Some Mazda 6 and CX-9 between 2008 and 2015 used the Ford Cyclone engine with the internal water pump that occasionally failed catastrophically.

Mazda has recommended FL22 coolant in these engines while Ford had recommended Motorcraft Super Green coolant.

Mazda historically use coolant without 2-EHA because they use silicone gaskets and 2-EHA deteriorates silicone. Ford historically use EPDM gaskets which are 2-EHA compatible. Curiously, it seems the EPDM gaskets might have contributed to Ford's higher rate of water pump failures compared to Mazda's possible use of silicone ones.

Anyway, Ford Motorcraft Yellow (VC-13-G and VC-13DL-G) supersede Motorcraft Super Green (VC-10-A2), however Yellow contains 2-EHA while Super Green didn't. But these are all either P-HOAT or P-OAT and technically compatible with each other.

So I'm curious whether anyone has insight regarding the Cyclone engines used by Mazda. They're manufactured by Mazda in Japan so likely to have used silicone gaskets in their supply chain which would make Motorcraft Yellow incompatible with these specific models. Thanks.

I use an email address exclusively for MA and now I'm getting email spam from movies studios from that email, even though I've had Video Data Sharing option unchecked since I signed up. Movies Anywhere also keeps spamming me with "Action Required" emails to enable Video Data Sharing.

The sub not allowing me to attach a screenshot of the email.

On a Bloomberg interview today, Richard Gelfond said: "We are big. There's not really much we could've done. We scoured the world to find film projectors"

Then he just kept talking about how many 1.90 IMAX screens are playing the Odyssey.

This doesn't really seem like the right person to be leading a publicly traded company into growth and expansion of the medium.

Dolby Cinema offers a vastly superior 1.90:1 theater experience. IMAX's only selling point is 1.43:1 dual laser and 1.43:1 70mm film. Conflating the numbers with non true-IMAX screens doesn't serve the long-term viability of IMAX.

A vulnerability in Apple’s “Hide My Email” tool lets almost anyone discover a person’s real email address that is supposed to be hidden by the feature, and Apple has failed to fix it for more than a year, according to a security researcher and 404 Media’s own tests.

404 Media is not revealing the exact details of the vulnerability because it can still be exploited as of Monday, when 404 Media verified the issue with one of our own hidden email addresses.

”Apple Hide My Email is leaking email addresses that are supposed to be hidden. We reported the issue and replication instructions to Apple over a year ago. We don't know why it hasn't been fixed, but we don't feel comfortable waiting any longer. Hide My Email users deserve to know that it may be possible for attackers to discover their hidden email addresses,” Tyler Murphy, the co-founder of EasyOptOuts, which discovered and reported the issue to Apple, told 404 Media.

“Free, publicly accessible people-search sites make it easy to link an email address to other personal details, so people relying on Hide My Email for safety may be at risk,” Murphy added.

Hide My Email is part of Apple’s paid iCloud+ product. It lets users generate an anonymous email addresswhich they can then use to sign up to services or email people with instead of their personal email. These email addresses are often two random words and a number ending in the @icloud.com domain.

This can be useful for all sorts of reasons: to reduce spam; to create an account you may not want linked to your personal address and identity; and to not have your personal information held by a site that may later suffer a data breach. I personally have generated more than 400 email addresses with Hide My Email, for example.

To test the issue I generated a new Hide My Email address and provided it to Murphy. Around five minutes later, he replied with my real email address linked to my Apple account which was supposed to be hidden.

“We don't know the full scope of the issue, but in our limited tests with volunteers, 100% of Hide My Email addresses were exploitable,” Murphy said.

Murphy first reported this issue to Apple in June 2025, according to a copy of Murphy’s messages with Apple he shared with 404 Media. A month later, Apple replied and said it was looking into the issue. In March of this year, Apple said it had “addressed the reported issue in a recent system change.” But Murphy found the issue had not been fixed. He provided more information, and later that month Apple said again it was looking into it. Apple said it was still investigating in May.

“We are still investigating this issue. To avoid placing our customers at risk, we would appreciate you not disclosing this information until our investigation is complete. We appreciate your assistance in helping us to maintain and improve the security of our products,” Apple wrote in May.

“It seems that ending new sales of Hide My Email until the problem is fixed would be an effective way to limit the number of customers at risk. Is that an option?” Murphy wrote back.

At the end of May, Apple said it was planning to address the issue in a future security update “expected in the coming weeks.” Murphy then contacted 404 Media on Monday and provided details of the issue and his statement saying, “We don't know why it hasn't been fixed, but we don't feel comfortable waiting any longer.”

Apple did not respond to multiple requests for comment from 404 Media.

In June, TechCrunch reported Apple plans to make changes to Hide My Email that will make it significantly less effective. It will change generated email addresses from using the @icloud.com domain to @private.icloud.com, which means websites or services will be able to more easily block signups from those addresses.
