AMALIE XLO Ultimate Synthetic Blend 15W-40 Engine Oil (160-79106-56) 1 Quart Bottle, Pack of 12 | Made in USA

This is great oil

Good oil at a great price. I have run delo, rotella t6 and some other full synthetic oils and this oil is cheaper and comes back with better or just as good sample testing when do for change. (500 hours in my application)

Product arrived promptly and well packaged. Using the oil for a Cummins 380 IXL Motor home engine.

Cheap oil I guess it works

Really impressive oil, noticably slippery, more so than any other oil, give me the feeling that this is some really good stuff.

I use it for my truck down to my lawnmowers. Good stuff.

This is great Oil! I use it in my 2005 Cummins.

This oil is 100% synthetic, means no conventional oil. Full synthetic has conventional oil as part of this formula. This oil contains molybdenum. I'm a helicopter mechanic and have used "moly-B" as we call it. This lubricant helps to keep aircraft from crashing, so it is definitely a plus as an additive to oil. I have put a few thousand miles on this oil and my vehicle seems to perform better than when I was running full synthetic oil. I have a 2003 Ford 6.0, and did have to do some research to confirm compatibility, as there is no mention of it on the bottle, but that time was well worth it. I've had my truck 9 years and have run diesel compliant full synthetic, and since I've been driving with this oil, I can't see myself going back to full synthetic. Let's hope that they keep this oil at this price point for the 4 1 gallon pack, as I have seen oils not as good as this going for more. My injectors sounded much better immediately after switching to this oil. So do yourself a favor and make sure you got good batteries, alternator, FICM, and Amalie XLO 100% Synthetic. I'm at 180,000 mi on the odometer, and it has not run this good since I bout it with 50,000. and the injectors are stock!!!
