How to Service Your MGB Service Intervals

Servicing your own classic is an easy and satisfying job, as well as that regular servicing will extend the life of your engine and increase the time between rebuilds and reduce the chance of breakdowns. All of the parts required to service the MGB are readily available and are quite cheap but it is important to buy good quality named components if possible (I had one set of points break and a duff rotor arm).

Classic cars need more maintenance and servicing than a modern car as there are few if none of the electronic gadgets. This does not mean that classics are pain and are always in the garage being fixed. The following is the recommended service intervals and maintenance schedule on a classic as given in workshop manual.
