The quality of engine oil is important for the correct work of the car. Today the wide range of the similar liquids differing first of all in the structure is presented at the market. For this reason interests many that oil synthetics or semi-synthetics is better. To make a right choice, it is necessary to consider the following information concerning a car: age, brand, run and technical condition.
What oil is better - synthetics or semi-synthetics?
For a start it is necessary to consider features of each oil that will allow to make a choice for any given option.
- Synthetic oil. First of all the difference between oil of synthetics and semi-synthetics consists in molecular structure and in the first case it is developed in such a way that allows to maintain big loadings. Still this option can brag of excellent resistance to temperatures and various chemicals. Features of synthetic oil consist in an opportunity to keep viscosity irrespective of temperature. It is possible to refer to advantages also good wear resistance. It is also worth noting high rates of fluidity that allows to get to oil to the most hard-to-reach spots of the engine. For high quality of synthetic oils it is necessary to pay a high price.
- Semi-synthetic oil. The similar product is received thanks to addition in synthetics of mineral substances. At the same time there are no certain restrictions and ratios in similar mixes therefore each producer experiments with structure on the discretion. 40% of synthetic and 60% of mineral oil are most often used. Speaking about in what oil synthetics from semi-synthetics differs, it is worth noticing that the last cannot be used at low temperatures as even already at-10 degrees the consistence becomes dense. One more minus is that a small amount of additives causes high risk of emergence of oxidizing processes. Many stop the choice on this option as such oil is more available at the price.
Whether it is possible to mix synthetics with semi-synthetics?
One more topical issue which interests many drivers. Experts say that mixing of synthetics and semi-synthetics is a bad decision as motive work can significantly worsen. It is connected with the fact that these liquids contain different amount of additives. For this reason it is possible to mix liquids only when there is no opportunity to get suitable oil. At the same time it is worth noticing that mixing it is possible to make only if at oils identical brands.
Transition from synthetics to semi-synthetics?
If you decided to replace a type of oil, then it should be taken into account that the molecular composition of semi-synthetic oils at different producers differs therefore it is worth trying to find the most acceptable option.
That there was no mixing of oils, it is important to carry out the procedure of replacement correctly. It is necessary to try to merge as much as possible liquid, but even, despite this on walls of cylinders everything, there is a number of oil. As not to avoid mixing, it is recommended to choose means of the same producer. By the way, it should be considered also that whom interests whether it is possible to add synthetics in semi-synthetics.
Experts upon transition to different brands recommend to carry out full washing of the engine. The similar service can be received in any automobile service, it is also possible to make everything and the hands. For holding a procedure it is worth buying special oil for washing. It should be filled in in the engine.
