Changing engine and trans. oils


(spurs) #1

when changing the engine and trans. oils i usually have the front of the car up on a set of ramps for ease of getting at. is this ok or should i have the rear on axle stands to keep the car level.

It’s fine for the gearbox, as the drain is at the rear I think.

You would get more dirty oil out the engine if it was level

I like to keep it level so trans oil doesn’t run out the rear of pan when loosening and engine oil drains out completely.:blush:

about how much oil will come out of the gearbox?


(Gordon) #5

Only what’s sitting in oil pan, about 3 /4 litres,if you keep it level when removing, minimal spillage,lay out newspaper to catch what does spill.:+1::blush:

The supercharged merc gearbox has a drain plug. Thought ZF would too.

You can get more out the gearbox in other ways if you wish.
Is it a weekend Car?


(spurs) #7

yes mainly weekends but usually longish trips, 200-300 klms.

I drained the gearbox from the drain plug.

I then Disconnected the gearbox cooler pipe at the front.
Left it for a week for gravity to drain oil down and got another 2 litres out the bottom

sounds the way to go, thanks.

They used a GM box on X300 XJR’s, the drain plug is on the left side and you can expect less than 4 litres to drain out.

That is the problem having a forum coving 3 or more models years!

Each XJR having a different manufacture for the gearbox!

Do we know what year/country the OP is in?
