When Progressive talks about oil level, they are refering to excessive levels, like 3-4 inches high or low. Honda recommends a level of 5 inches for an 1800 and progressive lowers that by a half inch due to their larger springs displacing more oil. Lowering the oil level by a half inch or even an inch will have no affect. Lowering too much and you will cavitate on large bumps(air in oil) and the suspension will be very mushy. Too high a level will creat a hyd lock on compression and blow the seal.
