I don't understand people who buy an expensive performance car and worry about the cost of fuel. Find a car that takes low grade fuel, drive it and if you like it buy that car.

I’ve read about these engines and it seems that these 4-cyl turbo’d engines are prone to pre-ignition. Because of this, they are prescribed a special oil to help with that. I would think if you’re putting lower octane in your car, it would only make the condition more favorable for pre-ignition. Lower octane gas combusts easier than the higher octane gasoline. This is why your race gas has 98 - 110 octane. I always, always, always put 93 octane in with no ethanol. The last thing I want to do is put my Stelvio at risk for pre-ignition and engine problems.

I’d like to try race gas, but at $9.75/gallon it’s a bit prohibitive 😉. It WOULD smell nice though!

I’ve used 110, one time at a 1/2 mile timed event and the difference was noticeable but not remarkable. I’d stick with 93 if available.

Nah...pre-ignition is beyond easy for the computer to kill. Part of why response off the line isn't as good though.

Only speaking for myself....it's being cheap.

Very rarely (less then 10 times total) I have put regular gas in the car. Generally because I figured wrong and have to add a few gallons to get home....and just can't stomach paying .30 or more per gallon even at regular.

I'm lucky to be in an area with the cheapest gas in Ca pretty much + I'm cheap + kinda hate giving money to gas companies, taxes, businesses in LA that aren't selling me food...etc....so sometimes I put in $5-10 in cheap gas to get home, then I fill up with good stuff.

280 HK and MPG

Hi
Have a new Stelvio 280 HK and have about 1170 miles om the meter.
Have driven the car the most in the city but 16 MPG is a bit too much according to me.
In total, with a little highway, it is currently at 18.4 MPG.
What consumption do you have?
I only use Shwll V-Power 98 octan

I only use 93 octane Tier 1 gas. I if worried about the price of gas I would have purchased a cheap low performance car. Happy with the gas milage better than my Honda Pilot that I traded and while I pay more for gas I go farther on my dollar. Get 22 to 28 MPG with average of 24

Same as Pete. Around 23-24 mpg in mix of city suburban driving. One of my favorite cars was the last Volvo XC90 with the Ford modified marine V8 engine. Best mpg I ever got was 19 mpg.
