I've heard Techron is the best cleaner on the market, but that was a few years ago. I pretty much stick to Top Tier Gas and haven't had to get fuel injectors cleaned on any of my vehicles yet, even though they were all used when I got 'em. Now the Z28 I just got has almost 140,000 miles on it (and 17 years of who-knows-what) so may need the injectors cleaned. If that occurs then it shouldn't be an issue later.
