Still running

I have been using Amsoil in our 2006 Dodge Caravan since we purchased it used in 2011. It is still running well and not consuming oil at 202k miles. Has Amsoil contributed to our good fortune? I can not know, but i will not risk switching to another oil.
This was a nice upgrade for a 1997 Ford Ranger coupled with the high flow AMSOIL synthetic oil filter. Truck runs smoother and quieter.
Bottom Line
Yes, I would recommend this to a friend.

I have been using Amsoil products for well over 20 years, from cars to boats lawn equipment and motorcycles.
Anytime I get a new vehicle the switch is made to Amsoil.
I like this oil.I can change it once a year in a vehicle.That's not driven on a daily basis.
Bottom Line
Yes, I would recommend this to a friend.

We just bought a new 2025 Jeep Grand Cherokee at the end of 25, put 1,100 miles on it then changed the factory oil out to Amsoil. HUGE difference! Softer idle, quieter engine, smoother all around! I also run Amsoil in all 3 of our other vehicles so, I had to keep it in the Amsoil family with the new ride too! This stuff NEVER disappoints!
Bottom Line
Yes, I would recommend this to a friend.

bought to go in a 4.6l ford i spent 7000.00 rebuilding .
ford tech said to use this to try to get the rings to seal on the new engine hasn't worked completely but has slowed oil usage down to about a quart every 2500 miles. CHAINS AND CAM GEARS HAVE QUIETED WAY DOWN ALSO. IT SEEMS LIKE IT IS HELPING SOME SO I AM HAPPY.

Great product. I use it with a Wix XP filter. Do changes at 7500 - 10000 mile interval depending on when convenient. I have high confidence in the quality.
Received it promptly, first time using it so I have to give it some time before I can actually rate the quality.
Bottom Line
Yes, I would recommend this to a friend.

Does the trick

I used the engine flush to clean out my 1998 Toyota Tacoma due to the truck sitting there for 3 years with the same engine oil & I had inherited this truck from my pops. I must admit this flush cleaned out the engine & when I drained out the flush, it came out black as Texas Tea. I would recommend using this engine flush.
Switched to amsoil a year and a half ago. Engine temp was always around 200-202 degrees here in Florida, once I switched hardly ever goes over 190. Engine stays nice and clean.

I didn’t use it yet but I have experience with Amsoil. I use it in my Indian motorcycle for more than 6 years and it worked with no problems.
I never believed what I was told about this product until I used it. I have a newer vehicle with the typical valve train noise in the engine and wow it sure did quiet things down. Also engine runs smoother!
