Been using their oil in all my diesels.

This engine in it's beginning back in the 90's was spec'd for 10w-30. In my opinion, the debatably worst decision Chrysler ever made will quiet down and run buttery smooth. It's not going to turn the torque-less wonder into a powerhouse, and your mpg might drop a fraction of a percent but come on, you're driving a vehicle with the aerodynamics of a refrigerator box. At the very least, give your mini-van engine the oil it needs.

I only changed my oil every six months. I never put more than 8000 miles engine is absolutely clean not a problem all good.

Just cheap insurance policy, knowing that you have the best oil out there in your car especially new cars with turbo i’ll spend the extra couple of bucks to fill my car oil reservoir with Amsoil signature series

Amsoil makes the best oil for your vehicle hands down. My 4runners love this oil!

Awesome oil for all the vehicles. Runs like new.

I use it because it never let me down yet ! simply saying I use it because it works

Ever since switching all my vehicles to AMSOIL I have noticed a difference in performance. Great product definitely recommend if you want your vehicles to last.

I've run Signature Series specifically in my turbo DI daily driver because of the protection it offers against LSPI that plagues these engines. It's worth every penny knowing I'm running an oil I can count on.

I love and trust the quality of the product for all of my engines. If Amsoil sells it for my vehicle, I'm using it, and i know it is protected. I just wish it wasn't as expensive, but it is what it is. Great stuff. I love it overall

Use Amsoil products on both high my mileage gas and diesel vehicles.

Ordered another 12 quarts of America’s Best Oil for changes on my Raptor and Bronco. I won’t run anything else, and being a preferred customer bringing the price down, makes it even better!!! No complaints from me whatsoever.

I just switched from Amsoil Euro to Amsoil Signature Series for a 2023 VW Taos. I ran a used oil analysis at that change and the wear metals are 3.7 ppm/1000m. The SUS viscosity is spot on. I have been changing the oil at about 5k miles. I completely trust Amsoil to protect the engine for a long time. That is not an easy job with a small turbo 4-cylinder, DI engine. I am also going to extend my change interval to probably 6500 miles this time and do another used oil analysis. I am going to standardize Amsoil Signature Series on all my vehicles. Not to mention their customer service is great and I get the products quickly. Thank you Amsoil!

Hands down best there is!

I am really happy with the quality of the signature oil. They are supposed to send me a multi tool for free but never got it. I called customer service and they didn’t resolved the problem.

Has been working out great for the last 125k miles in my acura. Combined with oil tests change interval of 20k has shown no degradation in protection.

I have a 2017 hyundai Santa fe sport with the 2.4 gdi motor. I just had the valve cover gasket changed by my mechanic buddy. With 175000 miles on it he couldn't believe how clean the top end was. No sludge and the camshafts looked like new with no visible wear or discoloration. The car runs like new! He was thoroughly impressed as I was too! Now he is thinking about becoming an Amsoil dealer! I will always use Amsoil products and signature series oil! Keep up the good work!

I have run this type of oil and all my vehicles for a very long time one of my vehicles actually hit a half million miles without being rebuilt and was very little issues with sensors and all this type of things it actually helped clean up a car that had bad oil put in it cheap stuff and I had to replace the sensors for once the sensors were replaced I never had to do it again the cleaning agents that this all has is unbelievable and it makes sure car run better and will keep the inside of the motor clean and in a lot of cases it'll actually stop cars from using oil but don't count on that the first time sometimes it takes a couple oil changes before you get all of the old junk out but stay with it it's well worth the money

The best oil there is IMO. Been using it for years in everything with an engine and have never had any engine failures or problems.

I have been using amazoil for many years. There is nothing else I will put into my vehicles. I have even had it tested by our local cat. Dealer, after being in for a long period in a period of time, it tested better any other oil by far?
