Any T680 Owners? Would love some feedback.

True...there 2 fleetguard oil filters recomended

FS 9080 from factory....30 microns
FS 9031 high efficiency heavy duty long life seal....15 microns

I'll see but will put one.....
Right now i put rottella T5 10w 30
Next ill do Delo 5w-40 full with the cleaner.if engine will like it

 

No, I have never had before. I choose it because cheaper and simpler to maintain. Also I think it does a better job, because it can filter out any particle what is heavier than the oil. Includes corrosive acids, silicon and water. Also for excessive wear you do not have to have large particles. Think about sand paper. I do not mean the FS2500 is bad or useless, it helps to keep your oil significantly cleaner than the engine oil filter. Just these were my thoughts.

 

SPN 157 FMI 18 low fuel rail pressure.

Update:
filter was clogged. Stupid me.

 

Hey, behave. I would hate to hear any trouble.
I am happy it was an easy fix for you.

 

not so easy though. $40 primary filter (clogged, first time changed),




$63 secondary filter (changed on 10,000mi), labor $300, lost all day.






Its rainy today, roof marker lights are still leaking. Cab panels behind passenger door are leaking too. Water drop right to my swivel table. Quality Control on Paccar really sucks.

 

Lol. Best piece on the market.

 

I wonder how is it possible to do such unacceptable QC.

 

Wow. My 06 VN780 Volvo sleeper started sagging and letting in some water, though under the sleeper in a very heavy rain when parked. That was in my last year of ownership. Truck was 8 years old. I hope the classic cabs are still made tough in KW. I haven't heard any complains about them so far. I'm going with the T800 in a few months.

 

Here we go, second probe.



Overall there are improved all wear components (iron, copper), contaminants. New oil also demonstrates higher rates of additives (Magnesium, Molybdenum, Boron). New oil also has higher viscosity (even after 10,000 miles!), which though corresponds with oil viscosity index (5W-40).
Bad sign is that Soot % also increased. I'll watch after it.

 

Why do you wish 3.91 rear ratio?
