New QSUD spec sheet

[Lex94]

Don't know about low VII in QSUD 10w30. I would use A3/B4 Mobil 1 High Mileage 10w30.

Would you know the noack for qsud 5w30.
My sis chevy equinox needs a good low noack 5w30.

Thanks

Any 10w-30 is going to have lower noack than a 5w-30

Penzoil platinum, Mobil 1, Valvoline, etc. maxlife 10w-30, Mobil 1 HM 10w-30, QS, Castrol.

10w-30 good

Yes but sis 2016 chevy is under warranty.
Got to go with the yucky 5w30 till then

Wonder if anyone for warranty purposes could tell if you mix 10w30 with 5w20 dexos 1 to keep noack and vii low

Don't bother.

The QS line has traditionally shown decent Noack numbers for an ILSAC lube, at least through the last few years.
