Thinking of substitute one quart of oil with Lucas good idea or not

 

You're kidding right?

 

sounds like a bad idea according to stiggy. Maybe one for the tech forum too.

 

DON'T DO IT!!!
I tried it once in my Heritage (1/2 quart on an oil change, about 10%).
After a nice run of about 30 miles, I pulled the dipstick while it was idling and the oil was FULL of little bubbles, not foamy, just lots of little bubbles in the oil.
Now I'm no expert, but bubbles in your oil can't be good.

 

If you're not having any problems, why??

Don't fix what ain't broke!!!!!
