Any 10w-30 HDEO users?

Duron 10w30, and PC just rolled out a synthetic offering. 91-12.3-3.6
last change in my wife's accent and daughters mkx I used Duron shp 10w30 which is a blend .
I think this is the best the accent has ever ran its a normally a noisy enough engine seems to be much less mechanical noises But maybe that's just me ?
As for the 3.7 in the Lincoln I swear you could almost run water in this it never seems to vary no matter the oil used .
had the same same results in a 2012 mustang 3.7 one of the better engines I have had.
 
I've run various 10w30 oils in my 2017 Ram 3500 since it's first change at 24,000km.

Consequently, whatever was left over went into my quad or other ope other than my snowblower.
 
Tried 10w30 Rotella T4 in my Chevy 350 flat tappet cam engine. The Rotella had better hot oil pressure at idle than the current Valvoline 10w30 VR1 I have in it now.

The cam still has all of it's lobes so I guess both oils are working. 10 psi hot with the VR1 does not install confidence. Pressure was closer to 20 psi with the Rotella.

I may go back to the Rotella next oil change.
 
I use Mystik 10w30 HDEO in my OPE and our 2005 Jeep GC. It’s got >200k on it so it won’t be the oil that gets it.
 
Delo XLE and VPB 10w30 have both been in the Impreza at various points. Impreza is getting all the oil I’ve acquired over the years just as a cost-savings measure since the newer vehicles all get HPL.
 
I did but in a gas car asking for 5w30 instead, nothing wrong with that except each jug is only 1 gal instead of 5 qts. When on sale it is still a good deal so per qt price is still good.

Why 10w30 rather than 15w40? Other than the cold, Iassume you dont live in a cold always climate. I run 15w40 in NC, but have thought on 10w30.
If you look at his sig he is in Indiana and it gets cold there just like where I am at. PA gets cold too
