3. You should be clearly that you can’t modify the structure of the engine.

4. if you need to change the spare parts, make sure that you use original spare parts. After-market parts might damage your engine.

5. The quality of lubricating oil using on mechanical B series engine should not lower than API CF-4/SG standard, the viscosity is 15W-40 or when using in the arctic climate 10W-30 and 5W-20. The quality of lubricating oil using on electronic B & C series engine should not than API CH-4/SJ Performance range, the viscosity is 15W-40 or when using in the arctic climate 10W-30 and 5W-20.

6. Your engine must use antifreeze anti-rusted solution, and should change the liquid timely. DCEC recommend to use composite coolant or 50/50 high quality water mix with composite anti freeze.

a. The high quality water should meet all technical requests: concentration of chloride is lower than 40ppm, concentration of sulfate is lower than 100ppm, calcium/magnesium is lower than 170ppm; the prior choice is ionized water, distilled water or softened water.

b. Glycol working range between 40-60% is acceptable.

c. The concentration of SCA is in the range of 0.3-0.8.
