I was told by a GM mechanic not to use gasoline with techron because it will clog the injectors. He said most GM cars and trucks have this problem ( I had a chevy pickup at the time). Does anyone know this to be true? I only use Chevron gas. Could I be causing a problem by not mixing the different brands? </div></BLOCKQUOTE>
Ok, there are smart techs, and those that think they are smart. GM's additive for fuel injector cleaning uses Techron in a pretty high-solution.
I can tell you a story of Saturn researching fuel injector cleaning additives back in the 90s, for not only injector cleaning but top head cleaning, and after extensive testing, Techron was chosen.
Saturn used this additive for quite a few years, and finally, GM finished their testing, and went with the same additive. Just have to watch some of the additives sold at the auto parts store, since some contain such a small amount of Techron that the additive is worthless.
Many believe (sorry no proof), that running Chevron fuel with Techron helps to clean the fuel level sensor and helps to prevent the problem with the fluctuating or totally inaccurate fuel level indication, caused by sulfur in the fuel. Again, this is all speculation, but there are a lot of Vette owners who swear by Chevron and Techron.
I myself when possible, used Chevron in the Vettes.
I would tell the technician to reference GM's bulletin #04-06-04-047E, that lists the Top Tier fuel suppliers as researched by GM and a few other auto manucturers (BMW being one of them) (Info - TOP TIER Detergent Gasoline (Deposits, Fuel Economy, No Start, Power, Performance, Stall Concerns).
This bulletin applies to all year GM vehicles, and the first supplier listed is Chevron. As we all know, Chevron's primary addtive for fuel unjection and top head cleaning is Techron (they own the patent).
What is TOP TIER Detergent Gasoline?
TOP TIER Detergent Gasoline is a new class of gasoline with enhanced detergency. It meets new, voluntary deposit control standards developed by four automotive companies that exceed the detergent requirements imposed by the EPA.
Who developed TOP TIER Detergent Gasoline standards?
TOP TIER Detergent Gasoline standards were developed by four automotive companies: BMW, General Motors, Honda and Toyota.
Why was TOP TIER Detergent Gasoline developed?
TOP TIER Detergent Gasoline was developed to increase the level of detergent additive in gasoline. The EPA requires that all gasoline sold in the U.S. contain a detergent additive. However, the requirement is minimal and in many cases, is not sufficient to keep engines clean. In order to meet TOP TIER Detergent Gasoline standards, a higher level of detergent is needed than what is required by the EPA. Also, TOP TIER was developed to give fuel marketers the opportunity to differentiate their product.
Why did the four automotive companies join together to develop TOP TIER?
All four corporations recognized the benefits to both the vehicle and the consumer. Also, joining together emphasized that low detergency is an issue of concern to several automotive companies.
What are the benefits of TOP TIER Detergent Gasoline?
TOP TIER Detergent Gasoline will help keep engines cleaner than gasoline containing the "Lowest Additive Concentration" set by the EPA. Clean engines help provide optimal fuel economy and performance and reduced emissions. Also, use of TOP TIER Detergent Gasoline will help reduce deposit related concerns.
Who should use TOP TIER Detergent Gasoline?
All vehicles will benefit from using TOP TIER Detergent Gasoline over gasoline containing the "Lowest Additive Concentration" set by the EPA. Those vehicles that have experienced deposit related concerns may especially benefit from use of TOP TIER Detergent Gasoline.
