Used as directed . Seemed to “clean up” the old oil residue somewhat . Maybe just flushing out the residue with an engine oil change would work also.

Bought a used Tahoe with a slight engine miss and oil consumption problems. Poured the EPR in and ran the engine the directed time (added an additional 30 minutes) changed the oil and topped off the oil with 1 Quart of Marvel Mystery oil and misfire is gone and no oil consumption in 1k miles. Highly recommend this product!

Their products are great but over priced. Tecron is a fraction of the cost with same results.
