This oil definitely is everything they claim. I started using Amsoil in my Motorcycle ( Harley Davidson). In air cooled bikes oil is everything. And now use in everything I own. Never a concern with upper valve train quiet operation and increased free rpm. In my 5.7 liter hemi very noticable the difference in valve train quietness just like the Harley and Indian motors. Again you can't go wrong.

Only the best for my daily driver and my racecar. Great oil, great support. Great shipping time.

Had great results with the transmission fluid so since buying a new motor for my 2015 nissan frontier 4.0 engine decided to start fresh with this oil and will continue to use . Thanks amsoil.

I started using AMZOIL about 2 years ago, and I use 3 different types depending on which vehicle. I am a carrier technician and I am in my 50th year. I'm a believer in proper service and use this on all my vehicles. I started that after watching Gail Banks videos. Keep up the good work. Danny

My wife and I have owned an auto repair shop for 38 yrs. We have always been about quality. Now that we are retired, we want to give our vehicles the best we can. We are high mileage drivers. We use Amsoil products only. Of course nothing is an absolute guarantee. But knowing our vehicles are getting the best we can give is a real piece of mind. Thank you Amsoil for giving us your very best. Very very satisfied customer.

The Amsoil Signature Series oil is absolutely perfect. I change it at 7,000 miles. My Honda CRV runs very smooth. And gets excellent mileage.

Used in smaller cid engines and it works. Seems with running moderately to heavy and that real lubrication was happening. Oil change confirmed it.

It's watery oil that Toyota recommends.

What do you say about an engine oil, I’m not a petroleum chemist? I only use Amsoil engine oil in all my mobile equipment. After putting hundreds of thousands of miles on my cars and seeing the condition of the valve train, or cylinders when I have an oil pan dropped to change a rear main seal, for over 30 years it’s no contest. I don’t care what viscosity is required, if it’s Signature Series I’m confident in the protection. I don’t believe there’s any better.

I have been using Amsoil on my Ford Edge since the first oil change & I won't use any other oil. I love the pour point for this oil, the OEM oil had difficulty starting at -12C after sitting in a detached garage overnight. With the Amsoil it never had any problems starting even without being plugged in. Even with temperatures dropping to -38 outside.

Très bonne huile

I started using this in my Colorado with over 200K. It burns less than a quart after 6K miles. It doesn't seem to lose viscosity like I did with Pennzoil or Mobile 1.

I have been using Amsoil in all my vehicles for over 20 years with no engine failures, excellent fuel economy, and low wear numbers in oil tests. Plus the 25000 mile or 12 month change interval makes using Amsoil an easy decision.

I have a 2019 Honda CRV I could smell gas in the oil when I changed the oil. I have not smelled any gas in the oil since I switched to Signature Series oil 80,000 miles ago.

The only oil I use in my gas vehicles.

Out performs all other products.

I’m gonna start this review with a little introduction on how my story with Amsoil started. In 2006 I purchased a brand new Yamaha Raptor 700R, which is a 4 wheeler for those of you that don’t know. So in the first year, maybe two years of ownership I tried all the different oils out there that are available on the market and I just wasn’t happy with any of them. I tried mobile 1 I tried royal purple I tried all of them from every oil brand out there and when I finally discovered AMSOIL and put it in my raptor, which actually when I switched to Amsoil, I never switched back to anything else I stuck with it. the difference in performance on my raptor was phenomenal and not only did it have more power and not only was it faster but something strange occurred, I could tell that it was running much cooler. I could keep my hand on the engine without it, burning me, even under the roughest of riding even at the sand. I know that this 0W 16 that I’m writing a review about is not the same oil that I ran in my raptor, but it indeed is the same oil and I also noticed the same thing happened with my Toyota Camry that I’m running this on. I’m running amsoil 0w16 in my 2018 Toyota Camry and I ran in the summertime, I’m on my fourth oil change now with with amsoil and I’ll never switch back from this moment on I will never run another vehicle with conventional any of the other brands out there. None of them even come close not even close not mobile one not none of them. Amsoil is the best oil on earth. And I’ll tell you that right now I don’t need no oil analysis or scientific study to tell me what my raptor was telling me Amsoil was straight up lubricating that much better. The engine ran cooler because there was less friction straight up so what does that tell you no scientific study or oil analysis needed… I don’t care what anybody says. There’s no oil on earth better than AMSOIL

I run Amsoil Oils in all my vehicles. Engines / Transmissions / Transfer Cases / Differentials in all my Cars, Trucks, Motorcycles, gas & diesel… I use the Signature Series 5W-30 in the one vehicle that calls for a 5w-30 oil.

Best oil I have ever used. Truck run extremely smooth.

It's the best oil you can buy!
