Customer Ratings & Reviews

have been using this oil for 2 years on my '15 Ram Cummins. overall happy with oil . I sample my oils to extend intervals. I used Rotella T-6 prior and had better sample results. No concerning results, Rotella was just better.

Always a great experience. Best oil around. Ram 2500 Cummings

What can I say? I’ve been using amsoil for 16 years. Great stuff.

I’ve been using AMSOIL synthetic lubricants for my pressure washer for over a year now, and I’m genuinely impressed with the performance and quality. The engine runs smoother, quieter, and feels more responsive, especially during long drives. I’ve noticed improved fuel efficiency and extended oil change intervals, which has saved me time and money. Their products are top-notch, and the customer service is exceptional—always prompt and knowledgeable. Whether it’s for my car or pressure washer, AMSOIL has become my go-to choice for reliable, high-performance lubrication. Highly recommend to anyone looking to keep their engine in peak condition!

This is the first time with Amsoil in my truck. From initial start up and driving i noticed a difference. First the engine is not as noisy and also I don't see as much smoke from tailpipe. Great Product. Thanks to my representative. Always has the right answer for your products!

So far I haven’t had any issues with using this oil, it’s the only oil I use. I have a 2000 Ford Excursion with a 7.3 liter diesel engine! Has almost 300000 miles

Have used Amsoil products for years and they provide the superior reasults for my diesel engine that I require...

I've been using AMSOIL in everything I own as I have been a preferred customer for many years. My BX 2670 runs cooler and quieter on AMSOIL. I love this stuff.

J’ai confiance au produit que j’ai acheté jusqu’à maintenant. Je trouve juste que la graisse manque un petit quelque chose pour la durée de vie.

Great product at a great price. Fast ship

Got my order in and noticed the bottom of the box was wet with oil. I opened it to find one of the quarts had leaked a little. I called to let them know. Not only did they immediately send me another quart, the person I talked to had me check every bottle and the filter to make sure it hadn't gotten oil on it. Things happen it shipping to every company but the way they handled my issue was spectacular. Great customer service!

This oil seems to hold up very well, the viscosity is excellent. This is the only oil I've ever used that seems to hold up better than the rest I've tried in my class 8 truck.

Great oil for the Cummins

Really like the product and will keep using from now on and will use other products in the future

This is the besr stuff you can use. Can't beat the price hello
