substitute for GM EOS? [updated 5/4]

[joflaig]

I use Valvoline VR1 20w50 in my flat tappet cam 440. Folks have mentioned here one should add a bottle of GM EOS at oil changes, but it's no longer sold. The clsest thing I could eee in concept was Sea Foam, but I'm not sure if that's any good. Anyone have some other recomendations for an additive, or something apropriate?

ZZDP + or Comp Cams breakin lube will work. The pn for EOS has changed but ti's still available as far as i know....

Thanks Ron. I've had 0 problems with "your" motor, though one tire went flat over the 6 months of winter storage!

I believe LUCAS is producing one now as well... TB Zinc Plus if memory serves

It's going back to the shop in a week or two for a new steor system, more sound proofing, a tac on the coulumn and a couple of other minor things, should be out of my hands for a month or so. The only really funny thing is the iginition. It all new wiring harnesses, a new MSD box and a new high-pro starter from MOPAR, but when the engine isn't warmed up it takes for or 4 or 5 times to turn over. When the engine is warm, it's stats every time. Anyway, they will look at that.

I went to GM parts today. They have EOS again, it was off the market, but is back and has been "re-forumulated". The guy didn't know how exactly. Zinc is still listed as an ingredient.

I searched the internet for comments on this, 1) it sounds like the re-forumlated version may not be satisfactory anymore, and 2) people where saying not to use the entire bottle in the oil change because the filter would get clogged. How much would I use (of this or any similar product)?

Comments?

yup, that's the price alright. I just don't know if the stuff is any good or the amount to use.

Holy Crap....that is outragous ! I bought 24 bottles of the older EOS formulation for $6 a bottle. At that price i would just use the ZZDP + stuff and call it good. Somebody on Moparts is offering it at a group buy price...time to stock up !

Can you think of a reason NOT to use the new formulation?

Yep, the Cost !

$24 a bottle X 2 oil changes per year X 20 years  = hyd. roller cam , here I come.

well, lets say your using a good oil like vr1.  your paiying around 4.50 a quart. so now your sticking a 24 dollar bottle of eos in also   now your up to 46.50 for oil and additive.  at this point 10 dollar a quart joe gibbs hotrod oil is looking real attractive!!!   im seriously thinking about ordering some comp cams additive from summit at 10 bucks a bottle.


   ron, i never expected eos to get that expensive or i would have bought a couple cases. i always bought extra when i bought it but only a few bottles at a time.

Along with the Lucas product TB Zinc Plus which costs about $10 ea., there is also the Howards Cams product Max ZPM which costs about $8 ea., and I'm sure a number of others these days as well. I know the Lucas product can be purchased in bulk quantities for greater savings, and it's probably the same with the others as well. You can have the GM product...
