Delo 400
Having trouble finding Rotella around my area for some reason. Have been getting Delo 400 at Costco. However, was checking out Amsoil site and the comparison test looked pretty ugly for the Delo. Rotella was much better.
Any opinions on this, keep getting the Delo or why can I find Rotella? (Peninsula of Puget Sound)

Remember that Delo400 is not a synthetic. It comes in a synthetic, but that's not what's normally available at Cosco. Compairing apples to oranges. Rotella isn't a synthetic either. It does come as a synthetic, but that's not what the comparison indicates. A little misleading. And, if you check the Amsoil, I don't think it meets Ford's spec. There are people that run it, but they are taking warranty risk. Delo400 has been around for 35+ years and has seen engines reach the million mile mark and more. Rotella has a good following and reputation too. Each in it's synthetic form are terrific lubricants. I use Delo400 formulated with Isosyn. From Cosco. And I don't intend on changing. As for extreme heat tests, Sure, there are tests that push lubes to the limit, but do we push those same lubes to that limit in normal operation of our 6.0's? I don't.

You're right, and this was the thinking I was under when using this oil...and after reading your post I feel a lot better.
(By the way, what is the IsoSyn anyway?) My bottles from Costco say the same.

ISOSyn: http://www.chevron.com/products/prod...prodspecs.shtmand from:

Special hydrocracked Group II base oil that can rival synthetics in critical engine performance tests. Group II base oils are more highly refined than Group I base oils which allows the oil to withstand "oxidation", or chemical breakdown, at higher operating temperatures common to today's engine designs.

Yeah, did some reading after your post. Now I am freaked out that I screwed up the break-in. I drained the factory fill at 1,000 miles to get any "leftovers" out of the crankcase, and filled with the Delo 400 IsoSyn, thinking it was just regular Delo 400. Put Delo 400 Isosyn in again at 5,000 miles and now ready for 10,000 mile change.
All the reading I have done says you shouldn't begin systhetics until 10,000 miles in order to set the rings properly. If this new Delo is acting this "good", wonder if my rings had an improper set, ready for years of "blow-by".
(Feel like a worried hen on this engine between this and all the EGR / Exhuast, stuff.)
Think I should put a "normal" diesel oil in for the next 5k to try and fix any break-in / ring seating issues or is it way too late?

Hi Steve,
I believe Amsoil does meet specs. I have been using for many years in all my vehicles without issue.
Here is the link for the diesel recommended synthetic product. http://www.amsoil.com/storefront/ame.aspx

otisthelab, I wouldn't freak out.. Delo starts the life of thousands of diesel engines every year. Fleat trucks straight from the factory. I had my first oil change at2500 miles then Delo from then on. I do not fear. My engine with only 14,000 miles on it does not smoke, and I don't expect it to.
Sorry, Dshuffert, I don't keep up on Amsoil products. I do know there was a time when Amsoil said they met spec on most things, but the big three automakers weren't endorsing them. I stand corrected.
