switched to amsoil years ago on a truck with 250000 mi. lifter noise went away still runs today

I have been using Signature Series oil in my trucks for years. When it is a new vehicle I switch at its first scheduled oil change. On a used vehicle, soon after purchase. I had a 2001 Silverado 5.3L purchased used with 22000 miles. Switched to Signature Series and drove it to approx. 98000 miles. Gave it to my son who went to around 150,000. Sold it they put about another 10000 on it and sold it again. Last I knew it was rusty but still running strong. As far as I know It has had no major engine work.

Most complete motor oil ever,will never put anything else in my 2017 Chevy Silverado.

I use the Signature 5W-30 motor oil in my 2014 Hyundai Elantra Sport. I was surprised the first time I changed the Amsoil Signature motor oil as to how dark the oil was when I drained it. Then it hit me that the synthetic oil was cleaning the engine from where previously the engine had only seen a multi-weight oil. One other thing I noticed is the engine temp. shows the motor is running cooler than it did before I started using AMSOIL.

I have been running this oil in all my vehicles for several years, and have been very satisfied with the performance of the oil.

My family has 4 vehicles and they all have Amsoil in them. I highly recommend using Amsoil.

Loving this oil

i use amsoil in my truck, engine,rear end, trans, and my motocycles engine, trans clutch and i totally rely on it. my truck had a howl in the rear end when i would back off on speed after changing the rear end oil to amsoul it stoplped i love amsoil and highly recommend it to all my friends.

So fare so good, I put amsoil in my 2016 Subaru impreza and she runs like a champ just like my 06 Chevy Silverado. I have been running amsoil in my 06 Chevy Silverado for a few years now and I have seen the benefits both in overall preformance and reliablilty, it has transformed from a ticking tapping noisy engine to a quiet and smooth running one, you can't even tell it's running most days, the truck only has 100,806 miles on it but I wouldn't put any other oil in it, as soon as I try it start the lifter tapping thing again it is kind of weird in my opinion so I think its safe to say that this truck likes its amsoil. But i thought to my self why not put it in mysubie and get the same benefits as the truck. Both vehicles have amsoil in ever oil driven/gear driven component and I am a believe in amsoil. I am think about trying it I'm my lawn mower this summer and in my snow blower this coming winter. Why not lol

Run this oil in my 2002 corvette road race car. Dry sump engine, need the best protection. Great oil and has not let me down! Thanks Amsoil!

I trust this oil and the other Amsoil products because they work. I know that the maximum vehicle life and best operating effectiveness come from due diligence in maintaining it properly. There is great comfort in knowing I didn't compromise with the products I used. Keep rolling!

Have been using this product for about 9 years on both new and used vehicles. With extended mileage, I only change 1X per year. Cars have performed flawlessly.

This oil exceededs my expectations by far. Before using this oil I would always have a faint ticking noise in my valve train. After using this oil it is so quiet i couldnt belive it. The oil life itslefs last an incredibly amount of time as well. One of my favorite things about amsoil ut leaves behind a small film of oil after u shut down your engine. So when u start back up it still has a small flim to protect your engine intell the oil is pumped up. I use amsoil in ever one of my vehicles

Our Subaru hemorrhaged out all of it's oil on a trip (16 miles) to our Mechanic. He later called us and asked what type of oil we used. When I told him Amsoil Signature Series, he said "keep using it; you were totally out of oil !!". Using it for 20 years now. Never had an oil related failure.

I use Amsoil in all of my vehicles (4) and I believe that's why they perform and last a long time!!!

I have used this product in my 2009 Civic since it was new. Now with 195000 miles It has never been in the shop except for tires and brakes and 100000 mile spark plug change. It still runs like it did when it was new.

I've been an Amsoil PC for around 10 years now. I love Amsoil products and so do all my machines! There is no better value for your money. I have never had any engine problems in anything I have poured this liquid gold into. My wife's 2013 Toyota Rav4 loves it!

The SS 0W-20 works awesome! I just wish it were a little cheaper in price, even with the PC, it is still a little bit high in my opinion. However, it is a great 100% synthetic oil. My 2015 Silverado with the 5.3 V8 runs a lot smoother and has more power with this SS oil in my opinion.

I use Amsoil in all of my vehicles as recommended. We just handed down a 2003 Toyota Matrix with over 200,000 miles on it to our Granddaughter. This car was still of high quality even though it was used daily on dusty and dirty farm roads; as well as highway. I hope she gets another 100,000 miles or more.

Used in my 2006 Ford Mustang GT, 2013 Ford Edge SEL AWD, & 2002 Ford Ranger. I consider it the best product available.
