Mobilube PTX (000.043.204.20) and Shell Transaxle (000.043.204.19) are GL-5 gear oils or are compatible with API GL-5 specifications.
Driven GO 75W-90 LS is recommended where SAE90 GL5 or GL-5 transmission/gear oils are desired; no additional limited slip additives are needed for models fitted with a limited slip as this product is already formulated with them.
