Semi synthetic or fully synthetic oil?
Synthetic oils are specifically manufactured to provide consistent, superior performance. Their main advantage over petroleum oil is that they protect the engine across a far wider range of temperatures – up to an engine’s maximum temperature and beyond. They do not have the impurities found in petroleum oils or degrade as quickly, and they are thinner, helping to improve fuel efficiency.
FULLY SYNTHETIC OIL – As the name suggests, fully synthetic oils are purely synthetic with no petroleum oil. They offer the highest levels of performance and are an essential requirement for many modern engines (check your handbook if you’re unsure of the requirement for your car).
SEMI-SYNTHETIC OIL is less expensive than fully synthetic as they are a mixture of synthetic and petroleum oil. Engines requiring semi synthetic oil must use at least semi synthetic oil (not petroleum oil) but may benefit from upgrading to fully synthetic oil for increased protection and performance.
EURO SPECIFICATION SYNTHETIC OIL – European automobile manufacturers design vehicles to use specific high quality lubricants with specific properties and additives. Well over 90% of API-Licensed motor oils offered on Americans retail shelves do not meet those demanding ACEA specifications, and the European lubricants are not readily available. Those that are available are typically hard to find, and quite expensive. As a result, vehicle owners, quick-lube shops and even dealerships use standard American-market petroleum oils. This lets problems such as premature engine wear and engine sludge develop which can cause complete failure in some engines as early as 40,000 to 50,000 miles! Here at SEAE, we only use Euro Specified Synthetic Oil recommended by the manufacturer.
