More than years ago Chevron announced Techron, an engine cleaning additive that would improve the performance of cars and chevron vs shell‘s V-Power have compited ever since. Opinions are divided among users who are fateful to their favorite fuel. Both are good, there is no questions about it, but it is alarming that after 20 years, Chevron has not really said how effective the additive is.
Nobody knows what the additive really is but they claim that four or five tanks of Techron will clean deposits, valves and fuel injectors enhancing the performance of the vehicle. Newer engines need a cleaning fuel constantly as their engines have not that much tolerance for dirt and Chevron’s fuel with additive is the most sold in the US because, according to the research Centre of Chevron, their formula is the only one keeping the engine clean and the formula is patented and protected.
A few years ago, there was a huge marketing campaign led by Chevron that made consumers aware of the importance of a proper additive to keep clean the engine and sales went up. However, it is still not very clear if its popularity is due marketing or due to actual results, as no actual test are being perform to compare.
