Product Application Specs

XLO 10W-40 Synthetic Motor Oil

• API SP, SN Plus, SN
• ACEA A3/B3, A3/B4

Product Description
AMSOIL Extended-Life 100% Synthetic Motor Oil is overbuilt for road warriors so you can confidently drive up to 20,000 miles (32,000 km) or one year², whichever comes first, between oil changes. A proprietary combination of advanced synthetic base oils and a boosted additive package promotes cleanliness and prolonged engine life. AMSOIL Extended-Life protection delivers peace of mind and convenience.

AMSOIL, the leader in automotive synthetic lubrication, produced the world’s first API-qualified synthetic motor oil in 1972. Trust the extensive experience of AMSOIL, the First in Synthetics®, to do the best job protecting your engine.

Resists Oil Breakdown
Extended-Life Synthetic Motor Oil maintains its fluidity (viscosity) under extreme conditions. Some oils break down and significantly increase in viscosity after extended periods of high-temperature operation. These changes can cause excessive oil consumption, engine deposits, accelerated wear and difficult cold-starts. AMSOIL Extended-Life Synthetic Motor Oil resists oil breakdown, ensuring protection in extreme temperatures.

Protects Pistons from Low-Speed Pre-Ignition (LSPI)
AMSOIL Extended-Life Synthetic Motor Oil features unique chemistry to protect your engine against the harmful effects of low-speed pre-ignition (LSPI). LSPI is the spontaneous ignition of the fuel/air mixture prior to spark-triggered ignition. Most new engines feature gasoline direct-injection (GDI), often coupled with a turbocharger. These technologies heighten the possibility of LSPI events, which can destroy pistons and connecting rods. AMSOIL Extended-Life Synthetic Motor Oil is formulated to guard your engine from LSPI.

Keeps Engines Clean
Extended-Life Synthetic Motor Oil is fortified with a boosted additive package that neutralizes acids and resists sludge, corrosion and carbon deposits. The extra protection built into Extended-Life Motor Oil provides peace of mind knowing your vehicle is getting premium protection and the convenience of extended drains.

COMPATIBILITY & MIXING AMSOIL
AMSOIL Extended-Life Synthetic Motor Oil is compatible with conventional and other synthetic motor oils. Mixing other oils with AMSOIL motor oils, however, will shorten the oil’s life expectancy and reduce its performance benefits. AMSOIL does not support extended drain intervals where oils have been mixed.

Aftermarket oil additives are not recommended for use with AMSOIL Extended-Life Synthetic Motor Oil.

TECHNICAL SERVICES
For immediate answers to your technical questions call (715) 399-TECH (8324) between 8 a.m. and 5 p.m. Central time or email tech@amsoil.com.

SERVICE LIFE
Normal Service - Up to 20,000 miles (32,000 km) or one year, whichever comes first, in personal vehicles not operating under severe service.
Severe Service - Up to 12,000 miles (20,000 km) or one year, whichever comes first. Severe service conditions include commercial or fleet vehicles; excessive idling; or frequent towing, hauling, plowing or driving in dusty conditions.

• Modified engines (non-stock), racing vehicles and vehicles using alternative fuels (E85, CNG, propane, etc.) are excluded from extended drain interval recommendations.
• Change at the vehicle manufacturer’s recommended drain interval outside U.S. and Canada.
• AMSOIL Oil Filters are designed for extended drain intervals. Do not exceed 12,000 miles (20,000 km) or one year with other brand filters unless longer intervals are recommended by the vehicle manufacturer. Always change filter when changing oil.
• Check oil regularly to maintain proper fill levels. AMSOIL Oil Filters stop smaller particles, flow more oil and last longer than regular filters. For best performance, use AMSOIL Oil Filters.

HEALTH & SAFETY
This product is not expected to cause health concerns when used for the intended application and according to the recommendations in the Material Safety Data Sheet (MSDS).

Fantastic

Use this oil in our motor home, three cars, it's just awesome! We live in Anchorage, Alaska, and the cold winter starts are great-we don't hear any knocking when we first start the vehicles in the morning, and yes we do use the motor home in the winter to go snowmobiling-and the temperature at night can go low as -30 degrees (it did happen), the motor home started with no noise coming from the engine-quiet. As to other conventional oils you would hear cold oil knocking until until the oil warms up, NOT AMSOIL!!! And the mileage-we saw an increase in miles to gallon ratio. I'm will always stick to AMSOIL!!!

Look my friends, if you have searched for the best oil on the internet for countless hours as I have, AMSOIL is truly the best you can get so stop searching and just get it. I have tried many, many other brands and nothing I have ever used even comes close to AMSOIL. I use AMSOIL products in all of my small engines, lawnmowers, weed eater, pressure washer, generator, as well as my personally owned vehicles. This stuff is the real deal and doesn't evaporate, and does just what is it is supposed to do, that is, protect your equipment/vehicles. Don't waste your time and money looking elsewhere, just give AMSOIL a try and you wont use anything else.

My truck has the cam phaser knocking for the last 60-70K miles. I decided to try AMSOIL so I ordered the signature series oil and filter. My truck started using a lot more oil after that. Not sure why. This time I switched to the xl series oil. Now it's not using as much oil. I'm not sure if it's a coincidence or what but I'll stick with the xl oil for now.

I have rebuilt hundreds of gasoline and diesel engines. I know very well how important top quality engine oil is but I didn't think you could hear a difference in engine sound until I put 0w20 xl amsoil in my 2011 honda crv with 110,000 miles on it. I didn't expect to feel or hear any difference as I never did at any other oil change in my life but the first time I brought it up to speed on the highway it sounded quieter than usual so I done a few rapid accelerations and was convinced it was definitely quieter so I changed it in my 2012 crv with the same results. This amazes me that oil can make this difference as after thousands of oil changes in my life I had never experienced this before.

A long time user.

All my cars (well, except for the ones with mileage above 400,000 km) and motorcycles get synthetic oils in them. When I can get Amsoil, that is my oil of choice. Amsoil has been my desired oil for years. Is it better than any other brand of synthetic oil? I don't know from experience, however synthetic oils help my vehicles run cooler, and I believe that synthetic lubricants provide a more consistent layer of lubrication under all conditions of use.

It is an excellent product and it is really cheaper to use than conventional motor oils because of the extended change times. I have run Amsoil as long as 24,000 between changes with no problems.

The Amsoil XL series has protected my vehicles for many years. When the formula was changed to protect against Low Speed Pre Ignition (LSPI) as well as an extended drain interval, I knew it continued to be the right lubricant for the job. Recently I purchased a pickup truck that could be vulnerable to LSPI so this formula change was very timely. I appreciate that Amsoil offers many choices for lubricant applications.

Amsoil saved me from expensive engine repairs!

Ok, I am an Amsoil customer for life... Seriously! In February when it was still wicked cold here in Maine, I was having some engine starting and idling problems with my SUV when the overnight temperatures were 15F and colder. The engine would default to a safe "limp home" mode, and I was facing some expensive engine overhaul costs. My mechanic was very sure the symptoms had to do with dirty cam phasers. He suggested using Amsoil Engine and Transmission Flush to clean the engine (including the cam phasers) and switch to Amsoil Signature Series Synthetic Oil. I followed his advice and the results have been AMAZING! After the treatment I have had zero starting problems. And even better, the rattling sound that I thought was the water pump turned out to be the timing chain... no more noise! The Amsoil Engine Flush and motor oil solved both problems and they have given my 135K mile engine new life. I plan to treat all of my vehicles with these Amsoil products, and that includes the transmissions as well. If that wasn't reason enough to use Amsoil products, when I made my first purchase I decided to register as an Amsoil Preferred Customer. I saved much, much more than the registration fee over the cost of Amsoil products at the local auto parts store on that first purchase alone. Engine problem solved and low prices equal CUSTOMER FOR LIFE!! Thanks Amsoil!

Great stuff

I have 3cars (one older corvette), 1 truck, 1 boat, and one Harley Davidson. I use Amsoil in all of them. My last truck I traded in had over 300,000 miles on it. Dealer commented "wow , this truck still runs great". all my vehicles run quiet with very little mechanical problems due to engine wear. I wouldn't think of using any other oil in my vehicles.

Best oil by far!

I use this oil on my 17 camaro ss and by far the best oil I've used! I put it in all of my 5 cars now and I wouldn't use any other brand from now on.

Extend your oil change intervals!

Love this product! My 200,000 plus mile Grand Cherokee is still going strong and getting 19 mpg. If your concerned about the added cost, don't be, with the extended change intervals you will save money in the long run! I will be changing my new wrangler to Amsoil as soon as it need fluid changes.

So far, so good

Using this for the first time. I've used amsoil for many years; usually the signature series but I'm trying the XL because I don't put a lot of miles on any specific vehicle I own. It seems to be a good alternative with a little break on the price.

I will always use AMSOIL in my vehicles.

AMSOIL makes oil changes well worth it. I know they upped their change intervals, but I still change my oil every 10k miles. When I do the oil change, it almost seems like I should be following their new interval suggestion. The oil after the amount of use is darker, but it's still very fluid and not thick like other oils I've used before AMSOIL. I use their filters along with the XL oil and it is the perfect combination. I thank AMSOIL for some of the best products.

I have used this product for several years. I now have 240000 miles on my 1996 Ford ranger Ranger. I change oil before my annual Archery elk hunt, and add a bottle of PI. Easy as eating Pie and Ice cream.

Best Synthetic for High Mileage

My car has over 385,000 miles, and convinced this motor oil a major reason its still going strong. This oil has a higher viscosity than other synthetics I've tried, which allows me to use a good synthetic for thermal protection, yet prevents minor leaks typical for high mileage cars.

Good oil, but could be better

I was told by the Northstar project manager at GM to use this weight oil in my 2002 Cadillac DTS. After 250000 miles I've had no problems and she still runs like new.
My only complaint is this weigh of oil isn't offered in your Signature series. Wonder why?

Amsoil has been the only choice in lubricants since 1985, what else needs saying? Multiple BMW motorcycles, my wife's 2000 F150 with many miles, a couple of Suzuki Sidekicks, both high mileage with routine maintenance only. Enough to convince even those with little automotive knowledge.

I will always use AMS oil

I am 71 years old in my second childhood. I have used every kind of oil in my life time. I personally will never use any other oil in my special car other than AMS. I bought a 2013 SI Honda Civic and I put a supercharger, different exhaust and had it dyno tuned and much more. Results over 300 HP to the wheel. I fell safe using this oil up to 6000 miles but I change at 30% not 15%. If you use this oil in your car you will never change to any other. I guarantee that.
