Premium vs Regular on 2.0L

The inside of the gas cap door recommends Premium. The Owners Manual threatens warranty problems if you don't use premium. Buick Service gives a long political non-answer.

What do you think?

I read page 298 of the owner's Manual...only if engine knocking occurs can you not use 87 octane...then 91 is suggested. Yes, performance/economy may not be as good with 87, so it says, but don't see it mentions a warranty problem.

Never noticed knocking...been using 87 octane for 8,900 miles, in pretty close to sea level Texas.

I'm more of a "just listen to the owners manual and gas cap" kinda guy. If it calls for 91, then use 91. The engine operates optimally with that octane level and it ensures no issues in the sense of knocking and what not.

I heard if you have turbo engine then you're best to use higher octane?

Dealer told me that it's a "recommendation", not a "requirement". If regular is used it won't violate warranty or cause any issues. Might just notice it being a little less performant and fuel efficient.

Reading the owners manual, the primary recommendation is to use TopTier fuel.
Octane 87 only becomes a problem if engine knocking occurs.
Other than that it seems like a trade off between performane/economy and price.
Here in north Texas you'll pay around $2.19 for 87 octane while 93 octane is around $2.69.
I've been using 87 octane and have no complaints with performance or economy.
How much impact does premium fuel really have on economy (other than my finances)?

From the Service Manual:

"Use premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 91 or higher. Regular unleaded gasoline rated at 87 octane or higher can be used, but acceleration and fuel economy will be reduced, and an audible knocking noise may be heard. If this occurs, use a gasoline rated at 91 octane or higher as soon as possible. Otherwise, the engine could be damaged. If heavy knocking is heard when using gasoline with a 91 octane rating or higher, the engine needs service."
