I bought 2 gallons of Rotella ELC 3 months ago at Tractor Supply, got a rain check for another 4 gallons, and still no stock at Tractor Supply.

Okay, I ordered a Six Pack from Amazon, and they claim that the vendor has shipped it, but that was where it ended.

I need to flush this puppy out, and refill with good ELC, so what other brands are acceptable? I need to start shopping around.

EDIT--- Holy Cow, those folks in Dawsonville are Super Nice Guys.
he said he does not stock it, but will order me six gallons and hold it for me, he said no one has ever asked for it, so it will be there when I arrive.



Okay,
I will wait until I arrive in Dawsonville, GA in 10 days, we plan a 1 to 3 month visit with my son,
it has been over 3 years since we have seen each other.

( he has a separate apartment over his unattached 3 car garage, oh so nice for me and him )

IF, Amazon does not follow through, ( I sent it to his address )
---- cancelled AMAZON order
and use the NAPA online purchase to send it to his local NAPA store.

I will throw in here also...
Do not use ELC in early or older 7.3's unless the cups have been replaced. They are not compatible, the sealer that is.
For those that did not know.

Any 7.3 older than a early 99 is good with ELC. That implies you are good.

older... Newer.... past.... present.. well, deep hole.

Newer than an early 99.... My brain might need more coffee.

You can find it at Napa, if you don't see it ask. It may be in the back. (Concentrate)
the local NAPA in Claremore, Oklahoma says it does not exist in their Catalog anymore.

I called the NAPA store in Dawsonville, Georgia where my son lives, and they told me they would order up two cases and have it waiting for me when I arrive there next week.

can't beat that with a stick :)

Good job John, when those Amsoil guys show up (either side) things go off the rails. On the same note, thanks for keeping my day boring from following the internet arguments lol.

I would add that rotella issue for pree 99 isn't just for the cup sealant its also for silicone based seals in the Engine and head it eats at them. The way I figure its best avoid since most of the new head gaskets replacements now are silicone, can find rubber but at least for me not with harness. Just food for thought.
