Best you can buy.

Run, it in all three vehicles that call for 5 w 20wt.

I have been using this oil in my06 Dodge Ram for years. Makes better oil pressure than other brands.

Great product

I HAVE A BRAND NEW 383 STROKER ENGINE IN MY 2004 SILVERADO. IT WAS RECOMMENDED TO PUT A GOOD OIL IN MY ENGINE AFTER THE BREAK IN OIL WAS CHANGED.READ REVIEWS ON SEVERAL DIFFERENT OILS AND REALLY LIKED WHAT I READ ABOUT AMSOIL. WHEN I FIRST GOT MY ORDER IN THE FIRST THING I NOTICED WAS THE BOTTLES WERE MADE DIFFERENT THEN ANYTHING ELSE I EVER USED. THEY WERE THICKER PLASTIC AND ARE POUR FREINDLY. DIDNT NOT HAVE TO WORRY ABOUT SPILLING OIL ON MY NEW ENGINE.

AMSOIL is THE ONLY oil and lubrication product I use in everything I own. I would put this up against any other synthetic lubricant any day.

Saved my car.. I have no idea why or how, but my car started using about 1 quart of oil every 1500 miles.. I did have about 175,000 miles on the car.. yes, hard miles.. lol.. anyway, I had run Mobil 1 since I bought the car New and changed the oil more often then recommended by owners manual. Thought it wouldn't hurt to try a different oil before I ditched the thing.. well it has 100% quit using oil.. like I'm not kidding.. Just stays right where I fill it to.. like I said, I don't know why or how, and I don't care.. Just very happy I gave amsoil a try. Btw, I would never go 25,000 miles without changing oil.. That's just crazy and asking for trouble.. sorry amsoil.. anyway I'm going to call amsoil one of these days and ask why it quit burning oil and see what they say.. The car is a 2012 civic si that is tuned and slightly modded for power and milage.. i drive 75-84 mph about 95% of the time here in the Chihuahuan dessert in West Texas and so my car engine is working hard most of the time..

I have used Amsiol products in all my vehicles for several years with good results.

Not many choices for 5w-50. This is the only real quality option. Thanks for making the wt.

Switched to amsoil and my engine is quieter, and runs better. I tow a lot with my truck and know with amsoil that the oil is breaking down under heavy load.

I own a pickup and two autos, two utility tractors, four chain saws, three weed eaters and eight small engine machines. I have AMSOIL in each and every one. My Pickup is used to pull a large trailer and for snow plowing for several customers. I also use fuel cleaners, fuel preserve products, oil mix and grease gun tubes. I have experienced oil leaking and oil burning motors stop doing both and a one pull start on the small motors.There is no other oil and other products that compare to AMSOIL.

Amsoil has been my go to for many years. Between quads, dirt bikes, cars, and trucks my rides always perform and run smooth. The oil looks great at every oil change and still has a clarity to it that I've not experienced with Mobil 1 royal purple and so on. Amsoil will always be my only choice.

Been using Amsoil 20 years and have had no problems. Put oil in my Durmax and put the big filter on and did need to change oil only once. Amsoil has been making oil for years, now everyone is trying too.

I use 0-20 Amsoil in my Family crossover. I run it 15,000 mile between changes and the oil still looks clean when I drain it.

I put Amsoil 5w - 50 I'm my 2012 Boss 302. Product works great for regular driving or hittting the track.

The Signature Series oil is the best and most money-worth-it oil that's available from Amsoil...period!

Minimizes actual engine wear while managing fuel economy. Yearly oil changes is great.

I used this product in my SUV, runs smooth get better mileage and start very well in extremely cold weather. I used their product in all my vehicles and small engines.

I use it in all the engines in my house. My cars, lawn mower, pressure washer and generator. I feel my equipment runs better and more efficient.

I've been using AMSOIL motor oil for just over 5 years now and been very satisfied, no complaints...ever!
