I am in a situation where I cannot get the correct oil but I have to do a bit of driving for a couple of days before I get the correct oil.
Background: The seal was gone, changed the seal at home, now lack of oil in box – waiting to get the correct oil delivered. But need to on the road now. Can get the other oil around the corner. I can get something with the following spec: Huile pour transmission mécanique (Mechanical transmission oil) Performances exceptionnelle (exceptional performance) Larges plages de températures d'utilisation (Wide temperature ranges of Use) Viscosité 75w90, API GL5 What can go wrong if I use this oil for a week or so? Thank you very much in anticipation |

Shouldn't be a problem if it's only for a week, obviously change to the correct spec as soon as possible. -- 2010 Defender Puma 90 + BAS remap + Alive IC + Slickshift + Ashcroft ATB rear 2015 Range Rover Sport V8 Supercharged

Moment
isn't it so the transfer case takes GL5 75w90 as standard? The MT82 main gearbox takes GL4 as far as i know the GL5 is newer/higher standard and approved for hypoid gears while the GL4 is not. See no harm in using GL5 where GL4 is the minimum standard, opposite can be a problem if hypoid gears are used (both being 75w90 of course) correct me if i'm wrong please  |

From MartinK post: “ Engine, Gearbox & Transfer Box Oil Change”
Transfer Box "Refill to the level plug (2.4 litres). I used Fuchs Titan Race SYN 5 75W-90 Fully Synthetic Gear Oil (was Silkolene SYN 5 75w-90) - this one's GL5. " I understood that as the requirement – but maybe I am wrong? |

Yes - that's correct. Gearbox is GL-4, but the transfer box is GL-5. Defender "Puma" 2.4 110 County Utility (possibly the last of the 2.4's) |

Apparently GL5 spec oil affects bronze parts in gearboxes but I'm sure a few days would be fine
