The best oil I have ever used.

I have an 08 grand marquis and was a regular user of royal purple.
A mechanic suggested that this oil was superior to even that product and he was correct.
Longest lasting between changes, and the rattling on cold start of that these motors are famous for has been completelty elimated with the superior lubrication, also a slight overall milage increase, slightly less than a mile a gallon, but it was immediately noticable after the first tank.
The only thing I can say that was a little worse than royal purple is slightly higher evapoative loss or consumption., only a cup or so more between changes.
Clearly worth the money and one of the best things you can do for you money without rebuilding it.
Bottom Line
Yes, I would recommend this to a friend.

I have been using Amsoil motor oil in my vehicles for more than 20 years. My current vehicles, one a 2004 model and the other a 2005, each have over 160,000 miles on them. I have used Amzoil Synthetic 5W-20 wt engine oil in my vehicles since they were purchased back in 2005. The engine performance has not degraded over the years, and is about as good today as when they were purchased. I recommend this motor oil.
I have been using this oil for the life of many of my cars, as well as used ones I have bought. Keeps the engine clean (rebuilt an engine in my truck that I had been using this oil on since 157K miles and the engine had 260K when rebuilt) and the rings, and seals happy.
No doubt that Amsoil is the best, proven through testing, engine oils on the market. I have used them for over 40 years and, always am satisfied with the great protection I receive for all my vehicles.
Best oil to run in both new and older vehicles. I run this in both my newer and older vehicles and this oil helps a lot when warming the engine in cold weather as well as keeping it cool. Engine response is noticeable better running this oil as ECT temperatures are lower. Vehicle makes heat a lot faster now also.
If you read my other review for the European motor oil, I mentioned that I had also purchased motor oil for my truck. I believe that AMSoil Signature Series motor oil is either better than or on par with the best motor oils in the market, including German made Liqui-Moly. For any given viscosity requirements, if the selection includes Signature Series, I will always opt for this more expensive oil instead of the less expensive AMSoil OE series.
This is the only motor oil I’ll run in my vehicles. I’m a big believer in getting what you pay for, and while it’s a tad more expensive than big box oils, you can’t put a price on the piece of mind knowing that you’re running the very best oil in your engine. Worth every penny!
Bottom Line
Yes, I would recommend this to a friend.
