You shipped an extra gallon of signature and didn’t charge me for it. I called and paid the difference. The right thing to do. See midwestern values below. Unfortunately it fouls up my purchase agenda, and winds up being a little less cost effective for a year. Not a big deal. As I said, I use signature, and it lasts one year and cuts down on maintenance time. I’m loyal to Amsoil and intend to remain so because I see it as a superior product, and customer service offers a personal connection far exceeding what has become the norm. I think it’s midwestern values. But that’s just me. I grew up in Illinois.

Amsoil has made my engine quieter, and improved my fuel economy. Very happy that I switched and I will be switching my differential fluid to Amsoil severe gear here soon as well.

On my 2006 Jeep Liberty with 88,000 Original Miles All other Conversational "Full Synthetic" engine oils made the engine have a tapping sound at start-up. But when I switched to the Amsoil the tapping sound stopped!! Been using it every since and will never use Conventional oils again!

I like knowing I’m protecting my engine and two turbos! No valve train noise and chatter . I use Amsoil in all of my vehicles and motorcycles. You definitely get what you pay for!

Best diesel oil on the market we protect our feet with amsoil.

I run only this in a higher performance engine

been using his product on my Silverado it has over 250000 miles on it and its running like new still best Whear protection I've ever had .

Excellent oil with great results. My truck runs smooth and no real engine heat issues during the summer. The Ford F150 with Turbo has the tendency to run hot. Truly, I believe this oil saved me from the dreaded oil leaks the F150's seem to get around 40 to 60K miles. Dumped all the manfactures fluilds and replaced all with the AMS OIL products.

Unlike many "synthetic" oils on the market , Amsoil Signature Series is 100% synthetic, and is very high quality. My engine stays cleaner and runs smoother , and I'm getting good gas mileage and performance as well. Much higher quality than the oil that Lexus/Toyota uses in their vehicles. I'd recommend Amsoil Signature Series oil to anyone who is serious about performance and maintaining their vehicle in perfect condition. It's so good that I got my family members to switch to Amsoil , and they notice the difference as well.

It is our first time using this product i can let you know later how it worked for us.

Great product. First time user, car seems to run smoother and quieter. As always, you pay for what you get !

Years ago I only used 20w50 for my Harley. But yeah was hard to get, a pain and inconvenience. But I'm back now! My work vehicle has approximately 2,000 miles on Amsoil engine oil and is the golden color still. I've drained the transmission fluid and changed the filter and it's smoother and both run cooler! The trans fluid is RED and still red just like it's supposed to be.The gas addictive has put a pep in the 4cyl step also! Amsoil products are almost to good to be as good as people say,but it really is absolute awesome stuff!!

Used on all 3 of my wife’s current/previous cars. All have been Ecoboosts that she would put on average 25k/year on in South MS heat. Last two cars made it 100-150k without any issues and always a clean engine and valvetrain with this oil at every 5k interval. Current 2023 2.0 bronco sport has 38k, quite valvetrain and smooth running as always.

I’ve used AmsOil now for just over a year. I have 4 vehicles, and going forward will only be using AmsOil products in all vehicles.

The price is good and the quality and shipping is great. Using on a 2005 gmc Yukon Denali with 208000 miles. So far everything is working good. Drove about 3000 miles with the new oil.

Have been using oil for couple years car is quieter at idle speed and runs smoother.

New to me Equinox 150k. Seems to run smother.

I like how they have the proof behind all of their products and that to a consumer adds trust and value knowing that it truly is protecting their engine in their vehicle

Oil pressure one up when switching to this oil

I have used the synthetic oil in my autos since - a long time ago! I wouldn't use any other oil in my auto.
