BestLine Engine Treatment is a next-generation lubricant additive engineered to reduce wear, fight oxidation, and help your oil maintain its protective properties under extreme heat and load.

BestLine Engine Treatment is a next-generation lubricant additive engineered to reduce wear, fight oxidation, and help your oil maintain its protective properties under extreme heat and load. In an independent lab comparison featured by Lake Speed Jr. in his video “The TRUTH About Oil Additives Revealed (Real Test Results),” BestLine slightly increased PDSC time to 59.29 minutes versus about 50.95 minutes for the untreated oil sample, while several other additives reduced PDSC time in that same test.

Why enthusiasts choose BestLine Racing Engine Oil Additives.

BestLine is built for drivers who care about real test data, not marketing fluff.

• Helps your oil maintain thermal-oxidative stability under high temperature and load, as illustrated by the PDSC results in Lake Speed Jr.’s lab comparison.

• Reduces metal-to-metal contact to minimize wear in critical components like bearings, cams, and rings.

• Supports cleaner operation by helping oil resist breakdown into sludge and varnish precursors.

• Compatible with conventional and synthetic oils in gasoline and light-duty diesel engines when used as directed.

• Ideal for high-performance builds, towing, and extended highway driving where oil protection is critical.

In his educational video “The TRUTH About Oil Additives Revealed (Real Test Results),” Lake Speed Jr. ran a panel coker and PDSC (Pressure Differential Scanning Calorimetry) comparison on multiple additives, including BestLine Racing engine oil additive.

• At approximately 20 minutes and 44 seconds into the video, Lake reviews the PDSC data and notes that BestLine and BG MOA “ increased the PDSC time” compared to the untreated oil.

• The test results shown list BestLine at 59.29 minutes of PDSC time versus about 50.95 minutes for the untreated Pennzoil Ultra Platinum control.

• Several other additives in the same comparison reduced PDSC time significantly, with some dropping to the 30-minute range or lower, while BestLine increased the time under those lab conditions.

These results reflect the specific oils, additives, and laboratory conditions used in that test as described by Lake Speed Jr. in the video. Real-world results can vary based on engine design, oil choice, operating conditions, and maintenance practices. Always follow your vehicle manufacturer’s recommended service intervals and specifications.
