I put Lucas in a hemi once and it made the engine noisy.I drained it all out and never used it again.An oilman told me that motor oils contain stabilizers.And adding more to their balanced mix just wasn't necessary,and only messed up the proper additive package balance.And because of each brand having different detergents,to not mix brands of oil in the same engine.To get the best benefit.I can agree with this, If anyone doesn't,it matters not to me.I do me,you do you! Lol
Had something similar with royal purple

Ever watch the video of what happens when you replace the oil with 5 quarts of WD40? You'll be surprised.

There's a guy on u tube his name is Uncle Tony he does a good job at discussing Lucas oil stabilizer and other additives. I used to run a quart in my truck when it sat for a long time between drives. Thats what Lucas is good for it sticks to surfaces. It doesn't flow well. It makes a good assembly lube.

@Frankenchevy What good or bad with Lucus? There is a lot of snake oil out there
Not needed. It'll gum it up. Oil needs to splash and flow inside the engine. It doesn't need to cling to everything, it already clings to everything without the Lucas oil treatment.

Yep, that's one I've seen. He mentions the display to draw you in to buying the additive. I saw the display at various stores and almost bought some but never did. I never saw a reason for the oil to do what it did in the display. A manual transmission, maybe, but not an engine.

3000. That's about the mileage my oil starts getting a little too black for me.
agree, that's my gauge instead of mileage. I'll sea foam it sometimes to see if it will help it last longer.

Usually a good indicator for not fresh engines. All the hydrocarbons and what not leaking past the rings. I just seafoam in my gas usually. Every once in a great while I'll run in the engine just before an oil change.

Probably valvetrain. Adjust the valves
