FortNine collaborated with a laboratory to evaluate the impurities inside various engines of different motorcycles. They chose various motorcycles from around the world for this test. To check for the impurities inside the engine, they did not check the actual engine but collected the used engine oil dumped by these motorcycles.

The used engine oil was tested for impurities and small particles, which are caused mostly during the manufacturing process. Laboratory tested the samples of the used engine oil to get an idea.

Samples from 12 manufacturers

FortNine collected samples from at least 12 brands. These are collected at the random. The brand of motorcycles includes Royal Enfield, BMW, KTM, Yamaha, Kawasaki, Honda, Triumph, Suzuki, Harley-Davidson, Aprilia, Ducati and Yin Xiang.

The tests did take a long time. In fact, it took seven months. Interestingly, the results show that the Royal Enfield engine is the cleanest. The engine is cleaner than that of the BMW, Honda, KTM, Kawasaki and more.

How the lab tested the oil?

After collecting the used engine oil, the lab then filtered it to collect the impurities. The smallest particle collected by the lab was as small as 5 micrometres while the largest ones were about 100 micrometres big. The origin of these particles remains unknown.

The lab did try to find out the origin of the bigger particles. However, since the particles were fused together due to the extreme heat in the engine chamber, it was difficult for the researchers to pinpoint the exact origin. However, the reading was very consistent for the impurity of all the particles of all sizes.

The impurities in the engine oil include parts like carbon and metal shavings. However, the findings suggest that there are many more uncommon impurities such as cloth fibres, sand, plastic, chips of wood and many others. The researchers tested a 100 ml sample for the quality of the engine oil and the presence of carbon content too.

According to the test, the Royal Enfield motorcycle engines are the cleanest in the world. It has come as a big surprise to many. However, the quality of the Royal Enfield motorcycles has become much better than it used to be a few years ago.
