03143C Edge High Mileage 5W-20 Advanced Full Synthetic Motor Oil, 5 Quart

I purchased a car that had run 32000 mile only. I drove another 40000 miles with TOTAL quartz 9000 but P0420 code never get dismissed. I tried so many product like engine flush, injector cleaner, valve cleaner, Oil saver, cataclean, catalytic system cleaner, 98 octane petrol. Nothing happened seriously.( P0420 has gone due to 98 octane petrol but coming immediately under harsh acceleration and remained for 2 to 3 months). But right after 200 miles on castrol high mileage oil 5w20 oil. The code has gone and not coming back at all. Amazing!!!. Add to above I received 2.5% more gas mpg compared with TOTAL oil

I give it a five star because it’s engine oil and it works in my car, but my five-star rating doesn’t mean I’m an engine oil expert or that this oil is better than any other oil brand. I have previously been told that the best engine oil brand is ANSOIL, which if going by its price, it must be a superior oil. As I was told, ANSOIL doesn’t have any wax substances, which, supposedly, can be problematic for some engines. Anyways, I purchased this oil for four main reasons; it’s synthetic and superior to most petroleum-based oil. I can get it a lower price here at Amazon than on any other local store. It arrives at my home free of shipping charges…well somewhat free since I must pay for my Prime subscription…I guess nothing is really free. But the main reason is because I had changed the oil on my 2013 Mazda CX9 a few weeks before and then realized I had used the wrong oil specifications. The 2013 Mazda CX9 calls for 5W-20 oil and I had used 10W-20 instead. Must mechanics I consulted with said it wasn’t a big deal, while online forums were not cleared about the subject. I didn’t think it was going to cause problems either but wasn’t completely sure. So, I reasoned, it’s my car, I’ve been taking good care of it and it looks and run like new. So, I had to decide on whether to spend another $24.67 and have a piece of mind or not replaced the oil and ran into many sleepless nights wondering if not changing the oil was the right choice. So, I replaced it, I’m short of $24.67, but having piece of mind is priceless. By the way, I’ve been using Castrol oil on my cars, for the most part, since I purchased a new 1986 Dodge Daytona…it was a nice looking car, but poorly made.
