Why is this? I’ve noticed this on my cars at times, too. I generally stick to Mobil HM but occasionally throw in some Penzoil HM. When I do, I need to top off at around 1,500 miles. Then good for remaining 3,500
OP: I’m at 208,000 on my 05 Accord. At 150k or so, went from 0w-20 to a HM grade. If it were me, I’d stick with whatever you’ve been doing. If it were me...
