Buy it NOW. You wont be disappointed! Its the best!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. I have been down the road looking for the best protection and have finally found it in AMSOIL products. Thank you AMSOIL. Item Reviewed: XL Series Motor Oils

Best oils for any and all applications Period!I have been a fan of Amsoil for several years after switching to if after using Mobil 1. At oil change time, Mobil 1 would pour out like water. The first time I used Amsoil and did a routine oil change the difference was startling. The oil had maintained the same consistency, minus color, as when I first added it to the engine. Upon cleaning out the oil drain pan, the used Amsoil oil was so slick, it actually appeared to not have broken down at all. Don't buy any other product, buy Amsoil and you too will use nothing else.

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.

The Right Lubricant for the JobThe 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. This is a better approach than "one oil fits all" approach. Item Reviewed: XL Series Motor Oils

Great ProductHave always used either Amsoil or Mobil 1. Both are great oils and and every other oil change at 7500 miles in my Toyota Tundra, Lexus, Mazda and Honda CRV. I send the old oil off to Blackstone for analysis. The analysis of Amsoil and Mobil 1 both always show excellent wear and Blackstone recommends that I could go much longer between changes. Thus I usually buy Mobil 1 because I can get it at Costco, don't have to pay shipping and this makes it much cheaper. Item Reviewed: XL Series Motor Oils

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! Item Reviewed: XL Series Motor Oils

Impressed !I had heard about Amsoil and reviewed their data and wondered how much was real and how much is just advertising. Then I bought a new truck and thought to myself that I'm really going to have to take care of this thing because I probably wouldn't be able to buy another one in this lifetime due to cost and old age. If the data I had seen was accurate than Amsoil was the direction I needed to go for protection. I used the factory oil for 4900 miles then made the switch to Amsoil. So far I'm very pleased. Most notably with the fuel economy. I've gained 1.5 to 2.0 MPG in highway driving. That to me is impressive. I'm sold. Item Reviewed: XL Series Motor Oils

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. Item Reviewed: XL Series Motor Oils

Best Synthetic for High MileageMy car has over 385,000 miles, and convinced this motor oil a major reason its still going strong.
