Ever since I started using Amsoil products, I have noticed how much more smooth my engines run! I feel more confident I'm not going to have any problems on trips ,and in everyday driving.

Best oil on the market

Amsoil Products to me #1

I am a vehicle mechanic for more than 45 years and seen it all. That’s why I use, nothing but the best in my vehicles. Best oil products on the market. You can’t go wrong when using the Amsoil products.

I'm super excited ! I've been using your great products for several years , and I purchased a used 2011 Toyota Tacoma 4wd double cab in all stock configurations, with less than 50,000 miles , this truck has a 4.0 V-6 5 speed automatic, and before changes I was getting 18 mpg , I recently changed fluids in the differentials , transfer case , engine , and flush the radiator, heater core , and block used the heavy duty 50/50 mix along with using all Amsoil synthetics , and installing new spark plugs and air filters , , with no modifications to stock running gear , and in the bitter cold temps , snow and ice in Southern Indiana, this truck has seen an increase of 3 mpg , so fantastic work , on making an excellent product , that is far superior in lubrication properties , allowing this vehicle to move more freely, Thank You !

I had been running the OE full synthetic for years and thinking the signature series wasn’t worth the upgrade. Man was I wrong.. My 1997 f150 had been running 5w20 OE for years. Occasionally on cold mornings would tick for a minute or so on start up. This drove me nuts since I had done a basic overhaul of the entire engine. Complete with new Melling tappets, chain tensioners, chains and Ford oil pump. In a nutshell the only thing I didn’t do was remove the pistons. The cylinder walls looked great so I figured send it. That turned out to be a bad decision. I didn’t want to buy new pistons and rings and pay for machine work. I decided to make a switch to signature series in my most recent oil change and the tick seems to have resolved itself. Thanks AMSOIL

Excellent product

My wife and I both have non turbo motors with manufacturers recommend 10,000 mile oil change intervals. If I'm going to go 10k between changes i want oil that will last 10k. After looking into it and watching project farm we only use Amsoil signature with one ounce of motorkote. If it can keep her jeep from ticking it must be good oil.

At this point I'm on my 2nd oil change of Amsoil 5w30 Sig. Series. I switched from Pennzoil Ultra Platinum 5w30, which is also an amazing oil... But the 6.0 gasser in my 2013 Silverado likes the Amsoil a bit better.. Only have to top of with a fraction of a quarter of a quarter one time throughout 5k miles, versus nearly an entire quarter with Pennzoil at same mileage.. ALSO WORTH NOTING... When I first switched to the Amsoil I used the EA15K50 15k mile oil filter & IT LEAKED LIKE A SIV! Even after replacing with another of the same that Amsoil had sent out to me.. Not only that but at only 3,800 miles my oil pressure dropped seemingly overnight from 30 at warm idle (where it always is) to 15/20, as if the EA15K50 had gotten clogged... I am now using the larger 25k mile rated EA017 Amsoil oil filter & so far so good at about 4k racked up as of currently.. Still keeping my OCI's at 5k miles, however. Amsoil oil = THE BEST..... Amsoil oil filters however = questionable.

This was my first time using this product. I have used Motul for years on my 2016 Subaru WRX STI I noticed the difference right away. The motor was a lot quieter a bit smoother. Overall, I like the product and I will continue to use it.

Using this to lessen the damage done by winter cold starts on 5-30 vehicles

I have used the signature series oil in three oil changes in different vehicles over the last couple months and noticed a quieter and smoother operating engine right away. Time will tell if amsoil makes a believer out of me but so far so good.

I have a 2007 Tahoe with a 5.3l engine in it that right now has just under 320k miles on the clock. It has been running Amsoil products in it since it's first oil change. I my heart I believe the only reason it has made it this far is Amsoil.

Its the best/ I use it in my three cars. (FOR YEARS)

Very happy with this product, no complaints.

It's really not worth spending the extra money when it's recommended you change your oil every 3 thousand miles for the extension of the life of your engine!

I like it

The best oil to use for your engine. I am willing to pay a higher price for longer miles and better quality.

Best oil I can find. I change under mfg recommended interval by almost half. I've been a amsoil customer since I won a oil change at a outdoor show early 80s Couple trucks over 300000 miles. The bodies died not the motor. Amsoil!

I’ve been using this type of oil for 10 years or so on various vehicles I have owned. This oil has allowed my vehicles to operate quieter, has lowered the engine temperature, and has improved the performance as well. I have sold and passed some of my high mileage vehicles along to relatives and they are still being used. I highly recommend everyone to try Amsoil for yourself and find out how good it protects your engine’s life.
