Hello all,
Just wanted to know how many of you use the Lucas additives with your
oil.
I just tried some in my personal vehicle 2003 HD F-150 Supercharged. I noticed that the stuff is pretty thick. However, I noticed when idling in gear my vacuum is normally at 18 sq. in.
After adding the Lucas additive I noticed that the vacuum is up to 21 sq in. at idle in gear.
Seems like this stuff is pretty good
