AMSOIL Devoted to Protection™: 75% More Protection

AMSOIL ran the American Society for Testing and Materials D6891 Engine Test – The gold standard of motor oil protection. The test conducted by an independent third party lab is designed to stress the oil’s ability to protect against wear and simulates 100 hours of stop and go driving. At the end of the test, the camshaft is evaluated in 84 places to measure overall wear. Find out how our Signature Series Synthetic Motor Oil performed. To learn more, visit

Where does it rate against all others ? I have no problem paying for a supier product but is it ?

It may not appear obvious but the comparison is against other brands that only meet the minimum test standards.  That should nearly qualify as "all others".  Despite the transparency Amsoil offers in their test data (best I've found in 25+yrs), there will always be specific comparisons "left out" due to the myriad of test specs. and oil brands/types.   There are about 10-12 key oil test specs, when combined offers a good picture of how oil works and protects.   An easy self test is to be pro-active with the equipment you own and know well.  Utilize the Oil Analysis program by testing pre and post oil samples.  Ultimately this is what counts, not a specific test regimen.  Amsoil deserves credit for upping the ante with specific "show case" testing like the one shown, however.  After 17yrs of using Amsoil (switched from another well known American made brand) could not reasonably expect an oil to be any better. -- Another key point is consistency across the product line; I don't need to worry if their gear oil is "good as" the engine oil for example.  And specs are available, including White Paper test studies.  Some brands seem to make Halo products, or excell in a specific test sequence but are otherwise lackluster -- or worse -- while Amsoil takes, apparently, great care in ensuring each product is best-in-class.  Honestly, my customers, including the cars we repair/fix/modify, take no issue with the costs and fully rely on me to make the best decision for them.  Amsoil has fully proven itself to me years before selling it.  The engine, transmission, axle repairs prevented or prolonged by using this oil are numerous in our shop. -- They are located in Superior, Wisconsin, and I believe and trust the name is fitting - Superior.   Thanks and best of luck.

I'll give you one good example, I broke the serpentine belt on a 1995 ford f-150 when I was about 16 miles out in the country with nothing around. I drove to Albany ,Ga. (12)miles to the auto parts store ,opened the hood and put the belt on. Oh, Not to mention the truck already had over 150000 mi.on it.Needless to say I don't use ANYTHING else.

Couldn't agree with Frank Mottola more(see below. Amsoil is actually cheaper to use in the long run. Heck, in the short run! Especially with a quality filter (Amsoil or Wix for example). If you have a car that's burning oil, you have an engine problem not an oil problem. That's when oil analysis pays off and can help you identify why you're burning oil. I know. That's exactly what I did with my 2002 Nissan Altima. The analysis revealed problems with bad seals. Easy fix and still driving that Altima using Amsoil XL 5W-30. I hate car payments! And every product I ever used from Amsoil is indeed superior!

Sam Lippert, become a Preferred Customer and buy Amsoil at dealer or wholesale cost. It's the best quality oil, lubrication products, fuel additives, etc. Definitely will save you money.

If the oil is this good, I should only have to change oil about three times a year or so. That means the higher cost of this oil  doesn't matter,,,,,,,,,,,

Don't believe the HYPE, check your oil after 3,000 miles. I used the XL (10k) and was almost out of oil @ 4k.

The loss of your oil has nothing to do with oil it self, your car or truck might have high mileage and be burning oil. Ams oil is great oil that is all I use and I am in Northeast! Every pice of equipment I own has Ams in it mower- snow blower- tiller it's great oil!

Sam lippert,

I have been using Amsoil for over 8 years and yes the price is a little costly up front,  but if you account for the amount of time and money you take away from your family and the actual cost of the oil change say about 25.00 per oil change times 5 changes per year =$125.00 +the cost of time. Or would you rather pay 70-75.00 once a year and keep the time with your family. 

Give me a call if you have any other questions 717-571-3845

Well, started using the Signature Series 5W30 about four years ago and so far so good, no problems yet from 88K to 136K miles. Suppose I should mention I use the dual filter remoter filtering device.

As an Amsoil dealer I would never solicit business in this manner.  Surely Amsoil would not approve and will identify the conflict of interest.

Glad to join the high-mileage club! I've been using the Signature Series 5W-20 in my 1996 Grand Marquis (good ol' 4.6L V8 - with 231,000 miles) and I'm getting 24-25 mpgs in town, 28-29 mpgs on the highway. Unheard of in a V8! I did not know about AMSOIL until a friend and I started looking for better oils for our cars after getting tired of dirty oil every 3000 miles - which at that time in my Grand Marquis, was at about 200,000 miles. My issue then was loss of oil - was using Mobil 1 Extended (which ended up being the oil filter adapter gasket - common problem and easy to fix). The QUAKER STATE my dad had been using had become like acid on the gasket, and the poor heat transfer between the oil and the cheap FRAM filter deteriorated the rubber around the metal housing. After the repair, two changes with AMSOIL at 5000 mile intervals, I've been using the same oil now for 20,000 miles and the engine oil is not even dark on the dipstick. It's a beautiful gold color, not to mention I have full power at the throttle when I need it and the car cruises like a champ. 300,000...Here I come!

Even though this video is purely about oil, I'd like to add that I've since also changed the transmission fluid with AMSOIL Mutli-Vehicle ATF (fixed torque converter shudder instantly with full change), the differential with Severe Duty Gear Oil and SlipLock(no more whining), the power steering with the Multi-Vehicle ATF (again, no more whining), and the coolant with the AMSOIL Heavy Duty coolant (after several flushes and a thermostat change). As any student, I'm struggling to 'make-it' financially, but as a preferred customer with AMSOIL, I've been able to plan my small investment in my transportation over time - that way I am issue free in the future. Honestly, people buying or because their current ride isn't running 'just right' is probably due to poor maintenance with the cheapest oils and other fluids. If you take the time to understand that engine failures and other component failures are due to the fluids they use failing, you'll consider getting the best for your car. You can't get the best at the local autoparts store or even the dealer. Only AMSOIL.

I started using Amsoil in 1975.  In 1978 I purchased a brand new 4 cylinder Datsun pickup.  I promptly way overloaded it (read truck body resting on the bumpers) by installing a full size cab over camper.

I had read about how the "big boys - ie simi drivers" did not change oil until oil analysis indicated doing so.

I purchased some oil analysis kits from a automotive parts house and started using them.  About every 5k miles I would send in a sample.  I did change the Amsoil filter as recommended.  

Bottom line is that by 77,000 miles I felt SO guilty that I finally did my first oil change.  I sent in an oil sample and the results came back, "We do not recommend changing oil at this time."

The body of the truck was falling apart due to the winter salt used on the roads in Kansas City.  In 1985 my wife finally made me get rid of it.  It then had over 200k miles on it.  By then I was adding a qt. of oil about every 7500 miles.

I have used Amsoil in every auto, motorcycle, boat, and truck I have owned since 1975.  If it hold oil or needs grease it gets something made my Amsoil.  

The bottom line is that it is far cheaper than the "change your oil every 3k mile routine" plus you have the ultimate protection for your autos, etc.

I first changed to Amsoil when my 03 Camry's oil change schedule was changed by Toyota from 3500 to 5000 miles. the next oil change showed level down to 3 qt (2.0 liter 4 cyl) Changed to OE and Amsoil filter (higher density filter than  toyota's best. traded the Camry for Prius V which recommneds 0w20 pennzsoil synthetic.  I still use oe 5w20 in my 97 Caravan 3.3 with 152000. not much mileage so with 10,000 mile filter, change it once a year. (I don't drive it more than 7500 mi. in a year. Love Amsoil as it is a true synthetic and not a product distilled from natural gas with additives  like Pennzoil. (Pennzoil good oil, no problems, but they stretch the synthetic designation) Amsoil pure syntheitc is not a petroleum product.

I use to run the stuff you can buy at Walmart and Amazon (Mobil 1 and Motorcraft) and a slew of others. I bought a 2007 Mustang GT about two and a half years ago and the motor was in pretty rough shape. The guy before me changed the oil maybe three of four times in its 85,000 miles and thats after the Manuel said to do it every 5000 miles. I dropped the pan and pulled the valve covers and began the long process of de-sludging the pigsty that was present at the time. I ran Motorcraft 5w-20 and a motor craft filter in the Ford and and Mobil 1 in an old chevrolet. The chevrolet would burn a quart every 750 miles and the Ford would clatter and make all sorts of weird sounds on the ford oil. I switched over to Amsoil signature series at about 100,000 miles on both cars and the difference was amazing. The old 4.6L V8 in the GT quieted down and ran cooler and the chevrolet consumed next to nothing in oil and i saw a defeinate improvement in cold starts aswell a slight increase in fuel economy. I dont think ill ever go to another oil as long as there is This Liquid Gold we know as amsoil.

I've used Amsoil for over 15 years an I'm a master Harley Mechanic working on all types of Motorcycle, and small engines too.  The power foam saved a customer from an engine tear down cause of a sticky valve an the technician was able to get the motorcycle  running well enough to spray some power foam into the engine to free up the sticky valve an the problem was solved ..   Big Money Saved !!

Just switched to Amsoil on my Massey Ferguson tractor (2016) and better filter than stock.  (Mitsubishi D-engine, 3 cyl).  Not sure if it's going to make difference but I'll be changing oil every 50+ hrs (spring and fall, at least).. Amsoil has all the certification recommended by the owner's manual.  I just have to find a kit to test oil before and after to see if anything is going on.  I'll be switching to Amsoil for hydraulic and gear oil too... price a little more than competitors but a lot lower than the stuff the dealer sells.  Time (and tests.. and performance) will tell.

Do you make oil for diesel
over 5 years agoJuly 11, 2017
I have been using Amsoil in all of my machines since 1999.  '98 T100 has 165K and runs like new.  2002 Odyssey was still running great when we sold it at 170K.  Newer Odyssey and Accord also on Amsoil.  I absolutely trust the protection it gives the engines and appreciate changing the oil only once a year.  Also keeping the T100 automatic working great with Amsoil ATF and Sever Gear lube in the rear end.  I never worry about the heat in the summer, because that's where Amsoil products really shine.  Also have a 27 HP John Deere diesel with Amsoil in it.  The first time I changed hydraulic fluid, I used JD fluid.  Within a short time, I started hearing what I thought were gears grinding.  Finally figured out it was the wet brake disc when I changed to Amsoil hydraulic fluid, and the noise went away.  Also use Amsoil in my riding mower, standby generator and two-cycle engines.  Never been disappointed.

I purchased a new 1985 Plymouth Colt with a 1.5 liter 4 cyl engine and a 4 speed manual transmission. I coworker told me about Amsoil and I decided to use it in this vehicle once the motor was broken in. The EPA rated gas mileage was 37 city 44 highway and I was matching the highway mileage and obtaining slightly under the city EPA rating. I put the recommended marine grade Amsoil 75W90 in the trans at 6,000 miles and Amsoil 10W40 in the engine at 11,000 miles after the charted gas mileage had flattened out. I then averaged 44 mpg city and 50 mpg highway until the car was sold at 105,000 miles when the very expensive failed carb caused the emissions testing to fail. After the Amsoil was used the car felt a little more powerful, the shifting was much smoother, especially noticeable in the midwest winters, and the gas mileage, wow! The car never burned a drop of oil with the oil filter being changed at 12,000 miles and the oil at 24,000 miles. I had the oil analyzed once at 18,000 miles at Faber Labs and the results were that it was performing as new oil in lubrication and there was no dirt buildup. Amsoil is amazing stuff!
