Rotella Oil ?
Rotella Oil ? Hi guys I was just wondering if any of you have run this oil in your cars. This is what my dad runs in his gen1 350 but I was just wondering how it would do in a new engine ?

It's typically used to break in a new engine with a flat tappet cam, which your dad might have. It's used because it's inexpensive and has a higher zinc content than most.
Beyond the break in period I do not believe it's commonly used.

It was one of the oils my engine builder recommended but my bearing clearances are not stock. In the past I also ran mobil one and never saw any wear at tear downs. I'm using Royal purple now because they have it in the weight that I am using and when I'm across the border I can pick it up for almost half of what it cost up here.
The Rotella T(or also called T6) in the blue bottle is full synthetic 5W-40(similar to a nonsynthetic 15W-40). Its very good oil. I run it im my cars/trucks/and my 08' Honda CBR 1000RR.. Do a search for it on the net. You will hear nothing but good things about it. Used by alot of racers and has had alot of BlackStone oil tests done on it...

the older rotella was great for flat tappets (like my 72 454) but the newer stuff has less zinc and phosphorus than it used to. It still has a lot however the problem in running it in a modern gasoline engine is that the phosphorus will clog up your cat. common theory is that for a flat tappet cam you need 1200ppm of the zinc/phosphorus combo called zddp. i have seen a lot of virgin oil analysis reports on the new rotella that puts it right at 800. i ran the synth in my 07 600RR race bike, my 68 mustang and my 72 vette. my C5 gets amsoil or mobil because they dont have the components that will clog my cats. (of course i dont have cats anymore so it is a moot point)
The oil mfg's at the 08 SEMA training seminar I attended stated that its only a theory that less ZDDP will prolong cat life and there is no scientific proof for cat failure attributed directly to ZDDP. Also, the level was lowered to 800PPM from the original amount of 1200PPM. 1200 PPM happens to be the critical threshold for proper protection from the ZDDP according to the people who held the seminar, Spectro. This statement was also backed up by the two people from Torco Oil who were also present.
ZDDP protects metal parts from scuffing whenever the oil layer is not present and acts as a sacrificial layer. People consider it less of a crucial additive now that we all have roller cams.
Personally, I use only oils that contain high levels of ZDDP. Torco, Valvoline VR1, Amsoil, and SOME Rotella oils have higher ZDDP. Check with the mfg. for content to be sure that you're getting something with the 1200PPM minimum. Anything less, and you shouldn't concern yourself with the content.

I run Mobil 1 racing 0w-50. 1850 ppm of protection.

CJ-4 = current spec. Haven't had issue with catalytic converter or even DPF which is i'd think more sensitive.
I wouldn't say phosphorous "clogs" the converter, introducing metals to the catalyst looses its efficiency over time (oxygen storing ability).
I run the rotella t6 5w40 in my bike, audi S4 and Vette for the last 3-4 years. Vette got up to 302 deg oil temps on the road course last year with no problems (not that I like it that high 
) Oil did thin at this temp, but with some relaxed driving it would cool and pressure was good. No problems with the car and it does take a beating.
