On my next Oil change I will be Replacing with this Oil, I intend to do one or two oil changes a year only as we don’t drive that much. If they had a filter that goes with this oil I woild buy it.

Best oil in the world. 2007 Prius: 200,000 miles and only added 1/4 quart in 19,000 miles. No motor wear, no sludge, no mechanic bills.

Was first introduced to AMSOIL by uncle a few years back. Have a 05 F150 XLT super-crew cab with that troublesome 54L 3 valve triton engine. Was starting to have to add about a quart of a oil every couple of weeks, granted the engine had 265,732 miles at the time. Uncle told me to use AMSOIL synthetic, and I should see a difference. I'll be damned if it didn't make a difference. After the initial oil change to the AMSOIL, it was probably a few when I checked my oil level, it was still where I had topped it off at. Don't know what additives they use, but definitely the engine ran smoother, no more oil loss between changes. Well, I just replaced that engine, the original engine in the truck, was at 275,586 miles, it was tired. Definitely starting the new engine out on the AMSOIL 5W-20 synthetic, if it made that much improvement to an old tired engine, I can just imagine the results I'll have with a brand new engine and AMSOIL right from start, the truck will definitely be outlasting me!!

Have been using Amsoil in my pickups and side by side with great success. 250,000 miles on last truck, still running strong when I traded it.

Promptly taken care of

Received my oil filters 3 weeks ago, still waiting for the oil, where is my oil?

I upgraded to this lubricant from Mobile 1. I noticed an improvement in my gas mileage and the performance of my Ford F-150 Supercrew with the 5.4 engine and a hair over 95,000 miles. I would definitely recommend AMSOIL.

This to date, is “the best” automotive full synthetic oil, I’ve ever used!👍🤓 I’ve tried Pennzoil, Syntec Gold, Mobil1, Valvoline Full synthetic, Royal Purple, Redline (also great, just quite a bit, more expensive)

Awesome product, I would recommend people to buy Amsoil products. The only feedback I have is the packaging. I recently bought a gallon of oil. The seal was slightly peeled which caused oil to leak out. Also the oil filters are not warped in plastic like before. I love Amsoil, I just hope they improve their packaging.

Great oil for cars that supercharged

I run this in my wife's edge with 2.0l turbo, seems to idle smoother on this then it did on Valvoline.

Since i have used AMSOIL in my motorcycle with no problems, I am putting 2 gallons of their 5W-20 in my truck ahead of a long trip with trailer in tow. I will spend the extra cash when i need the best.

Best Oil you Can find!! Engine runs smoother, Get a great fuel efficiency, Protects your pistons!! Cant say enough!! Take care of your investments!! Worth every dollar!!

until i found this oil , i did believe that all oil were the same

Excellent lubrication

Use this oil and there filters when in stock love the product recomend to everyone

I never go as long as the manufacturer says is allowed between oil changes. My current car manual states 10,000 miles or one year. After 2000 mi. I changed to Amsoil Signature. One of the few 0W-30 out there. I then drove to 5000 and the annual oil change was due. The warranty with the car required one free oil change. The dealer put in the manufacturers oil. In the next 5000 miles I had to add oil. In the next change I switched back to Amsoil Signature. In about 6000 miles is used less than 1/2 quart of oil. I think the difference is in the quality of the oil. The manufacturer uses some European stuff. It meets the manufacturers requirements but I don't think it is nearly as good as Amsoil

As far as I can determine, AMSOIL is THE ONLY true synthetic motor oil on the market. I am a 30+ year member of the SAE .

I have been using this oil for 3 years and it has been the best, longest lasting oil I have ever used. 40k Miles later my truck runs smoother than it did back before using it. Way to go Amsoil!

great item, does an amazing job, definitely highly recommended
