2018 Mazda CX-9- 60,971 miles.
Decided to do transfer case, differential, and transmission as it is due and we have some big trips coming up. To my surprise the transfer case fluid and differential fluid which call for 75W85 looked really good just an Amber color, no gray or anything unusual. Only oddity I thought was plug size: differential fill plug is 23 mm, drain plug is 24 mm and both on transfer case are 24 mm.
Both the rear differential and the transfer case got Royal Purple 75W90 with 2oz LG gear mixed in bottle. Common to use RP on these Mazdas as the spec calls for a GL4 requirement.
