Editing Coolant (section)

==Lotus==

===Elise S1===
The Elise S1 contains a Rover K-series cast aluminium engine.  The Elise S1 owner's handbook recommends only using Unipart Superplus, which was green, and a change interval of two years.  Unipart Superplus is no longer available, but similar non-OAT coolants are. The "official" Xpart coolant for the K-series engine is now a red OAT coolant, available [https://www.eliseparts.com/products/show/84/608/lotus-approved-engine-coolant/ at EliseParts].  Many S1's have been switched to the red OAT type at some stage of their lives, which should last approximately 5 years before needing to be changed, although the official Lotus service interval is 4 years.

Either IAT or OAT coolants can be used in the Elise S1.  The important thing is not to mix them, and to flush the system if changing from one to the other.  Modern OAT coolants ("pink", G12+/++, G30, etc) are more forgiving about being mixed with other types.  A HOAT coolant (Unipart AFC, blue) was briefly listed as the official coolant for the K-series in the MGF around 2000.  Check the levels regularly and refresh at the recommended interval.

===Elise S2/3===
Rover engined cars use the same coolant as the S1.  The recommended coolant for Toyota-engined cars is Havoline XLC.

===Evora===
The recommended coolant for the Evora is red PETRONAS Paraflu Up (previously orange Havoline XLC), an OAT coolant.  The change interval is four years.  USA?
