I don’t write very many reviews but this product is so good I had to let people know about my experience with Amsoil. first of all I’ve worked on cars and car audio systems for years and I’ve always used Valvoline because that’s what my dad used on his cars. I bought a brand new Challenger in 2019 and noticed it idled kinda of rough it’s a V8 and has a loud exhaust but I know cars and I could tell over the exhaust noise something wasn’t right. I thought maybe it has a bad spark plug or two or maybe a bad coil but I dismissed that because of the low mileage around 400 miles in 2019 I changed out the oil to Royal Purple at like 1,200 miles and nothing car still idled rough. I changed it again at like 2,400 miles same purple oil and nothing so recently I switched to Amsoil Signature series after watching a YouTube video and the response from my engine was immediate the rough idle went away instantly!! I was shocked and amazed the car has 4,000 miles on it and it idles like it now thanks to Amsoil.
I love the 25K Signature Series oil specifically bc I drive a lot of miles daily and it certainly saves me from having to change the oil more often. I’ve been using Amsoil for years now and have had ZERO issues with my 2008 Dodge Ram 1500 with 245,000 miles on. It. Coincidence? I don’t know, but I sure trust Amsoil and contribute the lack of maintenance on good Amsoil oil. I trust it 100% and for the price, well worth it!
For the first 50,000 miles I used another Synthetic oil and Just wasn’t pleased. I have used Amsoil for the subsequent 205,000 miles. I am very happy with the product and intend to keep the motor unopened for the next 250,000 miles
I needlessly worried about using this oil with the Chrysler Hemi Multi Displacement System. I needn’t have worried as this oil allows my Hemi to perform optimally. One of the nice things is that I have never gotten less than 20mpg on a fillup.
Try this in your hemi.
Only oil I use in my 2014 Mustang. Tons of track time and abuse to the motor and she still feels strong. My only gripe is that it takes nearly 12qts & I'm sick of having individual quarts - pouring one by one and dumping the old oil in one by one.... Amsoil really needs to make a jug size option for this weight of oil.
Love Amsoil products. We are experiencing hotter temperature for this time of year on the West coast. My 69 Camaro convertible (502 crate) running smooth.
Bottom Line
Yes, I would recommend this to a friend.

Amisol oil products are some of the best I use in my old 4 runner 1998 and still running strong.
I have used that oil from my first car until now and never had a problem. I had a 1990 Honda Accord with more than 300 thousand miles and I stopped using it when someone crashed it, totally lost. I recommend this oil without any problem.
I have used Amsoil in all my vehicles for over 22 years. All three vehicles run cooler and smoother because of these products. 1 of my cars had 280,000 miles before I sold it and it still ran like new. and I attribute it all to AMSOIL.
Use this in a bunch of different cars year round. Works great! Quiets down the engine compared to name brand oils. Lasts longer, better wear results then big brands. Worth the money! Fantastic oil.
Bottom Line
Yes, I would recommend this to a friend.

I use this on a V8 that is supposed to get 10w-60 but I really don’t see a reason for it since that second number shears down fairly quickly. This is quite stable after a year. I only put on 2500 miles annually so it’s nothing.
After using mobil1 for years, i noticed it wasnt lasting as it should and it would let the valvetrain make more noise. So i decided to try this in my freshly cammed L99 with a GPI VVT SS2 cam. Now, theres absolutely no valvetrain noise, my oil temps are actually lower, and my pressure is more stable. even on the hottest days i hold 28psi hot temp. Ill stick to using 8qt of this stuff from now on.
