"Myth: Mobil 1 will leak out of the seals of older cars.
Reality: Mobil 1 does not cause leaks. In fact, new Mobil 1 with SuperSynâ?¢ was tested in dozens of industry standard and OEM tests to prove its seal performance. It is fully compatible with the elastomeric materials from which all automotive seals and gaskets are made.
ExxonMobil engineers are wary of conventional oils that tout their use of additional seal-swelling agents. With extended use, these agents can over-soften engine seals, resulting in leaks. More to the point, an oil additive will not rejuvenate worn or damaged seals. The damaged seal may have been caused by a worn rotating metal component in the engine.
If an older engine is in good condition and does not have oil leaks, Mobil 1 with SuperSynâ?¢ provides the same advantages as when used in a new engine. ExxonMobil recommends taking measures to repair the leaks, then using Mobil 1 with SuperSynâ?¢. ExxonMobil also always recommends following the automobile manufacturer's manual for the proper oil to use."

sounds to me like they say you're ok as long as you don't have existing leaks.
