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.

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

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.

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.

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).

Tend to trust AmsOil

This weight oil sounds a bit to light for a worked hard off road machine, but it's what the AmsOil gurus recommended so that's what I run!

Like the price and quality

The Viscosity works well in my 41 year old 500 CI Cad motor. Has enough phosphorus for my lifters.
I also can use it in my mower that requires a straight 30 wt.
Been using this for the last 10 years and I am very pleased with the results. Zrod would also be a
good choice, but this has a higher base number...

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.
