2017 Sti grabbed extra 2psi off engine oil Car runs smoother This is Fiji water but for a car 5 stars!

I have used several different AMS oils from motorcycle to motorhome all work good.

I have used Signature Series in my wife’s Subaru’s for 18yrs. Never had any issues ever. I Run it between 15-20k. Never to 25k.

Upgraded my Mobil 1 High Mileage to this Science Beauty, you can definitely how smooth the engine feels, also I have use it in a car that I do Uber with and by the time it had 5000 miles the old Mobil 1 needed at least one more quart of oil. So far on Amsoil and 6000 Miles hasn't burn one drop

Meets the tough requirements of Dexos 1, Gen III.

SINCE PURCHASING NEW FORD VEHICLES WITH TURBOS I SWITCHED TO AMSOIL FOR DURABILITY AND LONGEVITY.

Frist I tried on my 2014 GMC SIERRA now I use it in my wife's car and My Cadillac Escalade

Cheaper than an engine warranty and more effective.

If you are serious about maintaining your car, this is the single most important protection you can buy. More expensive because it's worth it. I can change my oil every 10 -12K miles and the oil analysis is still better than other oils at 5k.

Have been using this product for over 40 years. Use Amsoil product for all engines.

Excellent oil. I keep vehicles long term, Amsoil helps tremendously!

Best oil in the world!!

Great product, used in both of my vehicles..really made a big difference in the valve train noise!! Much quieter and runs smoother.

I use amsoil in my car , motorcycle I know I get better Profromace in my engine and alot more miles

Excellent product! I am a Heavy Equipment Technician (Mechanic) 19yrs in trade. I have a 2010 gm that I’ve had since new 180,000km I used to run a competitors premium synthetic, oil change every 6 months or 5000km whichever came first. As well I’d use Amsoil engine flush every other oil change. Had a trip planned to go out east so did a full service on my vehicle, but due to high km’s decided to spend the extra money and used Amsoil’s 5W30 signature series. Two weeks and 7,843km later oil still had an amber hue at time of service and minor weep around seal had stopped. In my experience Amsoil out performed a long list of competitors never using anything else again! FYI if your vehicle has more 30,000km on it and you have been using conventional oil don’t change to a full synthetic it will burn oil.

Superior product been using in my vehicles for many years also in all my lawn equipment. I noticed ever since I've been using this product my lawn equipment vehicles run better smoother and less maintenance better gas mileage Great amazing awesome product.

Car loves it

I am using this oil in a 6.4 L hemi on engine start up. The engine has no lifter noise with this oil in it. as other oils that I have used in the past which I will not mention

Car engine sounds quieter

It gets and stays hot where I live. It is also dusty much of the time. So I have to know my engine is getting what it needs to prolong life. Ever since I watched Gail Banks three part tour of the Wisconsin plant I have come to know that I am using the best lubrication in all my vehicles including a fifteen year old bagger. Using Amsoil is the poor man's insurance policy!
