This is my first round of 0W-20 Signature Series for a 2015 Suburban as well as a 2016 Toyota. Paired with AMSOIL EA Filters, I trust the recommendations of the vendor. I've never had an issue whatsoever. Oil consumption using Signature Series 5W-30 on previous vehicles with over of 180K and 207K miles was ZERO. I loved the cold weather start and 1x/year oil changes (avg 17K miles/year).

I use AMSOIL signature series in my new Ford F-150 because the protection is great, the change intervals can be extended if necessary without lubrication properties breaking down. It conveniently shows up at my door via free shipping as a preferred customer.

I use Signature Series 5W-30 in my '98 Subaru (138,000 miles), and it couldn't be happier.

5W20 is for my 2010 Ford Ranger. I run it hard, and the oil does it's job flawlessly. I use AMSOIL on all 5 of my vehicles. I won't buy anything else but AMSOIL.

Amsoil got my business in 1983 when we were running two stroke outboard engines at very high RPM's in a racing format. After one season putting the engine through these conditions we would rebuild the engine. After the year was up the cylinders still had the hone polishing marks visible to the eye on the cylinders. Every gas or diesel engine I have owned since that day runs on Amsoil and only Amsoil. Why would I try anything else. The extended run time only makes it a better product as far as price. You can get this quality at or near the same price as just oil.

Have been using AMSOIL products 4 more than 20yrs. No bone 2 pick. No vehicle I've owned has used oil, excellent performance. Engines, transmissions, manual & automatics, & live drive axles! No problems ever! I will only use AMSIOL! THANX ABUNCH AMSIOL!

I have been using this amsoil in my Jeep JK 2017 since new, and it seems to be preforming well I also have it in front and rear differential.

I have been using high mileage synthetic oil for the last 5 years. When i got my emission chech the technician was confused, he said , ' the engine is running so clean, its like purifying the air' !

I have used this product for 16 years with excellent results. (All around good oil analysis, much lower cost, time saved.) I recommend this oil whenever possible.

This Amsoil Signature Series engine oil is the best I've used. I call it my liquid Gold. I would highly recommend it.

Great as usual.

I have used this in a few autos as well as a 4 cycle toro, superb engine protection, second to none cold weather starting as well as lower operating temps in the hottest days of summer. Very highly recommended! !

My Ranger has 210,300 miles. All original engine except fuel pump. Runs great. Amsoil in engine and tranny since purchase.

I like to keep my car in tip top shape, so I use amsoil.

A friend of mine has been using this oil for many years and finally talked me into trying it, I have always used synthetic oil but decided to give this one a try, love it..

Amsoil Signature oil is the very best oil on the market and I use it in all of my vehicles.

Here in the California desert we have freezing winter temperatures and summer temperatures of well over 100°. Our cars start easier and run at the proper temperature regardless of the temperature. I use to have warm-up problems or temp gauges that ran closer to the red line in summer. Does it work? Yes and I change my oil religiously one time per year and the oil isn't even black after a year of driving, mostly in town.in our Jeep Wrangler.

This is another product I've been using since it's introduction paired with the EA filters. They make a great combination for protection

I have been running this oil in my Silverado and my Chevy SS and this is by far the best oil you can use. Now I still change my oil based upon the intervals the car tells me but the protection you get can't be beat. My oil analysis have come back excellent!

Use this in my 2016 Chevy SS, and in my wife's Ecoboost Flex. It minimizes oil use and improves mileage. Was using Mobil 1, switched to Amsoil (after free dealer oil changes ran out) and oil stays clean longer and mileage improved about .5 mpg in both cars. This is year over year, not tank to tank... Both cars rarely see the highway nowadays (both wife and I switched to jobs close to home so side streets to and from work it is)...mpg's going from 14 to 14.5 doesn't sound like much, but it is something!
