Pour Point Depressants — Understanding how they help motor flow better

How pour point depressants help oil flow better in cold weather Pour point depressants are additives used in engine oils to improve fluid flow at colder temperatures. They work by inhibiting the formation of wax crystals that can occur in oil when temperatures drop below a certain point, effectively lowering the temperature at which the oil will still flow properly (the “pour point”). Most modern conventional and synthetic engine oils already contain suitable depressant additivess to allow flow down to around -20°F to -40°F. So DIYers don’t need to worry … Read More
