bottem end rebuild

[ashills]

Stones... no:shock: but it obviously has much less protection than a good synthetic oil.
One of the reasons it's proscribed during the run in period is to allow a little wear on the rough... synthetic would protect them too well and not bed things in.
Now that you have removed the tough, that's all mixed with your mineral oil and running through your engine. Some of which may not get immediatly caught in the filter.
With a greatly increased bhp engine, I would be reluctant to rag it with mineral oil in at any time.

it was a joke mate i just meant 300-500 miles of running in on mineral oil and putting the engine under lots of different loads etc isnt gonna hurt it

No probs....;-)
As we were talking theory, I kept it that way.
Every oil has it's uses ah!
