The problem here is not removing oil but putting it in.
The first job is to remove the Speedometer Cable and speedometer gear from the gearbox and remove the speedometer gear to check the oil level.
If you need to add or refill oil you’ll need a funnel and suitable length of hose (nobody said this was easy). The original Mobil oil specified by Lotus is no longer produced. Lotus now recommends Castrol TAF-X 75W/90, which is readily available and recommended for the S2 Elan which uses the same gearbox as the S1.
Draining the gearbox is simply a case of removing the transmission drain plug from beneath the car.
Capacity and recommended lubricant
Lotus manuals state 1.8l / 1.9 US quarts as capacity for refilling a drained transaxle, 1.9l / 2 US quarts if filling a dry transaxle.
Recommended lubricant is discussed at length in this forum thread and this one. Bottom line: 75W-90 GL-4 (or GL-5) full synthetic gear oil.

Some may have one. Some may not. Read on!
