Types of Oil for a 4.3 Mercruiser Engine
There are three kinds of oil suitable for the 4.3 Mercruiser engine: mineral oil and synthetic blend oil as well as full synthetic.
Mineral Oil
Mineral oil is the very traditional type of oil for engines which has been used for quite a while. It is made up of crude oil and enhanced with additives to improve its performance.
Mineral oils can be the cheapest type of oil, and are readily available. However, it’s not the same as synthetic oils in extreme temperatures or in engines with high performance.
Synthetic Blend Oil
Synthetic blend oil can be described as a mixture of synthetic oil and mineral oil. It has better performance than mineral oil and isn’t as expensive as full synthetic oils. Blend oil made of synthetic is suited to most engine types which include the 4.3 Mercruiser engine.
Full Synthetic Oil
Fully synthetic oil is produced completely from chemical compounds and doesn’t include any oil that is crude. This is by far the most expensive kind of oil however it provides the highest performance, particularly when it comes to extreme temperatures and high-performance engines. Fully synthetic oils are the most sustainable option because it emits less carbon dioxide.
Choosing the Right Oil for Your 4.3 Mercruiser
When selecting the appropriate engine oil to suit your 4.3 Mercruiser engine, you must consider these factors:
Owner’s Manual Recommendations
The owner’s guidebook for your boat will give you recommendations regarding the kind of oil that you can use to your engine. It is essential to adhere to these recommendations to ensure your engine performs optimally.
Viscosity
Viscosity describes how thick the engine oil is, and is determined by the system of rating. The number of viscosities you require will be based on the conditions you operate in as well as the condition of the engine. Refer to the owner’s manual of your vehicle for the recommended rating for viscosity.
Additives
The addition of oil additives to the engine can enhance its performance and also protect against wear and wear and tear. Find an oil that has additives suitable to marine engines, for instance, anti-wear and anti-corrosion additives.
