Lucas isn't going to hurt anything, but it isn't going to help anything either, All it does is bring the oil up a grade while diluting the add pack. With that being said, you deserve better than this crap man, let her boyfriend deal with this.

They will throw a notifier code (P1521) based on oil pressure relative to oil temp on anything other than 5w20. This will not set a check engine light. I've run 0w40 and up to 15w50 in 5.7ls both eagle and pre eagle without issue. They will be happy with pretty much anything you put in there...

Mobil 1 0W40 would be an excellent choice if out of warranty. The 392 specs 0W40, and has identical clearances. The Mobil 0w40 was the original SRT oil before the switch to pennzoil.

The dark color is visibly suspended particles in clean oil on the dipstick. The oil temp never went over 215.

Not yet.. I will soon.

Replaced the rod and piston on the affected cylinder. (new). Both heads were replaced, the rockers were soaked in marvel mystery oil for a couple weeks, and the pan was cleaned very well, anything remaining would have been under the front cover or on the pistons, there wasn't much sludge on the...

Id expect it has at least 450k equivalent. The lack of an hour meter on a police package car on these is definitely silly.

No idea. Likely thousands. It belonged to 2 agencies and was retired at 156k.

I did have a combination of mobil 1 0w40, rotella, pennzoil platinum, valvoline maxlife and whatever other half full bottles I had lying around for the engines first after repair change as a flush, although it probably was in the crank case for less than 100 miles, so this wasnt the first change...

180k. Oil in it had chunks of sludge. Rod bearing I pulled changing the piston was immaculate with the original machining marks still present. Replaced on the bad piston of course.

Looked like any other oil. Light amber golden. It honestly doesn’t look like the oil itself it’s dark, but the stuff suspended in it is.

Yep, gonna change it tomorrow and cut it open for this thread.

So this car I got with a dropped valve seat. Ex cop car. Changed the heads and bad piston, wasn’t the cleanest, had some sludge and lots of deposits on the bad piston as well as the bottom of the others. Decided to give the new valvoline oil a go (5w20) and this is what the oil on the dipstick...

Most base oils, even Grp II oils, are completely clear, so the pennzoil crystal clear claim is pretty baseless. The additive package is usually a dark brown, copperish color which gives the oil it's golden color when dispersed. Difference is additive package levels, type, etc can all affect color.

We're all oil sniffing weirdos :D
