Test result: When the spot test to three to be replaced. Generally speaking, oil is more tough motorcar 3 such conditions occur, such as the location there, said 3 oil quality has deteriorated seriously, the proposed deposition ring and owners have deep color with diffuser ring, diffuser ring has been Changing the oil while narrowing. This can better retention money, merely likewise aid stretch engine life.
oil spots on the test:
oil spot test is a test of the oil test method has been discontinued. However, the operability of this method are relatively lusty, simple and intuitive,
Lacoste Trainers 2011, and cheap cost, there is some technological foundation. More importantly, this test method is more for the mean owner is easy to operate, without identification of mysterious wisdom.
