Product Description
AMSOIL Synthetic 10W-30/SAE 30 Heavy Duty Diesel Oil (ACD) 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 ACD has a naturally high viscosity index and does not contain paraffin (wax). It has a -33°F pour point and qualifies for SAE 10W, making it an all-season multigrade lubricant with a wide operating temperature range. AMSOIL ACD is formulated without viscosity index (VI) improvers. This shear-stable formulation is designed to stop viscosity loss and associated bearing and cylinder bore wear. AMSOIL Synthetic 10W-30/SAE 30 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 protects 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 Synthetic 10W-30/SAE 30 Diesel Oil (ACD) 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 diesels as well as gasoline engines. AMSOIL ACD is ideal for use in a wide variety of light and heavy-duty applications, including agriculture, off-road 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 with oil analysis

MIXING AMSOIL
AMSOIL ACD is compatible with conventional and synthetic motor oils, however, mixing AMSOIL ACD with other oils will shorten the oil life expectancy and reduce the performance benefits. AMSOIL does not support extended drain intervals where AMSOIL ACD has been mixed with another product.

Aftermarket additives are not recommended for use with AMSOIL ACD.

SERVICE LIFE
AMSOIL Synthetic 10W-30/SAE 30 Heavy Duty Diesel Oil (ACD) is recommended for extended drain intervals in engines that are unmodified and in good operating condition.

Diesel Engine Service:

• Three times (3X) OEM* recommendation, not to exceed 50,000 miles/600 hours or one year, whichever comes first. Drain intervals may be extended further with oil analysis.

• Severe Service - Up to 15,000 miles or one year, whichever comes first, or longer based on oil analysis.

Gasoline Engine Service:

• Two times (2X) OEM* recommendation, not to exceed 15,000 miles or one year, whichever comes first.

*Operating conditions and drain intervals for severe and normal service are defined by the OEM. Refer to your owner’s manual.

Note: Extended drain intervals are not recommended when using biofuels containing >10% ethanol or 5% biodiesel (B5). Follow OEM drain intervals or extend drain intervals with oil analysis.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

The value of a Classic.

Greetings,

I have a 2001 Hummer H1 and I recently 'rescued' a 1995 Hummer H1. Now, both of these vehicles are
getting closer to the Classic status. I am bringing the 1995 back to life. I have changed the diff oil, hub oil, engine oil, trans oil, and coolant with Amsoil. The 1995 is running strong now.

I take the vehicles out in the wilderness. I see no reason to risk my family getting stranded by using a cheap/sub-standard product.

Adventure on!

Excellent product!

I've been using Amsoil 15W-40 Heavy-duty Diesel and marine oil in my 2006 Silverado 2500HD for 10 years now. Oil and filter change intervals average around 12,000 to 18,000 miles.
The truck now has over 355,000 miles on it and it still runs great! I never have to add any oil between oil changes either. If you are on the fence about using this oil in your vehicle, I say, go for it! You won't regret it!
Amsoil is top of the line!

15W40 Heavy Duty Diesel Oil

I have an 06 Dodge with the Cummins. These 'older' diesels required a CI4+ oil. There is much debate in the oil world about the qualities of the newer oils vs the older ones - specifically that the old CI4+ oils had more detergents in them, which the older engines liked better. Even though the newer oils are backwards compatible, they apparently do not have the same detergents in them. This has been the only CI4+ rated oil I can still find. Its the only oil I use in the Cummins.

The best oil.

I maintain seven vehicles so changing oil could be a full time job. I use Amsoil because it is the best oil made and the best filter in the industry. My twin sons just became 16. For their birthday I had them learn how to change the oil in their trucks by converting them to Amsoil . This oil seems to be better suited to my older VW Jetta than the other Diesel oils. I use less of this oil. My car has nearly 300,000 miles and has always used about 4 oz of oil every 500 miles. With this oil that amount is cut in half.

Using this product in my trawler

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.

The perfect oil for our 6.0 Powerstroke, and for yours also

Our 6.0 diesel is in a Ford E450, 2006 cutaway-motorhome, mileage just over 130K-we purchased the rv new. As the chassis is just about 3,000lbs from being maxed out I do change oil more frequently than the recommended 5k miles and went to full synthetic at about 1,000 miles-my change interval is just about 4,000 miles give or take.
For the first year I used either two of the big names in diesel oil and had to top off with between 1 to 1 1/2 qts between changes. Tried Amsoil after seeing cases and cases of it at an engine builder that I was sent to for a service call.
I started with AME 15-40 Heavy Duty Diesel/Marine and Amsoil got my attention when I began to realize that I was NOT adding oil between changes. After two years or so I decided to try ACD 10/30 30 Heavy Duty Diesel and was amazed at the quicker starts and the very different sound of the engine BUT I will admit to being somewhat concerned with the lighter oil when summer arrived. The hot weather arrived well ahead of schedule and while I did not have to add oil one thing did change , I was getting just under 2mpg better with ACD oil.
And I know what some are thinking because it was the way I was thinking-the engine was getting broken in and this explained everything; so I switched back to one of the others and I switched back to adding oil and loosing the extra mpgs- I changed back to Amsoil and the engine changed for the better. I have done this four times and each and every time the improvements came back when Amsoil came back-nothing else was different but the engine oil.
Become a preferred customer and total cost should be in line with what you are paying now.
Regardless of what diesel engine is shaking your truck give Amsoil a try-it made a huge difference for me and it will for you also I am convinced of this.
