AMS OIL Truck and Travel Trailer

Engine Cleanliness

Engine cleanliness is a vital factor in maintaining performance and prolonging the life of a vehicle. This product comes with a boosted detergent and dispersant package. These additives work together to dissolve sludge and deposits, keeping the engine's internal parts, such as the crankshaft, clean and free from build-up. This prevents clogging and ensures that oil circulates freely, optimizing engine performance and efficiency.

Durable Viscosity

Viscosity, or the thickness and flow of oil, is crucial for engine protection. The 10W30 viscosity rating means that the oil is designed to maintain a consistent flow at various temperatures. This durable viscosity ensures that the oil continues to lubricate and protect engine parts even under severe driving conditions. The syn oil formulation helps the oil to resist breakdown, keeping its viscosity stable over time. Another durable and popular oil viscosity is AMSOIL 5W-30 High Mileage, due to its popularity with older vehicles. Whether in hot summer or freezing winter, the oil performs consistently, preventing wear and prolonging engine life.

Older vehicles often struggle with increased oil consumption. This synthetic oil for older cars and trucks has been engineered to tackle this issue. It offers a unique chemistry that helps control oil consumption by maintaining proper oil levels in the engine. By using this product, vehicle owners can enjoy a smoother ride without the constant worry about checking and topping off the oil.

Leak Protection

One of the standout features of this product is its seal conditioners. Older vehicles' seals can become hard and brittle, leading to leaks. The seal conditioners in this oil rejuvenate these aging seals, keeping them flexible and preventing leaks. This ensures that you won't lose oil and risk overheating, particularly vital for those driving in rural areas where service stations may be sparse.

API Licensed

Being API (American Petroleum Institute) licensed is a mark of quality assurance. This certification signifies that this synthetic motor oil meets the rigorous standards set by the industry. Vehicle owners can trust in the product's quality, knowing that it complies with the requirements for performance, protection, and compatibility with various engines.

Versatility in Various Driving Conditions

Whether you're navigating city traffic, cruising on the highway, or exploring rural landscapes, this premium oil offers the tailored protection that your vehicle needs. In the city, the enhanced anti-wear additives protect the engine from constant stop-and-go stress. On the highway, the guaranteed protection for 12,000 miles or one year ensures continuous performance over long distances. In rural areas, the minimization of leaks ensures that you can travel off the beaten path without worrying about losing oil and overheating, which will give confidence with doing a synthetic oil oil change on your high mileage vehicle.

As vehicles age, the demand for maintenance and high-quality lubricants increases significantly. One of the most pivotal moments in an automobile's life is when it crosses into the realm of "high mileage," typically around the 75,000-mile mark. It is at this point that the new AMSOIL High-Mileage Synthetic Motor Oil steps in, offering a superior solution to a problem that plagues older engines: sludge accumulation. The above chart shows how this product has been proven to reduce sludge in an effective way! Read on to learn more about what is high mileage engine oil from this premium engine oil company.

The issue of sludge is more than a mere inconvenience; it is a direct threat to the performance and longevity of an engine. Sludge forms when the motor oil in an engine breaks down due to high temperatures, contamination, and oxidation over a long period of time. It coats the engine's internal surfaces with a sticky, tar-like residue, obstructing oil passages and preventing the engine oil from lubricating and cooling the engine effectively. If not addressed, it can lead to decreased performance, higher fuel consumption, and ultimately, engine failure, which can cost up to thousands of dollars in repair. Fleet mechanics and engine mechanics all know too well the detriment sludge can bring to a vehicle's engine, and therefore the benefits of using "syn oil".
