Product Description
AMSOIL OE Synthetic Diesel Oil provides excellent protection and performance in both on- and off-road diesel engines for the original equipment manufacturer’s recommended drain interval. It is a licensed API CJ-4/SN motor oil suitable for both modern and older diesel applications, including those equipped with turbochargers. AMSOIL OE Synthetic Diesel Oil exceeds the higher performance demands of modern engines and withstands the stress of heat, soot and acids to help prevent deposits, wear and corrosion.

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

Meets Emission System Requirements
AMSOIL OE Synthetic Diesel Oil is a low-sulfated ash formulation that meets the requirements for low-emission quality diesel oil and protects under the most severe conditions found in modern diesel engines. It is compatible with all exhaust treatment devices and is designed for engines equipped with diesel particulate filters (DPF).

Extreme-Temperature Performance
OE Synthetic Diesel Oil is formulated for improved heat and oxidation resistance over conventional petroleum oil for cleaner engine operation, maintaining power and fuel efficiency for superior engine performance. Its dependable cold-temperature flow assures easier start-up and improved engine protection.

Resists Oil Consumption and Emissions
Due to its low rate of volatility, AMSOIL OE Synthetic Diesel Oil is able to reduce oil consumption and emissions during operation. It maintains its excellent film strength even during high-temperature operating conditions to ensure dependable protection, performance and fuel efficiency.

Controls Soot Thickening and Wear
AMSOIL OE Synthetic Diesel Oil is formulated with premium synthetic base stocks and robust detergent/dispersant additives that keep soot particles from agglomerating and forming larger wear-causing particles. The OE Synthetic Diesel Oil formulation allows for optimal protection, maintaining performance by staying in the respective viscosity grade.

COMPATIBILITY
AMSOIL OE Synthetic Diesel Oil is compatible with conventional and synthetic motor oils. Mixing AMSOIL motor oils with other oils, however, will reduce the performance benefits.

Aftermarket oil additives are not recommended for use with AMSOIL motor oils.

SERVICE LIFE
AMSOIL OE Synthetic Diesel Oil is recommended for the intervals stated by the original equipment manufacturer (OEM). Refer to the owner’s manual for the specific oil change interval. Replace the oil filter at each oil change as specified by the OEM.

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).

All around usable oil.

I was looking for 10-30 for my BBC 492, and seen this. I noticed that it will be replaced but still, I wanted to try it out. I have been using AMSOIL in all my vehicle's and various weights to see how they work. I'm well aware that this one will work fine just have try it out.

Will run with this oil.

It's makes my engine run cooler, stronger and smoother. The longevity between oil changes is one of the main reason that got it. The other my engine runs really good with it.

A devoted Amsoil user

Purchased this oil to change the oil in a Farm Tractor that I recently purchased. It is a Kubota 6cyl and holds 14 quarts of oil. In my opinion, Amsoil is the best oil on the market.

Noticeable Improvement

I never gave much thought to how much one brand of oil could differ from another of equal weight. My 6.0l diesel ran quieter, smoother and I dare say more efficient. I'm hooked.

excellent oil for old pushrod gassers as well

I stick to 10w-30 OEC for my flat tappet motors.
This new AMSOIL formulation gives me about 5psi more than 5W-40 Rotella T6 and about 8psi more than 0w-40 Rotella T5 at hot idle.
Even though it's rated 10w, the cold pour is similar to most 5W and 0w synthetics, and its high TBN & viscosity at 100 spec out great.
Should be outstanding at resisting shear & fuel dilution, time will tell.

Re: excellent oil for old pushrod gassers as well

Thank you Chip. AMSOIL has formulated the Z-ROD Line of oils in 10W-30 and 20W-50 for older flat tappet engines. These formulations have a higher content of ZDDP. This meets API SL and earlier specifications. For racing applications look to AMSOIL Dominator. Replied by Tech Admin
