Rotella T 15w40
 

I searched for this topic and was unable to find any information on it. I would like to know if anyone has any experience running Rotella T 15w40 oil in their stock KA24DE. It is on sale where I work for $12 per gallon right now and I due an oil change. I have only had the car about a month and I am not sure what the previous owner was using. With spring/summer right around the corner I was thinking that it may not hurt to run something a little bit thicker I am just not sure if 15w40 is to thick. Any information is appreciated.

I think its retarded how people run desile oil in a car or bike

Dont you think if it was good for a car it would be branded so? Read up on it. Its ment for a desile, that revs to 5k on a good day. Thats the newer ones. There a million times more dirty. That rotella does not have the cleaning agents a motor oil does.

Thanks but you do not have to jump my shit about it. I simply asked a question. Also, according to the information on the back of a bottle of Rotella and a bottle of Castrol GTX they actually meet some of the same requirements, that is why I was asking. Another thing is that after reading the back of the bottle of Rotella, I realized that it does not say anywhere on the bottle that it is specifically for DIESEL engines. It simply says suitable for all modern low-emission heavy duty engines engines and no, I do not think that my KA is a heavy duty engine.

Don't you mean diesel? And also thicker oil may not pull the utmost performance out of a motor but it does somewhat prevent oil consumption and extends engine life. In our cars, almost all of them nearing 200k miles or more, if the engine hasn't been rebuilt the bearings/rings/everything else have loosened up. The thicker oil can help fill up that space. Also diesel oil has a higher sulfur content, which is better for your valvetrain.

Depends on how many miles you got on it and if its been rebuilt or not. But just use regular oil about 10w-30 if you think it has a lot of miles. But rotella is mostly for DIESEL not gonna murder you if you use it personally would just spend the money on castrol or royal purple depending on how good you treat your cars.

Yeah, you guys are silly.

Rotella t will work just fine. It has cleaning detergents to keep your motor spiffy on the inside, plus it doesn't break down under the extremely high temperatures of a diesel application.

To the guy saying that "if it were to work on cars, why wouldnt it be labeled as so?"; Well, heres the thing; It's labeled as diesel oil because it has properties that are beneficial to diesel engines. This does not mean that these properties are harmful to gas engines. This is Shell's way of simply letting diesel owners know which oil to purchase, not tell gas owners what oil NOT to purchase.

To answer the OPs question, I have always ran Rotella T in all my race applications and will continue to do so.

^ +1. i've been running Rotella T 15W40 for a couple years now in my SR. daily driven, drift events every month or two, autox too... i never have any problems at all.

I'm using this stuff right now, seems a very good break-in oil. Was recommended by a engine builder.

i am running it on my SR and its been great no problems yet

The only thing is you guys are running sr's, turbo motors run hotter he's running stock dohc ka. No need to run that thick of an oil in it, like I said before its not gonna kill you to run it but I would run a little thinner just because of the warm up effect. When oil gets hot it thins out, 15-40 is perfect for turbo applications, that thick is just more work for your STOCK motor to be pumping through its system.

ive run this oil on 3 ka24des, 2 ka24dets, 1 sr and 1 4.9L v8 in my daily driver cadillac.

I run Rotella T on both my NA/KA 240 and on my Kawi 636.

The engines run a bit better, and the oil gives me peace of mind on the track.

And the fact that it's cheaper than most other oils doesn't hurt either.

Wow i really didnt know you can use rotella on gas engines. I had the impression it was a diesel oil. learning something new everyday . lol

I will give it try since i been seeing alot of good feedback.

Its just something i would never do. Ill stay with mobile or castrol

If it works go for it.

Pretty much this. I've been running Rotella on my vehicles also and had no issues whatsoever.

For the asshole that recommended Royal Purple, well, you're just an asshole.

I always ran rotella 5w40 in my last sr with good success. Plan on running it in the sr24 as well......

Ran rotella 10w30 in my gas dodge truck
Rotella 15w40 in the powerstroke

thanks for the chime in vas

exactally
were in florida its hotter and synthetic on a boosetd motor sucks
rotella 15-40 is all i use..
boosted non boosted...with no problems
for those who want to waste money on names and promises..
go ahead...
but rotella rocks and its a damn good price

I do not understand how synthetic on a boosted motor sucks.... Do you care to elaborate?

15 is also a tad thick to pump at startup for no reason

Their synthetic 5-40 is great

Wow I would always wonder about this oil when I would go buy oil to do an oil change...I'm a castrol guy but with all this good feedback ill give it a shot and save some $$$$......learn somthing new everyday sweet!

The synthetic breaks down too quick and is too thin
I don't like changin my oil an in a week its blk
Rotella holds up better for me
I also had 6qt in my sr
Oversized oilpan
Oilfilter relocation w gm truck filter
And oil cooler out front...no issues at all

Isn't motor oil supposed to turn black after a week?

You should do more research on how oil works. Explain to me how 5w40 or 0w50 is any thinner than 15w40.

Its not, its just as thick or thicker, just easier to pump at startup. When warm they are all of the same thickness, well 0w50 will actually be thicker yet should still flow better.

Since when does synthetic break down quicker? Are you assuming this by color or do you have oil anylisis to prove this? I ask because i have seen numourious oil analisis to prove otherwise.

Also have an uncle that is in charge of a lab for a company that checks all of their fluids on all of their equipment. Its cheaper for them to use synthetic because of how much longer it lasts and how much longer it makes their equipment last

Im going to run Rotella Tsyn 5w40 on my freshly rebuilt KA. Used it in my 350Z before without issue. Its good stuff.

walmart sell's them for $12.97 a gallon

Walmart.com: Shell Rotella T 15W40 Motor Oil, 1 Gal: Automotive

Don't mean to take it completely off topic, but would like to add that Mobil Delvac is also considered a "diesel" oil. But I've had it in my n/a KADE for the last 8 oil changes using Bosch oil filters. No issues. but reading all of this, I might try out the Rotella next time I'm due.

Delvac is a good oil without a doubt...some of our customers swear by it. We however are a Rotella shop.


I personally ran 15w-50 Mobil 1 forever in my 240, but when it became harder and harder to find, I decided to make the switch to Rotella T6 5w-40 and haven't looked back. More accessible to find, cheaper, and just as good (if not better).

Ever since I switched to Rotella, my KA has been as quite as a mouse.

This maybe off-topic, but does the name Rotella sound like a name brand salsa?

EDIT: I was close. Damn.
