I have been using this in my wife's Fusion since it had 80 thousand miles. We change the oil and filter regularly every 6 to 8 thousand miles. Last week, I had the timing chains replaced. The mechanic said that, at 250 thousand miles, the guides showed almost no wear and the internals of the engine look almost new. I will be using this for the next 250 thousand miles and will report on the condition of the engine at that point.
I saw some YouTuber saying this makes his car feel like new. I thought he was just exaggerating. But when I put it in my 147,000km Subaru, after around 160km, it felt so smooth that I can only describe as “a new car”. My car never felt so smooth. That’s with all kinds of additives I tried over the years. It’s like it’s made for each other! Not kidding!
Bottom Line
Yes, I would recommend this to a friend.

I used the oil in the past and decided to become a member the oil makes my engines run smoothly and helps with little better gas mileage definitely recommend using the oil to find out for yourself
This oil--Amsoil 5W30 synthetic motor oil--is the best! My Camry's odometer reads more than 300,000 miles, and I've been using Amsoil synthetic oil in it since I bought it in 2004 with 71,000 miles on the odometer!! I very highly recommend Amsoil synthetic motor oil!!
It hit me one day, when I realized the founder of AMSOIL had an aerospace background, he got the name from aerospace standards for all types of materials: A erospace M aterial S pecification. That's what sold me on the product. Thanks Al!!!!
I have been using 0w40 in my ram 6.4 gas enegine since new. Currently 67,000 miles and no hemi tick. Fingers crossed this helps prevent premature failure.
I've been using this oil in my 2002 porsche for the past 5 years engine runs super smooth and has more power. Since then I've changed all the oils in my cars to amsoil.
Bottom Line
Yes, I would recommend this to a friend.
