Why would a tamper seal be installed when I took my vehicle to a meineke shop for an oil change? When it says memo on slip & the shop offers free towing, need I now be worried something is wrong with car? I called & asked why a Tamper Seal was installed & informed that it was placed & if someone else were to touch it other than their shop, their shop could tell. Does this mean I have to take it back to a meniecke shop for oil changes in the future or something bad will happen to my car? Tha mis for answers in advance.
