The importance of a good engine oil
Valvoline engine oil is much more than just a lubricant: it protects, cleans, and extends the life of your engine. Proper maintenance and timely oil changes are key to ensuring optimal performance and durability for your engine.
In marine diesel engines, oil plays an even more critical role due to the demanding operating conditions on board vessels. Humidity, salinity, long periods at sea, and high temperatures make using quality lubricants essential for properly protecting all internal engine components.
Regular Valvoline oil changes help prevent premature wear, overheating, and performance loss in marine engines used in recreational boats, fishing vessels, marine generators, and other marine applications.
With over 150 years of experience in lubrication, Valvoline is synonymous with quality, innovation, and advanced protection. That’s why more and more professionals and repair shops trust its products for all types of engines—from industrial vehicles to marine machinery.
The Valvoline range of lubricants is designed to offer excellent protection both in coastal navigation and on vessels subjected to intensive offshore work.
When should you change your Valvoline oil?
The ideal time to change Valvoline oil depends on several factors: the type of machine, the conditions in which it operates, and the type of oil used.
In marine engines, in addition to the number of operating hours, it’s also important to consider factors such as operating temperature, type of navigation, and the stress the engine is subjected to during each outing.
Many people wonder how often to change 5W-30 synthetic oil or how long Valvoline 5W-30 synthetic oil lasts in marine engines. The answer can vary depending on the type of vessel and the conditions of use, although it’s always recommended to follow the engine manufacturer’s instructions and perform regular preventative maintenance.
In general:
- Every 10,000–15,000 km if using a synthetic oil such as Valvoline 5W30.
- Every 5,000-7,000 km if using semi-synthetic oil or if the vehicle is operating in demanding conditions (extreme temperatures or heavy loads, for example).
- Once a year, even if the recommended mileage has not been reached, to prevent oil degradation.
In addition, it is always advisable to check the oil level and color from time to time. Dark oil or oil with metal residues is a sign that it has lost its lubricating properties and needs to be replaced.
How to change your oil with Valvoline, step by step
Performing the change correctly ensures maximum engine protection. These are the basic steps followed in professional workshops such as Talleres Nasio:
- Warm up the engine slightly for a few minutes to facilitate the drainage of used oil.
- Remove the oil pan plug and drain the old oil into a suitable container.
- Replace the oil filter, as it accumulates impurities and residues.
- Pour in the new Valvoline engine oil, using the amount and viscosity recommended by the engine manufacturer.
- Check the level with the dipstick and start the engine for a few seconds to ensure that the system is properly lubricated.
- Check for leaks and clean up any debris.
An oil change carried out with quality products and under the supervision of a specialist prevents premature wear and optimizes fuel consumption. That’s why we recommend you visit our workshop so that your boat’s engine is always in the best hands.
How long does Valvoline 5W30 synthetic oil last?
Valvoline 5W30 oil is known for its excellent thermal stability and superior resistance to degradation, even under extreme conditions.
However, the lifespan of Valvoline 5W30 synthetic oil depends on:
- The type of marine engine.
- The operating hours.
- The engine’s workload.
- The operating temperatures.
- The quality of the fuel used.
- The vessel’s general maintenance.
In marine engines subjected to intensive use, regular oil checks allow for the timely detection of potential contamination or loss of lubricating properties.
