Rotella T oil users- question

Contrary to popular belief. GM EOS still has all the heavy metals in it. Thats why you can't use it in catalytic cars. It plugs the converter. If the Rotella T says advanced soot control on it its the new stuff.

 

I'd like to see a recent analysis or a recent TDS. It no longer says it contains zinc on the bottle.
GM likes to sell it with oil changes and the zinc is a no-no with converters. Cars 75 and up.

 

I noticed in a magazine article GM had both EOS and "cam break-in compound" or something like that in a photo. Anybody know what the deal is there? Maybe one still has zddp and the other doesn't?

 

I just checked out Caterpillers site and they offer a full synthetic 5-40w oil. Wonder if it also has the good aditives in it?

 

A good zinc additive is Valvoline Synpower Synthetic Oil Treatment.

 

Can it be added to a conventional oil?

 

OK. It will be time for a spring oil change on my 72 GS 455. Last time I used Rotella 10w-30 old formula. If I use the new formula this time, what zinc additive do you all recommend to fill the void?

Tks, Mike

 

Is Rotella sold or made by Shell??i`ve never heard or seen this kind of motor oil before?


Thanks

 

Rotella is made by Shell and is a Diesel oil. Up until Oct 15, 2006 it had a pretty high zinc content... but not anymore. I stocked up on the old formulation. I haven't heard of a readily available supplement to replace the zinc yet.

 

my Costco's still has the old formula - got 3 cases stashed and may grab more this weekend

BG-MOA is an excellent additive

 

How do you know whats the new and whats the old?what the hell is BG-MOA?you`re getting technical on me now Alan.ou:

 

Old formulation was CI-4, which is shown in some of the small print on the bottle. The new formulation is CJ-4.

 

I am reading here about some of you mixing synthetic oil and conventional oil . I didn't think they would blend together . Some one please enlighten me on that subject , please ..........Thanks

"Shell will have products available at the performance levels required by our customers. That being the case, Shell will produce API CI-4 PLUS products until 2010 if there is sufficient demand from our customers."

OK Thanks for educating me .

 

Here is the virgin oil analysis for RotellaT 15W40. This is the CI-4+ (pre October) flavor:

not true my 94 station car bmw 325 recommends 15 40 year round--

 

Likely because it has bearing clearances and oil pressure relief flow designed for compatibility.
