Some of you may be familiar with this article, but it appears that it is best to switch gasoline brands at certain intervals to minimize deposit buildups.

The author says he works for the largest gas retailer in the world, has 28 patents, and his specialty is gasoline additives. He has invented some for his employer.

My twenty five yeas of brand loyalty is saying this is bunk.

I would not be quick to dismiss a Ph. D’d organic chemist with Mr. Johnson’s credentials who has worked for Exxon/Mobil for around 2 decades, whose specialty is gasoline additives. He has done objective lab and field testing of all additives. One of my professors had his earlier career working for Exxon, and they constantly tested all of their competitors products (the best ones). His specialty was lubricants, and he admitted that they were never able to match the leaders in the field. Once they acquired Mobil, their quest was over.

If you paid attention to his lists of possible fuels to switch between, the only gas additive that was common to both lists was Techron (used in both Chevron and Texaco fuels in North America). I have done NO controlled, scientific testing of detergent additives, but BMW and Porsche have both recommended Techron by name in their owners manuals in the past. Since additive packages have progressed so far, I am not aware of any manufacturers that currently recommend supplemental additives.

If I had to use only one brand of gas, it would probably be Chevron. But I see no reason to ignore Mr. Johnson’s advice to switch between Chevron/Texaco and another company’s additive to most thoroughly remove ALL types of buildup.
