I was introduced to the signature series by a friend who works on motorcycles for a living. He told me a story of this guy who called him and said he didn't have any oil pressure in his bike. My friend said bring the bike over and he would look at it. The guy showed up three hours later, and when my friend asked him what took so long. The guy said he had to drive it there, from North Carolina! We live in South Carolina. My friend tore down the bike expecting major damage, but not even a score on the walls of the bore. I won't use anything else, and because my wife's car has a twin scroll turbo in it, i make it a mandatory when doing maintenance!

I use this product in my 1989 Toyota pickup truck. This truck has 360,000 miles on it and is going strong. I also use Amsoil in all of my other vehicles and would not consider anything else.

best oil hands down, make sure to check your oil often. When running this if your low you wont know it unless you check.

Use in my 99 ford Explorer

I use 5w30 in my car that has just shy of 200,000 miles I recently switched from 0w20 too 5w30 because of the miles I drive the car everyday pretty hard 75 miles each way too work I use amsoil since day one in every application possible and I have zero signs of wear on anything from the brake components too injectors

Great product to buy and also dependable

Been running Signature 5w30 in the last 3 brand new vehicles I have purchased. Change them over at 1st oil change. Does well in the hottest summer days and the coldest winter days. Use with the amsoil ea filter when available for my application and run 15k miles for change intervals.

Amazing motor oil! I use it in all my American vehicles. We drove the RV to DisneyWorld in FL. I forgot to pack the oil change. Ordered oil online, Amsoil shipped it and it arrived the next day in FL. Easy oil change!

Been using Amsoil since 2001 nothing else can compare.

Runs great in my Tacoma and the oil is still running strong with 6,500 miles on the oil. Power and mpg still runs great.

I run a fleet of vehicles and we use Amsoil in all of our vehicles. We get great life from all of them.

I have been using Amsoil for a couple of years now. It started with my 2012 Chevy Traverse. Chevy required that I use a oil that was partially synthetic. I started using this because my dealership didn't work on Saturdays and it was hard to get in for an oil change. Also I soon realized that I couldn't trust the quick change oil shops either. I have a shop that will use my oil and charge me a reasonable fee for changing oil that I can trust. I like that I can go for a year on the oil and it helps keep my cost down. I would like to add my brother uses this oil also. He has a 2004 GMC Yukon XL with over 250,000 miles on it now on the original motor. When he started using it he had around 130,000 miles on the motor and it was using about a quart of oil every 2000 miles. When he started using Amsoil it kept using oil until he had around 6,000 miles on the first oil change and it suddenly quit using oil. We are both convinced that Amsoil saved that motor. Him and I are using Amsoil in all of our engines as well other Amsoil products and are extremely happy with Amsoil and will keep using it

I started using Amsoil Engine Oil in a higher mileage (130k) V6 and have noticed less lifter noise on startup. The oil seems to have good viscosity after 3k miles which should indicate longer oil change intervals. I also changed all fluids (diffs, trans, transfer case) over to Amsoil and have been very pleased with how the drive train feels. Of course new fluid always makes it better but it seems to coast and accelerate better than ever so I think the fluids have improved the vehicle performance slightly. At this time I haven't noticed any drastic MPG improvement but I do think there's just a little more power.

Love how long between oil change

I 've used this oil for a long time never wanted to try anything else like oil with color in it I just wanted a truly good product thats why I stayed with Amsoil hasn't let me down and I recommend it to everyone

Love the different colored bottles. ONE oil change a year, at this quality, I'll take it. It's cheaper thank you think

I use AMSOIL 10-30 Signature in 3 vehicles,,and have an AMSOIL user for over 25 years. I use 10-30 Signature in all 3 vehicles,and AMSOIL Diesel oil in my daughters Class A motor home

Used amsoil for 20+ years. SS series is great for long drain intervals. All of my engines have many miles on them thanks to protection this oil gives.

my 99 acura is running great after oil change

Personal oil changes. I like the fact you don't have to do oil changes for a year or 25,000 miles
