Or recommendation from a very reliable source, I went to the 550 synthetic in my Chevy Camaro 3.6 engine going to add a Tracy Lewis Catch scan soon to really extend the whole life and keep things clean

Amsoil Sig Series is the best - Always have glowing results from Blackstone Oil Testing.Robbie

My oil of choice over even Mobile1

The last rebuild of my 1986 Toyota 4Runner I switched to Amsoil 10W-30, and it's now over 407K miles and the 2200RE runs smooth and perfect. Burns very little oil, no smoke at all. I can't wait to see how long it holds up, I would never consider using anything but Amsoil.

Great product and excellent customer service. Highly recommend.

I was 10yrs old when I saw a neighbor with his work van wrapped in AMS Oil logo. That was 45yrs ago. Growing up I began to see AMS Oil in automotive shops and Drag racing events. I purchased my first round of AMS Oil and filter to run in my 2025 Ram 1500 3.0l SO. I look forward to running AMS Oil in all my vehicles and motorcycles. Better late than never!

Been using Amsoil for over 12 years and always arrived at my doorstep quickly. Blackstone lab has always gave great results for this oil no matter what car I run this in .

Always trusted Signature Series however had to bump up my viscosity based on an oil sample submitted recently.

Top notch product. Never had a negative experience with any Amsoil product. More then 1 vehicles, I switched to Amsoil auto transmission fluid have shown significant improvement (including smoother shifts and less/stopped slipping)

Amsoil is the best engine oil money can buy. Improves mileage and malkes engines last for well over 100,000 miles.

Easy to read side makings, nice top to poure products

Highly recommended full synthetic Amsoil.

This is the only oil I have ever used in my Blackwing and it is amazing.

This is excellent oil for my Toyota RAV4 hybrid! I bought the car new and want to start it out on Amsoil and Amsoil filter. So it's only had 500 miles on oil other than Amsoil.

Keeps the motor internals cleaner than any oil I’ve ever used

Best oil on market

I used amsoil products for many years. Cars, motorcycles , small engines. I don’t have any problems with oil consumption, timing chain or anything else . I know it’s more expensive than other oils but I believe it’s worth it.

Seems to be good

Ordering the kit simplifies the process of getting the correct oil and filter for your vehicle.
