Great stuff, we’ll thought out.

I've been using Amsoil for several years now. I switched to the Boosted 5W-20 oil in my 2015 Ram for the last few oil changes. I can honestly say I have no complaints. The 5.7 Hemi always has a "tick" when idling, but after switching to the Boosted 5W-20, I don't hear that familiar sound anymore. I will definitely continue using this oil, and switching everything else over to it.

First time using amsoil. So far I’m happy with it. Gonna be changing trans and diffs soon to all amsoil products.

We have converted one car to this product and have a 2nd suv to start in one month.

Once you have used Amsoil you can't go back to a lesser brand. It is the best at maintaining your vehicle's.

I can go more than 6k miles between oil changes and oil is still pretty clean. Great product!

Love the products! I use amsoil in everything that I can find on their list that I have. Not once have I had any trouble. It’s great to only change my oil once a year!

Great quality oil. Switched from Royal Purple which is good but noticed quieter engine operation with the Amsoil.

I purchased my truck in Dec. 2013, with 58K+ miles on the odometer. I have always used AMSOIL 5W20XL synthetic engine oil. This is the required viscosity oil for my 2007 Dodge Ram 1500 Quad Cab with the 5.7L HEMI. I now have 96K+ miles on the odometer. My truck uses about 1/2 quart of oil between oil changes. I also get good fuel mileage with my truck. I highly recommend the AMSOIL 5W20XL synthetic engine oil.

I ordered a complete kit from Amsoil which excluded, a filter and six quarts of oil to complete the oil change. I've done this with two of my vehicles so far. So simple. Will order again

This is great oil NS THE Quart bottles are easy to use. I also noticed that the engine is running smoother. Still looks clean after several miles.

I have has tried all the brands of engine, transmission fluid, additive, and axle oil. AMSOIL products are the best in the market.

So I have always been a royal purple fan boy however I wanted to try this oil out and see all the hype. I have a 2013 Ecoboost for reference. The engine does operate smoother idles. The temp gauge is also one needle with cooler running now. So I’m no scientist however I can tell the oil is making a good difference. I also use the transmission fluid and same results. Been very pleased so far.

Great lubricant I have been using in my vehicles and lawn tractors for 15 or more years.

Oil works as advertised

I have never seen this in the stores I shop I was delight to find that Amsoil handles this weight as it was a gift for someone Love their products

I decided to us this oil in a Civic turbo that my daughter drives and doesn't see regular inspection. So far I have gotten excellent service.

Best oil

I absolutely love Amsoil. Great customer service and speedy shipping. I switched all my vehicles over to Amsoil.

I have used amsoil products for years. I have absolute and total trust in the quality and durability of all the products. Like the old saying goes " pay me now or pay me later ". Use the very best to take care of any engine and the engine will take care of you. Thank you Amsoil.
