouldn't lose any sleep over it.

Yeah when I got the car I was shocked how low its turning in 6th gear at 65.

At 80 MPH its at 2000 RPM in 6th gear.

I really want to go for 30+ though so I'll restrain myself and stay at 65. I use this site as a game. Im a stat freak and my Vette is currently under the EPA rating right now so I have to bring that # up

The Durango turns 1750 at 60

Corvettes actually get pretty decent highway mileage. If you scope out the vette forums you'll see that people regularly get in the low 30s while cruising past 80.

It's the combination of low frontal area and a nice low overdrive.

My truck does 1600-1700 RPM @ 65 MPH.

Hey I had a 1999 Durango and for the life of me it couldnt break 12 MPG no matter how I drove it.

I saw you had a nice 16 mpg run averaging 80 mph.

You ever going to restrain yourself and try a long trip at 65 or slower? I think you can hit 20

I had to drive my 6.5 diesel at 55 MPH to stay under 2000
RPM in order to see 21.7 mpg. It was painful but the stat freak in me wanted to bump my stats up

Is it a manual? 5.7 Vortec? My Chevrolet Pick up is a 6.5 Diesel with a 4 speed auto and the only way I can stay under 2000 RPM is to stay at around 55MPH

This year I'll probably be swinging by San Antonio on my way home to visit family this year so I can pick up a dog around Christmas time. Maybe then as it would normally take me nearly 3 tanks of gas to do that trip and being able to do it with 2 would be nice. I have been very curious about what easy driving and a normal highway pace would get me.

Unfortunately, I-10 serves me with a good 200-300 miles out of 1,100(one way) with 80mph speed limit area so that tank won't get treated well both ways.

Its a 98 GMC K1500 with a 4L60E 4 speed overdrive automatic. The engine is a classic 5.7 Liter "350"

I noticed you dont have anymods yet. To tide yourself over why not gut the air box? Take a Jigsaw to it or a better tool if you have one and just cut open the biggest opening possible. Im sure your airbox has 1 small hole sucking air out of the fender. Might pick up an extra mile there. Everybit counts
