Product Highlights View Full Description

Exceeds both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements. Provides outstanding performance in pre-2007 diesel engines in on-road applications as well as all model-year diesel engines in off-road apps. Also recommended for gasoline engines requiring API SL or previous specifications.

AMSOIL 10W-30/SAE 30 Synthetic Heavy Duty Diesel Oil is formulated with premium synthetic base oils that exceed both 10W-30 multi-grade and SAE 30 straight-grade viscosity requirements for outstanding performance in modern and older diesel engines. Unlike conventional SAE 30 motor oils, AMSOIL Heavy Duty Diesel Oil has a naturally high viscosity index and does not contain paraffin (wax). It has a low pour point and qualifies for SAE 10W, making it an all-season multi-grade lubricant with a wide operating temperature range. AMSOIL Heavy Duty Diesel Oil is formulated without viscosity index (VI) improvers. This shear-stable formulation is designed to reduce viscosity loss and associated bearing and cylinder bore wear. AMSOIL 10W-30/SAE 30 Synthetic Heavy Duty Diesel Oil contains premium additives with a high 12 TBN to neutralize acids from blow-by, exhaust gas recirculation (EGR) and high-sulfur diesel fuels. It helps protect against damaging piston deposits, ring sticking and sludge.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API qualified synthetic motor oil back in 1972. Trust the extensive experience of AMSOIL The First in Synthetics® to do the best job protecting your equipment.

Performance
Where these viscosity grades are specified, AMSOIL 10W-30/SAE 30 Synthetic Diesel Oil provides outstanding performance as a straight-grade SAE 30 for older two- and four-stroke diesels and as a multi-grade SAE 10W-30 in modern four-stroke diesel and gasoline engines. AMSOIL Synthetic Heavy Duty Diesel Oil is ideal for use in a wide variety of light- and heavy-duty applications, including agriculture, offroad construction, trucking, mining, industrial (pumps and generators) and personal automotive or commercial transportation. It is recommended for use with low or high-sulfur diesel fuels in standard, turbocharged or supercharged engines; all off-road engines and pre-2007 on-road engines.

  • SAE 10W-30 performance without VI improvers
  • Cost-effective replacement for conventional oils
  • Excellent shear stability
  • Outstanding wear protection
  • Superior protection over a broad range of operating temperatures
  • Extended service life

I have been running this oil for seven years. I ran it in a fleet of 125 Generators, 25 Loaders, and 40 Kenworth semis. I never once in 3 years had an engine failure. These pieces of equipment ran around the clock in the oil fields. Our generators would run 26,000 Hours before we would bring them in for a rebuild. We would take them out of service for a rebuild, the engines never failed. I would reccomend this product to anyone and I would put it against any other oil on the market. I run it in all my personal vehicles and engines. I will be an amsoil customer for life.

Comments about SAE 15W-40 Heavy-Duty Diesel and Marine Oil:

We have been using this oil in our diesels for over 8 years and it has never let me down. We had a fleet of 150 gensets and 50 semis. Not once did we have an engine failure due to lubrication qualities with this oil. Our engines in the gensets lasted 26,000 hrs before we would pull them out of service to rebuild. I have used this oil in my personal diesel pickups and have never been disappointed. I will run this oil for life.

Comments about SAE 15W-40 Heavy-Duty Diesel and Marine Oil:

We have a diesel Pusher motorhome and since using this product I figure my engine (Cummins) runs smoother and cooler, along with the extended mileage, it is a no brainer for performance and cost savings overmore frequent oil changes. I installing a By Pass filter to clean the oil even more than the stock filter does, My coach has a Allison Transmission so that gets the 'TORQUE DRIVE " Synthetic oil and the rear end has the 80/140 oil too. Nothing but the best for us for sure.

Using this product in my trawler

By 

from Seattle, WA

Verified Buyer

Comments about 10W-30/SAE 30 Synthetic Heavy-Duty Diesel Oil:

Used this product in a Westerbeke 4 cylinder diesel engine in a sailboat for a number of years. 100 hour standard oil change interval. With this product I changed the filter every 100 hours and the oil at 300 hours. Oil test/analysis indicated the oil was still good at 300 hours. Now I use it in an American Diesel (Ford Lehman) 6 cylinder industrial engine in my trawler. 200 hour standard oil change interval. I changed the standard oil filter every 200 hours and the oil at less than 600 hours (1 year). Oil test analysis at 493 hours indicated the oil TBN was 8.8 and oil was still good. This allows me to operate my boat all summer in remote locations from Tacoma, WA to Juneau, AK without having to change oil.

Comments about Series 3000 5W-30 Synthetic Heavy Duty Diesel Oil:

Was having some stiction issues with my 7.3. Was recommended this product by an oil specialist. Never heard of Amsoil before I used it. Seemed like my engine loved it as I could tell that it started right up and seems to have restored any loss of power. Stiction seems to have gone away even in cold start ups. Will exclusively use this product.
