Just great oil

Good quality. Im satisfied with this oil

I’ve been using Amsoil for several years now. It’s not cheap, but well worth the price.

Amsoil has protected me for years now all my engines never had an issue. All the research I’ve done leads to amsoil being the superior product among the oil masses

Awesome product Affordable Came super fast And most of all got some free stickers

I have read about and watched many lubricant testing videos, and Amsoil always comes out in the top 3, so I believe in their products.

This is the best investment for you engine you can make. Do mid-cycle oil filter changes with a good filter.

Quality product, and great customer service

After viewing numerous reviews comparing motor oils on YouTube. I came to the conclusion that 0W-40 Amsoil Signature was, without a doubt, the best. When you are protecting a twin turbo engine, nothing else is better than Amsoil 0W-40. Nothing.

Very good engine oil

Love all there products

This can be further from the truth. I have an 07 Jeep SRT 8. The previous owner was using another top oil brand. And after my truck would get to optimal running temperature. My oil pressure at idle would drop to 9-10 psi. I changed the oil after 3k miles and heard great reviews on AMSOIL. I used Amsoil Signature series oil. And my oil pressure at running temperature is appro 24-26psi. I will definitely spend the little bit more money. Knowing AMSOIL is absolutely Superior. Customer for life.

I’ve been running AMSOIL in my 2020 Jeep Gladiator Mojave and I’m seriously impressed. The engine runs noticeably smoother and quieter, even after long drives and hard use. I do a mix of highway, city, and off-road driving, and AMSOIL has held up perfectly in all conditions. Throttle response feels sharper, and I’ve had zero issues with performance or oil consumption. It gives me real peace of mind knowing my Gladiator is protected, especially in extreme heat and rugged terrain. Definitely worth the investment—I’ll be sticking with AMSOIL from here on out.

I’ve used this oil for over a decade. It’s kept 2003 Toyota running at peak performance.

At the recommendation of my mechanic I recently switched from 5w-20 to 5w-30 in my 2012 Honda Accord. The first thing I noticed was the engine sounded much quieter both at idle and while driving. I had recently noticed that the 5w-20 was being consumed at around one quart per 3500 miles. While not high consumption, I’m hoping to slow it down. Expect to push this car passed 400k miles.

I’ve been running AMSOIL in my car and changing it every 5k miles. The engine runs smoother and quieter, and the car just feels better overall. Even at 5k, the oil still looks good and does its job. Definitely worth it if you want your engine running great and well protected.

I looked at reviews for manu oils and filters. I decided that Amsoil was the best option. My car was new when I put amsoil in it.

I have been using Signature oil for at least 10 years now and have never had an issue. And the added mileage between changes makes it more affordable than conventional. I have even emailed a couple questions, once about their marine 2 cycle oil and they respond quickly and positively.

Very good oil it smoothed out my engine and made it quiter ,I can feel how much better the engine runs. 2017 2ss camaro v 8 engine.
