Q&A

I have a 2003 Lexus ES300 with 92,000 miles. I have a rear oil leak and plan on trying the Bar's Oil Additive before spending $2000 to have the Rear Main Seal repaired at the dealership. However, in the last few days, the car has lost acceleration from complete stops...just no pep. Never had a problem until now. No warning lights are coming on. The car starts right up, idles fine, just feels like it's hesitating. However, when it starts, a huge cloud of thick white smoke comes out the exhaust and then clears up. Could this problem be related to the oil leak or just coincidence? Any ideas?
