What Do You Fill Up?

[GenesisDan]

Hey all, the whole time I drove the 3.8 Track (my previous car) I filled up 92 Premium.
I just bought the 2013 Genesis Sedan. Another V6 and am considering doing the same again.
I'm still running on the free tank the dealer filled up.
I didn't really see much of a mileage increase with my Track, at least my mileage wasn't any better than everyone else so I'm wondering if it's even worth it or should I save my $.30 a gallon?
What do you guys fill up, has anyone tried Premium/Regular and seen a difference?

I use regular. Get between 20-22 around town 28-30 highway.

I think I'll be going the same route then. I can't see the Premium making much of a difference as I didn't feel like I gained anything from it on the Track.

I have a non-GDI V6, but I've always used regular.
I don't think there in any advantage to using premium in the V6, GDI or not.

93

92 - have never used regular so couldn't tell you if it makes any difference. I think the specs say you get like 9 more HP in the rspec...

Yes, I've felt obvious real-world differences in every vehicle I've owned, for decades. Some respond more, others less, but all gasoline engines are more responsive, need less attention, and yield better mileage with more octane, better detergents, and less ethanol. It's just a fact. The only time I ever read or hear anything different among car enthusiasts is in online forums

I've use both 87 and 91 with my 4.6 and can't really see any difference in performance.

Nothing but 87 since purchase in May 2010.
The fact that the car uses reg gas is one of the reasons for my purchase of the V6.
