I haven't officially changed over to Amsoil yet, but I have added a quart and a half. Already the Caddy has responded in a positive way. I was getting a 100 miles per 1% average on my change oil meter. Now, I receive around 121 miles per 1%. Also, at 65mph my tach said 2500 rpm; where as now it reads 2350rpm. Can't wait to change over; won't be long now! So far, fantastic product! Getting mileage and performance ....

Great oil. Use it in everything I own.

I was using mobile 1 full synthetic and when i went to check the oil dipstick it would be a little dark but with Amsoil the color of the oil is the same as when i put it in. I believe it is the best oil for all vehicles. It is worth the money.

it’s like feeding your car organic strawberries. you see the picture?

The oil is not part of this review since the oil is the best. Trying to pour oil out of the gallon bottle is the only complaint. In short, it's a mess. There's no easy way to control the flow. I prep my new oil filters with new oil before installation. Trying to get a small amount of oil into the filter from the gallon bottle without making a mess down the side of the bottle is problematic.

I've been using this oil for years and it has never let me down. I run it 10,000 miles between changes in my GM LS-based 6 liter engine and do oil analysis at every change. The reports always come back showing better wear rates than overall averages for this engine. In fact, the lab results at 10,000 miles look so good that the lab I use recommends I could easily go 12-15k miles between changes. The engine has over 200k miles on it and I've been using Amsoil 10w30 OE for the last 100k miles. Before that I used synthetics of Mobil1, NAPA, and SuperTech (Walmart), with the same 10k change interval, and lab testing each time. Wear rates in the engine were often outside the averages with NAPA and SuperTech. Mobil1 was within averages, except for one category. Ever since I started using Amsoil, wear rates trended lower than averages, and my oil consumption between changes went down from about one quart to less than 1/4 of a quart. That's really incredible for a motor with over 200k on it that sees severe duty on a regular basis. And, as an Amsoil preferred customer, I'm buying Amsoil for the same price that I can get Mobil1 for at my local Walmart. I've used other Amsoil products over the years for my two-stroke outboards, dirt bikes, weedeaters and blowers. Always very pleased.

I've been using Amsoil products for almost 20 years. They have been great. The customer service is extraordinary.

100% synthetic protection at a more affordable price. It should be $5/qt though under the PC program...but still good stuff.

great stuff and if shipping was free at 50 bucks, ild order each month.

I have been using Amsoil for many years in my motorcycle and GMC 2500, I don’t feel like I need to worry if I miss oil change. I believe in Amsoil products, never had any problems

I am the owner of a 2002 Silverado 2500 Duramax which I purchased new. It now has 319,000 miles behind it and does not show a sign of quitting. It has always been serviced with Amsoil since it was new, and does not to this day consume nor leak a single drop. I have maintained a schedule of oil change at 16,000 mile intervals and have no notion of selling or trading. GO AMSOIL

Great oil only oil I use in my diesel truck

Second oil change with Amsoil. Engine runs much smoother fuel mileage increased. Excellent oil.

I started using Amsoil just over a year ago, and I have been absolutely blown away by its quality, and the customer service! I have been using the OE line exclusively, with nothing by great results!

I have used this in my 08 Silverado 2500 6.0 Vortec for years . I lost a radiator hose on the interstate and didn't realize for quite awhile . Pulled over ,called my mechanic and explained that I had just toasted my engine . It was HOT ! He called me the next day and explained that with 200k the compression was great in all 8 cylinders and asked ,what kind of oil do you use? When I explained that I have always used AMSOIL, his response was no matter what the cost it just paid you back and come get your truck . 250k now no problems
