which would you purchase.

in my local Walliemart, 5 gallon pails of Rotella T4 15W40, 74 dollars..
other side of pallet, 5 gallon pails of Delvac 1300 15w40,,, 62 dollars.

The Delvac. Both are great oils, and I've used tons of Rotella over the years, but it isn't priced as competitively as it used to be.

I would use any of the majors name brand oil. That said the lowest priced name major name brand one.one.

which would you purchase.

For what application?
For what duration of use?
In what environment?
What ROI is desired?
Are there rebates available for either or both?


Unbounded question met with deliberate specific response.

actually, question was quite specific..... you have two choices... one or the other... you are the person making it more difficult than it has to be.

I thought you were a “any brand will do” as long as it carries the proper specification?

I am assuming either has whatever spec you require? If so, then there is no question here at all. Delvac is made by a great US company and is significantly cheaper?

Not saying there is anything wrong with Rotella, but why pay more to send money to Holland rather than keeping it here, when either would work? Serious question?

Both are lackluster, but if I was forced to pick one.... Delvac.

Lacklustre , meaning they are lacking or meadeocure.
If the prices were reversed, I’d take the RT.

I am. I usually buy Delvac, just because it is cheapest.

NOT trying to justify Delvac per se, but that advertising piece doesn’t give me enough to determine why the Delvac didn’t meet test requirements. Meaning, something is fishy because I don’t see how Delvac could achieve its API and other certifications if it performed like that.

And all that said, if this is for some new higher performing engines, and the OP doesn’t have one, does it matter? Will it make a lick of difference in my 96 Cummins or 1980s Mercedes diesels? OP needs to give more info to decide.

Again, not a justification, and if Shell is keeping XOM honest, great. But that specific piece isn’t compelling to me.

On what objective basis?

If you want great quality answers from serious folks who know their stuff, answer the questions. Otherwise enjoy the oblivion

They all are great but I go with Delvac.

if you really look at the one test in the example, assuming it is true, the Delvac slightly underperforms what is quite an extreme test, and that is only past the 300 hour mark.. in most peoples cases they dont operate near the extreme used in the test so its not particularly relevent for most people's use.

who determines which are quality answers and what qualifies those answers as coming from serious people who know their stuff? This is the internet. LOL.

Agree. That said, and I know that test and situation is many years old now, it still bothers me a bit, because how did Mobil get a CK-4 and Volvo cert? Lying? Cheapening the add pack after?

Did they blend a bad batch and Shell found it?

I agree most don’t operate there - thus my point on if it makes a bit of difference in my 96 Cummins trucks or 1980s MB diesels.

But the flip side is if I paid for a CK-4 oil with a level of anti oxidation and thickening resistance, then I want what I paid for whether I need it or not…
