Can't say more of how it helps performance and keep engine quiet and cooler while extending oil changes. Review: Great product that has significant results - Great product that has significant results! I had previously been using STP ultra in my vehicles the past 4 years which was an alright product. But after adding Polytron in my 2001 Infiniti QX4 instead, I have noticed a big difference in engine performance. The engine sounds more quiet and feels much smoother as well as improved fuel economy and restored HP. I like the fact that it cleans the engine and keeps it clean from sludge and other deposits, not to mention that it treats the metal of the engine reducing friction, as opposed to other brands of oil additives which usually just treats the oil. You wont get results instantly but you will notice the difference after putting at least 50 miles or so after you add polytron. Great if you have a lot of mileage on your vehicle. I would reccomend this product. ## Features - For use in automotive, marine, industrial engine (gas, diesel, marine, 2-stroke), transmission, differential, steering pump, gearbox, and other suitable equipment; compatible with all mineral and synthetic motor oils. DIRECTION: General application rule: add 10% by volume or 5% for automatic transmission. For a conventional engine (up to 6 Qt oil capacity), apply Polytron MTC during oil change: fill the sump with motor oil of your choice ½ Qt less than specified, then add ½ Qt bottle of MTC. - Scientific breakthrough Polytron Metal Treatment Concentrate (MTC) treats the metal surfaces, not oil; reduces friction significantly. Polytron does not contain any solid particles (i.e. PTFE, Zinc, etc) and is not viscosity modifier. Originally developed for military/government applications - Eliminates engine wear up to 95%; may increase engine life span by 200-300%; engine may be protected in the event of oil or coolant loss by adding 10% by volume. - Contributes to cleaner emissions, reduced engine/equipment operating temperature, improved performance – power, torque, fuel (mpg) and oil economy - Keeps engine totally clean of any deposit build-up and may considerably extend oil change intervals 300-700%; protection against extreme temperatures, dirt, and moisture ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BYFSCC8 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #323,636 in Automotive ( See Top 100 in Automotive ) #204 in Engine & Oil Fluid Additives | | Brand | Polytron | | Customer Reviews | 4.6 4.6 out of 5 stars (90) | | Date First Available | March 21, 2013 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.14 pounds | | Item model number | WV01RCA08288 | | Manufacturer | Polytron | | Manufacturer Part Number | Polytron MTC 16oz | | Model | FBA_Polytron MTC 16oz | | Product Dimensions | 1.75 x 3.75 x 7.5 inches | | Size | 16oz | | UPC | 187489000537 | | Vehicle Service Type | Multiple | ## Product Details - **Brand:** Polytron - **Liquid Volume:** 16 - **Package Information:** Bottle - **UPC:** 187489000537 - **Vehicle Service Type:** Multiple ## Images ![- Polytron Metal Treatment Concentrate Oil Additive (MTC) 1/2 Qt (16oz/473ml) Bottle - Military Industrial Grade - Image 1](https://m.media-amazon.com/images/I/71Erp18JXJL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best engine protection oil additive bar none *by A***C on September 26, 2025* Bar none the best additive for engine health and longevity.
