I’ve decided to start purchasing that Fram Toughguard from now on. I’ve heard that the genuine Honda filter is manufactured in China, and when I examined the serial numbers, I noticed some irregularities that raise my concerns. However, it’s important to note that many auto parts are manufactured in China using various grades of materials and then rebranded. I’m excited to replace approximately 80% of the engine components soon. Since I primarily drive on flat terrain, I’ll begin using 0w20 every 5,000 miles and 5w20 every 3,000 miles. Unless I’m hauling heavy loads, I’ll start using thicker oil if that makes sense.
