So **** me right... I was using ESP for the one oil change but then I saw this turbo diesel truck kind. It definitely was not in my area at the time of this thread... the advance autos here had the qts for clearance, like $5.50. But now I saw this price...

where is that at?
All of you are fraking fools to bash Rotella T6.... MANY owners run it in the 7.3 and 6.0!!!! I run it 10-12k (change oil filter 5-8k) and oil anyalisis shows could easy go farther. Once I went 20k and it still had almost 5-40 specs, barely sheared. It starts and idles smooth as butter and can be had year long for $19.99-21.50 on sale at Walmart, Rural King, O' Reilly's, Advance, etc. I use Purolator PURE ONE oil filters usually, or Motorcraft if in a bind.
Rotella has completely reformultaed there oils from years past. well over a million 7.3 owners have run nothing but Rotella. Longevity has been well proven.
Delo 400 is also an aazing oil. Ran it a few times and it provides a noticable difference. It also tested out very well at 10K miles. Note that all my tests were on a super high mile motor with tunes and stage 1 sticks pulling new rv trailers.

to the rotela haters. Why is it we have 7.3L engines with the original injectors at 400 thousand plus miles, since there first oil change they have had nothing but 15-40 rotela.??? that does not spell junk. We run our T6 for 10,000 plus miles between oil changes and never have a problem. not even with a idle.
the best oil to date i have run in my pickup was Cenex brand oil! Will be switching to Conklins next.

There have been several tuners and shops that have had unusual trouble that they couldnt fix and upon draining rotella and putting pretty much anything else in truck.runs fine.
My 03 that I sold in 06 had rotella run through it since 3k miles. Truck.ran like.crap and idled poorly. Had the truck at the dealer and they replaced sensors and computers. Granted thats not how I would have approached it but it was a new truck with an unhappy owner. They told me I was FOS until I brought my 2k in and showed them the difference in idle and performance. The 2k was running pennzoil. Anyway, at 100k miles the 03 started getting the pennzoil and the issues dissapeared along with the oil. Fwiw, that 03 had several injectors replaced that were worn prematurely. Different oil and things ceased to exist. I.cant say I share your sentiments but do feel different trucks may need different oils.
Rotella has not worked for me for a long time. My skidloader didnt even care for it.

funny. some pickups must just respond different. Because I have never experienced what some on here say they had happen with rotella. Well if i ever run into that problem I will see what a different brand of oil can do.

I actually found my 6.0L and 6.4L's to run better on Rotella T6, as compared to Mobil 1 5W-40. Not sure why everybody is hating on Rotella, they have came a long way since the old days.
The old days being when? I used that oil from 02 until 05 in my own truck and for a couple years more in a company truck with horrible results. I havent poured Rotella in probably three years. They made inroads in the last three years? I highly doubt it since Bean had a trouble thread up last fall that wound up being resolved by draining the dino Rotella.
If you like Rotella, thats your right, but there is plenty of proof from "the old days" up until a few months ago of Rotella suckin balls in our trucks. Having been there myself its not bs.
Are youguys running stock trucks that think its great lube oil?

T6 isn't dino oil. You couldn't pay me to run dino oil. How are you going to compare apples to oranges? Rotella 15W-40 isn't even in the same league as Mobil 1 5W-40. Get a grip, bud.
And yes, a lot of the advancements have came recently. I believe I read a few months ago that the T6 was reformulated. T6 is some of the best oil out there at the moment.
The real questions is, why in the world would you use such "horrible" oil for 8 years? LOL LOL Just a coincidence, I guess? Must've not been so horrible like you claim.

Dont know why anyone is knocking any oil. I use motorcraft 1540. My truck has had that for ten years as a ford dealer parts truck. Now I own it, lift it and beat the piss out of it.
It may be...if ford uses a certain additive in their oil, and rotella obviously has different whether full syn or not, they may react/cancel out the benefits. Run the same oil if possible. That's what I have done and will always do.
Edit: not one of my trucks has ever had less than 220k on it. And god only knows some of their previous owners and what they did to those things...

First of all, you said t6...
Second sentence you said Rotella...
Rotella refers to 15-40 shell rotella t oil.
Ive been following along in this thread and you've been talking about Rotella T also. Ummm, unless you have proof, rotella T wasnt synthetic oil even 2 years ago. So if you arent sure, better check. I would but.I dont.care to. Every oil thread for the last five-six years someone.comes in banging the t6 drum only to whine and tremble when its laid out for them that its made wih dino base oils. As it probably still is. So if you care and have a point in life to prove this, by all means, go ahead. I dont.care enough to.
I didnt use rotella personally that whole time. My truck, used the oil until I actually eliminated every possibility that it could be. Switched oil and the problem went away too. Ive poured a lot of that garbage into other peoples trucks and equipment over the years. Thats what I meant.
Not all Dino oils suck,btw. Delo 400 is better than most synthetic oils.
Ill have to take you at your word that t6 is good. You'll have to take mine when I say Ive.been around a long time and ten years of horrible performance out of an oil brand isnt something that is.easy for.people to.forget. T6 was not good oil two years ago even so maybe your frame of reference is very small?

Unless, you just didnt list it, your signature doesnt mention anything about tuning or injectors. You can run salad oil in a truck with stock fueling and have no troubles.
Aggressive tuning, upgraded oil pumps, and injectors make obvious deficiencies in oil and performance.changes are.felt.
I ran motorcraft oil in my 00 and with a 100hp tune.the oil degraded fast.
Gotta use what works best for you.
I just find it hard to believe that guys with 6L are getting good results with oils.that wont even run right in a lowly 7.3.
Fwiw, I ran rotella(dino) in my stock 06.6l and lost four injectors in the almost two years it was around.
@sickstroke-you just said your 6.4 runs.better on t6 than.whatever else. How is a cr truck running differently on t6 than mobil1? Oil has jack to do with idle quality or anything else you would be able to notice. Im pretty sure the dealership puts rotella(dino since you get confused) in my 12 dmax. Yea, those.trucks dont give a rats ass what you lube them with.

T6 is Rotella. Are you being serious right now?
And I've only made two (now three) posts in this thread. Not once have I mentioned Rotella T dino oil. Get some glasses and stop making stuff up. You just lost pretty much all credibility. T6 isn't Rotella? LOL C'mon, give me a break. It says it right on the bottle.
I still find it hilarious that you ran "horrible" oil for 8+ years.

Oil quality doesn't affect the idle? LOL
First you say T6 isn't Rotella. Now you say oil quality doesn't affect idle or any aspects of engine performance. What's next, we didn't actually land on the moon? LOL

you all can run whatever you want in your trucks, ive said many times on these forums how, many oils, have performed in MY truck and stated WHY i wont run certain oils... amsoil, valvoline premium blue, and chevron delo are the only oils that have ran worth a fiddle *** in MY truck and the only ones i will run... these three oils are the only ones that had the same running characteristics. used the least amount of the valvoline between oci's so thats what i stick with. the rest is chit in my book....

what injection system do you think would matter the most in idle quality for a certain oil used? heui, which uses the oil to RUN/FIRE the entire injection system or common rail, which uses absolutely no oil what so ***in ever in the injection system?
