[Healeys] Oil Additives

[Kees Oudesluijs]

The main thing is to change oil regularly, at least every year, and use 
a good quality oil 20W50 oil suitable for classic cars. If you prefer a 
high level of ZDDP get a 10/20W50 for motorcyle engines as they can 
legally have a higher content of ZDDP.

No additives needed.
