Exactly.It a roller cam. No sliding wear - until the tappet bearings give up the ghost. Then NO OIL formulation can save it.

Ouch. I got all my jugs with the $5 rebate earlier this year so the jugs were only $17 with rebate. wewGrabbed a 5qt jug from WM and a quart. $44.

It certainly wouldn't hurt. Try that and go up a viscosity grade from recommended is all you can do. If it's a mechanical failure due to bad metallurgy and/or design, all you might be able to do is extend the time to failure, but it probably won't prevent a failure.Going out on a limb here, but wouldn’t an oil with Ti (only Castrol at this point and has both moly and Ti) be of benefit here especially with the Hemi camshaft? If most engine wear occurs at start up/warm up and titanium activates at a lower temp than moly, your getting that additional wear protection earlier and then the moly is also there as the oil heats up.
I am in two vehicles.So who is running Valvoline EP?

That would be a bad design. Checking my Accent's live data with the Snap On scan tool we have at work shows all variable valve timing values right where it's supposed to be even with 15w-50. This stuff is computer controlled and many modern ECUs are capable of running closed loop within seconds after a cold start, which obviously requires proper valve timing advance/retard for the given situation, even with freezing cold thick oil.I would think the 0w-40 would trigger the check engine light due to the thicker viscosity.
I’ve seen it before on the hemi ram’s
I’ve been told some are sensitive to it and some are not.
SameI sent off a sample of 0w-20 with 5000 miles for a uoa with tbn, still waiting on results.
Yes it would be and there is no technical reason for that to happen. What has been seen is that some ECM will monitor the VVT actuators to detect a signature of a higher viscosity oil, this is a nanny system to enforce the CAFE award provisions.That would be a bad design.

Anyone's guess lol.Similar or better than this?
0w20>>> 2018 Jaguar XF 2.0So who is running Valvoline EP?
A nanny system? Why, once the manufacturer recommends a lighter weight oil, would the manufacturer be responsible to enforce the user to use it? Haven’t they held up their end of the bargain in CAFE regulations? They built an engine designed to handle a 0w16/0w20 oil, to manage an extra 1 mpg of fuel savings. Isn’t that all they’d be required to do?Yes it would be and there is no technical reason for that to happen.
