Have a 2015 Tacoma with about 30k miles on it. I've always run Mobil-1 5W-30. But this past winter I noticed it seemed noisy, and I switched to PUP 5W30. My mileage went from around 21 to 19 or so. The drop is pretty consistent. Doesn't seem any quieter, either.
Anyone else experience a drop? Does better mileage mean more "slippery", and hence, better lubrication?
I'll probably switch back to Mobil-1 this summer.
