A firm believer of Amsoil in turbos

I bought this product to protect the turbos for my f150 3.5L eco boost engine. In addition, the oil provides much needed fluidity during cold morning start ups. During the summer, you also notice cooler engine temperatures and slightly better fuel economy, even while towing.
Being a proud eco boost owner, I experienced a timing chain replacement at the dealership. When the engine was taken apart, they found that my engine was spotless in the inside: no varnish buildup at all. This was a concern with warranty because my truck went over the warranty period for this repair. Once the dealership reported what they had seen to warranty, they compensated the majority of the repair. I also told them I use Amsoil! And guess what... my dealership offers Amsoil oil changes too.
I do recommend if you switch over to Amsoil, do yourself a favour and get a bottle of their engine flush. With the oil filter and oil, you will do your engine right!
In 2019, we bought an Edge with the 2.0 L turbo eco boost and the first mod done was changing the oil. That motor runs great too!
I have been using Amsoil in my 30 year old Nissan Pathfinder 4x4 engine for 20 years and expect it to run at least another 10. I also run Amsoil in the transmission, transfer case and differentials.
Being trained as an Aircraft Mechanic years ago, when we first got into studying engines. The first thing we were taught was "OIL", This is the lifeblood of any engine! Change the oil on time or sooner and use a quality oil! This is the cheapest insurance for engine life! Since that day, I've always invested in the best oil on the markets. Ever since I found Amsoil, everything own gets Amsoil products.
I have used AmsOil products on 3 vehicles, i have used their oils, ow20 ss, motor oil, change intervals 10, 000 miles, also, my mechanic checks to see if it has stayed protective. i'll not use another product, because it is protecting my engine. Great Product and the folks at AmsOil backs it up!
I have been using AmsOil for about 10 years now and I have tried all the others. I am completely satisfied with all of their products. I use it in all my cars and toys.
Bottom Line
Yes, I would recommend this to a friend.

I have been using Amsoil in my cars and trucks since 1972. I have never been disappointed in any of their products. They have the best varieties and weight for any vehicle. If you want to change oil according to manufactures specs, or every 6 months or once a year Amsoil has what you need.
