听说除了PAO的，其他都可以混。我觉得PAO应该也没事儿。

听说一旦换成合成油，都不能再换回一般机油，所以不要混用。
把剩下的一堆先用了完再换。 |

high mileage的机油会使gasket膨胀，据说最好是用了之后就一直用HM的。

Is it ok to switch back and forth between regular and synthetic motor oil? I
heard this causes leaks? Is this true?
Switching between synthetic and conventional oil does not cause problems.
Because the oils are compatible, you can switch back and forth as often as
you like.
Can you mix different types of motor oil? For example, synthetic and
synthetic blend or regular and synthetic? Is this going to cause problems?
Mixing synthetic and conventional oils will not cause any problems. The oils
are compatible with each other.
How does SynPower compare to Mobil1 and Amsoil?
Valvoline's SynPower motor oils meet and exceed the same specifications as
these two products.
SynPower motor oils are high performing, high-quality oils formulated with
full synthetic base oils and top tier additives to provide an increased
level of performance. All of Valvoline's SynPower motor oils are API
licensed to ensure quality for North American vehicle application. We have
specially designed SynPower 5w40 for application in high performance
European or diesel passenger cars and this oil carries the specific OEM
approvals such as Mercedes Benz, Volkswagen, Porsche and BMW. Our North
American SynPower 5w20, 5w30 and 10w30 exceed ILSAC GF-4 requirements and
carry the API starburst on the front label. SynPower is designed with extra
levels of detergent and antioxidant to provide outstanding deposit and heat
protection.
Why are synthetic oils more expensive? Are they worth the extra cost?
Synthetic oils are superior to conventional oils because they help maximize
horsepower, improve gas mileage and provide a smoother, cooler operation for
the engine, prolonging engine life. Many vehicle owners feel that the
benefits of using a synthetic motor oil are worth the extra cost.
Does using synthetic oil create more sludge?
No. Synthetic oils do not increase the chance of sludge. Valvoline motor
oils are 100% anti-sludge guaranteed.
Does using synthetic oil cause my car to use more oil?
No. Synthetic oils do not increase oil consumption.
Does using synthetic oil damage engine seals?
No. Synthetic oils are perfectly safe for all rubber seals.
I heard that synthetic oil is too thin for use in an older car and creates
blow-by and burn-off. Is this true?
This is only true if the blow-by problem exists prior to using a synthetic
oil. If you have a leaking or blow-by problem, synthetic oils can make the
issue worse, but they do not cause it to happen. |
