If oil is dripping down your motorcycle’s tube, your vehicle’s performance will be affected. It won’t have as much power, and you’ll notice it acting sluggishly.
Pour-point depressants: This additive has nothing to do the actual pouring of your oil. In fact, pour-point depressants help prevent the wax particles in the oil from hardening in cold conditions. As a result, the motor oil flows freely even in low, cold temperatures and the engine doesn’t need to work any harder to pump it.
