I have the Amsoil 15-40 diesel oil in most of my equipment with no issues,,,I am infact thinking I will be dropping the oil in my 06' six-O this weekend,,,I have been running the Mobil/Delvac 15-40 diesel oil last 4 changes in the six-O,,,but is time for the change,,and winter coming,,thinking the Amsoil will flow better in the cold,,,,Plus I already have the Amsoil,,,Walmart went up to almost $12 a gallon for the Mobil/Delvac 15-40. I will look into the API rating before I put it in the six-O.

I was told that the Mobil 1 lowered the zink and phosphorus levels to increase the life span of the emission systems (CATS). Theres tons of threads on this change in other forums like VTOA 'Viper Truck Club of America'. The Mobil 1 tagged "European formula" 0w-40 is still good and i use it in my two Dodge Viper V-10s.

I use Amsoil in everything I own. From ATV's, Chainsaws, 6.0, Explorer, even my 66' Mustang.
I've noticed a gain of about .5-1 mpg in the 6.0 and that's over a period of about 6 months of testing. Towing or not.
Amsoil clearly states it's rating on the jug and if you're not satisfied w/that - they have a tech line you can call and get assistance. For the money, it's a little more insurance for your investment.
I service a huge farming community and almost all of them have made the switch. If nothing else, the change intervals keep them in the field longer and their equipment has less lubrication failures.

Read the bottles more carefully. The API info you are seeing are just "claims", they are not actual API certifications. Thats classic Amsoil deceptive advertising and many have been fooled by this. The only truly API certified oils that Amsoil offers are listed at the link on the previous page.

I've been using it my Saturn for about 3 years now, after 3 years of Mobil 1. I noticed significantly quieter lifters immediately, as well as mildly improved fuel mileage. When my V-10 comes due for a change, that's what it's getting too.

thats what I thought also, and for you guys doing extended drain intervals on your 6.0's, have you had any oil analysis done on the oil? Many guys have and it show that the oil is pretty much spent after 5,000 miles!! I would be real curious to see a blackstone report on your non API certified amsoil!!

Replaced the timing chain and gears in a 92 454 cheby I owned in a 3500HD truck. At 250,000 miles using amsoil, going 20,000 between changes, changing the filter at 10,000, the engine was surprisingly clean. The mechanic couldn't believe it was that clean with that many miles on it.

amsoil oil & ATF
The Amsoil motor oil I have no problem using knowing that the CEO from Exxon/Mobil retired with a $600,000,000.00 million $ retirement a few years ago. I believe the Amsoil motor oils are better like a lot of you all do. I do wonder about the ATF's and the greases that are suppose to be as good or better than the factory products. I have a 2004 explorer XLT v-6 sohc 5 speed trans. It wants to hesitate a lot going into drive after stopping the vehicle once it's warmed up or hot. It has the amsoil ATF & the greases in it. Synthetic fluids are to help make the trans run cooler, so why the hesitation when shifting from P to D after a 20 mile trip ? I have a 2003 with the amsoil grease and the clutches are clattering in the front transfer case after the vehicle gets pretty warm.it does not have the amsoil ATF. It only does this in turns at slow speeds or slightly turning the steering wheel it does it. Both have the same size engine v-6, 4.0 sohc. If anyone from amsoil comes here, please answer these 2 problems. If anyone has the answer feel free to reply. Thanks

that could be the problem.How many miles are on these cars? How often have you changed the fluids?

Good questions but this can also be a motor transmission mount problem since it only happens when turning.

I have run both Amsoil 15W-40 HDD and 5W-30 Series 3000. I haven't had one problem in over 50,000 miles of running. I have been using extended drain intervals. I change the filter at 10K and the oil and filter at 20K. I did an oil analysis at 20K and it came back that I wasn't anywhere near the end of the oil life. I am hooked so far.
