    I bought 2 gallons of shell rotella ultra ELC in white container on March 1 from local NAPA store. On Saturday I ordered 2 more to complete my coolant change from blue BMW coolant . They had the warehouse deliver 2 gallons of a red shell rotella coolant in black container. I said they were not what I wanted. Got on the phone with warehouse to get correct stuff and he has it, but that the yellow ultra has been superseded by this new red nitrate free coolant, because shell discovered something wrong with the yellow.

    Any one know the veracity of this?

    The only reason they recalled the coolant was because it did not have enough stuff to keep dogs from drinking it. Function is completely unaffected. NF just means Nitrite Free, which Ultra already is.

    Here is Shell's actual recall on coolant products produced before about March 2016. Affected just about all of their coolants.

    Here is Shell's take on their coolants. Sounds like NF is actually superior to Ultra for our heavy duty engines with wet liners.

    Steve- Not yet. Aaron and John rebuilt the AC compressor, replaced the sump piece that has the drain, did a 5 year with all fluids, and the worst was installing the factory CF trim on the seats. Much more involved on the CF trim than we thought. I should owe him a pretty piece of change, even though the belt change was just a lock and swap since the cams were degreed last time. Both I and the 575M will miss Aaron and John. Not sure how good the service in Nashville will be, and that is an hour south of here.

    Brian- If you use that same web site and choose Canada as your country instead of the US, they still show Ultra as available. May just be NLA in the US, or Canada is not as worried about dogs as the US.

    The recall was 4 years ago. Hard to believe thats the issue. I wonder if it ran afoul of some new enviro rule for its contents, or possibly a new spec for an engine supplier. . Sounds like NF is a pretty parallel product anyway. I was looking at the product line, seems like not that long ago and NF never came up on my radar for some reason. Its well rated but so far the prices I see are pretty spendy.

    Funny, their URL says nitrate free when they meant nitrite free (I think). Quite a difference chemically. From what I have read, the nitrite free ELCs and their OATs are adversely affected by any nitrite mixed with them. Shell also has nitrited ELCs with Hybrid OATs and one that needs SCAs at regular intervals. Even Zerex G05 has nitrited HOATs now, so not the same as the old G05, according to their 2020 spec sheet. Might last a bit longer so my 2 year interval will really be OK.

    Sounds like the ELC NF will work fine in our Ferraris and it is a pretty color. Price is not too big a deal to an owner who pays relatively a lot more to have a pro change the coolant. I can see where it would be a disadvantage to a shop, though.

    No, it just means Valvoline has updated Zerex G05 with modern nitrited HOAT additives that still prevent cavitation corrosion. See spec sheet attached.

    I am a little confused.. why did g05 change and what did they change?

    How does the new shell formula compare to old and is it the best choice for our cars ?

    Thanks in advance

    G05 changed so the additives do not wear out in 2 years like the previous non-Hybrid Organic Acid Technology additive package. Should be even better now. Shell Rotella Ultra and NF should work fine too for up to 6 years if you are brave enough. I will still change the G05 at two year intervals because I am a dinosaur.

    In reality we wind up draining it out before then for some reason. I do feel comfortable doing it at five which is when we are doing belts anyway. Caps still only last 1 or 2 years max.

    Antifreeze is under the microscope by EPA etc and engine manufacturers demand changes too.

    I'm still going to use the Shell product. Which ever of the 2 I can get most easily. I am just not seeing a functional difference.

    Brian- Funny, because I have had the same radiator cap since I bought her nearly 12 years ago. I bought two spares, but so far have not had to use them. There must be good ones and bad ones, just like Ferrari bronze valve guides.

    On all the cars I service at most I get 2 years out of them. Makes no difference where I get them They are made by 2 or 3 companies and it seems to make no difference what brand.
