improved gas mileage

[nextcar]

Well, my Genny 4.6 now has 17k miles, and i noticed an improvement in the MPG.
For example, last year, I drove to Las Vegas and back, round trip about 500 miles, and got 27 MPG.
Just made the same trip, and it read 28.5 MPG.

Recently, I used a loaner Sonata with the 2.4 L motor. During 5 days of commuting to and from work, I averaged 25.5 MPG.
Now that I got my Genesis back, doing the same commute, I'm getting 24.5 MPG.

I think my Tau 4.6 has finally broken in, and I am damn impressed by how efficient this engine is!
Especially considering that it doesn't have direct injection, 8 speeds, start/stop, or cylinder deactivation.

Have other V8 owners noticed improvement in gas mileage after 15k miles?

Yes, maybe 1-1.5 mpg improvement in mixed city/hwy.

very nice.

considering that these regular gas 4 cylinder midsize cars don't save that much gas, i don't think we should feel very guilty about driving our V8s.

I also noticed an improvement, somewhere around 22,000 miles. I was getting between 21 and 22 (mostly city with a little highway) and now I'm getting between 23 and 24.
