cold start/oil ?

[NLeach]

Ok on cold start(my last 2) with temps 30-35 she sputters and bogs down quite a bit. I know about the grid heater and the volt meter did show lots of movement but should the grid heaters cause the engine to bog down?It was enough for the wife to ask me why it was doing it. Also picked up some oil(valvoline premium blue). I know things are changing with the ULSD but the container had all API services listed. CJ-4 all the way through CH-4 and then under that says its CI-4 Plus. I know that I should be using CI-4 so is this oil the new stuff rated for ULSD that is supposed to have less soot control and all that or is this good oil to use in my CTD?Its and 06 with 1900 miles.

your cold start sounds normal... . 30-35 isn't really that cold. idle should kick up to 1000rpms after a bit to compensate for the heating grid pull if you don't touch the pedals. if you don't already have one get block heater plug/cord... search the boards its easy to install.

The engine should change pitch a bit each time the heaters cycle, but the change in RPM shouldn't really be noticeable on the tach.

Yeah it is. My '04. 5 wiggles the tach 25-50rpm, even at the automatic high idle. If you have the defroster on that makes things interesting as well.

C'mon, the maximum resolution on the tach is only 100 RPM. Maybe you can see 50 RPM, but 25?

Not trying to start an arguement here, but you can't see the tach move unless it moves an entire mark?? Sometimes it moves halfway between the marks, sometimes less.



And no, I have nothing better to do while the truck is warming up than sit and watch the tach move.



25 rpm is an estimation, not an exact measurement. smartass comment approaching If you'd like I could change the display on my attitude to show rpm and tell ya for sure how much it moves.

Okay, you're right, I suppose you can see it wiggle a bit.



I guess my point is it's not swinging by a couple hundred RPM.

CJ-4 has more soot control because it's for the 07's that produce more soot in the oil. The claims are it also has better wear charictaristics than previous oils. The claim is up to 50% better.

There has also been reports from guys up here in the extreme cold climates that claim the CJ-4 oils seem to pump up better at startup.

There is also less ash content in CJ-4 oil.

Add in the fact that there is less sulfur in diesel after switching to ULSD, so there will be less soot in the oil.

My personal opinion, use it and be happy, it's been tested and approved by the API.

TDR issue 54, page 11: "If you have an engine equipped with a DPF, you should probably use API CJ-4 oils. You really don't have a choice unless you want to clean your particulate trap more frequently... ... . If you don't have an engine equipped with a DPF, by all means utilize an API CI-4 oil! Your engine will thank you for it!



Reason... . the API CI-4 oil has more effective and proven detergents and wear additives than the newer stuff. FWIW

JJ,



You probably didn't realize you did this... . but you misquoted the TDR. It actually states that if you don't have a truck with a particulate trap use a CI-4+.

 

[jjdiesel]

Arkapigdiesel... thanks for the heads up, you're right. I actually got it right on the second quote, screwed up on the first one! Glad you caught it, don't want to mis-inform the TDR brethren.

So is the valvoline rated CJ or CI?It states both(as well as CH and CF) but in the SAE circle that states all API services it says only CI-4 plus on the bottom but again says it exceeds all the other API services. No where on the bottle does it state its for 07 or newer diesels and also no where says its good for ULSD.
