   A number of poly tetra fluoro ethylene (PTFE) colloIdal suspensIons are being marketed In the country which claim to form teflon layer on engine cylinders when applied with crankcase lubricants, thus reducing engine wear and Improving fuel efficiency. This paper gives laboratory test results of a commercial additive with PTFE. According to the test results, no practical advantage has been achieved through the use PTFE additive on fuel consumption; In fact, It Increased the wear rate of engine
