Default Re: Foamy Transmission Oil

Blockhead,


gear oils, unlike hydraulic oils for example, do not have an extravagant anti-foam additive. (This has a technical reason).

If you have driven your car before, a foam crown is normal even after about an hour. The thicker the viscosity, the longer the foam remains.
