Thread: Increase the gas mileage...what works for you and your ride?

I'm talking about aftermarket parts. I traded in my crew cab truck for a suburban w/ awd and the 6.0 engine. I have ordered a K&N cold air kit and plan (pending funds) on two other add-ons: Hypertech programmer & Gibson SS exhaust. Any ideas? That 6.0 loves fuel...I need to put it on a diet without hurting power.

I suspect the best aftermarket accessory you could buy would be an intake-manifold vacuum gauge.

It will do nothing about the engine's thirst for fuel. But it will tell you when you're lead-footing the gas pedal, and that will encourage you to smooth out your driving. That's probably the best thing you can do.

Makes since. Over the past year or so I have been trying to pay attention to my driving style while in a auto and leaving the romping to the bike. My wifes Venza has all kinds of gadgets in it and it's shown me a lot. It's amazing how if you get over a certain rpm range a vehicle really uses more fuel. I have also learned that cruise control isn't necessarily the best way to conserve fuel either.

On second thought, a vacuum gauge would be surely be good for a conventionally-carbureted engine.

I _think_ it would be useful for a fuel-injected engine, but I don't know enough about how the fuel/air mixture is managed to say for sure.

Watching your RPM's, going the speed limit, and slow acceleration. I get 26 MPG city, out of a car rated at 22 MPG by doing this, speed limit thing is the hardest. I get an extra 64 miles per tank. Which adds up when you drive 45 miles each way to work. And doing the speed limit in ATL is almost illegal.

I am sure there is a way to do a vacuum gauge, but I'm not sure personally.

On the driving style, I've tamed down somewhat in the car...but the bike is still a different story.

If I were solely worried about fuel mileage I wouldn't have gotten a AWD Surburban with the larger engine, but I wanted it for when I hook up to a trailer. I'm just wanting to help make it as efficient as possible, thus the request for anyone who has more expereince than I...which shouldn't be too hard

Do you absolutely need the suburban? honestly a 6.0 gasoline engine isn't ever going to get "good" gas mileage.

I drive and ride like I just stole the damn thing myself. One day I might slow down...Maybe.

Not really in the same category, but when I picked up my new anvil last weekend, I used my trailer to transport it.
On the highways, mileage sucks with one of those things, so I drove lower than the speed limit and instead just stuck behind a big rig.

Oh, and a 6.0 liter engine? (interesting that americans have accepted the metric system for engines )
That is always going to be thirsty no matter what you do.
My advice would be to sell it and buy something of which the mileage is measured in miles per gallon instead of gallons per mile

Do you really need a 6 liter engine? The reason I ask is that from time to time I have to pull a trailer with my 110 HP suburban car, and up to the legal limit for that weight class, it holds up fine. Even if your trailer is so heavy that you can't pull it any other way, you might be better off buying an economy car for when you're not pulling that trailer.

No, stick with big, but just get a Diesel engine. I love the family 4Bee4 with it's V6 diesel. Heaps of get up and go and great milage being diesel. I drive it like I stole it too. Just don't tell the wife (oh and I always take it easy when the kids are in the car too. )
