You probably don't want to overdo it. There's a delicate balance of seal swell and additive "affinity" for metal surfaces. I've heard one oil chemist assert that too much ester could prevent the proper bonding of detergent or antiwear additives on the surface, especially if fairly standard additive packages are used.quote:
