Engine oil AMSOIL or OEM BMW

I do 3k with Amsoil SS as well. Blackstone analyses of TBN show I could easily do 5,000k.

I do in my BMW. Oil is cheap compared to a re and re on a diesel no longer sold in country.

5000 miles with a quality full synthetic will serve you well for the life of your vehicle.

Maintenance, that’s what I’m focusing on rn so far ive done oil and coolant, went with amsoil and Nissan blue

I used AMSOIL signature, and do yearly oil changes.

I used Amsoil when I did mine. The squeeze bags they have make changing the fluid a lot easier and it's good oil.

Biggest thing I see here is the 400 ppm increase in zinc for amsoil, which will keep the cam happy.

5K with AMSOIL Signature Series. Any family daily gets the same mileage and quality oil. Yes it\u2019ll cost me a few hundred more over the lifetime of the vehicle, but is worth the peace of mind that if it\u2019s not the best oil you can buy, it\u2019s damn close.

I have amsoil in mine. I went 7500 once. Im sure anyone can go 10k with amsoil but it will be dark oil when u change it out lol

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.
