Recently bought a Micra K12 for my daughter to learn to drive, With any car I have bought I always give the car a full service replacing all fluids, Plugs, Belts etc. I normally will use OE parts and fluids.
 
	I was originally quoted £51 for 3lts of gearbox oil (Nissan MT-XZ Gearbox 75W-80 KE91699935) but when stock had arrived was told it was a mistake and it was £105 (KE91699071) (£105 seems way too much for 3ltrs of oil)
 
	I was looking at GSF, Eurocarparts and Halfords. Getting a lot of conflicting recommended oils (75w80 or 75w85 Gl-4 I think is the recommended oil, no mention of synthetic or mineral)
 
	Comma's and GSF recommends - EP75W80 Plus (Mineral)
 
	Halfords recommends - Comma Gear Oil SX75w/90 GL-4 (Part Synthetic) Wrong Grade?
 
	 I noticed Comma Fully Synthetic MVMTF 75W80 Plus GL-4 lists under compatibiliy suitable for Nissan MT-XZ, Nissan MT-XZ TL (JR Type) but no website lists it as compatible.
 
	Can anyone confirm which ones would be suitable or could recommend another brand? Many thanks in advance
