Touring High Tech Diesel Specialoil SAE 15W-40 | 5 L | Touring engine oil | SKU: 2044

Works great. I use it in my V8 Duramax with 270k miles. Doesn't loose a drop between oil changes, alwys looks good when changed a 7500 miles.

Great product it highly recommend it for the quality & the value it has the marks in all areas.

Muy buena calidad

WOW!!! F-250 2001 7.3 Powerstroke Honestly made it and sounds like a brand new engine. After properly done research regarding the oil codes / spec CK-4 for newer style engines, oils are more focused nowdays with DPF and other high tech components in mind, I emailed Liqui Moly customer service and they suggested this oil spec and viscosity, all I can say forget about any other synthetic oil brand I've tried Mobil, T6 Shell, Valvoline, and I will only buy Liqui Moly for the rest of my life, I FINALLY FOUND AN OIL BRAND THAT I FEEL 100% satisfied. The engine is extremely quieter and I just have aa few hundreds of miles into the LM oil but there is a lot of good benefits I've seen, heard the iddling is music to the ears and the cabin is really about 40% quieter must be from the previous T6 5w40 that was just replaced, oil seems tacky great protection, and consumption prevention, be prepare to take out your hpop reservoir oil out and refilling it with new for less contaminants. DONT OVERTHINK IT I AM A SPECIFICATIONS FREAK AND I AM LIQUI MOLY FOR LIFE NOW.

I really feel good about using this motor oil. Only complaint is that it got a little lost in the mail. But showed up in good order.

Wow! New F-350 truck after an oil change. Never seen anything like it, faster response, goes quicker. Not cheap, but worth it

My 3 year old Cummins 6.7 with low milage seems to run a bit quieter and smoother. I have noticed a small increase in milage (maybe 0.5 mpg) but again subjective. I have always used synthetic oils in my engines and will certainly continue to use Liqui Moly and their Ceretec additive in this motor.

Less internal friction, better fuel mileage.
