The metal-to-metal friction coefficients of push belt type CVT fluids with block-on-ring, ball-on-plate and element-on-plate tests were compared. Additionally, the effects of detergent-dispersant and anti-wear agents on the friction coefficients with block-on-ring and ball-on-plate tests were evaluated. As the results, it was found the good correlation between block-on-ring and element-on-plate test results. However, it was not found the correlation between block-on-ring and ball-on-plate test results. It seems that the ball-on-plate test results depend on the role of anti-wear agents in the fluid.
