Lucas Engine Break-In Oil Additive...

Getting ready to put my engine back together and was thinking of using the Lucas Engine Break-In Oil Additive with zinc to wipe the cylinder walls down before installing the pistons. Good idea/bad idea? I have assembly lube for the bearings and such, just looking at this instead of 30 weight oil for the cylinder walls.

Thanks for any help!

just regular mineral oil is fine for the cylinder walls you don't need that stuff for that.

If you're running a Flat tappet cam then its a good idea to use it.

Didn't know if the zinc would help out on the rings or not, and it's a solid roller, so looks like I'll just put it on the shelf.

Thanks

I just dip my pistons in the oil that will be run in it afterwards and go. If everything is right,the rings will seat after a couple of good burnouts.

Sounds like as good a plan as any

Everyone has their own method, but I just spray a very light spot of WD-40 in each cylinder before installing that piston and wipe it with my hand. Basically, you're just putting a light coat on for the skirts for initial start-up. I never put oil on the rings themselves. I told a guy here about this method, and he "said" when he started doing it this way, it showed a faster ring seat on his dyno compared to oiling the rings... Myself, I've never actually seen this, but an old timer told me this back when I was in high school, and at the time he was the "guru" in these parts, and I've never had seating issues...
