Subject: Re: LG6 rear axle oil (same as LG45?)
I spoke with Castrol's technical department today. They thought their Syntrax 75W-140 would be best, given motorway use and longer journeys (more heat in the axle), but if shorter journeys the norm, Syntrax 75W-90. Both oils are full synthetics, but one big proviso is that the 75W-140 is aggressive to "yellow metals". I don't think the LG6 rear axle contains any brass or bronze components, except perhaps drain and level plugs; as non-moving parts, would they be affected?
