The results delighted our scientists. The strictly controlled programme of tests at an independent laboratory revealed that Shell Helix oils rapidly remove sludge from dirty engines. The oils also keep on cleaning the engine components and rendering dirt harmless until it is removed with the oil at the next oil change. This is important, as it prevents sludge removed from one area being deposited elsewhere in the engine.\u003C/p\u003E\r\n\u003Ch4\u003EStandard Industry Test Vs Shell’s Clean up Test\u003C/h4\u003E\r\n\u003Cp\u003EStandard industry tests only measure an oil’s ability to keep an engine clean. We wanted to show that Shell Helix oils can actually clean a dirty engine by removing sludge. We worked with South West Research Institute, Texas, USA, to develop our own clean-up test, which is much tougher than the industry keep-clean test. Our test uses the standard industry test (Sequence VG) as a basis, but modifies it by adding oil-change cycles.\u003C/p\u003E\r\n\u003Cp\u003EA clean V8 engine was run for a long period, approximating to an oil-change interval, using mineral engine oil. The engine was dismantled at regular intervals to enable the scientists to record the sludge build-up on key engine components, including the rocker cover and the valve decks. This is when a standard industry test would finish.\u003C/p\u003E\r\n\u003Cp\u003EAfter this period, when the engine would normally be serviced and the oil would be changed, the mineral oil was drained off and replaced with Shell Helix oil. The test was continued for a similar time, with the engine being dismantled at regular intervals so that the amount of sludge could be recorded.\u003C/p\u003E\r\n\u003Ch4\u003EThe Results\u003C/h4\u003E\r\n\u003Cp\u003EThe test was repeated for different Shell Helix tiers and their counterparts. The results for Shell Helix HX5 are typical: an immediate clean-up effect, and the engine continuing to get cleaner until the end of the test. The cleanliness of the different engine components was recorded, and the same clean-up effect was seen to occur with the change to Shell Helix throughout the engine.\u003C/p\u003E\r\n\u003Cp\u003EThis demonstrates that the sludge removed by Shell Helix is not redeposited, but remains in suspension where it is rendered harmless until it is removed at the next oil change.\u003C/p\u003E\r\n\u003Cp\u003EWe also have world-leading engine- and vehicle-testing technology, including 25 chassis dynamometers, 40 test beds with environmental temperature control ranging from –40 to +50°C and more than 300 fleet vehicles.
