Like a surgeon peering inside a patient, Caltex recently showed how engines that are fed with low quality fuels become dirty in no time. In contrast, the same test showed pictures of how an engine that regularly uses Caltex with Techron are kept clean and operating at optimum levels.

The results of the boroscope tests, a machine that is able to take videos and photos inside cars’ engines, were unveiled before local motoring media and members of the Car Awards Group Inc.  The tests involved 35 cars with at least 25,000 kilometers on the odometer or at least 3 years old. Pictures show build-up of unburned and harmful deposits in piston tops, and intake valves in engines that use fuels other than Caltex which is marketed by Chevron Philippines Inc. (CPI).

Jude Porras, Product Engineering Specialist, CPI, said, “Over time, deposits can accumulate in your car's combustion chambers. These deposits can cause knocking or pinging, run-on or reduced performance, particularly if your car has driven over 25,000 kilometers. Deposits on carburetors, fuel injectors and intake valves can cause your car to produce higher emissions, may begin to hesitate and stutter during acceleration, knock or lose power.”

In contrast, included in the test was an eight year old car with 107,000 kilometers of mileage consistently using Caltex scored a near perfect 9.8 in intake valve deposit (IVD) cleanliness scale of 1-10 based on rating from the Coordinating Research Council (CRC) in the US.


During the tests, cars with engines that showed valves, spark plugs and combustion chambers with heavy deposits were fueled with Caltex with Techron for five days . Boroscope tests were again conducted afterwards which showed significant gains in engine cleanliness. A car with a clean fuel system is more responsive than a car that is choked up with deposits.  Fewer deposits mean less chance of deposit-related engine problems.

Only Caltex has Techron, a powerful fuel additive based on the unique compound called polyetheramine (PEA) that works at the molecular level to prevent and clean deposits left behind by other fuel brands.  Other deposit control additives may clean the engine's intake system but contribute to combustion chamber deposits.  These deposits can cause an engine to need a higher octane fuel to avoid knock and run-on, or loss in performance. In contrast, Techron is not only unbeatable in fuel system deposit control, it also minimizes build-up of combustion chamber deposits.

Caltex with Techron gives motorists five benefits. First, is maximized power.  Test bench data shows that deposit build up in critical engine parts due to the use of inferior fuel can result to about six percent power loss. The Techron in Caltex helps clean up these deposits resulting to restoration of lost power.

Second, improved fuel economy because Techron removes performance-robbing deposits.  Cars  perform best when vital engine parts are kept clean.  Fuel economy is restored when deposits are removed from the fuel system. A clean engine burns fuel more completely, getting more energy from every drop of fuel, resulting in longer distances traveled.

Third, is lower emission. Caltex with Techron is proven to remove and protect engines against deposit formation in intake valves and port fuel injectors.  A ten year old car with 117,000 kilometers on the odometer fuelled exclusively with Caltex with Techron scored a very clean 9.2 out of a possible perfect 10 based on the intake valve deposit (IVD) rating by the Coordinating Research Council in the USA.
Fourth, is smoother drive.  Techron is especially formulated to make cars run the way it should. A clean engine ensures optimum combustion, reduces misfires and enhances drivability. A car with a clean fuel system is more responsive than a car choked up with deposits.

Fifth, is reliable performance. Techron’s unique chemistry is proven to keep valves clean even after 80,000 kilometers.  Caltex tested two 2.0l cars, one used Caltex with Techron while the other ran on a fuel without any additive. Although both cars started with an IVD rating of 10, after running for 80,000 kilometers the car on the fuel with no additive scored a dirty 7.5 while the car on Techron scored 9.8 IVD, almost as clean as brand new.

 “Caltex with Techron® is unbeatable at cleaning up and avoiding harmful engine deposits. And unlike the other deposit control additives, Caltex with Techron® cleans up both intake systems and combustion chambers,” added Porras.

Caltex is also completely free from harmful metal-based compounds commonly used to boost octane rating. Chevron's Fuels Technology Team conducts Detailed Hydrocarbon Analysis (DHA) using a gas chromatograph on gasoline samples to eliminate undesirable compounds in Caltex fuels.

Arnel Reniedo, Caltex Brand Manager, said, “Techron is standard in Caltex fuels such as Silver and Gold. Even our Caltex Diesel has Techron D especially made to keep fuel injectors clean in diesel engines. We do not scrimp on our customers. Whether you drive a car, an SUV or jeepney, Caltex with Techron gives you the five-star treatment. Continuous use of Techron will clean engines to provide motorists with the five benefits of Caltex with Techron.The 5-Star Fuel. ”

CPI also announced the “Caltex with Techron.The 5-Star Fuel” campaign which will be supported by on-ground efforts such as station merchandising and a radio campaign to air in major AM and FM stations in the Mega Manila, as well as in key cities nationwide.  The new campaign not only continues to reinforce the unbeatable cleaning power of Techron, but also illustrates the five important benefits a clean engine brings:  Maximised Power, Better Fuel Economy, Smoother Ride, Lower Emissions, and Reliable Performance.
