Sioux Falls has a Secrete Low Cost 10W-30 Synthetic that Exceeds the Competition!

Advanced Engine Protection and Performance available in the lower tier

Best in class, best in grade. A Cheap 10W-30 in price but not cheap in quality. That’s the OE (Original Equipment) API Certified 100% synthetic designed with the best additive package in the price range of all your lube shops and auto parts store brands. We don’t sell a lot of this one because no one expects AMSOIL to have a lower tier oil. But it’s perfect if you want to use AMSOIL in that older 2nd car or if you do oil changes as a service.

How to prove it’s good? You will notice how nice the engine runs. It’s really that simple. But AMSOIL Does not have stockholders so they can up the additive package quality a few notches w/o having to deliver a profit margin. Also our raw material purchases are HUGE with our industrial division which has allowed AMSOIL to keep this product impressively LOW!

 

Provides Advanced Wear Protection

OE 10W-30 Synthetic Motor OilOE Synthetic Motor Oil provides excellent wear control and protects critical engine parts like pistons and cams. This added protection is particularly important in the extreme environments produced by today’s smaller displacement engines that often run lower viscosity oil. Camshaft wear can result in poor valve timing, greatly reducing engine efficiency and leading to expensive repairs. The Peugeot TU3M Wear Test (CEC L-38-A-94), which must be passed to meet the GM* dexos1® Gen 2 specification, determines a motor oil’s ability to limit wear. For 100 hours the four-cylinder test engine is subjected to extreme, wear-inducing conditions. AMSOIL OE Motor Oil provided 47 percent more wear protection1 than required by the GM dexos1 Gen 2 specification.

Protects Pistons from Low-Speed Pre-Ignition

OE Synthetic Motor Oil features unique chemistry proven to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct injection (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. A properly formulated motor oil is critical for protecting your engine against LSPI.

Original equipment manufacturers (OEMs) like GM have addressed the issue by designing tests to determine a motor oil’s ability to prevent LSPI. OE Synthetic Motor Oil achieved 100 percent protection against LSPI2 in the engine test required by the GM dexos1 Gen 2 specification– zero occurrences were recorded throughout five consecutive tests.

2022 Subaru Forester

By  AARON,  a  Verified Buyer  from  Little Rock  on  April 14, 2025
I changed out the oil of my wives car with this and I could tell an immediate difference in performance when driving. The engine feels smoother when accelerating even with a CVT. I’ll buy this again!

 

 

Awesome

By  ANTHONY,  a  Verified Buyer  on  April 08, 2025
With product added to my vehicle I’m getting better than manufacturers stated mileage per gallon.

One of the best oil out there!

By  GEORGE,  a  Verified Buyer  from  Bowmanville, ON  on  April 06, 2025
I run my 3 cars on Amsoil oil for a while now and I had absolutely no problem. While all oils might be ok, if you change them on time, some will protect your engine better and prolong it’s life. Amsoil it’s one of them.

By  ERIC,  a  Verified Buyer  on  March 29, 2025
I’ve been in auto business for over 20 years I’ve heard of AMSOIL but never tried it until now. I have a Ford Explorer ST less than 30,000 miles. I put this oil in my vehicle and run smoother. I thought i was going crazy but it is and also my fuel miles also improved very happy with this oil and going to be putting it in all my vehicles. And also vehicle at my dealership!
