Valve pinging

Valve pinging
Yesterday I was going over a small hill so I pressed the gas a bit (enough to go up the hill) and the engine was pinging. This reminded me of my former car when I ran regular instead of middle grade.
Has anyone else experienced this, or do I have a bad tank of gas?
It has no-name brand (Crown) gas in it right now. I have a hair under 3K miles on the car.

Re: Valve pinging
I haven't experienced any pings or knocking using Shell Gas.
Here's a link to Top Tier Gasoline site which cites benefits of using brands which adhere to its principles - unsure of affiliation so be aware this is probably biased.

Try Shell or another National Brand next fill-up, still using 87...

Abward,
I can't imagine a situation were this pinging would be considered normal. I would report this to your dealer and take them for a drive if you can duplicate the noise. Even if you had "bad" fuel, the computer should be able to retard the spark enough to stop pre-detonation. By identifing the possible problem, you may save a big bill later on.
