Think a 5W-30 Diesel Engine Oil Can’t Protect Like a 15W-40?

Guess again. Series 3000 100% Synthetic 5W-30 Diesel Oil is one of AMSOIL’s most powerful engine oil formulas. Despite being a 5W-30, this synthetic diesel oil is designed to provide wear control that is equal to or greater than 15W-40 diesel oil, while maximizing fuel economy. HDD 5W-30 is formulated to deliver extended service capability of up to 3 times the oil change interval suggested by your owner’s manual. For the duration of these long intervals, AMSOIL 5W-30 synthetic diesel oil withstands extreme heat and heavy loads.

AMSOIL HDD is suitable for applications requiring the API CI4+ specification and older specifications released prior to CI4+. It is not suitable for applications requiring the API CJ-4 specification and is not compatible with late-model exhaust treatment devices.

Less Oil Changes Saves Time and Money

AMSOIL makes no compromises in the formulation of HDD diesel 5W-30. A powerful additive package disperses soot, fights acids and keeps diesel engines clean over exceptionally long drain intervals. This saves down time, maintenance costs and reduces waste oil. While you may never push HDD 5W-30 to its maximum service life, it’s nice knowing that your diesel engine oil is capable of going way beyond normal drain intervals.

Synthetic Diesel Oil for Maximum Miles per Gallon

The idea behind this synthetic oil is to offer a light 5W-30 weight to optimize mileage, while packing it with anti-wear additives. The result is a synthetic diesel oil that minimizes friction while improving wear control compared to regular 15W-40 diesel oil. Many years and millions of hard miles have proven the HDD 5W-30 concept to be a no-compromise success. Save money with improved mileage and extended drains.

Maximum Wear Control

Despite being a 5W-30, HDD does not sacrifice wear protection. AMSOIL loaded this formula with an anti-wear additive package that provides wear control that we proudly stack up against any 15W-40. The elite synthetic base oil delivers shear strength and steady viscosity protection, regardless of horsepower output, heavy loads or extreme heat.

Clean Engine Formula

To develop a synthetic diesel engine oil with extended drain properties, special attention has to be paid to soot control and overall clean engine internals. AMSOIL HDD Diesel 5W-30 is loaded with detergents and dispersants that keep soot in suspension. A clean diesel engine runs efficiently and performs to its full potential while keeping soot-related wear at bay.

Minimal Oil Usage

Some might assume that a 5W-30 synthetic diesel engine oil would go right through the engine and out the exhaust? HDD 5W-30 users find the opposite to be true. AMSOIL HDD 5W-30’s synthetic formula is designed to withstand oil “burn off” and “thinning out” in the face of extreme heat and heavy loads. The result is a diesel engine oil that maintains its level and its original viscosity for continuous protection.

Unrivaled Cold-Start Protection

We’ve covered AMSOIL HDD 5W-30’s remarkable hot weather protective properties, but as you can well imagine, a synthetic diesel 5W-30 oil is also quite beneficial in cold weather. With a cold-pour point of -50C (-58F), expect instant and complete engine protection upon start-up, regardless of the temperature.

HDD 5W-30 Synthetic Diesel Oil Applications

Mixing AMSOIL Synthetic Diesel Oil with Other Brands

AMSOIL HDD 5W-30 Synthetic Diesel Oil is compatible with all other brands of conventional and synthetic engine oils. While you can safely mix AMSOIL Synthetic Oil with other brands, this will reduce the drain interval and performance capabilities of AMSOIL oil.

The use of any aftermarket oil additives is definitely not recommended.

Service Life

AMSOIL HDD 5W-30 Synthetic Diesel Oil is recommended for extended drain intervals in unmodified, mechanically sound diesel and gasoline-fueled vehicles.

Diesel Engine Oil Life Recommendations

Up to three times the oil change interval as recommended by your owner’s manual. Must not exceed 50,000 miles (80,000 km) or 600 hours or one year, unless backed with oil analysis.

Note: When using 5% biodiesel (B5), follow the manufacturer’s oil change interval or support with oil analysis.

Gasoline Engine Oil Life Recommendations

  • Normal Service(1) – Up to 25,000 miles (40,000 km) or one year, whichever comes first.
  • Severe Service(2) – Up to 15,000 miles (24,000 km) or one year, whichever comes first.

(1) Personal vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.
(2) Turbo/supercharged engines, commercial or fleet vehicles, excessive idling, vehicles with more than 100,000 miles (160,000 km) without prior continuous use of AMSOIL motor oil, daily short-trip driving less than 10 miles (16 km), frequent towing, snow-plowing, hauling or dusty condition driving.

Note: When using gasoline with an ethanol content of greater than 10%, follow the manufacturer’s oil change interval or support with oil analysis.
