Note that according to the TDS PUP it does not have a Dexos certification either.

The online specifications for Ultra and Platinum show them meeting WSS-M2C946-A, which was the predecessor for WSS-M2C961-A1. My guess is that the online specs are probably out of date. If this is a source of worry, simply look at the back of the bottle before purchasing to see if the...

Here is an interesting chart on CCS from the German site https://www.ato24.de/pub/media/wysiwyg/ATO24_Oelanalysen_ACEA_C2_0W30.pdf : In the tradeoffs and compromises that go into formulating engine oil, it looks like BMW, recognizing that CCS values inflate over an OCI, decided to go for a...

Your welcome.

I already gave it. Look, it is really very simple. If you choose M1 ESP 0W30, you are choosing to use an oil that neither Ford nor Mobil recommend for your application. If that bothers you, use M1 AFE 0W30. If not, choose whatever you like.

No. The evidence is against it.

Also you have to think: if meeting WSS-M2C963-A1 is so easy, why wouldn't every 0W-30 oil claim to meet it, thereby vastly increasing the size of their market in the US? And why did it take Mobil years to claim it after Ford specified it in their User's Manuals?

But M1 ESP 0W-30 doesn't claim to meet any Ford specifications (other than being SP), which is the topic of this thread.

WSS-M2C963-A1 (0W-30) appears to be very hard to meet. M1 AFE 0W30 is the only oil available in the US that claims to, but it took Mobil a few years after Ford first recommended it for low temperature environments. Given the size of the market, that is amazing. Here are Ravenol comments of...

Impressive! In addition to taking the king of Pour Points title, it also beats everything else in my table on MRV@-40C at 15014. But not on CCS@35C, where the winner is still HPL Premium Plus 0W30 at 4150. Thanks!

I have started a number of times at -30F or below, without drama. But I am very careful about my fluids, battery, etc. My focus on using the right fluids is why I started this thread. I have had block heaters and agree that they are the preferred solution. When I lived in MN I noticed that...

Have you actually bothered to read this thread? What about the article I posted?

It never needed to be explained to me. As I mentioned earlier, I already knew that. I have never said anything to the contrary. We are actually in agreement. The only detail that you want to quibble about is whether an oil that is so cold that it cannot be poured or pumped is a still a...

So we are in agreement then: it may not be a liquid any more at 1 degree below the point where it is still pumpable (MRV), since we "have no specifications for that" other than the Pour Point. And some companies report Pour Points that are extremely close to -40 where MRV is measured at. I...

Educate me: you have evidence that engine oil never enters solid state at any temperature, even though it can no longer flow? What is the difference?

My main observation from this test is that the cold weather aspects of oils can dissipate surprisingly quickly. My lessons: Change your oil as close to the period of coldest temperatures as possible. In a prolonged exposure to very cold temperatures, change your OCI to as short as 2000 miles...

I came across this 2018 paper “Cold cranking viscosity of used synthetic oils originating from vehicles operated under similar driving conditions” that measured how much CCS @ -31C increased for various 5w30 oils over a 1 year period with accumulated mileages up to 15,551 km. The oils used were...

One problem with this type of heavy duty carry-on when flying Air France is that it will restrict your carry-on contents plus your personal items to 12 pounds (14# + 12# = 26# which is their limit for Economy Class). A lighter bag will allow you to pack more stuff and carry more personal items...

I have noticed in areas close to beaches that many late model cars show early signs of paint failure. Go a hundred miles inland at the same latitude and the problem disappears. I have noticed a similar phenomenon in parts of the country with heavy pollen, i.e. where cars turn yellow in the...

Now that I am thinking about it, the 2017 incident at CDG was even worse than I originally recalled. After she walked away from her desk and made a phone call, she finally agreed that I was not violating their luggage rules. I knew that I had an additional piece of luggage, though, and she...
