Synthetic oils came about because every oil used in cars has an additive package in it to help it do it's job. Oil without these packages would only lubricate and not be very consistent as they heated. Eventually scientists figured out how to make synthetics that are less suceptible to heat and breakdown. as a result synthetics last much longer than the additive packages did and they are very consistent in viscosity throughout the temperature ranges they operate at. We started using them in jet engines back in the 1970's and it was amazing how much less wear we saw at inspection cycles.
The only drawback I have seen with them is that they are initially more expensive and, on an older engine with even minor leaks, synthetics will tend to leak as much or more from those areas.
The purpose of semi-synthetic oil is to provide a balance between the affordability of conventional mineral oils and the enhanced performance and protection of fully synthetic oils. Semi-synthetic oils aim to offer improved lubrication properties, better resistance to high temperatures, reduced engine wear, and extended engine life compared to conventional oils. They are designed to meet the needs of modern engines that require higher performance standards while remaining cost-effective for consumers. Overall, semi-synthetic oils aim to optimize engine efficiency and longevity in a variety of operating conditions. Types Of Semi Synthetic Oil: Semi-Synthetic Blend: These oils are a mixture of conventional mineral oil and synthetic base oils. They typically contain around 30-50% synthetic oil mixed with mineral oil. This blend offers improved performance and protection compared to conventional oils while remaining more affordable than full synthetic oils**.** Hybrid Semi-Synthetic: Also known as synthetic technology oils, these are formulations where the base oil is primarily mineral oil with some synthetic additives to enhance its performance characteristics. They provide better protection against high temperatures and engine wear than conventional oils but may not offer the same level of performance as a semi-synthetic blend.
Among Motorcraft oils, it would be the synthetic or synthetic blend 5W20 Among other oils, most synthetic blends and synthetics meeting 5W20 and 0W20 will meet it
Always use synthetic oils in BMW's.
Yes, you can even mix them.
It might be... It's highly not recommended to mix regular and synthetic oils.
There are available many semi- and fully-synthetic oils which are formulated for diesel engines.
The fastest-growing segment continued to be synthetic and synthetic blend lubricants
Who told you it is not recommended? You can mix synthetics as long as they are of the same weight. You can even mix synthetic with conventional oil.
Who told you it was not good? You can and should use full synthetic in a 150cc air cooled engine.
With most synthetic oils, the manufacturing company recommends changing every 3000 miles. Most of these oils, even the cheap off-brand will last up to about 4500 or 5000 miles.
It is a fake antioxidant used to preserve fats and oils in packaged foods.
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.
