Customer Ratings & Reviews

I use 0-20 Amsoil in my Family crossover. I run it 15,000 mile between changes and the oil still looks clean when I drain it.

I put Amsoil 5w - 50 I'm my 2012 Boss 302. Product works great for regular driving or hittting the track.

The Signature Series oil is the best and most money-worth-it oil that's available from Amsoil...period!

Minimizes actual engine wear while managing fuel economy. Yearly oil changes is great.

I used this product in my SUV, runs smooth get better mileage and start very well in extremely cold weather. I used their product in all my vehicles and small engines.

I use it in all the engines in my house. My cars, lawn mower, pressure washer and generator. I feel my equipment runs better and more efficient.

I've been using AMSOIL motor oil for just over 5 years now and been very satisfied, no complaints...ever!

Amsoil makes a huge difference in the performance and longevity of your vehicle. Nothing else goes into my cars, trucks, lawn mowers, chainsaws, etc.

I use this oil in my track car. I have a magnetic plug and nothing has shown up there. The filter is also clean after each use (I check it). Oil pressures are good on track. I plan to use this oil well into the future.

I recently switched from Signature Series 0W-30 to SS 10W-30. I started using 0W-30 several years ago when it was Series 2000 & the top tier Amsoil synthetic. It satisfied most of the vehicles I serviced to simplify my ordering. But recently, since the Signature Series expanded awhile back and my current vehicles all call for 10W-30 per the manufacturers' recommendations as well Amsoil's application guide, I decided to make the change. Living in the Seattle area our temperature range should suit this change just fine. I trust I will get the same level of protection as I have in the past. I examine my used filters and find that my engines stay clean internally. An interesting Amsoil side note: My daughter bought a 2009 Kia Sedona 1.5 years ago (77,000 miles). Her first oil change was done at the dealer with conventional oil. I had to prompt her for her next oil change at 9000 miles! I changed it to Amsoil XLF and last week did the next oil change at 5400 miles (6 months). After the conventional oil change the filter showed some carbon crud in the pleats, but after the first Amsoil cycle the filter showed a significant amount of carbon crud on the filter pleats, many times more than that from the conventional change; the ability for this oil to clean accumulation is impressive. I will do an Amsoil flush at the next oil change in hopes of getting this engine into a better place. I suspect this engine spent its life on conventional oil.

I run this oil in my 2003 Honda S2000 and I love it. Had my head rebuilt and checked the cylinder walls, cams, etc. with 111k miles on the engine with force induction. There were barely any wear at all! I will always run Amsoil.

I use the 5W30 along with the Amsoil oil filter and I run it 15,000 miles before I change the oil. I also use the Amsoil AFT which can keep the transmission temperature up to 60 degrees cooler. Reduce friction and save your equipment

I've been using this since 2003 in my Toyota Solara that has the V6 which is prone to sludge. I now have 470,000 miles on it and still running strong and does not smoke. I change it and the filter about every 10 to 15 thousand miles, sometime longer.

Great oil for direct injection engines

I use Amsoil products in my truck and my wife car. I started using Amsoil products in my race car many years ago and had such good luck with them I have been using them in anything I own with a gasoline engine. My truck has over 200,000 miles on it and it runs like new. We use my wife's car for road trips and I always ride with confidence in Amsoil products. I would definitely recommend Amsoil to family and friends..

In work&personal vehicle.Work car approaching 300,000 miles-Starts easy in old weather-improves gas mileage-don't have to change every 3000 miles as you have to with conventional oil-can't think of anything negative

My engine is really quiet now. That tells me that Amsoil is lubricating the engine in a way that the other oils can't. I changed all the fluids on my 2017 Chevrolet 2500 HD 4x4. Fuel mileage is up and vehicle noise ( engine, transmission, transfer case and differentials ) is down. it truly makes a difference. I've also switched to Amsoil in wife's 2017 Ford Explorer, my son's 2015 Ram 1500 and my 2015 Tahoe Q7i SF boat.
