Oil Talk..found this

I "broke in" my own C/R cam ran it for an hour at 1800/2200 rpm.
Changed the oil, ran another hour under 4000 rpm changed the oil.

I did do an oil analysis on both oil changes and do one everytime
the oil is changed. Only because it's a "perk at work".

Wow, who would have though the ability to turn a wheel and push some pedals wouldn't qualify you as a petroleum engineer or a mechanic.

Don't know if the CR break in does much, but it sure is nice not to worry about that first start. I'm going to attempt to break mine in as if I need to with break in additive too just to be sure.

How long is everyone running that first batch of oil?

I'm going to take it down to the ramp for the break in. Wasn'nt planning on taking it off the trailer, just wanted to make sure I had plenty of cooling water. I would like to go for a spin if I don't need to take it back to the house and change the oil.

+1 Gary, the guy's would know their own product

How about a thread on anatomy? Regarding barefooting, of course.

I merely pointed out that in her original post what she said was true in regards to automotive applications(in particular the penzoil comment and the 10-40 weight comment) in an attempt to clarify what she was reading on the other forum. If anything I was pointing out that that rat guy was infact copy and pasting automotive results and incorrectly applying/inferring them into marine flat tappet applications. I'm sure you have tons more marine experience than I do, but that wasn't ever in question. Take a chill pill and stop being a douche for no reason.

Sorry to have jacked you up......But your knowledge of high rev, high heat buzz bombs has little to do with the marine standards that dictate a high level of ZDDP. This was not a put down on you , nor your expertise, just saying compare apples to apples and nothing more. Also the cut and paste was not a slam on you,

This is the snake oil part - the oil manufacturers design a balanced product - When you add the extra stuff, the oil is off balance.

I drank the kool aid & use the high ZDDP stuff too.

Seems like cheap insurance.

[QUOTE=jbach] ^^ unless we know what kind of oil was ran and change intervals and... and... it just looks like a worn out tappet to me.

QUOTE] I do not see a worn out lifter......I see oil failure
That is a prime example of oil failure, first you wipe out the lobe, then the lifter will soon fail also.... ZDDP is a amazing additive.

lol-just kidding ..... 500 hundred hours 1 season? Are you year around then?

Ah, 500 hours. I'll have that beat this year, easily.

Moonshiner? I have far too many teeth.

FWIW, i run rotella T 5w-40 synthetic. i used a zddp additive last change. do you think it's necessary? here is a virgin oil analysis of it.

Doc’s got it

Oil weight isn’t a big deal.
The big deal IS flat tappet cams.
The cam is cast (soft metal) then SURFACE hardened .010 in (ish)
The valve spring MAINTAINS pressure on the tappet/cam
surfaces of 50 / 200 psi when the valve is closed/open
ZDDP / phosphorous is a high pressure additive that
Is needed so the cam doesn’t wear through the THIN
surface hardening .

Clear as mud now?

Sorry dude, not looking for mice. But I am willing to share a bit of my marine knowledge with anyone. If you are offended by my posting,SORRY....
There are a few of us here that have seen the results of "modern oils" in flat tappet motors, if you choose to learn on your motor , so be it, but there is a kinder softer way ...

There is such a thing as too much info.
