1999 Taurus with 3.0 OHV Vulcan. Currently has 206,000 miles. OCIs at 5000 miles.
In the past I used synthetic until some leaks appeared. I used Maxlife, and leaks disappeared. Then started using MS5K for several changes and everything was good. Got a deal on Mag1 conventional and used it for 3 OCIs. Just put MS5K in the last change (205,000 miles) and within a couple of weeks an oil leak developed (re-developed?) at the front of the engine.
Coincidence? Maybe MS5K is using some Group III, which is causing leaks.
Comments???
