Hi guys, I've owned a used 2006 Hyundai GLS now for about 5 months, love the car just wish the fuel mileage was a bit better.

With gas prices the way they are, and me only working part time, I've been trying to save gas, my top highway speed is now 60 MPH, I put 40 PSI in my tires, I skip the drive thrus and go inside, I often coast in neautral coming to a stop light,and accelerate as slow as I can you can call me a hypermiler. Straight highway, If I clear the trip computer I get 34 MPG at 60 with the AC on, mixed its about 30-32 MPG. I changed my air filter a short while ago, I have my oil changed at the dealer, currently have around 31k miles I'm doing for a tranny service soon.

The car has great power and a great set of brakes, I've personally topped 140 in my Sonata just for kicks. What type of fuel mileage do you get with yours? Some times I'm kinda regretting not getting the V6, if I would have bought the car today I would have probably gone for a 4 cylinder, but 5 months ago gas was high but my expectations on fuel economy were good and I had no clue the gas prices were going to climb this high. I would love to drive the car and great gas mileage, but for a 6 cylinder you have to play nice to get the mileage out of it.

Ive considered using 5W20 synthetic, but I have one more free oil change from the dealer, I believe they use Quaker state dino 5w30 bulk.

 

I think most of it is driving habits. I have the V6 also and you really have to drive nice to get the gas mileage. I recently did an air intake mod. PM me and i'll give u details.

 

From my own experience, your driving habits have a HUGE affect on fuel economy. Speeding up to a redlight is just a waste of gas. If you know you have to stop, why accelerate and then brake hard. Let off the gas and coast up to the light. Many times you will come to a stop without using the brakes at all or by the time you have to use your brakes, the light turns green and you only have to accelerare lightly.

Also, using cruise control on the highway and lowering your speed. Cruising at 55-mph instead of 65+ saves fuel. Many don't realize that the original 55-mph speed limit was done in the 70's not for safety but to save fuel during the first gas crisis. Bottom line, slow down and save fuel.

 

I have an 06 and i ger great gas mileage, I use cruise control alot when on the highway, I usualy fill up once a week.
