Here is some authentic MGB motor conversation from the Moss Motors website. Obviously it's about breaking in the little engines and the oil to use during that process. It's a good read. The best thing about it is that it's short! Nice and short...

If you read into each of these threads you will notice that the name Valvoline is brought up more than a couple times. I'll have to read the back of one of their oil bottles when I go to the shop again.

Both links are good reading and MG and MGB specific. Two Thumbs Up!
