In order to research the significancy level and difference in different motor assistant’s oil saving, the randomized block test design is introduced. The two stage cross-over design is explained. The two stage cross-over design was realized using SAS and the test data were gained. The test data was analyzed using variance analysis. The oil saving level and sample difference are gained. The study in this paper can be adopted in other fields of test design and data analysis.
