Greased Lightning, Legit or...
 

big lots has greased lightning oil additive for $5. anyone used it? is it legit or just a waste of money?

I love Big Lots (They know me by first name when I walk into my local Big Lots) , but if there is an automotiive additive there its probably because it didn't sell. If it didn't sell its probably because it didn't work.

Personally, I wouldn't use an oil additive for a modern oil. Simply choose the correct weight oil for the car and the desired results. Most supplements are either thickeners or cleaners. Use the correct weight and keep your oil changed and you don't need to spend money on either.
