The original lubrication system supplied by the manufacturer must be employed, save that oil pumps may be replaced or modified to enable higher pressure and/or volume, and additional external oil lines to original or approved components may also be employed. Any replacement oil pump must work on the manufacturer's original principle. Sumps as supplied as original equipment for the model in question may be modified to incorporate baffles and/or increased capacity. Oil coolers and remote oil filters are permitted, but the external bodywork must not be altered for the purpose of fitment, nor may they be fitted outside the confines of the standard bodywork. Dry sump lubrication systems are not permitted, unless originally fitted. Remote pressurised oil accumulators are permitted, conditional on them being used in conjunction with a normal wet-sump oil system and serving no other purpose. The capacity of the accumulator must not exceed three litres. Should the accumulator be mounted in the cockpit then the system must comply with the Manual Technical Appendix Schedule A (I)

Any holes drilled in inner panels for Oil Cooling pipes must be no larger than needed for the pipe and fitted with a rubber or similar sleeve
