Default Does anyone use or recommend using ZDDPlus?

I think I am going to join the Bob is the oil guy website. I have too many oil related questions which need answers.

I am interested in knowing if anyone is buying ZDDPlus in the 4 oz bottle and adding it to their oil. It does not seem like a bad idea considering what I have read. I realize ZDDP is bad for catalytic convertors so I do not want to talk about that, but rather it's effect on engine protection.

What I want to know is if adding a bottle of ZDDplus to my oil will increase ZDDP levels, thus offering better protection for my engine.

I have not used it and have over 100,000 on my engine via my right foot. If you are planning on keeping your car for 900,000 miles, I'd research it. If not, research mitochondrial DNA or something worthwhile as nothing in a bottle is as good as consistent oil changes.

I posted this in another thread.

Don't see any reason for us to be runing it.
Don't have flat tappet cams.

Alot of the buick guys use ZDDPlus, but then again GN's have flat tappet cams.

That's an interesting article. I read about basically the same thing a few years ago. I always knew rotella was good oil. I am gonna do a search and see if I can't find out how much ZDDP is in the current Rotella. Does any one run dino rotella 15w-40 in their WRX?

A little info is given in the link. ZDDP is good for breaking in a new engine. Perhaps a little bit over the concentration in the new "improved" catalyst friendlier oils, may be OK for very severe service.

http://ezinearticles.com/?Why-the-Fu...DP?&id=2090427

For me, even M1 5w-30 works, even though it's a low friction, short life synthetic oil, but I use other additives with it; not ZDDP. It's my long term experiment beginning in 2001. So far so good, against other turbo engines falling by the wayside despite better oils and longer change intervals. One case never proves anything within a complex situtation. I have even seen Amsoil fail on an extreme change interval reported in the Nasioc files.

Ultra high molecular weight, low concentration, polyisobutene/neutral base oil which is mandated under the CA GREET carbon dioxide reduction program for diesel fuel. Along with Torco MMT in 93 octane pump gas.

Up to 8% of the manganese oxide ends up in the motor oil. In that sense it is a dilute oil additive. It is known to be an effective oil spill absorbant it that field of application. I am beginning to think that is not necessarily bad. Most of the rest goes out the exhaust, and that doesn't seem to be bad as indicated in the early MMT tests conducted at SWRI on catalyst and oxygen sensor life.

The polymer works through non-linear kinetic effects. This is complex rheological and combustion science.

The Torco is there so I can always stay away from detonation with a spritely tune. According to the Torco blending chart, it is a bit over 96 octane.

so...in laymans terms

it is an almost certanty that you havent blown it up using m1 oil is that you dont get any detonation, by using FUEL additives, that pounds the bearings to **** and causes spun bearing failure

And THAT is the REAL issue

I think so too. Detonation is much worse than any oil is good.

The recent destruction of an 05 na Legacy engine (one daughter's anniversary edition) doesn't seem to fit the pattern about detonation though. It wasn't on synthetic oil either, much less M1.

In the na 05 automatic transmission Legacy case, M1 5w-30 cannot be blamed; it was done routinely at a shop, according to the Subaru specifications in the owner's manual. Perhaps no oil is much worse than detonation is much worse than any oil is good.

Meanwhile, I just keep on rollin along., keepin my eye on the ball.
