Black Diamond OUTLAW Engine Oil 15W40

The government mandated specifications for CJ-4 and CK-4 diesel oil removed a lot of the additives that made diesel oils so robust. Hot Shot’s Secret Black Diamond Outlaw returns these lost properties and is the most complete diesel oil available. It has the highest Total Base Number (TBN) rating and the highest extreme-pressure additive package, which includes zinc, of all our oils.

We chose our PAO Adrenaline Racing Oil as the starting point for Black Diamond Outlaw and blended in additional CK-4 additive, extreme-pressure additives and TBN Booster. At nearly a 15 TBN rating, Black Diamond Outlaw exceeds the CK-4 specification by 150% with nearly 3 times the amount of zinc mandated by API for the CK-4 specification.

The increased TBN provides you with unmatched protection against the acidic conditions occurring naturally in diesel combustion engines. The harder you run your diesel, the more protection you’re going to need. Black Diamond Outlaw gives you all the benefits of the latest lubrication technologies of a PAO oil, including molecular, oxidative, thermal and additive package stability, but now with extra protection that we haven’t seen in years.

Being 100% PAO synthetic, Hot Shot’s Secret Black Diamond Outlaw provides many more benefits than other synthetic or conventional oils. The high viscosity index of PAO’s requires fewer viscosity improvers to meet the weight specifications. The shearing of viscosity improvers will thin your oil by mechanical means while being pressed through main and rod bearings, camshaft bearings, lifters, and between valve stems and rocker tips. Reducing the amount of viscosity improvers needed in your oil reduces the amount of mechanical shearing that takes place. This keeps your oil from losing viscosity and keeping it in specification and providing you with a more consistent oil and engine performance.

The true synthetic nature of PAO’s keeps oxidation from occurring at high temperatures due to their chemical structure. PAO’s have a fully saturated linear arrangement that have alkyl functional groups attached which gives it unique oxidation resistance and cold flow properties. Your engine will be fully protected from wear on cold starts and during operation.

PAO’s are inherently cleaner oils as well, with less impurities from the start. This means your oil will start cleaner and remain cleaner throughout its life cycle. Our incredibly high zinc and antimony extreme-pressure additive package protects you from the worst possible scenarios when you need boundary lubrication. The synergy between zinc and antimony and their reactions with phosphorus and sulfur provide a stronger multi-layer of tribofilm at the surface than either component on their own, which adds even more anti-wear and extreme pressure properties.

As with all our oils, you get the friction reduction and wear protection of our triple patented FR3 Nano-Technology. If you’re looking for the most robust diesel oil available, Black Diamond Outlaw is the oil for you. Black Diamond Outlaw is not intended for vehicles with diesel particulate filters (DPF), catalytic converters, EGR or other emission equipment as damage to these systems could occur. Designed for Off Road use only.
