Better Mileage Since 30k Service

[lambobaby1218]

So I've noticed that I'm getting 2 mpg better since I've had my car serviced at 30k. Believe it or not, I'm getting 30 mpg. I do drive a lot freeway. Okay, something just occurred to me. Maybe it's because it's the holiday week and there's not a whole lot of stopping-and-going??? Anyways, I'm just trying to figure out why I would be getting better mileage........NOT THAT I'M COMPLAINING!!!

The best I've gotten in my IS350 was 28mpg.. that was 75mph and on cruise control...

Then right when I get off the Interstate.. it drops down to 15-19 MPG fast...

After 13,500 miles.. my overall is around 18...

My average speed is between 75 and 80. When I drove 65, just for the heck of it, and to test out the mpg, I got about 32 mpg. I do use the roads often, not just highway. But I guess the highway evens it out.

I think you get a new engine air filter at 30,000. That might help some.

I'll guess they checked and then increased your tire pressure a bit.

If they changed the oil and your air filter, that's not surprising.
