this oil has been synthetic for a long time .I was just waiting for 5w-50 to come out.

I bought this car used - it's a 2008 Mazda3 S - from my best friend, so I knew its full history already. He's run Amsoil in it since brand new, and I plan to continue the same. It just rolled over 200,000 miles last week, and mechanically, the car has been in the shop twice in its lifetime - both for air conditioner issues. It doesn't burn or leak oil, and never has. When something is treating you this well, why would you switch to anything else?

I use amsoil in my hellcat it quite at my lifters and seems to add more smooth power

There are a lot of good synthetic engine oils on the market, but none better than Amsoil. I've been using it in all of my vehicles for seven years now, and haven't had any type of engine issues related to wear. No, it's not the least expensive synthetic oil, but I don't "cheap out" when it comes to taking care of my cars. Only the best oil and filters for my machines. It's cheap insurance for my Hellcat. There's really nothing more that needs to be said.

i've been using this oil for many years and i am completely satisfied with it.i actually gained about 2-3 miles more per gallon of gas.i usually change this oil and filter every 8-10,000 miles and when i do it is never black.

love this product

The Best Engine Protection on the Market ! I drive a 2012 Toyota Camry & The Manufacturer recommends 0-20 Weight Oil..... which is supposed to provide engine protection up to 100 Degrees. Well I live in Las Vegas Nevada where Summer Temps can reach 117 Degrees..... The signature Amsoil 0-30 is far more protection

I have been using this oil in my dirt bikes for 40 years now!! I mix it with avation fuel at 83 to 1. they have always ran great!!

This is the only product I trust in my 738hp 2013 Boss 302 Mustang. This is my daily driver and play toy. The signature series has great life in my supercharged application which makes the comparable pricing a bargain!

My '13 Boss 302 takes an odd oil grade....5W-50...and only a few brands offer it...and when they do it's usually formulated for older Muscle cars....so it's loaded with Zinc additives...very detrimental to modern catalytic converters....plugs them up. AMZOIL created their Signature 5W-50 specifically to address Fords running the HO versions of the newer 5.0 V-8s ! The Boss loves it for Breakfast and never Burps. Thanks AMZOIL!! Super Product!

Used in a 2015 Ram 2500, 6.4 Hemi. No tics, Slightly better fuel economy.

I use 5W-30 signature series in my 2005 Mercury Sable 3.5 liter V-6. I get quick starts in the depth of winter (-10 - 15F) and smooth running in mid summer on the interstates. I would never by choice subject my vehicles to a lesser lubricant series that Amsoil fully synthetic motor oil and transmission fluids.

I use 5-30 in my 5.7 hemi. The mileage increased 3mpg, hence free oil.

I use this oil in my 2015 Volvo S60 T-5. The recommended oil is Castrol Professional with an ACEA of A5/B5. I have not been able to purchase this oil even from the dealership (in fact they recommended an off the shelf Castrol oil). Amsoil Signature Series 5w-30 has an ACEA of A5/B5 and I feel it to be a superior oil. Volvo's engines are considered to be long life (million plus miles) I intend to find out with the help of Amsoil

I first started using Amsoil 5W30 on my brand new 1994 Ford Ranger Splash 4.0L on the advice of my uncle who was a dealer at the time. Except for the 4 years I owned a 2004 Saturn Vue 3.5L which used Amsoil Signature Series 5W20, it's all I've used since, and all I'll ever use. It or Amsoil. Here are the vehicles I've used it in, and I advise anyone reading this to use it too. 1978 Ford E150 351W 1994 Ford Ranger Splash 4.0L 1996 Honda Accord 2.2L 1998 Acura 3.5RL 2004 Chevy Trailblazer 4.2L 2003 Saturn Vue 2.2L 2004 Saturn Vue 3.5L (5W20) 2008 Ford Explorer Sport Trac 4.0L 2010 Nissan Altima 2.5 S

I purchased a used 2012 Chevy Volt I did not know what oil had been used may have been dealer oil and filter when I drained out the old oil it came out quickly and very dirty that would explain why the engine may have been on the noisy side. I used the required oil that is recommended and when the engine started there was hardly any noise from the engine and very little vibration. Great oil has been running great since I used Amsoil oil and filter.

awesome as all Amsoil products are! this stuff kicks ! I will be buying more next month. oil held up great still looks good feels good! oil pressure never dropped and still hasn't dropped. 140000 +miles on it worked great all winter long. and I only have to change my oil once a year! how sweet is that,

One of the best Oils on the Market, I have use this product and several others from Amsoil in every motor I own and have never had a failure. From 2 cycle lawn equipment, all my cars, both diesel and gas boat motors everything has been run on Amsoil. Started back when I raced Snowmobiles, and beat all the factory teams.

Learning that most "Conventional" oil lose is caused by consumption (boil off, blow by, clearances ect). I decided to give it a try in my 340K mile Pontiac (45K on a new rebuilt 3.8l HO V6). Not only did the oil lose stop it actually helps cool the engine down better now. Bonny runs smoother. She has always been fast so I do not notice a performance increase. Gas mileage improved. I was getting 17-18 mpg highway. Now I get 22-23 mpg. I get 16 mpg city period. No improvement there. My suspicion in my lead foot has a lot to do with that. At first consumption seemed to be the same. Talking with the local guy he reminded me of the oil cooling lines and oil cooler underneath. That's a full extra quart of conventional right there. Once that boiled off (2 weeks) the oil level stayed constant. I am on my second oil change now. New Amsoil recommended oil filter and new Signature Series 10W-30 Synthetic Motor Oil. Funny thing was that after 15K miles it was still pretty clear. I have 5K on her since this oil change. Still clean on the stick. I became a preferred customer for the savings it offers me and my 9 vehicles. Cutting the oil changes down to 1/4 of what they were makes up for perceived "extra" expenses. the performance and stability of it makes it well worth it. Signature Series 10W-30 Synthetic Motor Oil will be going into the Motor Home next.

I use both Amsoil oil filters and synthetic signature 5W-30 in my 21012 Avalon. Very Happy with both and will continue to use this product. Everyone at Amsoil is always professional and helpful with any questions I have. Great product.
