diesel oil on sr20det

[Options13]

i have searched and found only 1 post about how diesel oil is good for our turboed engines (sr20det)

on my motor right now i am currently using 15W-40 amsoil diesel oil for my motor, my friends are saying is way to thick.

does anybody else use diesel oil? is there any benefits/downsides?

i see a lot of people running 10w-30, but i hear that, that is practically water in the summer time.

[rb25_s13*CHUKI]

In summer time I run 20w-50. winter 10w-30 non diesel oil

[karl wasabi]

I run Rotella 15w40 oil all season in my daily and my RB20 powered 240.

It works great for my 6 cylinder cars. I've never tried it on anything else though.

[2fast4y0u]

i ran ams oil 20w 50 for a long time. i am an ams oil dealer so i tried it out and loved it.
i now run valvoline vr-1. straight 50w
thinking about switching to brad keen, green oil. heard its awesome.

Any major oil brand is going to work fine. Rotella T is a nice oil (what we run in our big rigs) but I personally use Mobil 1, as it's often easier to source when going to events or tracks.

All my vehicles run on shell rotella 15w40. AMC 4.0L striaght 6, ka24e, mopar sohc 2.0L. My 7m runs whatever the cheapest garbage i can find.

The high amount of detergents in rotella is nice.

[Homer_Simpson]

Currently its Mobil 1, but I'm going to try Rotella on the SR the next time I change my oil. This stuff could be found at Walmart so it seems that availability is not a problem.

[Prok0]

I run 15-40 diesel oil in my SR.

Lots of detergents, and lots of zinc. Pretty sweet.

[besTint]

wow, really? diesel oil? hmm... sounds interesting.

[TheRealSy90]

I run Mobil1 15w-50 full synthetic year round, never had a problem.

need more info on this.

[fliprayzin240sx]

I run either 15-50W Mobil1 or 20-50W Royal Purple...

Whats there to know, the diesel oil has more detergents then regular oil for the most point, so your motor stays clean.

And diesel oil generally has much higher zinc levels then conventional oil (EPA mandated levels be significantly reduced in conventional oil, but not diesel oil)

Go on google and search for Flat Tappet camshaft failure and low zinc content oil...
Flat Tappet Cam Tech - How to Prevent and Fix Cam and Lifter Failure - Hot Rod Magazine

SR is basically a flat tappet style motor, and zinc is good for flat tappet style motors/ all motors in general.

The only reason they really dont recommend using diesel oil in regular cars is that the added zinc clogs/fucks up cats, but who on here with a modded SR is actually running a cat?

so the mobile 1 delvac oil is ok?

[Options13]

thank you prok0, the answer i was looking for

[JeremyR]

just switched to the rotella 5w-40 full syn today...gonna see how i like it, was tempted to try the 15-40 but not sure if i wanna switch to the conventional..

i DD my sr20 btw. CA heat is killing me and royal purple 10-30 was not doing its job

[j20accord00]

i ran rotella in my f250 till i switched to valvoline premium blue synthetic.

imo valvoline is a way better oil then the rotella..my dad runs the valvoline in his 250, 350 and 550 now and likes it.

my uncle owns a truck shop and has rotella on tap. hes old and swears by it.

If i was using diesel oil in my car it would be valvoline. its expensive and kind of hard to find. I order it from napa.

and my truck is no "work truck" by any means

bitch please, you don't DD your car...

[vvtisupra]

its pretty simple. Off the shelf oils have to comply with certain ratings as far as emissions and additives. diesel oils are more lenient. Zinc content which helps decrease wear is higher in concentration.

however i run the good stuff
15-50W Neo Synthetic all day

[shinobis13hb]

how isdeisel on the track ? does it break down les,s more , or the same?

[slider2828]

Are you for realz? Just run amsoil signature or hi performance 10-30 or 10-40... but seriously amsoil makes the best oils period no doubt. Why would you also run diesel oil, I just don't get it... Personally I run Redline or Amsoil HI Perf and definitely turbo sounds nice and smooth and I swear spools better than mobil 1 because I ran that before....

But then again I track and also street my 240sx but I still change oil like 3000 miles or less.... So hard to say on longevity but amsoil really doesn't blacken like any other oil, which I assume is break down of the oils....

Thats all that Garage Boso uses on the S15. But yea, i guess its all about the detergents in them. But I think you have to change your oil more often ? Dont recall.

[Options13]

well amsoil is available locally for me, and i want to get 15w-40 but its only available in diesel oil, not high performance.

so i guess im just gonna pick up some more 15w-40 diesel amsoil tomorrow! hasn't failed me yet.

[slider2828]

You can order it too from their website, its about the same price as picking it up except for shipping... you should also look for local amsoil dealer from people not from stores.... those guys will hoook you up...

I have ran Mobile Delvac for the last 2+ years in my turbo car's its the shit. Some say rotella some say AMS oil but to each there own. I ran Royal Rurple for a long time till i was told buy a pro am drifter about Delvac and then went to a mobile 1 oil showdown in Torrance Ca and mobile 1 beat most oil's plus i found out way more about Delvac. I pay $16 everytime i change my oil on my sr ................... Delvac + K&N filter = pure win.

Im convinced amsoil is more or less a ridiculous marketing ploy brought against retards and rednecks. The shit is honestly not that great. Me and a friend did some testing when we rented out a local drag strip, did passes, pulled oil samples to send off to Blackstone to have analyzed, and then changed oil/filter, and of the 5 or so oils we had tested, amsoil, some valvoline, mobil, and like redline or something, dont remember exactly as this was 5-6 years ago, mobil 1 performed the best, and its readily available. We didnt test any diesel oil though, but Im sure it would perform relatively well..

And as for the blackening of the oil, it has to do with the amount of detergents in the oil, the more detergents in the oil the more it is going to pull contaminants from your motor and leave suspended in the oil, leaving the black dirty appearance... Its not that the oil is breaking down, its that its doing its job...Thats why when you use diesel oil (which have high amounts of detergents) the oil appears to dirty more quickly then other oils...

[sirfallsalot243]

5-6 years ago was also when Mobile 1 was a REAL synthetic. Those days are long gone.

I run a cat on my sr and i haven't had a issue yet. I half to around here the home owners association makes me. If i take it off for even a day i get told my car is to laud and i got to park it on the next street over.

Yea actually i heard about the delvac the same way but some more advanced racers but was a little uneasy. I guess the next time i change my oil thats what im gonna do but the temp does change pretty drastically in new york so 10-40 for the winter now.

Also i doubt a cat will make the car Sound different if you still have your resonator and mufflers in. I dont think catalytic converters fluctuate tones or frequencies just the amount of debris and fumes cars emitt.

The cat dramatically lowers the tone. I have a full 3'' exhaust when im not home for a while i will put in the test pipe but now im to lazy to do it so i just run the cat. The cat loweres the drone and noise.

wow never knew that. good to know tho.

is it a straight pipe or do you have mufflers and res. and etc?

i know i used to get complaints too in my old neighborhood it was a little ritzy and snotty. got a letter in the mail every day.
