2 bottles of Auto-Rx is 24 ounces (each bottle holds 12 ounces) at a ratio of 2 ounces of Auto-Rx per quart of oil. You have more than enough to begin cleaning. Follow the application for your engine. I guarantee it will do a fine job.Plus you still have 4 ounces left for the maintenace application(sludge)3 ounces (cleaning) the most important part of the complete Auto-Rx Process.
