IMO, for the best synthetic oil and filtration run AMSOIL with an AMSOIL 2.00 micron bypass filtration system. When it comes to synthetic oil technology, AMSOIL started it and continues to set the bar for oil technology and performance. -Chuck

I've run AMSOIL for over 16 years in everything I've owned with great results. Because of that long track record, I decided to become a dealer. My 2002 has low miles compared to most. I'm only at 92k now, but I run the AMSOIL Bypass Filtration System with AMSOIL AME 15W40 Heavy Duty Diesel and Marine Synthetic engine oil. I used to run 30k intervals, but now with my low miles I just change oil and filters once a year since I'm not doing over 30k a year anymore. I run AMSOIL everywhere in the driveline as well. All my vehicles, tractors, small engines and equipment (2 and 4 stroke) all run AMSOIL. I've never had an engine failure in all my engines over the years. -Chuck

That looks like fun. I need a wheeler again...

Well ever since ULSD came out I've been running AMSOIL Diesel Concentrate and AMSOIL Interceptor in my 2002. The Diesel Concentrate for detergency, fuel stability, etc. Even though the Diesel Concentrate is one of the better additives for lubricity, as shown in Mopar1973Man's HFFR chart, I add the Interceptor 2 stroke to ensure lubricity. And I'm lucky that even today I can still get LSD #2 diesel in my area, but it is getting harder to find. I find that I don't try to take the hour necessary to explain the lubricity logic to people anymore, I just tell them to go to this site and READ.-Chuck

AMSOIL is the best and it outperforms conventional oils, hands down.-Chuck (one of those pesky AMSOIL Dealers)

It is engineered to burn extremely cleanly at temperatures that are very similar to ULSD. I feel that it is the best 2 stroke product for this application, and I continue to use it. It costs more, and I understand that is an issue. But since it lubricates better than conventional products and is said to burn cleaner, and that I've run it quite a while now with zero issues, I feel the increased cost is worth the protection. AMSOIL makes some amazing products and they have always proved to be worth it. Cheaper than a VP44, that's for sure. Due to the better lubricity, I feel that you can use a pint (half a quart) of Interceptor per tank and get the same benefits as a full quart of a conventional 2 stroke. This is because you can run a 1:100 mix of Interceptor in an engine that is designed for a 1:50 mix of conventional 2 stroke oil and still get better engine protection. Based on that fact from AMSOIL, I feel that running 1 pint is more than sufficient VP44 protection. Since I get 2 tank loads out of 1 quart, the increased cost is negated. -ChuckAMSOIL Direct Jobber

Good info on the traditional paper BHAF. I am running an AMSOIL Nanofiber 4510. It is also a dry filter and costs about the same as a BHAF. I can also clean it with compressed air. I still have my old BHAF that I used to run, and it was a great filter. I'd like to see comparative CFM testing side by side with the Nanofiber and the traditional BHAF. Based on many customer reports, the Nanos have yielded more turbo whistle, lower EGTs, and quicker "seat of the pants" spool up. Of course, the overall point to all this that I think most diesel guys will agree to is that the key to good air filtration on diesels is to run a dry filter. Oiled filters start to cause problems in the real world under the CFM demand stress of these engines.-Chuck
