- Premium API CJ-4 Synthetic 5W-40 Diesel Oil (DEO) – 17 OCT 2012: I put 17,954 miles on this oil in just under a year. I took an oil sample (see Oil Sample #1 on the Oil Analysis page) prior to draining it and switched to:
- Synthetic Heavy-Duty Diesel & Marine Motor Oil SAE 15W-40 (AME) – Certain modifications were made to my truck to facilitate running this as a “Trial” – I do NOT recommend running this oil in 2007+ DPF equipped vehicles. Furthermore, I do not recommend running the DEO oil above any longer than OEM recommended drain intervals on 2007+ Dodge, Ford, and Chevy Diesel trucks, unless oil analysis indicates otherwise.
- Severe Gear 75W-90 Gear Lube (SVG)
- Synthetic Multi-Vehicle Automatic Transmission Fluid (ATF) – Transmission and Transfer Case.
- Diesel Fuel Additive Concentrate (ADF)
- Cold Flow Improver (ACF) when appropriate
*Diesel Owners: If you live in the northern states where you routinely see cold temperatures and maybe even temperatures cold enough to cause the fuel to gel I recommend using the Diesel Concentrate Plus Cold Flow Improver (DFC) to save a little bit of money.

SAE 0W-20 Signature Series 100% Synthetic Motor Oil (ASM)
- 02/09/2012 – Please note, this is no longer a recommended oil for this vehicle. I am not sure why and have sent AMSOIL Technical Services an email inquiring if it was removed by mistake or if there are other problems with using the 0W-20 in that motor. I will update when they respond.
- 02/10/2012 – Update! Just as I expected, the removal was to better assist you, our customers, to break down the cost, drain interval, and oil specification barriers by matching each specification to their correct viscosity grade per OEM recommendation. If you are still confused, look at it this way, if the OEM specified 5W-30, but you noticed AMSOIL has a 0W-30 available, but not listed as a recommended product, it is because the OEM didn’t list it as a recommended product. It is still an EXCELLENT replacement and one I would recommended if a customer came to me and said cost isn’t an issue!
SEVERE GEAR 75W-140 Synthetic EP Lubricant (SVO)
- Rear Diff – Have not changed it yet, but will be changing it soon
Severe Gear 75W-90 Gear Lube (SVG)
- Front Diff – Have not changed it yet, but will be changing it soon
Synthetic Multi-Vehicle Automatic Transmission Fluid (ATF)
- I will be switching to this soon, but I have some leaks that need to be address first in the trans cooler

- I run it at the 100:1 ratio. Both engines run GREAT and zero smoke.
- I gave a craftsman lawn mower to a friend in Montana before we moved, I used the SAE 5W-30 Signature Series 100% Synthetic Motor Oil (ASL) in it even though that is not a recommended oil for it. When changing the oil or even checking it, that oil still looked clean and new. It looked like as if it was poured from the bottle. I was able to get more “cuts” in and more often than not, mowed our entire lawn on a single tank of gas. Before, I would have to fill it up after cutting about 3/4’s of the lawn.
