Baader Machine-Grease #1 Teflon-Brown (-15°C–+55°C)

Currently I own a Vixen GP-DX SkySensor 2000PC mount (+25 years old). with good polar, 3-star alignment and a DSO not to low in the sky I'm able to shoot DSO's with pin point stars with an exposure time between 1 and 2 minutes carrying a Takahashi TSA-102. Nevertheless, it needs re-greasing because the last year the mount moves stiffer and stiffer and exposure times are decreasing. My question is which type of grease will best fit my old mount the Teflon-Brown or the Teflon-White. what grease would you recommend? With kind regards, Ronald Bemelmans
