Absolutely, all my vehicles use rotella, cars, trucks and motorcycle. Heck, i even run it in my lawnmower.  For a more race oriented build, i will be using the VR-1 20/50 Valvoline race oil. The only difference between it and the Rotella is anti foaming agents which are beneficial for high speed operation. If you're racing a lot, the VR-1 would be the better choice but for the cruiser/odd track day guy the Rotella is fine, inmo.

well, that answers that. ok i read somewhere that the 80w-90w for the 4 speed 833 should be a non detergent type. it said that the modern stuff is to slippery and the syncros wont slow the gears as much to smooth shifts. thoughts?

[firefighter3931]

I can't really answer that question because believe it or not....i've never owned a 4spd Chrysler product  That is going to change, however, as i am gathering parts for a pistol grip installation on my 70 R/T. 

My newer (1990) truck uses a synthetic motor oil in the gearbox...5/30 Mobil 1. I don't know if that helps or not....probably not. Someone with more 4 spd experience will hopefully answer this for you.

i havent spent to much time serching for non detergent 80 90, but hve been keeping my eyes open. most i've seen have a gl-5 rating. i read this is the stuff that is too slippery. kind of made sense in the article, but, tons of people on this site have 4 speeds, and i havent seen a post with a complaint. i havent done any research on this, but i thought you would know this off the top of your head.  thanks- getting cold up there yet?

[firefighter3931]

getting cold up there yet?

Nope, it's still in the low 70's (F)...perfect weather.  I'm heading down to Florida in a few weeks so i'll be back right into the "heat" which is fine.

Better bring your tanning lotion, Ron.. The sun is much more intense here than what your use to.. 

We Floridians stay inside during the summer....

You guys are whimps ! 

You forget....i'm used to the HEAT ; occupational requirement 



Ron

[Steve P.]

It's not the heat, smarty pants.. It's because the sun is closer here in Florida than it is in Canada. Haha,,, we don't have to pipe it in down here!!! Haha......   




Ok, that sounded funnier out loud than it looks in print!!   

[firefighter3931]

OMG...LMAO....how can you argue with logic like that !     


Ron

[Steve P.]

Hahaha........  Didn't you know that Florida is the closest point between HELL and THE SUN? 

[firefighter3931]

Hahaha........  Didn't you know that Florida is the closest point between HELL and THE SUN? 

I do now !  Steve, get out of the sun right away...it's clouding perception of reality ! 


Ron



Ps. Sorry for the hijack RT Green...we'll stop now....right Steve 

[Ghoste]

Getting back on track, I seem to recall somebody telling me that the Rotella is changing in additives soon and it will not be a good choice any longer.  Any truth to that?

[Steve P.]

Sorry...   

[Ghoste]

It's okay.  It's not cold here yet either but I'm way south of Ron.

[deputycrawford]

Ghoste, there is a huge discussion about that in my post "Engine Break In". It is lengthy and informative. I opend a can on that one...

Check out deputy's "cam break in" post for some data and info. I've heard the same thing so it's something we'll need to keep a close eye on.

the desiel oils are goiing to get refomulated real soon.  the 2007  epa specs are requiring a respec. tryucks will be coming with converters on them just like cars. so be careful of the new spec. the fuel is going to take a hit also.   

[dodge freak]

This EPA stinks-why don't they go after the big oil company's and the factory's ? I live by the Ford steel plant in Dearborn MI , you should see all the smoke pouring out of those smoke stacks the air stinks around the plant also.

I just check on Summit Racing site for the price on RP oil -for the racing 20w-50 its $12.99 a quart plus extra shipping cost cause its oil. Thats around $70 for 5 quarts of oil plus $11 for a K & N oil filter. WOW

[Runner]

well, thats the nice thing about the racing oils,   or at least the valvoline vr-1 oil. it says right on it that your not suposed to use it in polution controled vehicles. the nice thing about the rotella is the price.

    there are alot of things about oils i dont understand,  like if you dont have enough zink its hard on the cam, to much and its suposed to gum up the engine 

[Ghoste]

That is certainly true about the 2007 emission specs for diesels getting tougher but they have had catalysts on them for a little bit now.  One of the offshoots of the new lower emission spec is that the engines are going to be harder on fuel.  Makes you wonder how much they are really saving.
Good or bad, I have been using ordinary oil in my 67 with the GM OES thrown in.  So far so good, but...

       the company i work for has 18000 power units, and none of those trucks have catalytic converters on them yet. 2007 trucks will ( or thats what we are told) that is with cummins isx, volov, or detroit 60 series power.  they they have had egr systems on for a few years now. 

[Chryco Psycho]

take any good oil , add Comp cams additive or Gm EOS , I wear a bag over my head when I get EOS , & you will be fine 
Were is the Bag smiley

[Ghoste]

I don't doubt you at all Runner, but I will add that I work for a company that manufactures Class 8 tractors (International) and I have hoisted many a muffler onto the side of a truck that was catalytic.  Not all of them, but many.

[rt green]

so.........does this mean run a non detergent  80-90w in the manual trans?

[deputycrawford]

Thanks Chryco!! Now you started something...My wife wants me to use the bag over my head. What a friend you are....

[Chryco Psycho]

Ooops

[Chryco Psycho]

GL5 & most syntheic oils seem to be a problem with being too slippery
there are synthetics designed to be used in manual trannys , Redline , Mopar both have synthetic Manual trans lube
or just use the proven 80-90w , not being an oil engineer I have no idea if or why detergents would make syncros not work

[rt green]

well, what i understood was the syncros are sort of cup shaped,well kind of. what they do is when you are changing gears, you have well let say 2 gears spinning. the syncro is in the middle. the 1st gear is spinning at a high rate of speed. the 2nd one, the one you want to go into, is spinning but at a much lower rate of speed.  what will happen is the syncro{brass cup} will grab the inside of the gear and speed up the gear by way of interferance fit. that way the 2 gears will mesh without grinding. remember the old,old pickups didnt have them, and you had to blip the throttle for a smooth shift.      what i understand was the gl5 80-90w was to slippery and the brass syncros wouldnt grip the gear good enough to get it spinning fast enough. i'm not a 4 speed expert and was wondering if anyone on this board has ran into this.

[Ghoste]

Could be?  I'm no engineer either but maybe that is one of the reasons the super stock guys with no synchros can get away with running automatic tranny fluid in their four speed boxes?

[BrianShaughnessy]

Many newer manual trans such as the BW T-5 and T-56 do not use brass synchros.     The synchros are made of the same stuff that automatic trans bands are made of and  these trans came factory filled with dextron of whatever the latest and greatest was at the time.   Some older versions of the T-5 used brass synchros and used either motor oil or a regular gear fluid.   A cheezy halfazz backyard method to getting an old T-5 to stop grinding was to use ford type auto trans fluid.
My Tremec uses GM synchromesh fluid at $11 / quart. 

[Chryco Psycho]

I have run into problems using synthetic oil
the syncro is a Cone shape & the gear has a reverse cone , the syncro also has grooves in the cone to give the oil  a place to go , newer syncros also have slots cut across the grooves & up the cone to help bleed out the fluid under the syncro

[derailed]

Is there any type of detergent in Rotella 15-40 that would be harmful on a higher mileage engine. Only reason im asking is because I went out and bought some for the oil change in my charger and the guy there told me to think twice about it because of the detergent in it. I really couldnt see where hes coming from because they run this stuff in big trucks with a million miles on them but maybe thats because its been in there since day one?

[firefighter3931]

Derailed, i run Rotella in my daily driver pickup which has close to 180K miles on it. No problems. This is a gas engine btw. 


Ron

[derailed]

Thats what I figured, I just wanted to get your opinion on this guys comment. I was running Penzoil 20/50 in the summer and 10/40 in the fall. I figured id use the Rotella being that its pretty popular here. Thanks

[DW]

There was an article in the June 2006 Hot Rod that talked about today's oils not having the additives (zinc, if I remember) required to properly cushion the flat tappet to cam surface.  They recommended Rotella as well.  The also said that some racing oils like Quaker States Q-Racing also have additives to protect flat tappets.

[Chryco Psycho]

Rotella does have a rating for SL/Sm gas engine application on it
