Rotella vs Mobile 1 - Page 3 - PeachParts Mercedes-Benz Forum

How large are the soot-microns compared to minimum micron filtration capability of the standard oil filter?

I dunno how true it is but someone was telling me just a couple weeks ago that the new Castrol Synthetic is suppose to be even better then the Mobil 1 synthetic. Has anyone had any experience with it yet?

I use Rotella T6 because my hydraulic lifters stay quieter when the oil gets to the end of its lifespan than when using Mobil 1. T6 is an excellent synthetic and is usually cheaper than Mobil 1.

I vacillate between the Redline and Shell's 5W40 Synthetic...
Shell's 5W40 Synthetic in "Winter" (2.5 months of 32 degree weather)
The Redline offers me a complete Synthetic with 15W40 Viscosity.(In Summer)

Neither, over 3K mileage changes.

Self Confessed Lubricant Fanatic.

Oil's Cheap...

I use Rotella T6 and faithfully change at 3K intervals - another oil OCD victim...

Sas: You like the T6 because it's better toward the end of its lifespan, and you change at 3,000miles?

JoeBob: I used to run Castrol exclusively in my jap-bikes, always loved the stuff.They make excellent oils, the only ATF that is (was) rated for extended drain in my big ZF (motorhome stuff), ... and I used to run their diesel oil in one of my CATs. Over on the VW/Audi side, lots of guys are happy with the Castrol Edge full-syn / group IV synthetic stuff, I'm considering trying it in my gas cars, ... but it's a bit harder to find in the right viscosity for my cars than is the Mobil 1. I'm willing to bet it's an excellent oil but IIRC not specifically a diesel oil.

- yeah - like I said, I have some "issues" with oil.

... and I thought I had oil issues.

I have Rotella 5W-40 T6 in my car right now. Decently priced at $20 / gallon when I was up for an oil change. If M1 TDT was cheaper, I would have used it (but, at $7 a quart...it definitely isn't). I'll probably stick with 5k intervals unless otherwise told. I'll probably send in a test just to see how I stand

Which product? In the US, most syntec grades arent much to write home about. The 5w-40 product is decent for some applications, and the 0w-30 product is highly regarded too.

But better than M1? grade to grade Id say no, and the two products I mentioned have no direct competitors necessarily in the M1 range. The syntec 5w40 is not a diesel-raed oil the way that the TDT is. Syntec 0w-30 kind of competes with M1 0w-40, and there Id say the syntec is more robust and the mobil is the more advanced package overall.

I have no idea, I just know someone I was talking to in person the other day was saying the Castrol Synthetic was a better oil then Mobil 1 now. Maybe because they put a label on it saying it's better then Mobil 1? I don't know I haven't really looked into it or even looked at them in the stores yet. Just figured if it was true someone would here would know about it.

Autozones in my area (Atlanta) are running a special this month on Delvac ~ $8/gallon. I'm stocking up!

FWIW- I have used Rotella and Delvac for the last few years and like them both.

Castrol edge and pennzoil ultra are almost a new class of oils, which seem to be super-additized, super-cleaning oils, potentially suitable for extended drains. However, they are not explicitly long drain oils like amsoil or M1 EP.

Other than the grades I mentioned, and especially in the syntec range, we have not sen anything based upon the chemistry that I would say indicates that the syntec oils are superior in any way.

babymog · #45 04-21-2010, 11:04 AM

The Castrol Syntec oils are blends, Castrol Edge oils are full-syn and I believe Group-IV synthetic like the Mobil 1 EP/TD&T/Delvac 1.
