OUTSTANDING OIL, I HAVE BEEN USING IT FOR YEARS FOR MY 3 CARS,I DON'T USE ANYTHING ELSE.

I have been using Amsoil since 2001 with no problems and I have been able to extend my drain intervals backed up with oil analysis. I am currently using it on my 2021 F-250 and a 2018 Nissan Armada. On the Nissan Armada I I’m running the signature series for at least 10,000 miles with room to spare all this backed up by doing oil analysis and making sure that you have a good TBN. I’m on my first fill on the F-250 and will be taking a sample at 10,000mi to make sure that I’m still good.

I've been using this oil on both my 2015 Jeep SRT and my 2008 Jeep SRT8 for the last 3-4 years. They both run so smoothly and the longevity of this oil is unmatched. No one comes close in quality to AMSOIL!

I spent years running different oils and comparing quality and performance. Amsoil in my experience performs the best, from below freezing temperatures to high desert temperatures, superior lubrication and wear protection, and all temperature performance to any other oil I’ve tried.

Happy with the product. Engine runs quieter and performs better.

received oil promptly, no issues with shipping. Exact amount of oil needed and proceeded to change without problems, new vehicle for me and was not sure what oil former owners used. I use Amsoil in all my vehicles: 2 motorcycles, 2 jeeps, a truck and a Lexus. No engine issues.

Great products and oil filter.

Works good

This is the absolute best oil available for my 2007 Mercedes-Benz C230 Sport. I drive about 18000 miles per year, and I change my oil 1 time per year. This oil is well worth the money!

Been using Amsoil for many years great customer service and fast delivery

I have used this oil since day one on two brand new Toyotas, 2020 Highlander,2021 Tundra. Excellent cold starts

Started using this oil and I can honestly say it runs cleaner and the oil pressure stays consistent throughout the entire time between oil changes. My oil level is also remaining the same with little too no loss at all.

Awesome in my 6.2L Silverado

Perfect oil for my 08 LS 460

I’ve used this oil in my ‘04 mustang cobra for years .I also use the same stuff in my ‘02 Ford F-250 and my wife’s ‘18 Ford Rapter.I just like knowing I have the best oil money can buy,hands down.The ‘02 F-250 has over 120,000 miles on it and runs great. I’ll keep using this oil from now on.

I can wait longer between oil changes which saves me time!

One of the most important aspects of this product which switched me over from another synthetic oil competitor is the volatility rating. I had experienced oil loss previously, but I know with the regular oil changes that I do and verifying the PCV system was not obstructed, I landed on the problem of volatility. With some lesser quality synthetics it can result in oil evaporation. My vehicle has a number of miles on it, but the amount of oil loss, and the duration of time it happens within, was considerably, and significantly different when I switched to Amsoil.

After 2 oil changes motor just purs, operation is quieter and acceleration is smooth powerful and not as noisy on RPM revs. Invest in your cars/trucks engine life longevity and get your case of 5W30 Signature today!!

I'm happy with my purchase. It's the ONLY oil I use. I just wish I could get free shipping. Being that I'm a member. it should be part of the perk
