Surely wouldn't call it a performance car

It doesn't perform any better than any other v6 sedan I've owned, just costs more to put gas in it.

Car guys. How important or necessary is it to use high octane gas in a Lexus IS

Use the 85 and let us know how it goes

Although at higher altitudes you can get away with lower

Right, but stick with the "names" regular, mid-grade, premium and you'll be good

Correct. Regular at sea-level is like 87 and up here in the mountains its 85.

Shouldn't be a problem in a lower end performance vehicle like that.

Course doesn't it change with your elevation (as far as what octate in needed)?

I think that's right, but I've heard the elevation where it

Pasadena

I have heard 5k ft. as well. I live at 6k so I get 85 when my car calls for 87

Some cars are also adjusted for high elevation.

With modern engines, you shouldn't hear any pings or knocks if you don't
