Another vote for autosol. Peek is very good too.
Before you think of spending money on shiny bits look at getting it rust protected. Waxoyl is a must if you own a classic car.
More importantly, get it running right. I recommend a trip to SRE in Amesbury. A session with Neil on the rollers will squeeze every ounce out of power out of it, and maximize economy, for £60-100.
