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!

AMSOIL has proven to me over the past 20 years that it has improved the performance and mileage of over 8 vehicles and my motorcycle! I will never use another oil!😎👍👍

Have been using for years. The best.

Went to 7500 on my oil change and it was still clean! It was brown but not cloudy and dirty. Shocked.

Been using Amsoil for years on my Q50 and don’t have any issues or problems with my engine👍

I've used Signature 5-W20 oil in my 2015 Jeep Wrangler since it was new and just turned 70K miles. Others I've known have had their engines overhauled at least once while using assorted brands and kinds of oil. My only modification was to install a Baxter oil filter adapter to limit the dry start that's famous for damaging Jeep 3.6 engines.

I have been using the signature series and all my cars for years. Three cars pushing 200,000 miles.

Amsoil is the only automotive motor oil product I use on my vehicles. The extended service interval and high quality product keeps my vehicles' engines running smooth and trouble-free. I have been using Amsoil products for about 20 years. The customer service and value is second to none!

Works much better than OEM.

First time using this product and I'll never go back to anything else ever again

Only oil I use in my wife's Equinox....Have used it for years with zero problems.
