The change volume of the oil due to differnce in temp.
For example, if one litre of oil is heated from 45 deg C to 55 deg C, the quantity of oil at 55 deg C, 1007 Milli litre, then the co seeficeint of thermal expansion of this oil is 0.0007cc/cc/deg C
0.2
There is no difference in viscosity. A 10w30 full synthetic is the same as a 10w30 blend.
10w40 semi synthetic
Either full synthetic or standard primary oil.
No they shouldn't be mixed as they have different viscosity Actually, yes you can......but you are wasting your money. Mixing the two reduces, significantly, the positive effects of the synthetic oil. Only do it if you have to, but they are compatible. There are oils available that are a synthetic blend of standard oil and synthetic oil.
SAE 30 full synthetic.
Synthetic motor oil is generally considered to be superior to natural motor oil. Production of this oil requires man made chemical compounds that are mixed with specific additives that help reduce friction and improve viscosity.
20/50 weight. That is all that is recommended.
Most synthetic motor oils are not truly man made, being both a blend of petroleum based oil and synthetic oil. Synthetic oils are not necessary better for your car, but are better for the environment. Whichever you choose, pick an oil that matches the viscosity specified by your cars manufacturer.
engine oil is 5w-30 but it actually depends on the climate where the vehicle is at. you can go higher or lower viscosity. i preffer synthetic oil..
Yes but I would not mix these as the viscosity is not the same.
The recommended oil for a 2002 Toyota Corolla is a high quality 10w30 multiple viscosity. Synthetic oil is also acceptable and recommended.
