Relax, they are redoing there website right now bc on the two new oils they will be releasing. Mobil 1 R and SUV. I've noticed this as well. FAQ are gone two. Tech told me the new website should be up end of Jan to early Feb.
I personally have not had reason to check any Mobil datasheets in about 8 months. I usually save the HTML if a web page, or download the Acrobat pdf if available.
This had me concerned, so I immediately checked out the specs for Delvac 1 at:
I was floored! This is Advertising Copy, not meaningful technical data. No HTHS, no CCS, no MRV. Hey Mobil, WHAT GIVES??
For comparison, I checked out the Delvac 1300 Super specs at:
And they DID have HTHS and some CCS/MRV results. Not as much technical data as I would prefer, but WAY more than the Delvac 1 "data."
I couldn't believe it! I then checked out the specs for Mobil 1 0W-30 at:
Just what exactly is going on here?? Does Mobil figure we're too dumb to read/understand technical data?? I can see that attitude with generic automotive oils, but NOT with their high-end Delvac 1!
It looks like some artsy-fartsy Graphic Artist designed the "technical" specifications page, then at the last minute threw out all that ugly data with abbreviations and lots of decimal places. Hey Mobil, I need way more than "pour point" here!
BTW Mobil, "pour point" is of no relevance to me. I need MRV data.
Since Monday is MLK Day, I imagine the Mobil techline is closed. I'm calling Tuesday to complain. This is insulting! Glad you brought it to our attention.
For your reference, I started my search at:
This is really pissing me off. I want to see the data for all of these. Plus, the NOACK data used to be available on the Esso Mobil Australia page-- not any more! They've converted to the horrible datasheets too.
I don't dare call Mobil tech support, we've all seen that gets us 5 different answers for 5 calls.
Well, now I'm REALLY concerned. I called the Mobil techline and the guy on the phone was a DUFUS.
I wanted to know the MRV BPT of Mobil Delvac 1. Remember, this is their el-primo HD commercial diesel engine oil. It's $$$ and is supposed to meet all the builder approvals.
The guy said:
"Well, it pours at -49."
"So what's the Borderline Pumping Temp?"
"It pours at -49, that's it."
"No, I'm not asking what the Pour Point is. That number is useless to me. I want to know the Mini Rotary Viscometer Borderline Pumping Temperature as defined by ASTM D4684."
"The motor is a rotary vis-o-meter what??"
Just to calm down after that "amusing" incident I brushed my cat so hard he went bald!
