Customer Ratings & Reviews

Great product increase I fuel economy and engine runs quite and cooler no regrets switching to amsoil.

I have been using Amsoil products for over twenty five years in all my vehicles and have never had a problem related to poor lubrication.I have never purchased a new car in my life and routinely run up over 200,000 miles on whatever I'm driving.I think that say's it all. Frank

I switched all my cars and bike 2 yrs ago very happy with the performance

I use this weight in my 2009 Hyundai Genesis, and it has over 107,000 miles on it.

I use this oil on my work trucks (2) 2016 Dodge Ram V8. Uses different weight but XL kind.

I've been using AmsOil for my Subaru Impreza WRX since 2005 and when our family truck, the 2008 Toyota Sequoia finally used up the extended maintenance service contract in 2013, I started performing the oil changes myself with AmsOil XL products. Since my WRX has been on this synthetic oil for many years, I figured having both vehicles on the same oil would be the best thing I could do for them to keep them performing at their best. It's been the best feeling to be able to treat the cars with these proven and high quality products, specially Oil and Oil Filters on both my cars. I don't feel bad if I push the cars a bit or if I miss the change interval by a few thousand miles, although that is rare, but I have a sense of trust that it will continue to protect the engine even if I slip a bit. glad to be using these products.

I like to drive my vehicles 200k to 300k miles before replacing. Amsoil has always gone the distance for me.

I use the oil in my Subaru and my gas mileage has improved. Once a year oil changes are nice.

Use this in my old Chevy 454 powered motorhome. This motor really works hard and gets Hot. Oil pressure stays up on hottest days and no leaks or oil burning. It's the best protection for my motor that I can find.

I' started using Amsoil 8 years ago because of issues I had with Mobil 1 figured I'd try Amsoil and was impressed by the mileage increase and price, plus the longer service intervals.

I've done more research on motor oil than I care to admit to. I only use AMSOIL products in my four cars due to the testing results the company continually achieves. I need longer OCI's too, so, it's a win win.

I use this XL5W-30 in both my pickup trucks. Being a mechanic by trade I wrench on other people's stuff all day long and I don't have time to be worried about my own. I use amsoil because it's the best protection for my engine, I don't have to worry about changing only every 5000, I just drive it and when the time comes I change it. The stuff to use if you're lazy lol.

I have been using this oil in the last 2 cars I have own and I am very satisfied with it.

Amsoil is the only oil I use in my cars and it is far superior to the other brands.

I use the motor oil in my small engines and my vehicles engines and transmissions, I started when my dad used the 100:1 2 cycle oil in chainsaws back in the late 70's

I tried Amsoil when I noticed high consumption rates in my wifes car. With Amsoil there was less oil consumption and the oil doesn't break down as noticably. I just ordered Amsoil XL5W30 for my truck and spare car. I even have it i my lawn mowers.

Excellent oil that meets or exceeds OEM specs. Keeps engine well protected under daily use and the occasional track days, when engine is use and abuse. On engines that I have inspected internally looked in good shape and tear and wear are minimal

I've been using this in my Nissan Murano for over 40,000 miles. I can't beat it for the price and fuel mileage gains.

It is a very good oil keep my engine clean and quite no sludge anywhere

I use this in my 1996 G.M.C. K 1500, and my 2004 Toyota Highlander Limited all wheel drive. NEVER had a product problem. I generally change the Oil Filter (with an Amsoil filter) at 5k, top off, do a complete oil change at 10k, I use nothing but Amsoil products in my vehicles. Between the two, there are over 300k on the vehicles! I also use this oil in my lawnmower.. I know I'm not supposed to, but,, it works! I just change it every new mowing season.
