“My name is Scott. I drive a 2005 F350 with a dreaded 6.0 and all I can tell you is I’ve been using this stuff since it first came out and Hot Shot’s Secret along with [Diesel Extreme] and the Blue Diamond Oil has saved that engine, and I know that because it’s a brand new engine. It’s also the third one that they’ve put in; so that’s all I’ve ever used in this engine. This engine is almost at 100,000 miles and I’ve had no problems with it whatsoever. I will continue to use Hot Shot’s Secret and I will continue to use all their products because Lubrication Specialties has landed on something that’s actually worth using over and over and over again.”
“I want to tell you that I have been running the Blue Diamond in my Yanmar tractor. This YM2000 has no starting aids, and prior using Blue Diamond, it was nearly impossible to start in the mid 20′s and lower temperatures. After installing the Blue Diamond, the temperature can drop into the teens, and the engine starts almost as easily as if it were 70 degrees, and the engine runs with much less mechanical noise.”

Blue Diamond is fully compatible with all conventional mineral oil-based motor oils and fortified with a high detergent 14TBN additive package with highly effective dispersants – making it suitable for all diesel engines where 15W40 is required. Its low volatility compared to conventional light neutral based oils greatly reduces oil consumption. The high detergency plus the exceptional oxidation and thermal stability prevents deposits and oil breakdown, making much longer drain intervals possible. Special anti-wear additives in superior lubrication basestocks plus super engine cleanliness spells elimination of most wear and reduction of maintenance. Blue Diamond is formulated for extreme cold temperatures as well as extreme high temperature service. Its 5W viscosity at low temperatures allows it to replace conventional 5W30, 10W30, and 15W40 oils in gasoline as well as diesel engines.
