More wisdom. Thanks.It’s garbage for my application. I would definitely run PUP 5w-30 in my civic calling for 0w-20. There’s plenty of information out there saying it barely makes the cut as a 30 weight anyways. Now in my car when I press the gas and the turbo starts spinning, you know something is about to shear out of spec. I’d much rather have a 40 weight in there than the 20 weight PUP masquerading as a 30 weight.
SOPUS uses a rubber gasket in the top of the cap which seems to make a better seal than the cellulose gasket you find in the top of the 5qt Exxon-Mobil and Castrol bottles, so they don't need the foil seal I kinda like the idea because I find the foil seals to be kind of annoying cause they're usually really well adhered to the bottle and you can't just remove the whole seal so you have to cut it and sometimes there's residual foil in the way that interferes with pouring, although I find the rubber seals on the SOPUS bottles seal a little too well and with the low profile small caps they use they're kind hard to get off everytime you reopen the bottle. Ideally I'd like a bottle with the wide opening like Mobil1 and castrol jugs with an easy pull off seal like they use on chevron jugs.I also liked the notion of silver lid under the jug cover. Pennzoil cheeps out and sell the jug with no silver lid.
That M1 is significantly thicker than PUP 5W30 ILSAC.I used to believe the same, but this M1 seems as quiet as the Pennzoil, fresh to fresh
There is no 5w40 PUP!That M1 is significantly thicker than PUP 5W30 ILSAC.
Comparison should be done with similar oil, like Catsrol 0W40, PUP 5W40.
That being said, I could always notice M1 being noisier in my 2.0T VW's. Few weeks ago I switched from PUP 5W40 to M1 0W40 in my BMW and did not notice any difference, but then engines do not get any smoother than BMW inline six, so who knows.
