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.

great stuff

In my motocycle

The to go motor oil for all 0W-20, 0W-30, 5W-20, 5W-30, 10W-30 applications except europeans.

I only trust Amsoil in all of my vehicles.

very good

By far the best motor oil I've used!

We Transport trailers with our pickup and run only Amsoil in it. Love the extended oil changes, especially since we run so many miles. Because of the ability to run more miles on it, it actually is cheaper to run Amsoil. Wouldn't run anything else!

Use it in honda crv.Great oil. Long life.

A couple of years ago I had my 1998 Chevrolet Silverado in the shop for an intake gasket repair. About mid-day I received a call from the repair shop asking me what kind of oil I ran in the engine. They were amazed as they told me they had never seen an engine so clean inside. I told them I had been running Amsoil in the engine for the past 1.5 years. I had heard of Amsoil for years and talked to a diesel mechanic a few years before and he ran Amsoil in everything he had. I figured if a diesel mechanic ran it in his vehicles, motorcycles, and lawn equipment it was good stuff. I have not been disappointed, I immediately noticed easier cold starts and better gas mileage in my vehicles. With the miles my familiy's vehicles travel, a once a year oil change with the extended life best synthetic oil on the market is a convenient and cost effective solution for ensuring my vehicles engines are protected with great lubrication. And the added bonus of creating less waste for our environment is big for me as well. Convenient online shopping and dependable delivery put my vehicle's lifeblood in my hands within days of ordering it. Love the product and will be using it for years to come. Dale
