Caltex looks inside engines in Asia

Tests reveal that most Caltex with Techron users achieve an average of 9.7 out of 10 score rating on the cleanliness of their engine intake valves.

Metro Manila, Philippines – Caltex’s latest boroscope test in Asia, conducted throughout 2013, has revealed the harmful effects that lower quality gasoline have on motor engines, while highlighting the cleaning proposition that Caltex with Techron offers as the ideal solution for motorists. The boroscope test utilized a specially designed camera to examine the interior of a vehicle’s fuel system to inspect the cleanliness of critical engine parts.

Caltex with Techron gasoline has been proven to be efficient at keeping intake valves cleaner based on such boroscope tests conducted on a total of 224 valves in the Philippines. Results from 32 vehicles tested in the Philippines showed that vehicles using Caltex with Techron performed well in keeping fuel systems clean, proving that its gasoline kept intake valves almost perfectly clean as compared to vehicles using lower quality gasoline.

“Motorists are often unaware of the state of their vehicles. The boroscope tests prove to local motorists that Caltex with Techron works in keeping their engines clean, contributing to better performance of the vehicle,” commented Greg Engeler, Chevron Product Engineering Regional Manager, Asia Pacific. “Chevron has spent more than 30 years in research and development to prove that the cleaning properties of our patented Techron technology not only works in laboratories and in the US, but in the Philippines as well.”

Using a Karl Storz Endoscope (boroscope), Chevron engineers took photos of intake valves and ports (via fuel injector hole) and rated them using a Co-operative Research Council (CRC) Intake Valve Deposit (IVD) rating system, where a score out of 10 was assigned, with 10 denoting a perfectly clean valve. Photos were also taken of piston tops (via spark plug hole) to assess combustion chamber deposits (CCDs).

Vehicles that used Caltex with Techron achieved an average score of 9.7 out of 10 in Philippines, surpassing the average score of 9.2 for vehicles using lower quality gasoline, despite achieving a higher odometer reading. Vehicles using lower quality fuels recorded the worst valve readings of 8, 6 and 7 out of 10, for Malaysia, Philippines and Thailand respectively.

The tests were performed on local vehicles using Caltex with Techron and vehicles using competitor or lower quality gasoline brands within the test markets. Vehicles selected represent a cross-section of the local market vehicle fleet in order to reveal an unbiased and true state of local motorists’ vehicles.

“The test alerted motorists to the hidden problems of their vehicles, such as harmful deposits that may cause issues down the road. Caltex fuel quality is good that’s why I typically have no problems with my vehicle engine,” said Jed Villapando, one of the Filipino motorists who participated in the test.

Chevron Philippines Inc., Product Engineering Specialist, Jude Porras said, “To perform at its best, your engine requires unrestricted air and fuel delivery which cannot happen when a vehicle’s intake valves and port fuel injectors are clogged. A clean engine ensures that your vehicle’s fuel-to-air ratio is optimized, allowing your vehicle to maximize fuel energy. Only Caltex has Techron, which cleans up both the intake system and the combustion chamber, allowing vehicles to maintain optimum performance and increase fuel mileage.”

All grades of Caltex with Techron gasoline contain Techron. Techron contains a polyetheramine component designed to clean up fuel system deposits and prevent them from reforming. Lower quality fuels can leave harmful deposits in the motor engine that accumulate over time, causing the vehicle to stumble during acceleration, knock or lose power.

One tank full of Caltex with Techron is effective at cleaning and protecting engines previously choked up with deposits. Continuous use of Techron will provide motorists with better fuel economy, maximized power, reliable performance, lower emissions and a smoother drive. Caltex with Techron combines patented technology, proven research and service quality for the evolving needs of motorists who expect more out of their fuel.
