Yes, it says premium. I changed it to regular for the past 3 years and
found no pinging, running well and I do not do fast start.
The fuel pump relay was changed about 4 years ago. Doubt it comes bad that
quick. The original lasted about 12 years. Also, will the fuel pump relay
cause the check engine code to lid on?
Thanks.
K.S.

The car doesn't say "premium fuel only"?
I thought all 2.3s did. (not that this has anything to do with your engine
shutting itself off, the fuel pump relay is still the #1 suspect there)
