I know this topic has been discussed on here several times. I searched, found and read them. Someone did some great research and foudn the zinc content of all the brands but it was in 2006 or early 2007 and supposedly there has been legislation p***ed since then that affected the amounts. I went out to find some EOS from GM and no luck. No one has the old or new formulas. I saw some stuff in a purple bottle at napa but can't remember the name. It said something about PTFE formula and blah blah.. anyone know what I am talking about? it is similar to EOS? The engine is new and I want to take this thing to roundup, but no trash it. I put in cheap oil for break-in, and the cam-break-in is done, but not the first 500 miles of driving. I found napa has sae 30 non-detergent oil specifically not recommended for modern engines. Is this a good choice? Let me know what you reccomend.
Some recent posts on here say that Eastwood sells a "zddp" additive,though I have not looked into it.
any of these useful? http://www.napaonline.com/MasterPag...rtNumber=65148&Description=Motor+Oil+Additive http://www.napaonline.com/MasterPag...rtNumber=10001&Description=Motor+Oil+Additive http://www.napaonline.com/MasterPag...09&Description=Motor+Oil+Additive+(Lubro+Moly) I think this is the one I saw http://www.napaonline.com/MasterPag...tNumber=GL3000&Description=Motor+Oil+Additive FAST ED THey ahve it at napa, is it good enough on it's own or do I still need an aditive with the diesel oil? UNKL - I tried the local dealers, they are all out of EOS. I've never bought diesel oil.. what are the letter codes and which is which? I was ***uming i'd change the oil, so what combo of oil and additive should i use?
Old school says to use non detergent oil. I haven't rebuilt an engine in some time, so not being familiar with new oils, I would suggest getting on some websites relevant to your engine and find out what they suggest. The PTFE stuff sounds like a bad idea. The reasoning for using non detergent back then was to allow the rings to seat. Detergent oil didn't work on the rings, or at least the one time I put it in a new short block. Smoked for 100 miles, then when I put the non detergent in, no more smoke, ever.
We use the additives. Don't want to stock anymore oils,too much variety. Comp# 159,Crane#99003-1. Hope this helps>>>>.
Well I wasn't sure what the ptfe thing was but I ***ume it is a detergent so nevermind on that one. I need to do this oil change today so whatever I get needs to be local. Ordering stuff is out of the question. I went and looked on the rotella site and looks like most of them have detergents. The plain rotella T doesn't say anything about detergents.. is this the one to use?
A lot depends on what you used for rebuild parts. If you used 'modern' rings, bearings, etc., its a 'modern' engine (internally). The zinc content in the oil thing is mostly for cam/lifter protection during break in and even later on if you have HEAVY valve springs. If you used a roller cam, none of that applies anyway. Kind of hard to think of a "vintage" engine being modern but lots of them end up that way because of modern technology used to make the parts we use. The machinist also has had to change hone finish, etc. The ptfe thing is Teflon content in a base oil of some kind. Not one of my favorites.
I use Shell Rotella. Even with lower zinc, I believe it still has more than car oil. Once I hit 10,000 miles, then I switch to Mobil1
PTFE is Teflon, which I think is proven to be useless in an engine. I seem to remember something about PTFE recently. Maybe someone can correct me if I'm wrong?
no my engine is not too modernized. cast rings, flat-tappet cam. It is a '75 SBC 400. I started it a couple times, fixed some problems, then did the cam break-in when I was able. The oil in it looks great still, and I was going to just add EOS, but now that I can't find it I am looking for other options before I drive this thing a lot.
Torko (spelling?) has a break in oil, Bob Wilson was telling me about it and he is using it in his bonnie car's new mill. It's supposed to be able to deal with these "new" oil issues.
G M has a new part number for E O S ***embly Lubricant. #88862586 Gr. 8.800. I recently bought it at a Chevy dealer. Hope this helps, The FOGGER
Hell, I don't understand yall!!!!!! The ZDDP is what you want, because that's what has now been almost totally removed in nearly all oils out there with an API certification, and it's because the Zinc and Phosphorus are believed to shorten the life of a ******* catalytic converter, of which few, if any, are to be found on our member's rods, the daily driver? Maybe so. From their(ZDDP) ads here link to their website, which has lots' of info. There are non API rated racing oils available also that still have a good dose of the zinc compound and they caution on the label against use with a cat conv. I know of Torco, and Amsoil (which I sell and use), and I'm sure Red Line and others have it also. Read that the new Shell Rotella has reduced the ZDDP because the newest diesel pickups have cats now, Amsoil went a different way, new oil intended for the 2007s & later, the other 3 diesel oils remain high in ZDDP and aren't to be used on the rigs with cats. So quit farting around, and order the ZDDP and be done with it. Once I saw a pix posted on a forum of a bunch of guys standing around a dead horse, beating the carc*** with sticks, might have been here, I dunno. But I wish I had saved it now! And if I had, I would paste it to my response to this thread. Dave
DIRTY OLD MAN - Umm well if you had read the rest of the post you would see that I need this stuff today.. I don't have time to wait and order something so ZDDPlus is not an option unless they sell it in stores, but i haven't seen it. I ***umed I would get EOS and that fell through. Anyway I got Rotella T. I also was reading everything there and was reading about Lucas oil stabilizer.. is this in anyway comparable to the additives? It claims to help new engines and even ahs the balls to say it is an ***embly lube....
Maybe old school say nondetergent but all of my buddies who build and race really expencive engines say it's a must to use a zinc additive in the breakin oil. Your NAPA dealer should have or be able to get a LUCAS product (engine break-in oil aditive) TB ZINC-PLUS. compucam and others also make zinc additives. Never use synthetic oil for break-in. It's way to slick.
Well Revhed, I went back and read your first post AGAIN on this thread, and nowhere in the first post is made mention that it's gotta be today, just a brief mention of a roundup you wanna make! I apologize that I don't have an event calendar in my head that I can pull up, figure out what is the "roundup" and when is it and how far from it is Revhed and when does he need to leave to get there at whatever time it is he wants to be there! The stuff at NAPA, or whereever it was mentioned above to be sold that purported to contain ZDDP seems to be at least knowledgeable about what is needed. As for the story about no synthetic oil during break in, do you realized that some very sophisticated highj performance cars such as Corvettes, BMWs, etc. come from the factory with synthetic? Dave
GM Stopped making EOS ***embly lube I called almost every GM dealship from here to Texas (literally) and up into Canada and bought up all I could late last year. Matt
I spent 3 hours the other day reading manufacturers oil specs. Valvoline VR1 has the most zinc .13 which is similar to older oils. I think the next highest is .09 Some of the oils made for deisel engines have high zinc content too but this is made for a gas engine. An article just came out in a auto machinist mag that also agrees with this info. I will find out the name of it tomorrow. http://www.valvoline.com/products/VR-1 Racing Motor Oil.pdf Also recommended by roadrunner engineering. Skroll down to Motor oil. http://roadrunnerengineering.com/tech tips.htm I don't know much about additives but I read that they don't tell you how much zinc you are adding. I also read that too much zinc is not good. I am not an expert at all, this is just what I picked up on the internet.
Remember that almost all modern OHC engines use flat-tappet "lifters" and would be subject to the same failures as flat tappet OHV engines from the low zinc conspiracy. I think the significance of this issue is overrated.
