does redline oil contain zddp?

[Twister]

So would it be beneficial to switch to using that oil?

Where would one have to go to get the good stuff, full of the additives? Do auto parts stores carry the off-road only oils, or..?

Diesel oil in general also has added benefits for cleaning the inside of the engine. Diesels run much dirtier, even the new ULSD rated ones, therefore the oil has to do a better job of cleaning the engine to keep things from coking up inside.

I just recently switched to Motorcraft 10W-30 CJ-4 spec diesel oil. It comes out MUCH dirtier than the stuff that I used to use, meaning that it's taking/keeping more crap off the insides of my engine. Can't wait to tear into this engine in a month or so and see what she looks like inside.

i searched and none of the chain parts stores here had what i needed. but redline offers a break in oil that has all of the zddp that will do 2 oil changes. i bought 2 bottles. 1/2 of a bottle will do up to 6qts. that is actually what caused me to ask the rep "if redline makes an additive to add zddp to their oil......obviously their oil doesn't have it"

the machine shop i use sells it, and royal purple dealers can get that purple-goop that sucks but still has the "off-road only" labeling

If your engine has roller lifters then regular new oil will be fine.
Diesel-spec oil has more ZDDP in it. I would use it in a flat tappet engine. If you look for a while you can find Rotella in 10w-30. Seen it occasionally at Wal-Mart.
The high-mileage oils will have a little more ZDDP than regular oil but not as much as diesel oil. Look on the oil company websites for the MSDS and it will tell you.
For a while STP was making a ZDDP additive called STP Oil Conditioner or some such (this is NOT regular STP) but I don't see it on their website any more.

I have no idea wtf Im talking about here, but I read something somewhere while learning what tappet lifters are and zddp and stuff...
It made mention of break-in conditioners for use in new engines... Said adding that to your oil will do the trick. No idea where to buy this stuff though.
Anyone know wtf Im talking about? 'cause I dont.

on a microscopic level steel is porous, those metals fill in the pores providing a smoother surface for metal-to-metal contact, also making for more even wear. both of which is necesarry for flat-tappet camshafts among the numerous other metal-on-metal parts of an engine

I actually had Tourist Transmission recommend to me years ago to use 15W-40 in my T5 trans. I guess maybe this is why? I used it, and it's worked awesome. I'm putting it back in after it's built. I got 18X,XXX miles out of the original trans.

I know Royal Purple motor oils are rate with an API SL (the older standard). New motor oils that are now on the shelf have an API SM (the new standard). The new rating could have been the Zinc (ZDDP) change. But from an oil anylsis that I have done with Royal Purple, there is at least 900 to 1200 ppm of zinc.

SM is superceded... SN is the latest for SPARK IGNITED engines.

What ever happened to 'Read the labels'?? Everything has an ingredients listing as to what is in a product. I never buy anything that does not list what a product contains. This is how a lot of law suits are filed because some manufacturer may not state what is in their product....It is the law that they have to list what is in the product.

the info in question does not appear on any oil label

from an oil anylsis that I have done with Royal Purple, there is at least 900 to 1200 ppm of zinc.

i have no idea what to compare that to.......is that an acceptable level? also when was this test performed? as royal purple does submit their oils to the API and therefore would be subject to their regulations

Ok here's the deal.

All API certified oils, SM and after, have reduced levels of ZDDP. Redline's oils are not API certified, therefore are not subject to these limits. Note that on the bottle they say "Recommended for API (whatever)."

A search on bobistheoilguy.com will show that Redline's oils contain more than enough ZDDP for a flat tappet engine. For example:

Generally you want at least 1000ppm zinc and phosphorus for a flat tappet cam engine.

Ideally, a 1000ppm for zinc (zddp) is what you want. I think the new zinc level is 500ppm.

A higher API service label does not always superced the previous one. It may work for those with new engine desgined for it. But for us old vehicle driver, it could spell bad news.

Summit Racing. You're referring to camshaft break-in lube. They also have "racing oils" that are labeled "for off-highway use only", nudge nudge, wink wink.
Pricey stuff though. I'd just use Redline, high-mileage oil, or diesel oil. Rotella Synthetic 5w-40 would be good stuff and a little thinner than 15w (good) and only costs $16 a gallon last I looked.

Glad you mentioned something amongst the lines of "recommended for API".

Amsoil is a HUGE example of many oils that are NOT certified by API, yet they still try to advertise around that as much as possible. They like to note they are the first API "rated", but NOT API certified... Big difference!

the ONLY oils certified for SPARK IGNITED engines from amsoil are their XL and OE lines of oil. Their ONLY diesel oil certified by the API is their "PCO" oil, which is only a synthetic BLEND.
