Synthetic oil is a chemically made substitute made from petroleum components as opposed to non synthetic which is made from crude oil.
There is no difference in viscosity. A 10w30 full synthetic is the same as a 10w30 blend.
Yes, that is what a synthetic blend is that they sell.
20w-50 indicates Synthetic-oil
The difference between plastics and elastomers is actually quite simple. Plastics are made from oil and elastomers are made from synthetic material.
Why would you want to go back to a non-synthetic oil. Synthetic oil's are far superior to non-synthetic oil.Hope This Helps.AnswerNo, todays oils are compatible and it won't hunt anything changing back and forth
High milage motor oil has extra additives which help prevent oil leaks.
That's okay.
It is always best to use the oil recommended by your vehicle manufacture. If you are considering the difference between Synthetic oil and Conventional (pumped from the ground); if your owner's manual says to use synthetic, you need to use synthetic. But if your engine was designed around conventional, then you can upgrade to synthetic. Synthetic has advantages as being better at cleaning and protection your engine, but if you have a higher mileage vehicle, synthetic can cause leakage of the gaskets and oil seals.
Yes, gear oil is normally much heavier and is non-detergent.
Synthetic and conventional oil can be mixed and used with no problem. That is exactly what a synthetic blend that you can buy is. A mix of synthetic oil and conventional.
Yes, although don't expect damage to be immediate. Petroleum oil is refined and synthetic oil is engineered. The difference being the molecular structure is unstable and varies in petroleum oils. Synthetic oil has a more stable molecular structure that is less susceptible to shear stresses. I use Amsoil in particular, because it outperforms all other synthetics, but ANY synthetic is better than conventional. If your mfr requires synthetic, for sure do not compromise!
