Lucas Oil Additive & a Fresh Motor????????

[PaulK]

Lucas makes good products, but I don't know if it contains zinc (ZDDP). If your engine has a flat tappet cam, then I would use Rotella-T or Delo 400 15W-40 diesel oil. These are inexpensive and have 1200 ppm zinc which is required for flat tappet cams.

Diesel or race oils are not the answer for old flat- tappet motors.

Diesel Oil

Racing Oil

I distribute ZDDPlus and use it exclusively in all of my flat-tappet motors. If you are in need, I offer a SYC member discount that will get the product to you at a savings. I can be contacted via P.M. or e-mail at <u> <font color="blue">[email protected]</font> </u> .

Here we again about the oil and Rotella in general. Now, Rotella was all right to use for awhile in the older, flat tappet engines, but it too, now has the reduced zinc levels in it. It's time to shy away from it. That Brad-Penn oil, although I've never personally used it, is supposed to be excellent and I've heard nothing but good things about it. The dino-based Valvoline Racing oil 20W-50 has the zinc content in it also. My current, personal favorite is the synthetic Mobil 1 15W-50 sold at every Wal-Mart at $22.00 for a 5-quart container. Check out Mobil 1's web site and you'll see it's formulated with the zinc, etc. for older engines. Now there's a couple different Mobil 15W-50's, so make sure you get the correct one. It's priced great! I'm sure everybody already knows the procedure for seating rings with standard oil at break-in and then switching to synthetic. As far as additives, I like one of the zinc/break-in additives at first but nothing after that. Most petroleum engineers cringe at the thought of adding things to their finely developed products.

The oil question and debate never ends does it?

I ordered some ZDDPLUS from Rich(lzdick)..sounds like a good product...fast delivery and very to deal with.....

IS the ZDDP good to use with all older engines. I run %50 leaded 110 in my cars but would like to know if this stuff is worth it. do only flat tappet cars see the benefit?
it will be going in original-
Pontiac RA III and IV 400s

Johnny Horsepower,
I run the same fuel in several of my cars and ZDDPlus is in everything of mine that has flat-tappets. It is not needed (a waste of $$) in an engine with roller lifters and/or catalytic converter (damages it). It is made for older motors to compliment the technology of current oils with the ZDDP content of oils sold pre-1989, API grade 'SF' oils. Each 4 oz. bottle contain 0.18% zinc and 0.13% phosphorus...which should be added during your normal 5-quart oil change.
