Has the formula for GM EOS chanaged?

I was at my local autoparts shop today looking for some EOS. They were out of stock and the fellow behind the counter said that he had heard that the formula had changed recently....

I was hoping to get a large quantity of it but now am hesitant. Charles, Steve, you guys heard anything? I am doing an initial start up on my motor here in the next 10 days and wanted to add this to the 30 wieght non detergent oil for break in and then continue to use it based on what I have read here....

Cheers

To the best of my knowledge, every GM dealer is out of the product. And, from what I heard, EPA banned this product due to the high Zinc and Phosphorous content so in other words, GM won't be producing any more EOS.

One of our members on another board dropped by a Chevy and GM dealer , no luck but when he went to a couple of Buick dealers, they had a few bottles in stock.

If that is the case, can we assume that the EPA will ban STP 4cyl oil teatment as well...?

I heard the revised veriosn of Mobil 1 15W-50 has restored the amount of Zinc & ph.



1 15W-50 provides higher viscosity, designed to provide extra protection for performance vehicles and vehicles that operate in severe service, such as towing, hauling and racing. Additionally, Mobil 1 15W-50 contains higher levels of anti-wear (ZDDP or Zinc DialkylDithioPhosphate) that may be required for certain racing applications and camshaft designs. This is a new Mobil 1 15W-50 formulation and is not the same as the product that was marketed a few years ago.

Mobil 1 15W-50 exceeds warranty requirements for gasoline engines where an API certified oil is specified. It meets:

API SM/SL

Requirements for Diesel Powered Vehicles where an API CF or API CD is recommended

Provides extra anti-wear additive for older vehicles
Mobil 1 15W-50 is also recommended for older valve train designs that may benefit from a higher level of anti-wear normally not required for newer generation vehicles. Mobil 1 15W-50 will also provide better anti-wear protection for higher valve spring tensions in certain racing engines.

Hi Jeff:

I have no first-hand knowledge of any discontinuation of EOS but I will find out. We bought several cases at our last purchase but I'll speak with our local dealer and see if they know anything.

If the EPA did mandate its removal from the market, there are other like products that will do that job very nicely such as the various break-in oils from Brad-Penn, Joe Gibbs Racing, and Torco with their excellent MPZ addititive.

Yes, EOS is discontinued. I purchased everything in a 100 mi radius to me, which consisted of 31 bottles, at well over three times what it used to cost me in bulk. I didn't believe it was discontinued myself until I went to get it and all my normal sources said it was no longer available and was verified by my local dealership's service counter.

I've been told that the Crane Cams Super Lube is high in Zn and P, but I don't have any virgin oil analysis to back that up, and it's half the volume of the EOS.

if the EPA is cutting back EOS because of Zn and P amounts, will oil manufacturers follow suit? ie, Castrol GTX was listed in your report as having 1200+ppm of Zn and P. Should I expect their additives to decrease?

On such oils with high Zn and P, is an additive resembling EOS necessary?

Matt:

Oil manufacturers already HAVE followed suit and reduced the ZDDP content of their passenger car and diesel oils.

There are a few that offer products made specifically for older cars and race cars such as Brad-Penn, Redline, Royal Purple, Swepco 306, and some others.

Mobil reformulated (again) their 15w-50 product with sufficient ZDDP for those that use it. Mobil's V-Twin MC 20w-50 oil has lots of ZDDP but take some effort to locate it.

One should use an additive when starting and breaking in a new engine.

I was told that the EOS was discontinued not because of EPA but rather that GM no longer sells a production car with flat tappet lifters, which was the primary reason for having this product around for dealers to use on warranty repairs. Some pencil pusher probably though it was a good idea to discontinue it, not realizing that it was the aftermarket who was using the EOS, and still has a use for it.

I have correspondence from Castrol that the GTX 20w50 will remain at it's 1300-1400 ppm levels and that their new Syntec 20w50 also has those levels. I've never been fond of their 5w50 because it has less than 800 ppm, so it's good that they came up with a new version for classic cars.

We here in Australia could not get the GM EOS
I have a bulk quantity of ZDDP high concentrate,( 23,800 ppm Zn) with ratios of P and Ca similar to that of GM EOS.
Available in 500mL (approx one pint) container which provides five typical Porsche 911 oil changes. e.g. a mix ratio of 1:100 boosts the Zn of a 1170ppm oil to 1400ppm.
Cost is US $50.00 per 500mL + postage

A super concentrate of 106,000ppm Zn is also available in 5 litre (1.32 US Gal)

Initially approched this for our local solution however may be able to assist those state side.

email me at eos@ozemail.com.au for any inquiries.

Thanks
Paul

Charles, Steve and all....

Assuming I can't find any EOS at the dealers here, what additive should I be using? I think I will use the Castrol GTX 20/50 once the motor is broken in (that is what I have used for years).

STP?

Cheers

Jeff:

We are using Brad-Penn & Swepco 306 around here and only use the EOS for initial engine start and break-in on our dyno.

Once that stuff is exhausted, I'll likely use another break-in product that is high in ZDDP such as the Torco's MPZ, or straight ZDDP (there are several variants) since I purchased a quantity of that product for internal use.

You might check some of the latest VOA's of MPZ, you may be dissapointed, many additives for whatever reason have been dumbed-down too. Even Valvoline's VOST is now crap. It's sad...
Check BITOG VOA's.

Thanks for the heads-up on that and I'll call Torco to see if they had to change anything. JGR makes a break-in oil, too.

Ultimately, I may have to make my own,......

I have been buying up quantities of EOS as a service / group buy for the Rennlisters. I have in-hand 40 bottles, 12 more on the way, and 36 more somewhat locally available, without looking too much further. I currently have about 18 bottles of my stock spoken for, with a number of others interested but not confirming / paid yet. The debate on its use / need seems to be more inspiring than the "do you want some" question.

I'm not looking to make a profit at all, but rather to offer back out for what I paid for it (some was almost $10 / bottle, most was sub- $7 / bottle, plus shipping. I figured I was searching around already for my own supply, so why not do the legwork for other enthusiasts. I am looking to keep 12 bottles for my own personal use.

Hope this is ok to post this offer. If anyone's interested, please email or visit the RL thread, as I'm over there more than here. Thanks.
