1) Product Introduction Dunba Nano Fuel-saving & maintaining Fluid for Limousine¡± is a fuel-saving environmental friendly multi-functional lubricant additives made by 2 Nano materials with anti-wear and self-repair functions, produced by technical equipment with our own intellectual property rights (Patent No. ZL200810032849.1) and new scientific and technological achievement by China 863 high-tech Project. 2) Nine functions Fuel economy: saving fuel and engine oil, 5%-25% oil consumption saved; Engine protection: triple strong protection to ensure that the engine is powerful in any work condition; Anti-wear: 80%-90% reductions in engine wear and tear; still provide superior protection under the conditions of lubrication system failure or non-oil. Self repair: wear and tear repaired dynamically, engine life extended 2-3 times. Fast start: superior lubrication function can significantly reduce the friction coefficient and improve the initial rotation speed. Power strengthening: restore the engine cylinder pressure. Power increased by 5%-35%. Noise reduction: effectively reduce engine noise and vibration. Corrosion prevention: prevent friction parts from corrosive pitting. Environmentally friendly: improve oil burning, blue smoke and other conditions, reduce exhaust particles by 20%-30% and smoke emissions by 50%. 3) Four Major Features Fast: engine working environment improved in 15 minutes, noise and vibration reduced, and power enhanced. Powerful: triple strong protection including inner reinforced, surface repaired and outer anti-wear by Nano-particles. Environmental Friendly: reduce exhaust particles and smoke emissions. No side effects: suitable for long-term use of various vehicles, without any adverse effects or side effects. 4) Two Major Breakthroughs Self-repair, Nano particle repairs the wear & scuffing surface automatically, then fundamentally achieving the engine maintenance; Four in one, Fuel economy, anti-wear, repairing and maintaining simultaneously. 5) Application This product can be easily and stably dispersed in all kinds of lubricants, suitable for various power system of a broad range of cars, the anti-wear and repair effect is more excellent for those vehicles run for many years and badly worn cars. 6) Usage methods Add this product to engine lubricant, keep the engine idle for around 2 minutes, or add the mixed product with lubricant. Normal usage about 3.5% of the total lubricating oil, in other words, for ordinary car, please mix 4 liters of lubricating oil with one bottle (150 grams). 7) Notice 1) Noninflammable, in explosive, in corrosive; 2) Don't drink and avoid long time skin contact; 3) Protect from impurity and water; 4) Keep in normal temperature and avoid sunlight. Boxes, 150g/bottle.
