Great oil, I use it in my 2006 Century Freightliner, I have over a million miles on it. Wouldn't trust any other oil.

I have a Chevy Silverado 3500 year 2008 410,000 miles on the truck love this product

I’ve been using this Series 3000 in my 2006 F350 with the 6.0 diesel. Yes the infamous 6.0. These are great engines built with extremely high tolerances that requires religious oil changes every 200 hours. By using the Series 3000 I have extended my hours up to 300. I could go more as per oil sample results. But typically this is right around the one year mark anyways. As you have probably heard, the 2006 F350 is one of the most stolen trucks in North America. I can attest to this as mine has been taken twice now. Once from work and once right from my home address. Yes I have a security system on it now. But back to the oil. In both thefts, the engine was abused enough to crack the heads and ruin the turbo. Yep. Both times. But the bottom end of my engine has never been touched and I have not had to change my high pressure oil pump either. I am pushing close to 400,000km on it now and it still pulls hard. I purchased it with 120,000 km on it and immediately changed over to Amsoil and put a 75hp tune in it. Other than the thefts, I have never had an issue and I run it year round, summer and winter. Would never think of using anything else.

Over 200,000 miles on F-150 using this oil no issues what so ever with engine.

Have been running in 04 duramax 3/4 ton for 100,000 miles with regular oil change intervals between every 3500 to 5000 miles in a work truck that has towed heavy loads or been under stress for most of its life. Switched to synthetic amsoil at 65,000 miles in engine, plus transmission and all the boxes. Has 179,000 + miles on it now and is still running and working strong. I believe the amsoil and regular oil change intervals has made a difference in the longevity of trucks power train components.

I recommend AmsOil products all the time to friends and family. Well worth the investment.

it's a good product but I don't like the gallon jug design. They're hard to pour.

Have used this oil in my Duramax since it finally broke in at 70,000, I now have 255,000 on it and every oil test came with 50% oil life after 10,000. I do a lot of short trips along with really long trips towing.

Makes changes a snap in my duramax. The 2 1/2 gallon jug fills her to the top of the stick. Great product and easy to order too

I have used amsoil in my 2003 dodge ram 3500 the oil, performs very well has always checked good with an oil analysis 222,000 miles without ant oil related problems towing horse trailers and now a 36ft 5th wheel

Very good quality.

Boatload of additive for Excellent TBN analysis between extended oil changes.

I use this in my 98 Dodge Ram 2500HD with the 5.9L Cummins 24v engine. It's been great to the engine.

This motor oil is used in my F250 work truck. I've been using it for around 130,000 miles

Great lube. Have used in gas and diesel motorhomes

Great product. I have used this oil in this truck for 20 years. I find it runs as good as the day that I bought it.

2004 Cummins 5.9 300000+ miles still has cross hatch in the cylinders

I use this oil in my 2006 Duramax with 180,000 and my 2006 Mercruiser. Oil works great.
