For vehicle engine longevity I don't mess with conventional motor oil any longer. Why even bother risking the heart of your vehicle.

Amsoil has saved an engine when lost oil pressure and had to continue driving 200 miles. had to replace bearings but crank shaft was not damaged. I have increased gas milage.

Superior products used in all my vehicles

No complaints on the product although a free hat for my 2nd or 3rd review of AMSOIL products would be nice. (Not so subtle hint) Lol. I will say that packaging and delivery of seven quart bottles is always well done and delivered in a timely manner. Keep up the good work.

1995 Ford F 150 280000 mi 2005 Ford Escape 190000 mi both show no decrease in power.

I use Amsoil in every vehicle I own. With the extended drain intervals and excellent protection it is the lowest cost as well as the best oil you can use.

All products that I've used from AMSOIL are excellent! I would not use anything else!

I have used the Automobile oils, the outboard engine oils and lower unit lubrication . I have also used the new gun oil lubricants because they work. I give all of the products that I have used a 5 Star Rating. Their boat trailer wheel grease which must go in and out of the water is great also. After launch and retrieve I go down the road at 65 mph with splendid results! PJ

The thing that attracted me to AMSOil was the long interval usage of their synthetics. Only needing to change the oil once a year won me over and Amsoil is suppose to better protect engines on start-up. That's important in cold weather. It is quite a bit more expensive than conventional oil, but thankfully a person only needs changing this oil yearly which ends up being cheaper in the long run.

I can definitely tell when I'm not using Amsoil. I can feel it in the engine. When I do use it, the motor is smooth as glass at the stop lights, and I know over time, the wear and tear on a motor is minimal with it's continued habitual use. I use it on all three of my vehicles. I've used other full synthetics in the past, but I can tell the difference. AMSoil is superior. I feel it's worth the extra money to me.

Excellent product. Miles 175000+ change oil & filter once a YEAR

I use Signature Series 5W-30 in my 2002 Z-28 and my wife's 2002 Cadillac. Meets or exceeds MFG recommendations and has great detergent add packs. Cadillac has 120K miles and no oil related problems.

I've been a faithful customer and user of Amsoil products for almost 10 years now. I can say with out any doubt that it has been the single best product I have ever used in my automobile. My 2002 Suzuki XL-7 has been running on Signature Series 5W30 for 9 years straight and my motor feels like is hasn't lost a shred of power. As an automobile owner who takes absolute meticulous care of his machine, there is simply no substitute for Amsoil.

i sponser a motorcycle flat track racer and we get the best results with amsoil dominator.

I will be using this oil for the rest of my car is life

No problems are always a good thing. I've used this for the last 80K miles and have experienced no concerns. If a problem occurs, I will be concerned about the cause, until then I like this oil.

Best Synthetic made!! I use it for 20k in my wife's Subaru. Barely changes color!! Everyone should use this! One oil change a year!!

in personal vehicle

I've been using Amsoil for 20yrs. I believe it reduces wear and increases the longevity of my vehicles

I get great results and extended oil life as well as improved fuel mileage with this oil
