The Rochester Quadrajet was always a controversial choice. It's detractors, who sometimes called it "Q-Junk", claimed it was needlessly complex. Fans of the Q-Jet pointed out that it was nicely versatile and fit the needs of both the performance folks and the general public. It should also be pointed out that it worked in an era where emissions requirements started to play a serious role.

Todays' oils are lacking ZDDP (Zinc dialkyldithiophosphates) because of reports that they can damage catalytic convertors which is not a problem with a 1968 Corvette. Additives such as the Rislone product on the right does a good job of making up for the deficiency. The idea is to minimize camshaft wear. Some oils include ZDDP; when looking for an oil for your classic Corvette, choose one with more than 1,000 ppm (parts per million) of ZDDP.
