Need to change my engine Oil and Gearbox oil for a Defender 110 TD5 2001.
Would like to go for a synthetic oil.
The car is in South of Morocco now and I am told locally that I should go for a more fluid oil.
I am being recommended a 10 W40 synthetic .. does that sound decent ?
If yes what brand do you recommend ?
As well what Gearbox oil should I use for the car ?
Id like to change the oil but know nothing on this.
Bst, K Flitti
