Detergents & synthetic oil

[wavinwayne]

I often hear the statement made that synthetic oils contain more detergents than conventional oil. Is this true, and if so, why?

I'm taking a guess here but don't petro based base oils have a higher solvency then synthetic base oils. So with the synthetic base oils having a lower solvency they need more detergents.

There is no solid rule - a long drain synthetic oil may have more detergents or a race synthetic may have less.....

It's the whole formula and the application that counts.
