Today, I finally changed my oil for the first time in a long time. I can't remember exactly when I last changed it, but it was in the ballpark of March - May 2021. The oil and filter before was Penzoil's Ultra Platinum and the M1-110A filter from Mobil 1.
I have ZERO excuses for why I didn't change it sooner, perhaps it was the bold claims about synthetic oil rigidity, or the 25,000 km lifespan claim of the filter (or laziness). This is the first time, I have gone and entire year without changing the oil in my car and boy do I regret it. Please send your condolences, as I may have just witnessed the beginning of the end of my engine 😅
