Ir visur rašo, kad sintetinis

Pagooglinau ir dabar is viso nesuprantu VAG'o

http://www.blauparts.com/audi/audi_fluid/audi_power_steering_fluid.shtml raso, kad G002000 mineralinis buvo iki 1990 tuju (CHF 7.1), veliau tuo paciu kodu patapo sintetinis (CH11s):

"Audi tech bulletin 48-89-T07 issued in November 1989. It states "The new [synthetic Pentosin 11S] and old power steering fluid [non-synthetic Pentosin 7.1] can be mixed if necessary ... the part number [remains] unchanged."

Tai WTF ant bakelio masinose net 2000-aisiais rase "use only mineral"
