Cars need regular oil changes to keep them running in top form, just as winning racehorses need periodic blood transfusions to keep the drive for victory coursing through their veins. Treat your chariot like a champ with today's Groupon: for $30, you get an oil change, which includes up to five quarts of oil, plus a filter change and tire rotation at Cerritos Nissan (a $75 value). Today's deal is good for for Nissan and Infiniti vehicles only.

Cerritos Nissan's oil changes keep auto innards well-greased with the addition of revivifying streams of fresh-faced fluids. Technicians bolster mechanical heartbeats by swapping out grimy crude, extending engine life, reducing friction, and evicting broken-down debris from piston hiding places. A new oil filter assists the lubrication quest, catching truant gunk before it can clog up whirling parts or tape “Kick Me” signs to the transmission. Cerritos Nissan's meticulous techs cap off car care packages with a tire rotation, mitigating uneven wear or premature baldness by shuffling rubbers into new positions.
