Getting ready to fire up our 360. It's an 85 engine we did with new pistons, new flat tappet hydraulic cam. My question is the oil my brother put in is a diesel oil rated SL. I noticed after he poured it in the engine, that it is a synthetic blend. I used the Mopar cam assembly lube, which they tell me is great stuff. Should I have reason to worry about wiping the cam with this synthetic blend oil?

Personally I wouldnt use a syn blend oil on breakin.

Alot of guys do it without issues, but....

Id use Rotella and a bottle of Comp Cams or similar additive.

I go a little over board with my cam break ins. A local machine shop has oil that they had a local refinery formulate for them. It is chock full of zinc. I use their oil, and 2 bottles of SLOB.

Dumping the oil and saving it for something else will be a lot cheaper than rebuilding the engine.

Any oil with ZPPD there are only four. Joe Gibbs or Valvoline are the most common.

synthetic is a no no for breakin unless the fact that it is a diesel syn and or a part syn blend makes it OK to use for breakin but I'd be doubtful but I'm not an oil guy & am going by what I know so far. I'd drain it & go with a proven performer like Bradd Penn & other proven brands. You've went to far to take a risk now & after it's broken in & running strong you will have forgotten about the little bit of extra time/money it took to rectify this

it's my understanding that diesel oils have the right amount of zinc in them. since i don't know that to be 100% true with a synthetic blend oil i would just get 2 bottles of Lucas breakin additive and one to the break in oil and the other after you change it. most auto parts stores have Lucas.

Bradd Penn




Cept Penn is a semisyn...

I called Total Seal and they told me no syn or semisyn for at least 800 miles..so

Plenty of race motors come out of the box with Penn.

I was talking to a local machinist the other day he uses Mobil full syn on the skirts, rings when putting motors together..

So, flip, IDK. Id still play it safe and go with a full dino oil...

As far as the diesel oil, they or may not have enough zinc...If you have moderate to high spring pressure, probably not. Id still add a bottle of Comp, EOS, etc.

I know nothing about the Lucas break in oil. Id like to see a lab report on it. If its like the rest of the Lucas stuff...run...

EDIT. Found some info on the Lucas break in oil, looks to be good stuff.

No zinc in any of the deisel oils since they put the cats on them since the zinc plugs them up.

What is your definition of "No zinc"


I just looked at some recent VOAs, DelVac, Rotella, Napa 15-40 all show over 1200ppm of Zinc. Not what I would call "No zinc"

The stuff doesnt have 1600 or so like it did 5 years ago, but considerably better than a SL-SN oil...

But since you now know that oil needs zinc (zddp)for flat-tappet cams, especially during the initial break-in, keep in mind you can have too much in the oil too...so don't go overboard adding excess oil supplements to get the zinc levels up there. Too much zinc can be equally harmful.

Most decent speed shops will stock a zinc (ZDDP) additive that specifies how much should be mixed w/ what types/amount of oil....whether it is GM EOS or something similar.

I'd drain the oil, run a heavier wt diesel oil w/ the a ZDDP additive...makeing sure to prime it good and quickly before initial start up. Good luck!

You guys are deep into the More's Better theory.

You know, if some is good, more's better and too much is just right!

At least take the time to read the Joe Gibbs literature on Diesel oils. His point is, the extremely high detergent levels in the oil for diesel engines makes it harder for the ZDDP molecules to find a place to stick to. So you can have all the ZDDP in the world but if it can't find a surface, it doesn't do a lot of good.
Several years ago on this board a member detailed an experience with Diesel oils and lubrication failure on a new extremely high output engine. Most pooh-poohed the story, but he had no reason to lie about it. Maybe there is a hidden weakness in the Diesel formulations.

I think that the "use Diesel oil" theory is an article of faith among the believers and expect that its believers cling to the idea out of a religios fervor. Maybe it's time to open our eyes.

Do yourself a favor and get some Brad Penn break in and be done with it. It works, has a crude oil base stock, and will not be any problem whatsoever being a semi synthetic. You dont NEED a dino oil to break an engine in...the internet can be a dangerous place....
