2014 D13 Oil temp.

If a 2017 DD13 had been running at max 220 degrees (normally 210-215 degrees) at about 50 psi once warmed up, then after a 220k PM started running a constant 223 degrees and never dropping lower than 60 psi, would that be indicitave of an oil over-fill? The numbers aren't alarming but the change is cause for interest. Same oil type as before. (Ever heard of a dealership forgeting to replace a filter?)

 

What oil did they use?

The truck came with 10-30 from Volvo.

These shops love putting 15-40 in and it causes higher pressure with reduced oil flow.


Oil temp and coolant temps are different BTW

 

My engine had that tick like you described. Many times I had it checked for cracked manifold, exhaust leaks, boost leaks...nothing. Gradually over time I started losing mileage and power. Now it averages 6.5mpg pulling 5k lb loads and falls on its face on hills. I recently had it smoke tested again. The smoke machine was pushing smoke out of the oil fill cap. Also something is causing the coolant to blow out the bypass lines on the reservior. I ran 10w30 mobile forever..then tried T6 Rotella 5w40...truck didnt like it. Vibrated more. Went back to 10w30 semi sythetic Rotella. Truck runs smoother. Oil pressure has always been 30-45 psi at idle...60psi down the road.

 

Most likely cups. They cause a myraid of disastrous results in thesr things.

The ticking sound is sometimes compression leakage into the cup.

If you're losing power and mpg it usually keeps falling until it leaves you stranded someday. The soot and air displacing fuel causes injector damage too.. (abrasive soot and lack of lube from fuel)

I wish someone would start a class action against Volvo for these dumb things.... Including the now known short lifespan of the faulty emissions SCR boxes !!

 

I just noticed ours, 2013 D13, hills under load, it will climb to 240, and stay a there for a while.
We used 15W-40, as that is what the volvo manual says to use for our temperature we are in.
How does a 40 weight oil produce more soot than a 30 weight oil? Its my understanding, that each brand of oil has their own additives and detergents to suspend this soot?

 

40wt has higher allowance of ZDDP it actually creates higher amount of metallic oxide ash that the DPF cannot burn.

Also, as your soot loading goes up, it increases viscosity of the oil.
If you start with a heavy 40wt and the soot loading starts progressively thickening the oil, it will continue to slow the circulation of oil more and more......

This the big reason for early top end wearout... The ISX Cummins was notorious for this.

However with a 30wt oil and the same soot loading it might only build up to the Viscosity of a NEW 40wt oil when it's ready to be changed.

Higher viscosity = Lower Oil Flow
Lower Viscosity = Higher oil Flow



Your best oil for widest temperature range is going to be FULL Synthetic 5-30 .... The synthetic gives 100°F+ heat protection and also fast circulation in arctic conditions...

 

2013 600k- Weight 70k-Ambient Temp 73
Asked a driver yesterday.
Oil temp hill 242
Oil temp flat is 239- he didn’t wait long to check after the hill.
Coolant on hill will hit 195 (shorter steep hill not mountain passes)
Coolant flat 168
I thought the oil temp was high until I read this thread. The truck is now run with 10w-30 full synthetic. This oil was a recent change. It used to have 15w-40 Dino. It was run that way for years. With these temps it sounds like a good change. The oil pressure is what concerns me now.
Oil pressure flat 80psi. This is the next thread I am searching.

 

Temperature : Ok
Pressure: Should be 30-40 on flat cruise rpm

 

NO, not normal.

 

No , that's actually 100% normal oil temps on all the modern D13 of the last decade.

Semi or full synthetic oils are highly recommended for all the high heat modem emissions motors
