Lotus Service Notes
340R
Lubricants are as for standard Elise. The maintenance schedule is basically the same except the distance
interval is reduced from 9,000 miles (15,000 km), to 6,000 miles (10,000 km) to reflect the likely harder use of
the vehicle. For normal road use, the engine oil and filter should be changed in accordance with this schedule,
but for cars used on race circuits, oil and filter should be changed every 3,000 miles (5,000 km). For seriously
raced cars, oil and filter should be changed every 2 meetings.
The engine is factory filled with Castrol GTX 15W/50 to be used for running-in until the After Sales
Service. At this service, it is recommended to use a fully synthetic oil for optimum engine protection, with the
following two products being specifically recommended; Mobil One 5W/50; Castrol Formula RS 10W/60.
A maintenance schedule for the 340R is available under part number LSL382.
