Hi everyone,

Just saw this on Rotella's website. Shell is showing testing that Mobil Delvac 1300 doesn't pass the Volvo T-13 testing.

I am a little surprised that the Delvac doesn't pass. I use the ESP Delvac 1 5W-40 and the Mobil 1 TDT, am have been happy with their performance.

Thoughts?

Quite a punch in the nose for Delvac. Keep in mind these are both conventional oils. Perhaps Mobil has lagged behind because they are pushing their synthetics. Thanks for posting.

Just read through the Shell material, not only are they claiming that Delvac 1300 doesn't meet the Volvo T-13 test requirements, but, Delvac 1300 didn't meet CK-4, Mack, and Cummins requirements either!

That is a big claim! Here is a copy of Shell's comments. On Mobil Delvac's website the Delvac is listed as having the Volvo, Mack, and Cummins approvals.

"The dotted lines denote the passing requirements for API CK-4, Mack EOS 4.5, Volvo VDS 4.5 and Cummins CES 20086 approvals. To pass these limits, the test oil must surpass 360 hours before breaking the API and OEM limits for oxidation by infra-red and KV 40 in the last 60 hours of the test. This sample of Mobil Delvac 1300 Super 15W-40 engine oil does not meet the minimum API CK-4 requirements or the Volvo/Mack or Cummins OEM requirements."

My thoughts? I think Mobil makes the worst products of the major players.
This isn't the first a competitor called out a Mobil product.
I bet Shell is correct on calling out the oil in question and cant be held libel because the product in question is in fact a failure.

Rotella has very robust add packs, high TBN..sold everywhere.. even JASO approved. From Generators to Heavy Equipment, Road Tractors, OPE and Powersports i think there is no better oil in applications where HDEO can be used.

Not the first, and likely not the last time Mobil has been called out for a rumble.
Currently on the Valvoline website...
" Formulated with more anti-wear additives that stay in your oil longer, Valvoline™ Full Synthetic High Mileage with MaxLife™ Technology provides 40% more anti-wear film than Mobil 1 High Mileage*."
I agree with skyactive, of the majors, Mobil sits a ways down on the list.

I quit buying Mobil in the early 80's
I know T6 is the bomb from my own experience and I started running Chevron products in all other vehicles-OPE.

That sudden explosion of degradation of the base oils is what happens when the antioxidants get depleted too much. I believe Shell’s claim because I think they are confident that the testing was performed properly and that they can defend it against any protestations by XOM.

It's funny, so many people say Mobil the best but I don't think it's all it's cracked up to be.

To be number one here all you have to do is have constant rebates.
Cheapness rules the roost here.

Not sure about the conventional oils, but Delvac 1 ESP is likely the top oil between it, T6 and Delo in the synthetic realm--it just costs too much.

I like it. Sometimes some brands are so good they are boring and you shop around but usually you end up right back to where you started.Hey, it's a hobby. Why not?
Right Adam???

T6 is awesome in my ZT's
