2010 Dodge Ram 2500 Mega Cab, 6.7L Cummins, 68RFE 6-Speed Auto, 4x4
  • 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 TriaI. 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!

2-Stroke Weed Eater and chain saw
  • Saber Professional (ATP)
    • I run it at the 100:1 ratio. Both engines run GREAT and zero smoke.
Lawn Mower
  • 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 3/4s of the lawn.

In 2002 I bought a new Dodge Ram 1500 with the 4.7L motor. When I performed the first or second oil change, I noticed sludge at the top of the valve cover and on the oil cap. First thing came to mind was that the head gasket was blown. I contacted the dealer who they said the same thing and to bring it in. After a week in th‍‍‍e shop, the dealer called to pick the truck up. When I got there, they told me that the sludge is just part of the design of the motor and that I didn't have a blown head gasket. Not satisfied with that response, I thought there has got to be something I can do to reduce or eliminate sludge in that motor.

I remember seeing a box of AMSOIL in my Dads garage when I was a kid. Not knowing what AMSOIL was all about, I decided to do some research on them. After about a week of researching the company and their oil, I decided what do I have to lose! I was already using the MobilOne Tri-Synthetic Oil at the time, so the cost was not an issue.

I ordered enough to do an oil change along with their oil filter. After changing the oil, I immediately noticed a difference in how the engine ran and how responsive the throttle was. That engine ran so smooth, I was more than satisfied. Since I bought their extended drain interval oil, I decided to go the full year with that oil. I routinely checked the oil level as well as pulled the oil fill cap off to see if there was any sludge or significant oil loss. To my amaze, there wasn't a hint of sludge and I never had to top it off.

After using this oil in my vehicles for a few years and really enjoyed the benefits using AMSOIL Synthetic Oils and Lubricants, I decided to become an AMSOIL Dealer in 2005.I am passionate about the products AMSOIL delivers, and use it in just about everything. The applications I use their products in are below along with what I currently run or plan on running in them. If you have any questions or concerns, please don't hesitate to contact me. I look forward to working with you and supplying you with the very best oils and lubricants the world as ever known!
