Servicing for the Elise is different for the K-series and Toyota engined cars
There are four types of services for the K-series engined Elise:
These run on the sequence A, A, B, A, A, C.
Servicing Sequence Type KM / Mileage or time:
Note that for some variants (Sport 160/190, Exige), the service interval is every 6000 miles instead of the usual 9000 miles. Many advocate a service sequence of A,B,A,B,A,C on these cars so that the spark plugs are replaced every other service. Apparently this is what Lotus always intended but some service record books were printed incorrectly.
Lotus have amended the original schedule and now recommend changing cam belts at least every four years rather than the original six, this will often mean services can become "A+belts", "B+belts", or "C-belts" depending on age and mileage and you will need to track the age of the cambelt separately from the normal service history.
The synthetic cam belt used on Rover powertrain Elise models is subject to age, as well as usage degradation, and will be adversely affected by any contamination with oil or coolant. In order to bring cam-belt time servicing in line with current Rover recommendations the Service Schedule for all Rover powertrain Elise models was revised in October 2003 to stipulate a cam belt replacement time interval of 4 years (54,000miles/90,000km), with an inspection every 2 years (27,000miles/45,000km). For 340R/Sport 160/Exige models, the corresponding distance intervals are 36,000miles/60,000km, and 18,000miles/30,000km.
Toyota Service Schedule
Toyota engined Elises share the 9,000 mile/12 month service intervals of the K-series cars, but does not follow the same pattern of work.
The majority of the servicing remains the same each year, with transmission oil check every 3rd service and replaced every 6th service, air filter replaced every 3rd service, and spark plugs replaced every 6th service.
For supercharged cars (Elise SC, Exige S) the supercharger belt is replaced every other service.
