The best oil.I maintain seven vehicles so changing oil could be a full time job. I use Amsoil because it is the best oil made and the best filter in the industry. My twin sons just became 16. For their birthday I had them learn how to change the oil in their trucks by converting them to Amsoil . This oil seems to be better suited to my older VW Jetta than the other Diesel oils. I use less of this oil. My car has nearly 300,000 miles and has always used about 4 oz of oil every 500 miles. With this oil that amount is cut in half.

Excellent Oil=Long running pickup!I have a 2005 Dodge 3500 with a 5.9L diesel. From the first time I changed the oil or had it changed, I have been using Amsoil 5w-30 with the Amsoil Filter. The truck now has over 435,000 miles and just keeps going! I do a lot of Freeway driving all across the West, sometimes pulling a stock trailer. Amsoil products keeps it going. I average about 25-28 MPG, and do about 35K-40K miles per year. Thanks for keeping me on the road! Item Reviewed: Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD)
Perfect winter oilThis is my winter oil for my 1998 Dodge Ram 5.9L diesel. Use this oil with my Amsoil bypass system.....change to it in November (from 15-40). Have been using this as winter oil for many years with absolutely no issues, truck starts well whether plugged in or not. Item Reviewed: Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD)
Good oil!Was having some stiction issues with my 7.3. Was recommended this product by an oil specialist. Never heard of Amsoil before I used it. Seemed like my engine loved it as I could tell that it started right up and seems to have restored any loss of power. Stiction seems to have gone away even in cold start ups. Will exclusively use this product. Item Reviewed: Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD)
GREAT product!!This review is based on a van that I no longer have. I used Series 3000 in that van for years... I believe 3 years?? Perhaps 4. At the time that it suffered a rollover and was "totaled", the engine oil pressure (a major indicator of bearing wear) was exactly as high as when the van was new to me.

Excellent OilI've been using Series 3000 5w-30 in my 2005 Ram 2500 with Cummins engine for 5 years now. I change it once a year, every 20,000 miles (without sampling...vlimd faith). Truck had 140k miles when I bought it and first put in Amsoil....it now has 240k and runs perfectly. I will always use Series 3000.

I believe in Amsoil productsI have been using Amsoil lubrication in all of my cars, trucks, tractors and compressors since 1974. I am very happy with the results I have had with Amsoil - higher mileage, better cooling due to less friction and longer oil change schedule.

Jack Sandow, CEO, "Aquatic Research South", Waycross, GAI wouldn't crank up my 2001 Powerstroke 7.3 diesel without Series 3000 in the crankcase !! It's amazing protection, and allows me to only change oil when needed. The auxillary remote filtration system I purchased from Amsoil allows me years of worry-free protection !!!! NOTHING better !!!!

Series 3000 5W-30 Heavy Duty Diesel oilI've been using using this product in my 2001 Ford Excursion 7.3L Diesel. Change every 15,000 miles . 288,000 miles so far ! High pressure oil actuates the fuel injectors on this engine. Still on original injectors. I believe the full synthetic oil has helped extend the life of the injectors. Several of my friends have had to replace their injectors on similar Ford diesels. Looking to put 500k miles on my Excursion. Amsoil products in transmission and rear end as well.

Series 3000 5W-30 for the 6.0 Powerstroke engineI have experienced quite a few problems with the 6.0 Powerstroke engines and I can say that my 6.0 runs like a top after switching to this oil. As far as I am concerned this is the only oil that I will ever put back into this machine - it has made a noticeable difference, especially in cold weather. I was skeptical at first but this oil was made with the 6.0 in mind. The standard 15w-40 oils tend to get sheared down by the High Pressure Oil Pump meaning they are 15W-40 when you put it in the engine but it is not 15W-40 when it comes back out. Where the Series 3000 oil goes in at 5W-30 and comes out at 5W-30. Item Reviewed: Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD)

Chevy dieselI have used this product for years. I keep my vehicles for many years so important to keep wear under control. When my trucks hit 45000 miles I switch to Amsoil 3000 and have gotten longevity on all with no major engine trouble. Never had to plug my vehicles in, in cold weather. And I've had to travel upstate NY in very cold weather. Item Reviewed: Series 3000 Synthetic 5W-30 Heavy-Duty Diesel Oil (HDD)
