Good

Excellent product that works well with my wife's 2010 Hyundai Elantra GLS. The engine doesn't miss a beat and is ultra quiet with the high lubrication properties of this oil.

I've using this in my '06 Dodge Stratus since new. I've just rolled over 70,000 and put the bore scope down through the oil fill to see how the valve train looked. It was remarkable. It didn't even looked like it had been run. Everything looks new. No varnish at all. These 2.7 V-6 Dodge engines don't have the best reputation either. Known for sludge. Running good as new with 10W30 Signature Series.

Only just started using this one and due to the great success I have had with using Amsoil products, I am expecting extended years with the new vehicles and oils. I am using this in two different high reving turbo charged engines so a bit different for me. But I rely highly on the product Amsoil delivers.

I have been using this oil on a 2013 Honda Accord for greater than 220 thousand miles and believe it's a big reason the engine is working awesome. I average one to two oil changes a year and the car still gets 530 to 570 miles on a tank depending how I drive. I use Amsoil in all my vehicles and highly recommend it.

Since I have started using your oils my Vehicles seem to be doing better with oil consumption gas milage I use your products first They work!

I switched to Amsoil 8 years ago and will not use any other products. Far superior than all others. Very fast shipping as well.

Made my 2015 Jeep Wrangler run better than Mobile One, Amsoil is a great product

This is the only lubricant I fully trust for my vehicles

Simply the best synthetic oil on the market. Ordered via Amsoils vehicle configurator and received the oil and filter together and ready to use. Happy customer and happy pickup!

Great product great service

Been using Amsoil for 4 years not disappointed

The oil and filter change to Amsoil reminded me of when I once had the power steering fluid changed, but this was my car's motor; wow.

I started using AMSOIL synthetic oil products some years back and have not had any engine issues at all since then. Test after test proves that their product is the best on the market and I am a firm believer that it is superior to all other brands.

Lots of people believe that most of the additives and selling points in motor oil is just snake oil. And I would say there is definitely some truth to that, I don't know what is real or not but I do know I can feel quite a significant difference when I switched to amsoil. My 370z runs super clean and very smooth. It was smooth before but I didn't realize how smooth it could be until I switched. Your car will thank you

Love the extended drain intervals. Only oil I trust to do it with

I have been using this product in my 2017 Subaru outback from the day we bought it. Oil is still honey gold when drained highly recommend this product.

I've used Amsoil in almost everything I own. Never had any issues and strongly suggest using it in everything from engine oil to chainsaw bars

Arrived quickly and as ordered. Only issue was free bonus was not included or sent, even though requested with the order. Maybe next time?

I’ve been buying Amsoil for decades. I’ve never been disappointed in the quality. I have a new F-150, I’ll be dumping the break-in oil at 500 miles and using signature series 5W30 (not 5W20). Anyway I strongly believe in Amsoil.
