Automotive oil agency, how to choose for their own oil type

 Q: My car plus the promise of your oil, how noise bigger? How power as before? A: Sorry, we do not recognize this is the first engine noise, each engine has its own characteristics, different from other engines have their own voice, if you have not ruled out the psychological effect confirmed, then there are several Reasons: 1, first make sure the engine sound bigger after cold start or when the vehicle enters the normal condition, if it is cold start loud, we recommend using the promise of low-temperature start of better products, which is the front of the engine oil viscosity grade W The smaller the number of products. 2, if the vehicle enters the normal operating conditions of the engine sounds great, make sure the promise is being used for other brands of oil temperature viscosity engine oil temperature viscosity specifications consistent with your previous label is not used, if the viscosity of 40 has been used before, then suddenly Use oil viscosity of 30, there will be bigger engine sound phenomenon, it is because the engine running resistance becomes smaller, the sound will naturally become excited. 3. If you select a lower viscosity oil power shortage occur simultaneously, it is because the oil before using poor abrasion resistance, engine gap is too large, low-viscosity oil is not guaranteed cylinder pressure, we recommend the use of high-viscosity oil recovery . 4, if the promise is consistent with the use of oil and oil viscosity used before, and the engine sound bigger, because we promise to four oil base oil (PAO) higher levels for oil products, the higher the content of PAO engine louder, it sounds more excitement, Mobil is a typical representative of the other brands, the higher the four base oil content, the better the long-term nature of oil, your car engine performance will be better release.
