100% SYNTHETIC FLUID for Dual Clutch Transmission

DCTF2

【DUAL CLUTCH TRANSMISSION FLUID II】

  • It has better low temperature flowability that let you have smooth driving experience for the everyday driving and also we have improved high temperature oil film characteristic. It has advantage on high-intensity.
  • Because the stock fluid is very expensive and difficult to obtain, we have made it cheaper and easy to get for regular change and overhaul.
  • The base oil is authentic 100% chemical synthetic oil. (Stock is half synthetic oil)
  • We have analyzed kinetic viscosity for all range and accomplished stable performance of oil film in a high temperature for DCTF-1 or stock. It will prevent from gear attrition and improve the extreme pressure performance. Also we have adapted VW-DSG and BMW-DCT.

* The DCT's mechanism has gear and clutch work together. The stock is not to be changed but we recommend to change in about every 5000km because continuous racing participation make the clutch attrition component part that flow around in the oil causes the gear tooth attrition.

DCTF-1

【DUAL CLUTCH TRANSMISSION FLUID I】

for R35 GT-R/EVO X

  • Compare to the R35 (GR6) factory fluid, the flow properties at low temperature is improved so the ordinary use of the transmission can be smoother, and the oil film strength at high temperature is improved. HKS DTCF-I has more advantages than the factory fluid to high load driving. 
  • Comparing to the factory fluid which is very expensive and difficult to purchase, HKS DTCF-I is less expensive, and its availability is more reliable. Replace the factory fluid with HKS DTCF-I when overhauling and changing the fluid at regular interval.
  • The base oil of HKS Transmission Fluid is 100% synthetic. (The factory transmission fluid is made of semi-synthetic oil.)

*DCT(wet type) has mechanism of coexisting gear and clutch. And the stock oil is not required to be changed, however we recommend to change regularly (in every 5,000km) because of the continuously hard and sport drive make the friction of clutch parts to break which will cause to gear cog to be damaged.
