Engine oil AMSOIL or ZIC

I got better results from signature 5w30 at 11,200 mi than I did from Motorcraft “full synthetic(lies) at 4300mi. So I change my amsoil at 8-10k and my Pennzoil ultra platinum at 7500.

I like amsoil 5w-30 and do a liquimoly engine flush with every oil change.

On a new car, I change at 750, then again at 3000, and after that I do my regular once per year or 25,000 miles, whichever comes first, as stated on Amsoil Signature. I've been using this oil for decades in cars, trucks, and tractors. It's incredibly good oil.

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

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.

I just purchased their OE formula @ $8.99 a quart...my 2012 Camry, 2ARFE has 212k miles and started burning oil around 150K. I was using Mobil 1 since I ownWe'll, and I noticed I was topping it off every other week...Now, I'm waiting for the oil and see if this will clean up the oil control rings, ring landings, etc. I'll report back.

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.
