Why I Swear by 15W40 Full Synthetic Diesel Oil
As a long-time diesel engine owner, I have experimented with various types of oils for my vehicle. However, nothing has impressed me quite like 15W40 full synthetic diesel oil. It has become a necessity for me and here’s why.
Firstly, the 15W40 designation indicates the viscosity grade of this oil. This means that it has a high resistance to thinning out at high temperatures and thickening at low temperatures. This is crucial for diesel engines as they operate at higher temperatures and require an oil that can withstand it without losing its protective properties.
Moreover, being a full synthetic oil, it is made up of highly refined base oils and additives that provide superior protection to my engine. It offers better lubrication and reduces friction, which in turn leads to improved fuel efficiency. This results in cost savings in the long run.
Another reason why I consider 15W40 full synthetic diesel oil necessary is its extended drain interval. Unlike conventional oils that need to be changed every 3,000-5,000 miles, full synthetic oils can last up to 10,000-15,000 miles depending on the manufacturer’s recommendation. This not only saves
