After fitting hotter NGK Bp5 plugs and taking my Ruby out for a 50 mile run without a hint of its normal sooting up, I removed the plugs and found them to be a very light grey in colour.
The car ran very well and pulled cleanly up the many hills round here in West Yorkshire.
I am a little concerned that the light grey may indicate too weak a mixture and wanted to make sure that I am not going to cause engine damage . If I remember correctly the ideal plug colour should be more of a beige colour ?
Can anybody please advise.
Regards
Joe.
