Filling oil filter when changing oil?

Recommended Posts

Posted (edited)

I am in Canada. Winter is approaching. We can and do see ambient temps to about -28 celsius (-18.4 F) around my parts. My 98.5 24V has a block heater, however that heats the coolant in the engine water jackets. It's does nothing to heat the oil in the pan or the filter housing. I have chosen to put Caterpillar CK-4 5W40 synthetic oil in my engine this winter. I choose Cat brand because I work at the dealer and get employee pricing! The CK-4 oil has been proven to have a higher level of oxidation wear protection. The PAO  base oil is proven to flow better at colder temps.  So I chose synthetic.

 

My truck is not a daily driver. It is used as needed for dump runs, picking up building supplies etc. This winter it will sit for weeks between starts. The engine will warm up, but local trips are not long. I want to ensure my engine oil is doing the best in my application. I like the temperature range of the 5W40 oil, shown here. That's quite a spread and takes me right down to -30 C.

 

The benefits of synthetic oil, the unique pricing I get, the ambient air temps where I live, it makes sense to me to use it. I don't think I'll pre-fill the oil filter.

Another beer wasted through my nose :lmao:. Was not a synthetic one either.

Actually it does...  When the block heater is on, depending on how long in relation to the level of cold, the engine block will reach a max temperature of about 100* F.  That means everything in contact with it will be much much warmer than just sitting in the cold.  If you use your block heater then oil pressure is almost immediate even in the sub level cold. :thumb1:

Probably depends on how many where consumed?

Thanksalot Dipley :lol:

 

I would plug in the block heater because even in my temps where I don't need it much I see quicker oil pressures at start up even in + 28 degrees.

At home I park in the garage which typically stays above freezing barely. Once on the road I could end up leaving the truck parked in subzero. I just cycle the grid heater twice and hit the starter. These are not Ford Powerstrokes that need block heater and battery charger to start in the cold.

Grid heater,  Mine is disconnected

 

Someone was going to make a easy on/off switch disconnect, so you can use  the grid heater to get it started in cold weather, then use a switch to turn it off (or disconnect),

 

What ever happpened to that Idea or has anyone done this? What kind of heavy duty type battery switch is available

Out of curiosity and I really dont know...

Why is diesel harder to start when cold.  Pistons still compressing the same.  

Not talking about diesel that is frozen in line somewhere.

Talk to @IBMobile he's working on a smog friendly grid heater switch.

Not enough heat energy to light off the fuel. Grid heater heat the air in the manifold. So when the air is drawn in there is now enough heat energy to light the fuel.

That would be nice to have.  Just curious too but does the switch also override the intake air heater relay circuit so that it doesnt throw a code?

Cylinder heat is generated by the higher working compression in a diesel engine.  So if the piston isnt moving fast enough during the compression stroke then the combustion chamber heat wont be adequate enough to ignite the injected fuel.  When your intake temperatures are too cold and the combustion chambers are not warm (cold engine) then the piston can have a hard time building enough heat for optimal combustion.  Combine this with weak batteries or dragging starter and you have a crank that simple cant move the pistons fast enough to build the right amount of heat to start the engine.

 

Gasoline engines dont have this problem because spark plugs ensure combustion.  But high compression gasoline engine can more easily pre-detonate because of the heat.

Haha... been out in the woods for a couple weeks and just catching up. Can't say I expected to see that chicken!!

 

I run synthetic for several reasons, one is the oil change interval. I like being able to go once a year on a change. The other is the better performance cold and hot. I have seen as low as -30°F in the truck, and oil temps as high as 240°F. Those are temps where synthetic does better. 

 

I ran dino Delo for a winter 5 years ago, and the difference in motor sound and oil pressure indications even on above 30°F days was noticeable over the Amsoil AME I run.

I will be running conventional this oil change for 1 reason. I bought 2 extra gallons while changing oil in someone’s 12 valve so I might as well use it and not return it. I think I will jump right back to synthetic though. Prob will continue running what the P.O. did. Rotella T6

I saw a guy change to synth one time... after about a hundred thousand there was oil all over the engine from leaks

There is alot of misinformation about synthetic oil. Like @JAG1 points out he switched to synthetic and it made it leak all over. Not necessarily the case. Synthetics are designed way differently and they clean sludge off of seals and gasket surfaces or corners of the engine etc.

Basically if you run an engine with conventional for however long and suddenly you decide your engine deserves synthetic oil, dont. Your engine will already have a nice coating of sludge keeping your gaskets and seal from leaking. You change to synthetic and it will clean all that junk out and suddenly your leaking all over the place.

And like @AH64ID says about temperature. Cummins actually suggests using a 5W40 synthetic like the shell T6 (which is what the dealerships use) for weather at or below 0*F and 15W40 if your above that. 

 

Moral of the story- pick one and stick to it. Hopefully you can find out the service history or something so you can make sure you use the same stuff the previous guy used. They say if you have less than 100k you can safely switch from conventional to a blend or synthetic but i disagree personally. Thats 100k miles of sludge and wear. I use conventional Shell Rotella 15W40 which i believe is the T3? but thats because its easy to get since thats what we put in all the diesels here.

That’s the T6. I’m using the same. I’m changing oil tonight and switching from Napa to Fleetguard filter and from Rotella 15W-40 to Rotella 5W-40 synthetic. I see no reason not to run 5W-40 year round.

@Marcus2000monster they dont specify that you have to change I think they just mean if your going to be in really cold areas or live in a really cold area to use the 5W40. We used to sell it as an upsell at the dealership i worked at in southern california. No problems caused by that yet and its been years. Only problem I've ever seen caused by oil to a cummins was a tech forgot to put oil back in it and obviously that will cause an issue haha.

 

As far as oil filters I use the mopar filters that we get from chrysler which come from cummins (idk who the manufacturer is) and fuel filters i use factory which is fleetguard. Employee discount is nice for that for sure

Correct, you can run 5w-40 year round. It doesn't even take really cold to switch to 5w-40, just operation below 0°F. 

 

The manual doesn't talk about synthetic 15w-40 but it's generally good to -20/-30°F.

I may have to dig up that video...

Well... that was easier to find than I expected. 

 

 

That's only 5° below the lowest recommended temp for dino 15w-40. It makes it easy to see why the recommendation is in place.

@AH64ID I have always respected your opinions here and that will not change. I have always run Dino oil and always will just me. But I have nothing against the synthetic and folks seem to get good results from both. Please dont stop putting info out here for us to judge by. After all this is why I run the filter I run. Thanks.

 Just dont tell me it is no good anymore. I am running about 10k on them with no UOA. Never done one.

 Going to have to replace the head gasket real soon and we will see what the top end looks like. 100% Dino with various filters over the past 450k. I do and always will value your opinion here just as several others I have come to know.

Good words they’re chikin man! I’ll always value the opinion of everyone here. 

 

I am now running Rotella T6 5W-40 Synthetic as of 1 hr ago and a Fleetguard filter. I plan to stick to this combo for the rest of the trucks life.
