I switched from the 0w-20 on a Jeep 3.6 and Subaru 2.4l turbo last fall, both motors sound quieter on start-up and when the oil is at max temp. I have seen no reduced MPG after making the change. On the Subaru turbo motor, the oil temps under higher boost/loads are 3-4C cooler and on the 3.6l it has a couple more PSI of oil pressure during low speed high load off road conditions.

I've been using Amsoil since 2001. It's the best oil!

My daily was being used with other synthetic oil brands and was always giving us a sowing sound but that was with 5w20 and now we are border line close to 200k miles and after switching to 5W30 we noticed a big difference especially in the mornings!

Have been running this oil in two Pentastar 3.6 liter engines. Now over 150k miles on both. No problems. Both run quiet and smooth.

Just bought a new 2026 RAM w/3.0 liter Twin turbo engine. Truck runs smooth as butter and oil temps when towing are excellent! Love Amsoil!

Been running AMS oil since the day the truck was borne. Lets see how well it does I have 90k on the truck now without a tic. I've never had a machine that runs AMS it's whole life fail mechanically.

I can already hear a huge difference in my engine.

A great product as usual. I am slowly swapping all my vehicle fluids to Amsoil.

I have used this for over 20 years and love it.

Brand new Kia K5 GT nothing but the best for her, with the help of amsoil this car will be arounf forever gonna break the kia stigma, lol thanks for the best oil ever amsoil ily 😘

I use amsoil in all of my vehicles. I feel that is why I obtain high mileage with little or no major maintenance problems. My 2003 Chevy truck now has 347,000 miles with no engine teardowns. It still runs like a top. My 2023 Envision with only 47,500miles I had oil change recently. I expect high milage on it also. It's not just synthetic, it has to be amsoil synthetic.

Fantastic! I switch over to AMSOIL Signature Series 5W-30 at 30K service, my trucks seems to be running smoother, I intend to stretch out my oil change to 7,500-10,000 mile instead of 5,000.

I think this is the best oil on the market. It’s the only one I will ever use in my Dodge 6.4 hemi

I love Amsoil products. They just work all the time.

No oil compares to amsoil. I’ve tried Liqui moly royal purple but amsoil is my top choice from now on.

Did an oil change in my 2017 Silverado using Amsoil for the first time. I was familiar with this product prior to the oil change, just got stuck in the convenience of a dealership doing it. That became costly and inconvenient. What I noticed right away was how much quieter and smoother the engines runs. My truck has a variable valve engine which I used to feel shifting from 4 cylinders to 8 cylinders and back again on OEM recommended oil used at a dealership. NO MORE….smooth in the transitions, starts better, quiet. Great oil ! Here to stay from now on !!

Great product but went to order my usual, no oil filter when it arrived. No biggie so I called and talk to a young lady there and she told me they were out of oil filters the AMSOIL oil filter so I went to my nearest auto parts house and purchased an oil filter for my 2025 Toyota Tacoma and that’s the end of the story

We chose Amsoil after research and testimony about its ability to withstand elevated temperatures during stationary turbo cool down. It is not the best at this, but does everything else better than those oils that do exceed Amsoil at this. So Amsoil is an overall winner. We lab test our oil changes so the honest review will be in about 3000 miles.

I’ve used Amsoil products for 15 years in all my vehicles, side by sides, motorcycles and machines. Every one still running strong without issues. I love the fact that all can be purchased as complete kits through Amsoil.

as always very pleased your product. Have been using it for years in race car and road cars
