Rottella T #312674

I am using Rottella T in my 440 Motor with about 1500 miles on it since rebuild. I heard that Rottella T is best for flat tappet motors. But I recently heard that it causes sludge build up. When I had the valve covers off every thing looked fine. I only drive about 700 miles a year. And change the oil once a year. Should I change to another oil or use the regular 10-40 modern oils with a separate zinc additive?

It might look good in the rocker area but when it builds up in the lifter valley you will have lifter failure. A good synthetic oil will protect the valvetrain. But like the show you may have watch this morning an additive with a good motor oil will protect your motor.

I used a rottella for the breakin on my motor and it worked great. Then I used a regular motor oil for 500 miles and then switched to a good synthetic afterwards. It has 3000 miles on it now and holds good oil pressure. This is my daily driver so I put about 10K miles per year.

I hear different, it is heavy in detergents an keeps the engine very clean, i don't know how often truckers change their oil but i'm sure its not 3K.

keep using it. The new Rotella doesn't have as much zinc as the old plastic white gallon jugs of it did but just add a zinc additive, use a good filter, frequent changes & you're good.

Modern 10-40 with zinc additive. Most ( if not all ) new - 2010 diesel engines are going to after treatment ( convertors ) to meet new diesel emissions specs, so you can scratch using diesel oil for the hi zinc content shortly.

Slightly OT ....

Anyone here know the designation on any oil container that indicates heavy zinc content?

I have got a couple of motors going together and will be using NON-roller cam.

I would use a roller but since the roller lifters I have heard of here and elsewhere are not reliable .....I will pass on that idea.

Again, I'd use an additive. A lot of whats out there ( lists of oils with hi zinc content ) is dated - not to mention all over the place re: just how much is in it.

Cool ...THX

Is that CI an "industry" rating ?

I am going into-town later and will stop-off at Tractor Supply and see what is on their oil containers.

They have a pretty good selection of specialty diesel and HD tractor oils.

that's where I got mine at & ~2 years ago they switched to the new stuff. Same shape white gallon jug but w a different label and definitely not "CI". I think the new letters are "CL" OR "CJ"

i've switched to rotella and i use a zinc additive and no problems yet.


prior to that, i ran mobil 1 in my 440 and didnt have any problems.

what i've herd is that you don't want to use any oil that says "energy conserving"


oil can be a very touchy subject with some people.

The new API rating for diesel oil is CJ-4. The new CJ-4 oil is Ultra-low sulfur diesel (ULSD) for newer diesel emissions. The older API diesel oil rating is CI-4+ and is getting harder to find. In fact I talked with a parts department manager the other day who told me he cannot get the CI-4+ any longer. But there are a hand full of specialty companies still producing the CI-4+ diesel oil.

Depends on the weight. In 15w-40 that is true. But you can still buy Chevron Delo CI (not even CI+) in 10w-30.
So far tests have shown that Rotella and Chevron still have marginally acceptable ZN levels (1250-1500 ppm from Staveley tests) but that could change at any time WITHOUT rolling the designation to CL.

Rotella is NOT known for sludge build up. Weight wise the most likely oils to sludge are 10w-40 due to their high viscosity improver content. Synthetics not included (they don't need high amount to reach that weight designation)

TS was closed by the time I got there but I made it to Menards .....

They have a BUNCH of Rotella that has a CI-4 rating.

Anyone see the ad that CompCams has ....with that special coating they have now ?

Brad Penn Racing oil, Valvoline Racing, and my favorite Mobil Delvac1 Full Synthetic Diesel oil. YMMV

I also run EDM solid lifters...
