Great product for a 1999 Ford truck with over 200 k miles. Does not burn oil at all.

Product works very well as described.

Just received the oil report for my 05 Corvette, which has 125,000+ miles. I have owned this car for 18 years and have the oil tested at least once a year. I just switched to Amsoil from Mobil 1 the last oil change and the comments from the lab read as follows: Spotless results from this oil sample. Wear metals are some of the best we have seen in recent history after the longest oil change interval on the page. Five other oil change test results were shown, dating back to 2018. Metals like Aluminum, Chromium, Iron, Copper, Lead, and tin were down significantly. I am happy I switched all of my cars to Amsoil.

I'm running this oil in my 1999 Chevy Silverado 1500, with 220,000 miles on it. The motor runs quieter, and my oil pressure actually increased by about 10 lbs at idle. Why I don't know but I'll take it. I've always been happy with AMSOIL. I run it in everything I own.

Use it on my 2006 Toyota Tundra

Use it on my 92 Chevy 454 with 207K on it.

I have a 2003 Tahoe with 300,000 miles that had a slight leak. It had Castrol conventional for all 300,000 miles when I bought it from family member. It leaked like crazy when I switched to this oil. I went from a quart an oil change to almost one a week. I switched back and now I’m back to normal.

The oil is going on 3000 miles and hasn't lost a drop.

Excellent product

I change my oil and oil filter every 5000 miles with AMS Oil Signature Series Synthetic Oil (5W20), even though this mileage change interval is not required. My 5.7L Hemi engine runs smooth as silk, and doesn't consume any oil. I love this oil, as it keeps my engine running in tip top shape. I highly recommend it to anyone.

Just what my 2 L turbo needed.

Real synthetic goodness

I have been using this in my wife's Fusion since it had 80 thousand miles. We change the oil and filter regularly every 6 to 8 thousand miles. Last week, I had the timing chains replaced. The mechanic said that, at 250 thousand miles, the guides showed almost no wear and the internals of the engine look almost new. I will be using this for the next 250 thousand miles and will report on the condition of the engine at that point.

I saw some YouTuber saying this makes his car feel like new. I thought he was just exaggerating. But when I put it in my 147,000km Subaru, after around 160km, it felt so smooth that I can only describe as “a new car”. My car never felt so smooth. That’s with all kinds of additives I tried over the years. It’s like it’s made for each other! Not kidding!

I have used this oil in my Toyota Highlander since day 1. 100k miles and still runs like new.

Best oil hands down.

Nice product

I used the oil in the past and decided to become a member the oil makes my engines run smoothly and helps with little better gas mileage definitely recommend using the oil to find out for yourself

This oil--Amsoil 5W30 synthetic motor oil--is the best! My Camry's odometer reads more than 300,000 miles, and I've been using Amsoil synthetic oil in it since I bought it in 2004 with 71,000 miles on the odometer!! I very highly recommend Amsoil synthetic motor oil!!

Best oil for my 2019 Alfa Romeo. Great company to order from. Quick shipping and delivery. Highly recommend
