Last October, Caltex conducted a borescope test on vehicles in the Philippines and other Asian countries, comparing different engine intake valves of vehicles using Caltex fuels and that of other brands. The test utilized a Karl Storz borescope to examine the inside of a vehicle’s engine intake and then comparing it against the industry standard Co-operative Research Council (CRC) Intake Valve Deposit (IVD) rating system, where a score of 10 denotes perfectly clean.
Now, the results are finally out.
From the hundreds of tests done, it shows the big difference when vehicles use Caltex fuels compared to other lower-quality fuels. To be specific, the tests showed an average of 9.7 out of 10 score rating in Asia and 9.8 out of 10 in the Philippines on the cleanliness of engine intake valves when Caltex with Techron and Clean & Glide technology fuel is used. Meanwhile, vehicles using other low-quality fuels recorded an average of 8.9 of out 10 in the region with some vehicles even scoring as low as 5.0.
“The recent borescope test once again helps demonstrate to local motorists that not all fuels are created equal. Since our last test in 2013, Caltex fuels continue to work at keeping parts clean, thereby contributing to five performance benefits – maximized power, better fuel economy, lower emissions, a smoother drive, and reliable performance,” says Greg Engeler, Chevron’s product engineering manager for Asia Pacific.
Aside from showing the effect of different fuels, the borescope test also demonstrates Caltex’s commitment to cleaner engines while staying true to the evolving nature of Techron in anticipation of future engine technology and local market needs.
“We are extremely proud of the borescope test results as these provide concrete evidence of the consistent performance of Caltex with Techron. Achieveing such a high score in valve cleanliness reflects our commitment to providing only the best-quality fuel products,” says Chevron Philippine Inc. country chairman Louie Zhang.
All grades of Caltex gasoline sold in the Philippines now contain Techron, a fuel additive package backed by more than 30 years of research and development. Meanwhile, the new Clean and Glide technology is designed to clean up deposits in the fuel system and prevent them from reforming.
