My first post here.
Just bought a 2006 RL.
My wife wants to use regular gas. Besides performance,
is there a down side to using regular rather than premium?
I know, Acura says premium. Will this tell the computer
that this customer used the wrong gas and that voids the
warranty? With modern engine management systems these days,
I would think the car would be OK with regular or
am I killing the car?
Any thoughts?
Or please direct me to a thread that might have discuessed this before.

There is a thread that discusses the issue.
My recollection is that not only performance but gas consumption also will change (more) with a net value of close to zero.
I don't think the EMS can detect octane but might remember how often the knock sensor retarded the timing and don't know if ultimate or enough damage would result to trigger a warranty claim.

 

If the price of gas is an issue, then why buy a car that the mfg indicated the use of Premium Fuel.

Why not split the difference and at least use middle grade!

 

Welcome to AZ! There have been many threads discussing this issue. This is the last one....
