Adding a full can of Sea Foam to my Chevrolet Malibu’s oil [SOLVED] Asked by Latara J. In Michigan I added 1 can of Sea Foam to my Chevrolet Malibu at once. Will that do harm to my engine?
Thanks for the question Latara. Though one can is twice the recommended amount, you should be OK… just check and watch the oil color after driving. If it goes dark fast, then replace the oil.
