A fully synthetic oil for transmissions with a double clutch. The principle of the DCT is based on the use of two separate clutch-sets, one for the even and one for the odd gears. This transmission is further developed for use in cars of VAG, Mercedes, BMW, Volvo and the PSA group. A special oil, combining the extreme pressure capabilities of a manual transmission oil with the friction properties of an ATF, needs to be applied. It is composed to withstand the most extreme circumstances.
