Lead is not good. I think this engine has a bearing issue.

I don't think the thicker visc would be a concern... I run E85 so I expect it to shear down a bit. The Scatpacks and hellcats spec 0w40, and they have identical lower end clearances.

Just a little update. Decided to pull a couple spark plugs and borescope it... cylinder walls looked great, original crosshatch present.... what I did see was evidence of valve seal seepage with gummy deposits on the edge of the piston and top of the cyl.... I'd wager it's very possible for some...

I'll send it out soon and post on this thread. Going to do a 3K mile run on the valvoline, if iron drops significantly, we likely know there is not a major engine issue going on. I'll then do another run of M1 0w40 and see how it looks. I do think the cleaning theory is correct here.

Filter is already gone sadly .... wish I would have kept it or thought of it... 🙃 stress kills the brain. I guess cleaning old deposits is possible, I replaced the valve cover gaskets 50k miles ago and there was almost no varnish. Who's to say around the pistons though. Surprisingly, the...

It could have just been a particle streak or something. Who knows. I'm not worried about it unless the coming interval also shows increased FE.

Affirm.

Changed oil this morning with valvoline advanced 5w30. Sampling in 3k.

C Previous was Valvoline, the ones before that were shaeffers 9000

Comp 274 on the horizon if so!

Completely normal.

FYI... this is the new 0w40 reformulation.

Latest report came back .... decided to give M1 FS 0w40 a shot.. Engine was run pretty much the same as before. Will be going back to valvoline next OCI.

New M1 0w40 Euro PDS shows it meeting API SP and the pour point was raised from -67 to -42......... Really hope they didn't cut the zinc/calcium much but that seems likely given the SP cert... Also makes me wonder if this is something upcoming related to stallantis since this oil was basically...

Run it with confidence. It has 940ppm of zinc and ~300 of moly, one of the better add packs off from off the shelf oil..

It was indeed 5w30.

5W30 was the weight used. BS made a mistake.

haha.... my shop is there but I spend most of my time outside of that area if at all possible..

Tuned and running around a 4.6 sec 0-60 time. E85 used as the only fuel for the run.. Run HARD… it sees 6000 rpm every day.. Little disappointed it sheared to a 5w20 but probably to be expected on e85. Add pack looks great on this valvoline!

The zinc and moly in that valvoline! 😮
