I use it and yes still change my oil at 5,000 my gas motors I run the XL Boosted and diesel I run the Signature Series. Im a 100% believer in the stuff and Im one that don’t like change and did a lot of research and testing in my stuff before fully swapping over. I literally run it in everything I own. Sidexsides tractors trucks boats lawnmower weed eater chainsaws everything.

I run amsoil in mine and I plan on swapping all my fluids to amsoil. I also use their diesel All In One in every tank of diesel to keep the HPFP lubricated.
The video they did with Gale Banks showing their processes really has me convinced!

I’m a big Amsoil fan, same as my father, which is why I started using it. I use signature series in my ‘14 Taurus and my ‘17 F150 with the 5.0, I run 10,000 miles in both and don’t worry a bit. I think 10,000 is safe in my opinion, but thats just my two Pennie’s.

But for the majority (me) putting on 12k miles a year or less, I just think it's pointless. Chasing boutique oils ($), getting lab work done ($) on used oil just to chase a higher mileage number, trusting that 3rd party source, etc...nope. A cheap synthetic oil and regular OCI's work great. 5-6k mile changes work out to twice a year for me. Once in the spring, and once in the fall. Although that should change to once a year soon, because I've been looking for a fun car to buy.

I agree. If I'm on the highway putting 30k+ miles on a year, then I might be able to get onboard. The OP never stated how he used his truck, so we can only guess.

i wouldnt even send oil out for analysis at 12k miles...unless you are just curious how your overall engine health is.
When I talk about using analysis to go to extended OCI's, im not talking 10k, im talking stretching to 20k, 30k, etc... There are some fleet operators going 80k+ miles on a change. They might change filters and top up every 20k or something, but they run really long intervals and use analysis to do so. Also running bypass filter setups can really help stretch the OCI's... My old mans 5.9 cummins with by-pass filter would go 20k+ on a change with analysis. Keeping the soot out of the oil via the filters is a big deal in diesels.
Blackstone is who I use, although Amsoil has a service they recommend, I, for some odd reason, want a real 3rd party, not something the oil manufacturer recommends... not that I think anything nefarious is going on there, just me. And Blackstone is very reputable, no reason not to trust their analysis.

Meet or exceed. I could have used conventional oil in my 7.3 diesel but I used synthetic T6 5W40. Lab tests said I could double my OCI. Yes, money wise it was a push but time of service, it was a win. Less screwing around with 15 quarts of diesel oil and having to dispose of it.

Meet or exceeds the "minimum" standards for extended OCI? New oil far exceeds the standards. I don't like "good enough" oil specs remaining. I drive 2,000 per year, the truck is a pampered barn tenant. 4K on oil is plenty for me, and testing shows that it still meets the newer end of the oil specs. The manufacturer has no interest in your engine lasting forever. That's tough on sales. Using their maintenance schedule is a recipe for a standard engine life. When BMW started claiming that their transmission fluid was a lifetime fill, it was because they offered free maintenance for 4 years, and the wanted to sell you a new car then. The transmissions failed as soon as you would expect.
When our Nascar team tested oil, looking for any advantage we could get, Amsoil was a close second to Mobile 1. It is great stuff, but surprising, the worst oil tested was very, very good. Use whatever color container you want to, and have complete confidence in it.

I think I'm going to try the standard heavy duty and change it at about 7k if all goes well with that I may switch to the signature with a fuel filter system and shoot for a little more just hard to not change it at 5k been doing it for so long it's hard to not lol

Until tested, all you have is a SWAG as to what it mileage you get out of it.

I run their OE line in everything (2 Volvos and the F250) except our Mercedes Metris, I run their Euro that meets the specs. The three that get OE get 5k oci, the Mercedes’ gets once a year (usually around 6k oci).
As a preferred customer cost isn’t terrible. Run their stuff in all power equipment as well, never an issue.
