I have a question a 1996 Mazda 626. This car has 187,000 miles but it was running really good. I change the oil three days ago, since it has high mileage, I purchased a Wal-Mart brand motor oil that was designed for cars with high mileage. It ran on the new oil for 150 miles and now the engine started to run rough. I drove it home for about 7 miles and When I got home, I smelled a burned like smell and the engine light came on. It is as if the car is running with only three cylinders or so. The oil still looks very clean and it is at Level. It could be a coincidence and some thing else unrelated to oil change is happening? Could you help? The oil I used is called Super Tech SAE 10W-30 motor oil.
have the same problem?
