Best oil available

Best oil on the market in my opinion. I take oil samples and have them analyzed every oil change. Wear metals are down. I change my oil every 5 K miles, No matter what. I don’t trust going over that dew to evidence that sludge will start building up going over that mileage with any manufacturers oil
Bottom Line
Yes, I would recommend this to a friend.

I have a brand new 2025 GMC Sierra AT4 1500. My very 1st oil change at 1k miles break in was this product. Amsoil was highly recommended by other GMC owners. My AT4 will only have 0w-20 from Amsoil in it. Highly satisfied.

Yes, I would recommend this to a friend.

I've been using Amsoil in my Harley for years. Way better performer than HD's Syn-3. Runs cooler too. Also using in my GT350 now. Only been a couple 100 miles so far, but my expectations are high. The price was more that competitive and delivery was fairly quick. Will continue to use Amsoil oils in all my cars and equipment.
