Switched to amsoil about a year ago in my 2015 JKU . Since the change I've noticed better starts and smoother acceleration. And small gains in RPM and power in 5th and 6th gear. (even with the ac on)
I believe this is the best oil on the market. I only use the best in my denali.
Bottom Line
Yes, I would recommend this to a friend.

I have been using Amsoil products in both my trucks for a couple years. Huge difference in quality and performance. I drive alot and no oil has kept up to how amsoil does. 10/10 recommend Amsoil products!
Solved my issues with lifter tick. Common issue on these 4.0l straight 6. Tried several other synthetics, AMSOIL is the best around.
Bottom Line
Yes, I would recommend this to a friend.

High mileage

So far so good. Oil changed 800 miles ago with this high mileage formula. Engine ran quieter after the oil change. Main reason for switching to this was because of burning oil. Was burning a quart every 5k. This oil hasn’t been in the car long enough to determine if that will change. Gas mileage seemed to get 1mpg better through 2 tanks.
All Ford F-150 5.0 Owners with issues, Rough idle and dies at stop lights, sends multiple codes Timing, cam position sensor, VVT.
After I took my 2016 F-150 165,000 miles, in for service, oil change, the check engine light came on and it started idling rough and dying at stop lights, when I talked to the mechanic he told me it was cam phasers and it would be cheaper to replace the engine $15,000. of course I got a second opinion, they said I needed to change the timing chain, and rebuild the heads $4,000.
I decided to do some research of my own, found that many Ford F-150 owners had the same issue, many different tried fixes none worked, Changing the VVT solenoids seemed to work for some of them, so I purchased one of them so I could see how they work, long story short the VVT solenoid is piloted by oil.
Oil in this engine is critical in the operation of the F-150s variable valve timing VVT, I looked back at the oil change records and they actually listed the brand and weight of oil they used in that last oil change Havoline 10W-30 and a Fram oil filter, that's when the problems started!!! So I decided to try an experiment. I drained 1-quart and added 1-quart of engine flush, ran engine for 5-mins, drained all the oil, installed a new oil filter from Amsoil, and filled with Amsoil high mileage oil, I noticed immediately the sound of the engine was so much smoother. the check engine light was still on, but it ran so much better, after about 50 miles of driving the check engine light went off, I've been driving it now for about 4-weeks 300 miles, no issues with rough idle and hasn't died at a single stop sign or stop light.
Thank You Amsoil !!! saved Me an engine replacement and a whole lot of headaches!!!!

Yes, I would recommend this to a friend.

Excellent Oil

I use this in a 2010 Chrysler Sebring with the 2.4 and have noticed the engine seems to run smoother and seems to have less friction
I have been using Amsoil products for over 20 years and the products have exemplary performance for all of the vehicles I have had over that time period. I Currently have 2 vehicles (a Chevy Tahoe and a Chevy Suburban) that are both over 20 years old and I believe that both of those vehicles have lasted so long ,in part, due to the Amsoil products I have always used.
I wanted one of the highest rated motor oils for my vehicle. I do a lot of traveling and I feel that I can rely on amsoil to be the best solution to help me keep my engine running the best.
Bottom Line
Yes, I would recommend this to a friend.

bottle crack / failure

the oil has always worked as advertised. I am very pleased. I do have a comment about the bottles. I had a case stored in the box for a coupel of years. the bottles were in their orriginal position and as it turned out, they were on their face. 4 of the quarts, 2 on the bottom row and 2 on the row above leaked. the weight of the bottles above caused each of the 4 bottles to fail (crack open) in the upper corner of the lable where the bottle above corner was pressing down on the lower bottle. I have always stored the cased in this manner and this was the first time there were any failures. Maybe you have changed the bottle design or thickness (resistance to cracking) in the material the bottles are made of. I have a pic if you want it.
