Engine oil vs Gear box oil?

[Tikirocker]

Just want some clarification ... I spoke to two different mechanics recently, both of which know and service Land Rovers - the advice given was to use the same oil for both engine and gearbox, not different oils. Apparently Land Rover recommend this themselves. I don't doubt their wisdom but was just curious to see what others are doing. Previous owner was doing changes every 5k for the County. Any thoughts?

What Landrover? Depends on the model, but yes, engine oil is the recommendation for some gearboxes.

But what gearbox? - LT95 certainly uses engine oil. Not sure of LT85 or LT77.

If its a 4 speed/LT95, then yeah, its usually engine oil used.

I would never use engine oil in a gearbox.

The mechanics who advised you that obviously have not kept up with modern oil technology.

Although engine oild were the original spec, there are a range of low viscosity gear oils available these days which are much better for LR boxes than engine oil. Do a search for the many oil posts by Rick130 and others on here.

I was advised by Mal Story (of maxi-drive fame) to use Castrol VMX-80 in my LT85. I have since switched to Castrol Syntrans which is better again.

The LT95 is a strong box, so can probably cope better than most with engine oil, however they are expensive to rebuild.

I;m running the 4 speed manual box in the County. The previous owner informed me that using the same oil for Engine/Gbox was recommended to him by MR Automotive at Redcliffe, who many would know are Land Rover specialists. The mechanic who did my pre-purchase inspection ( Who owns a Series 1 and drives it to work ) also agreed that using the same oil was the go

Two for two ain't bad, how wrong can they be?

If 2/2 people told you the world was flat, would you believe them?

I use engine oil in the LT95's box and Transfer

JC is the same last I knew

So easy just to have the one 20L drum

See Ben's comment. I have a Series 1 - the owner's manual states a different oil for TC / gearbox to the engine oil, so your mechanic isn't following what Rover specified for his S1 at least. Don't know about the LT95.
