The World Cat Federation has also adopted this classification, treating the color point Short hair as a distinct breed. Many Siamese cats from Thailand had a kink
Pour point depressant oils contain polyaromatic hydrocarbons and resins which act as antagonists against synthetic pour point depressants. Pour point depressants are also ineffective for engine oils with a viscosity above SAE 30. Generally they are most effective on thinner oils like SAE 10, SAE 20 or SAE 30 grade oils. Alkylaromatics and aliphatic polymers are two types of pour point depressants that are commercially available. Most commercially available pour point depressants are organic polymers, but nonpolymeric substances such as phenyltristearyloxysilane and pentaerythritol tetrastearate may also be effective. In 1981 there was a problem with lubricating oil pumpability. The same thing happened the
