Engine oil Castrol or AMSOIL

Amsoil 100%, I tested it quite a few, and I’m noticed the least amount of decoration and power loss with it

5w30 Amsoil, ignore the tick it's normal.

I replaced the plugs, oil/filter and air filter with oem parts when I got it. I\u2019ve been changing the oil at 5k intervals with the recommended Castrol 0w-20.

Also, I have upgraded to Amsoil Synthetic Engine Oil which further helps for maintaining DPF health as it reduces ash that can accumulate and plug the filter.

I run Castrol (bought at Walmart), like my father and his father did before me...

I use it in my non deleted CJAA (dumb) but I haven't had any issues (yet) and it doesn't burn oil.

My brand new one acted the same. I did an oil change at 1000 miles and went with Amsoil Hybrid 0w16. Since the oil change I really don\u2019t feel the vibration, much smoother.

AmsOil 10w30 for turbo engines... haven't had any issues yet. Still consumes it though.

Amsoil's biggest 'benefit' is a longer service life. Their additive pack doesn't break down as quickly, so you can run it longer between oil changes. However, if you're paying twice as much and running it twice as long, it's a wash and you're not gaining anything. When I was selling Amsoil, I had a modified 4 banger and a high mileage 24v that had both been running Rotella for the entire time that I owned them before switching to T6 when it was introduced. I pulled UOA samples every 1k miles, then switched to Amsoil Signature after 5k and did the same thing except I pushed the Cummins to 10k. Zero improvement in fuel dilution, wear markers, or carbon build-up. After seeing there was no real-world benefit, I stopped selling it. I won't market a product I don't believe in, let alone one that I see as an outright scam.
