Benefits of using AMSOIL for your semi truck lubricants
On a semi truck, 25,000 miles go by in a flash. Normal preventative maintenance intervals can cost owner-operators and companies thousands in downtime and extra expenses, and every few years the engine still needs to be rebuilt. AMSOIL can make all the difference for drivers and fleet managers who want to keep their trucks running longer and with lower routine service of semi truck lubricants, not to mention staving off repairs for months or years longer.
What motor oil is best for long-haul trucks?
For a fleet manager, breakdowns away from home are the worst-case scenario – to be avoided at all costs. For decades, conventional 15W40 motor oil was seen as the best option to protect heavy-duty diesel engines and keep them in good working order. In cold weather, 5W40 was often preferred due to a lower pour point, but it left engines more exposed to wear over time. Today, the best diesel engine oil is fully synthetic, and it’s much better at protecting a truck’s engine from the carnage that tends to happen with millions of miles.
AMSOIL has several grades of Signature Series Max-Duty Synthetic Diesel Oil including 15W40, 5W40, 0W40, 5W30, and even 20W50. By using AMSOIL in diesel engines, you can get your truck back on the road fast and keep it there.
Signature Series Max-Duty with 6X's more protection
We know AMSOIL truck lubricants are the best engine protection your money can buy, but don’t just take our word for it. Third-party testing shows Signature Series Max-Duty Synthetic Diesel Oil delivers 6X more protection against wear than required by Detroit Diesel’s® standard.*
*Based on third-party testing in the Detroit Diesel DD13 Scuffing Test for specification DFS 93K222 using 5W-30 as worst-case representation.

Benefits of using AMSOIL® semi truck synthetic lubricants
Better protection against soot
It’s not even close. Compared to the other best diesel engine oil brands, AMSOIL controls diesel engine soot the best, preventing abrasion on metal components. When soot levels are high, regular diesel engine oil carries soot particles to moving parts where they defeat the purpose of the oil’s protective barrier. AMSOIL protects the engine’s metal parts by encapsulating soot particles and carrying them away to be filtered out.
Better fuel economy
AMSOIL’s truck lubricants provide top-notch service, helping to prevent wear and tear, as well as increasing fuel efficiency by up to 3%. Any fleet manager knows how fast that adds up! It’s due to lower internal resistance to flow, measured by the oil’s viscosity, which is gauged by the oil viscosity, leading to less fuel being used to power the truck. With these benefits in mind, any fleet operator looking to maximize their MPG should certainly consider using the best synthetic diesel engine oil. Who wouldn’t love a few more MPG on semi-trucks in their fleet?
Less engine oil consumption
Do your semi trucks tend to burn oil between oil change? That’s considered normal. An engine can consume as much as a gallon of the best diesel engine oil between oil changes, but AMSOIL’s exceptional capacity to lubricate prevents gouges in cylinder walls and wear on piston rings, and also better seals the gap between the two. The result? Up to 38% less engine oil consumption, so don’t be surprised when you check the engine’s oil and other truck lubricant levels.
