Amsoil is the only oil I use in my challenger rt. As is the oil filter.as soon as I change my oil I can see the difference in performance right away. Great oil for your engine.

Installed signature 5w30 at 1st oil change. No, consumption during the factory recommended change intervals (5000 miles). Pickup has 53K on it with no oil related issues. Unless I’m pulling my 9000# enclosed trailer my fuel economy range from 17-22 mpg. This pickup is driven in temperatures from-20-90+ degrees and 10% ethanol regular. I’m a happy F150 driver

I have used AMS Oil signature series in all of my vehicles for decades. I have used it in sports cars, sedans, trucks, and suv vehicles with amazing results. Currently used in an Acura MDX with almost 200,000 miles and still runs like new.

Been using Amsoil for 2 years now and all of their products have out performed everything else I’ve used their products consistently deliver time and time again and that’s why I’m a preferred customer and will not run anything else in my vehicles

Signature series speak for itself but this oil is excellent for sub zero temperatures in winter season for state of New Jersey. The car starts up fast with minimal metallic noises in the first 5 seconds which are crucial for lubrication in cold temperatures. I will continue to use this weight and sub in 5W for spring / summer applications. Lastly, the vehicle has about 218k and is quiet as a sowing machine.

Great product and service

i have been a customer for over 30 years always use Amsoil products their Max heavy duty deiseal 5w30 their 75/90 server gear and their heavy duty GL2 grease and their 5w20 all work great all cars and trucks have over 350'000 miles on them and do not use any oil and run great

The confidence this oil gives over others is great

The best product!!!

This is the best motor oil out dear period.....

Always buy Amsoil, actually felt like it made the engine run smoother on our new car.

AMSOIL Signature series engine oil is first rate. I have used this product in all three of my vehicles for years. I have had to add additional oil to any of the vehicles, months after changing the oil. Great product that is reasonably priced.

I have been using Amsoil Signature Series for 5-6 years now. Here in Wyoming with severe winters the flow of the Oil, my engine turns over like its 20C (70F) out when it is -25C (-10F). Even though the Oil is more expensive than the Full Synthetics the longer oil change intervals make up for the price. Before 2 oil changes for what I do with one Amsoil. Recently replaced the Timing Belts on my car and have to remove the valve cover as part. The upper engine has zero sludge and just a light golden color inside. High mileage on my Accord. Engine clean and well protected.

I have been using Amsoil for many years I used it in all of my Harley motorcycles and both my car and truck

I've been running Amsoil for years and recently changed the spark plugs in one of my 3.6l Pentastar engines. Engine currently has almost 190,000 miles and I haven't had a single mechanical issue. I also changed the intake manifold gaskets while doing the service and the top end of the engine stills looks amazing.

Amsoil products are the best! Hands down. All my rigs will allways run Amsoil products.

Having switched to Amsoil from Castrol I can tell you that I immediately noticed a smoother operating engine. Not a thought of using anything but Amsoil from now on.

Made my 2022 Nissan titan way quieter runs smoother

Works great on my 2022 Ltd Silverado

First, let's address the elephant in the room. This stuff is EXPENSIVE! Now that we have that out of the way, let's go with a more important issue. Your engine is also expensive! The tests verify that Amsoil is the best. So now the question presents itself, with such a sizeable investment (your vehicle), why wouldn't you want the best product to protect that investment? I've been using Amsoil for years, and I'll continue to do so because I don't have tons of disposable income, and I want to protect my sizeable investment. Thanks Amsoil!
