Thanks razorlab, that datasheet doesn't explicitly list "G4" though?

Thanks @razorlab !

Also, if it makes you feel more comfortable about the oil, I used both Motul and Liqui-Moly in the rear diff all last season. 22 track days or so.

Bunch of other track guys use that oil as well, some even go to a heavier 75w140

Good to know, leaning towards the Motul. I'm probably being overly proactive but in my previous Camaro SS 1LE it was strongly recommended to change the rear diff fluid quite frequently for cars that got tracked/autocrossed. After a season of autocross/track in my Supra I'm doing the same.

FYI I did reach out to Liqui Moly directly and below was their response:


hi,

thank you for contacting Liqui Moly support.

Unfortunately we do not currently offer an appropriate differential gear oil for your 2019- Toyota Supra. St this time we suggest contacting your local dealer for the proper fluid.

Motul Gear 300 75w90 or Liqui moly you linked. Don’t pay $80 for oem, that’s insanity. Especially since it actually costs $45.

@concept got taken for a ride.

My car is under warranty and needed just a couple of ounces to top off the factory fill. I dislike mixing different oils. That's why I chose BMW fluid.

Motul 300 75W90 has two versions, the regular 300 (105777) and the 300 LS (105778). Which one do we use?

Motul's website recommends the 300 LS for the Supra. However, the 300 LS is a GL5 while the regular 300 is GL4/GL5.
