2001 Toyota Corolla Burning Oil
I have a 2001 Toyota Corolla which I got used that for as long as I can has burned oil. It wasn't until recently that I learned that burning oil was anything other then a nuisance. So I am looking for some advice on how to fix the burning oil problem.
The corolla has around 72,000 miles on it currently and I normally run the manufacturer recommended 5W30 oil.
So the three easy solutions I heard when researching was;
1. An engine/oil treatment of some sort. I picked up a bottle of Lucas Complete Engine Treatment and added it to both the oil and engine earlier today.
2. Use a heavier weight oil such as 20W50 or W30. With the Lucas I also added maybe a quart and a half of 10W40.
3. Replace the PCV. I have not looked into how to replace it but since it is only a $5 part it might be worth a try.
So I am wondering if anyone has any experience with fixing a car that burns oil at and has any methods or products to recommend. I have heard that the various engine/oil treatments are snake oil and don't work or work well. I also heard that the heavy oils like 20W50 can seriously harm an engine, though this was mentioned in the context of winter.
As an aside if anyone has an easy way to remove the black stain on the bumper and trunk cause by the burning oil that would be helpful. I tried diluted Dawn and that didn't work as well as diluted Simply Green. So far the only thing that has worked is Turtle Wax Scratch and Swirl remover with an applicator pad. It works but it is not the most effective or efficient.
