I own a 1994 Toyota Camry V6 with 80,000 miles. The car is used mostly on short trips with 3000 mile conventional oil changes. I just finished my first complete AutoRx treatment. The auto runs much smoother but has developed a small oil leak.I know this a common occurrence and hopefully the leak will stop. I cut open the oil filter and saw the the AutoRx has cleaned the engine. My question is should I do a second AutoRX treatment because of the age and use of the auto or should I just do a maintenance dose of AutoRX.
