A. An 18.92 litre workshop bulk pack of BG Syncro Shift II — for fleet or workshop service of manual transmissions, transaxles, transfer cases and Haldex units requiring API GL-4 SAE 75W-75 gear oil.
A. A full-synthetic API GL-4 gear lubricant blended to SAE 75W-75 for manual transmissions, transaxles, transfer cases and Haldex units. Unmatched film strength and wear protection, excellent low-temperature fluidity, safe for steel/brass/copper alloys.
A. Compatible and suitable where Ford XT-11-QDC (WSS-M2C200-D2), GM Auto Trak I and II, GM Synchromesh, Motorcraft XL-12, Acura DPSF, Honda Dual Pump, Honda VTM-4, and Mercedes-Benz PN 900260315 are specified.
A. GL-5 gear oils contain higher levels of EP additives that can attack brass synchros in manual transmissions. GL-4 (BG Syncro Shift II) is the manual-transmission spec. Use GL-5 (BG Ultra-Guard) only where the application calls for it.
A. Yes. BG states Syncro Shift II may be effectively used in all vehicles where engine oil, ATF, or GL-4 gear oil is specified as service fill for manual transmissions — confirm against the vehicle handbook.
A. Yes. BG specifically lists Haldex units as a target application. For Haldex coupling oil service, confirm the specific fluid grade against the OEM's specification before deploying.
A. For noise caused by aged or out-of-spec gear oil, yes — fresh GL-4 with full film strength typically reduces gear noise. Mechanical noise (worn bearings, damaged gear teeth, low oil level) requires diagnosis rather than additive treatment.
