Whats up all. I am wondering what the best mpg you guys have got with your 2nd gen GS. Make sure to specify year and whether its a GS3, GS4, or GS430. The best I have ever gotten was 27 mpg in my '99 GS4.

 

To a full tank of gas I get about 365 miles

 

Lets see, with the 27 mpg tank, that was 530 miles for the full tank.

 

i've got an '03 GS3, and my last tank (80% city driving) got me 340 miles.

 

wow 530 on a GS4...I get 300 on a full tank with my 00 GS3. I'm assuming those were highway miles on a road trip.

 

Well, I drive roughly 20 miles to work one way, and that lasted me almost two weeks. I'd say abour 430 of thosemiles were highway, the rest were city. Let me also mention, for gas mileage purposes, I was going no more than 55 on the highway just to get up to that number of miles. Yeah, its slow, but it definitely saves on gas. I would never go on a long road trip and go so slow. The time difference for a 20 mile drive between 55 and 80, which is what I normally drive, is not too noticeable. However, when I drive from Jacksonville to Miami, that difference would add hours to the drive - not something worth saving a little gas money.

 

How in the world did this happen? haha... i have an '03 GS3 & i get about 260 miles on a full tank.

 

Driving habits bro.

I got about 305 miles on a full tank. '00 GS3.

 

here's my May record for gas for my GS400

I got 30mpg that one day b/c I spent the entire day on the highway.

 

My best is like 19 mpg and 290 miles a tank. How do you guys get such good mileage?

 

I guess I do it by not flooring it all the time. I have no idea. Maybe the car likes me. Lol.

 

Its all about where and how you drive. You get better mileage on the highway and even better mileage if on the highway you go 55. Yes, it sounds slow, however, you lose 10% of your fuel efficiency for every 5 mph over 55. Think about going 80 - a reasonable speed on a large interstate. Thats 25 mph over 55 - or 50% less fuel efficiency. If the drive time difference is not that significant, buckle down and go slower. No flooring the gas pedal and sending the RPM's into the red. If you can keep your RPM's under 2500, you are in awesome shape and you will improve your gas mileage.

 

I try not to go over 3K RPM's, but I don't think I could ever go slower than 70 on the highway. Haha.

 

It is tough. It all depends on how far you have to drive. On short distance drives, the time difference is not noticeable. However, like I said before, I couldn't do 55 when making the trip from Jacksonville to Miami - it would add whole hours to the trip.

 

I still couldn't do it, even if it was just a 5 minute drive. If it's a short distance, I tend to drive faster too. It's just another habit of mine.
