Q: I religiously read your Sunday newspaper column right after Dilbert. I keep getting emails about EcoMax, which appears to be a plug-in device promising 15-35% less gas consumption. Is this a viable $49.95 investment?

A: I am glad that Dilbert shares the column with you. Do you piously read it while in church? Too-amazing-to-believe fuel saving devices are the work of the devil. Avoid the temptation.
