ONLY Amsoil!

I've taken several engines apart but only engines that have run Amsoil and they only need coolant system work. Conventional oil precipitates out garbage and sludges up engines resulting in CLOGGED oil passages. If your switching from conventional, get the best protection you can get that has tons of positive history. Do your homework/research to understand ALL the costs involved. You will determine Amsoil is the best switch you can make for your vehicles.

A Trusted Product

I have been using Amsoil products in my vehicles and motorized equipment for many years and relay on its quality. As a "gearhead", I know how important using quality motor oils and greases are to machinery. They are my first choice for lubrication fluids.

Great product

I run Amsoil oil and filter in my Yukon Denali 15,000 miles between changes. Just reset the change oil message at 7500. Doing this for years with several GMC Yukon's. At 250,000 plus miles no oil burn at all. Very impressed with not having to go under the car twice as much.

Why is it when I change my oil does my mileage drop by 2mpg. For the first 400 miles 1 1/2 to 2 mpg less then it creeps back up.

Why change?

I started using AMSoil in the mid 80s while in Alaska. Cold extreme make lubrication very critical. At minus 40, most petroleum lubes won't even drip off the dip stick and when started cold you can hear every bearing in the engine as there is little or no lube flowing. No so with my AMSoil.

Not worth it.

I've been running 5W30 Signature Series in my 2002 Tacoma since putting it on the road in 2016 with 116,000 miles on the engine. I have since had Oil Analyzers (Amsoil, Inc.) test three samples from the truck so far, and have yet to have the oil last more than 13K miles before being told it's time for it to be changed. So much for the 25,000 miles/1 year claim...

This stuff is THE BEST!

I have 2 vehicles that have had this oil in them (changed every 15,000mi) since I bought them new. They both have mileage approaching 250,000, and they run like BRAND NEW. My newest vehicle is a 2017 Subie Forester Turbo so it gets Signature 5W-30 every 10,000 miles, and I'm sure it will see 200k and beyond.

Low Milage Yearly User

The recommended Dexos1 oil for my turbocharger car is 5W30. Amsoil is one of the few (only) companies who offer a high quality 0W30 that is Dexos1 certified. Disclaimer, I have no interest in using 'house brand' for my car. Personally I believe aftermarket manufacturers like Amsoil have more incentive to keep my vehicle lasting longer. I have the luxury of not having to drive my car to work, so the annual mileage is well below average. My car also sits for weeks on end and having the lighter oil helps to quickly lubricant my engine when I start it for the first time. I change the oil once a year instead of the kilometres. Choosing the lighter oil increased fuel economy in the summer and allowed easy starting in the winter on those -35°C days (no block heater). In the winter I enjoy skiing in the mountains so I need an oil that stays fluid in extreme cold. On a hot summer day in stop/go traffic I feel confident running the lighter 0W30 oil in my car knowing that my engine is protected. Overall great product and will continue to use 0W30 Signature Series for years to come.

Signature Series 0W-30 AZO Versatility

Using Signature Series 0W-30 AZO keeps my ordering simple. At one time I was using 5W-30, 10W-30, 10W-40, 5W-40 European Amsoil products. There was a time in the past years that the "Look Up A Vehicle" applications commonly listed the AZO as the first listed oil as the top recommendation. After comparing specs I concluded that the vehicles using the 40 weight products didn't really need that viscosity per the owners manual and the other 30 weight oils could all be well serviced by the 0W-30 Signature Series. It is a great product and I use it in all the vehicles I own and the family vehicles I service.

0W-30 SIGNATURE SERIES OIL IS AWESOME!

I highly recommend the AZO 0W-30 Signature Series oil. I have been using it since it came out and the 0w-30 SSO oil before that. This top of the line oil has kept my car running young, now at 449,000 miles.

Gatortail

My order arrived on time and un-damaged. I use Amsoil in my Gatortail engine (Briggs) replacing the oil at 25-35 hours with a total of 550 hours on the engine. The oil holds up very well. When conducting maintenance on the engine the interior working parts of the engine are like new with absolutely no visible signs of sludge build up. I highly recommend the use of Amsoil products. I also use the Amsoil Marine Grease in the lower unit and that product holds up very well as well.

Good stuff

I love Amsoil products. I run this in a 1993 Ford Ranger. With 245k on the motor it still works good and plan on running it for a while. No tapping on start up like other oils. I do alot of short trips with this truck and put alot of hard miles on it, this oil is up to the task.

For me it's the BEST!

I use SS 0W-30 in my daily driver '06 Mustang. Change interval once a year with an Amsoil filter. The oil flows like water but slippery to the touch. When the engine idles all you hear is the muted sound of wet valves, and when I punch it all you hear is pure muscle; no pings, no knocks, just a well oiled machine!
That car sees only Amsoil products and has 86000 miles on it. I have never had to add a single drop of oil to the engine between oil changes, ever. Every week when I pull the dip stick the same 2 punch holes are wet with oil . . . i rest my case, this is good stuff!

I think it's an outstanding oil for cars with a blower

I have a nearly 600hp 03 mustang cobra. Based on the used oil analysis I've done over the past 3 yrs, I've gone almost 6000 miles one interval and the oil didn't shear. I don't know if this makes the 0w-30 SS an outstanding oil vs other off the shelf oils, but I do know that high horsepower applications pls e greater stress on motor oils. So extract from my review, what you wish.

Piece of mind

I travel a lot every week. I usually drive over a thousand miles each week so I don't need to be getting ripped off in quick change places. I don't really keep track of how many miles I go in between changes any more and I've had no engine issue that relate to wear. This product performs as advertised.

Nothing but Amsoil for my Mazda3

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?

Superior 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

2013 Chev Equinox 3.6L

After some research I decided to run 0w30 instead of the recommended 5w30. This was to gain some additional mpg. I chose Ams oil since this 0w30 is rated for GM dexos1.

This is the first time using Amsoil, engine got smoother & getting over 60 miles more per tank of gas. I assume the lower viscosity and the quality of oil are both contributing to better gas mileage. This saves a lot now, so will continue to use this brand.
