How much of this stuff, http://www.hardwarestore.com/media/p...9_front200.jpg, should I put into my 7 quart oil pan for start up/ initial break-in?? The bottle I got is 1 quart, should I dump the entire bottle in (1 quart) and use 6 quarts of oil? This is the only oil stabilizer product avaliable in any of the parts places around here, I was told it is good for cam break in due to its ZDDP ppm count.

Read this carefully and then make a decision.

I have read that, I have also heard good things about it too. How much do you recommend I use if I decide to put it in??

[Jmark]

I have no idea. Doesn't the bottle give that info?

[DeathRattle]

The bottle says use the whole bottle...I would just use one oil that is made for break in...brad penn makes it..

normally you would add 1 qt for a V8. That said, I don't trust the lucas addative. I use 1 bottle of STP oil treatment per oil change.

I would not use that cr@#, or STP in a lawn mower.

I don't use STP in my lawn mower.. just high detergent 30W and change it every year...

IDK.. I used STP in my '65 Rambler, that has a 196 solid lifter engine, and the lifters are quieter with it.. I don't like the fact that it is super thick, but it seems to mix well and does not end up thick..

That is because the lifter, or valve guides are worn out and the STP has increased the viscosity of the oil so much that it has masked the noise. FWIW, higher viscosity oil does not flow to vital engine areas as well as a lower viscosity oil, especially in a cold weather startup situation.

I drove a 69 Z/28 with a solid lift 302 and when the valves were set properly that noise was literally music to my ears.

I apologize, I am just a little passionate about these snake oil engine additives were are convinced we need.

I understand.... The valves on my 196 still sound like solid lifters, but they are a little quieter. I only use the STP for the camshafts, because of the ZZDP. I know it's not the right amount of it but it's what I can get easy enough. The 196 is worn out and smokes a lot. I did put a bottle of no smoke in it, which didn't help much. Will be eventully replaced with a 302/AOD but for now, it's my daily driver

GM still makes their EOS. Probably the same as the old, but they changed part #s and raised the price.

I would vote for 0 you may need to look for a virgin oil analysis. Last time I checked it seems like it had no zddp.

I agree with the others, forget the additives. For initial startup/break-in run normal oil. After cam break-in change the oil and filter. Then run normal oil for the next thousand or so miles. Then consider a fully synthetic oil.

Modern oils have really complex chemistry. They're optimized from the refinery. A top quality oil, especially synthetic, should have no need for additives.

Except at flat tappet cam break in time. Not enough EP additive (ZDDP). I agree with MI2600, the GM EOS is a good break in additive.
