Guess its time for an overhead to be done on my C-16!!!

once you figure out the problem, run rotella full synthetic. the bypass filter let's you push out your oil drains far enough to make synthetic very cost effective.

 

Very valid point here. But, if I may add something... if you (or anyone for that fact) is looking at extended drain intervals, oil samples are even more vitally important. Id start with taking a sample slightly before my normal drain marker (I.e.12-15k) and send it in with a note asking them to check the feasibility of extending your drain interval, and then cintinue to send in samples every 5-10k. The TBN is a very important number to pay attention to when looking to increase your intervals.

Bypass filters do a great job of removing suspended particulates in the oil, but to my knowledge, they dont replace the additives in the oil and theres no way to replenish the TBN. Which is why thats such an important number to watch on your sample reports.

 

Also, make sure you note that you added a gallon of Lucas when you send in your sample. The report will probably show numbers that arent 100% accurate due ti the additive, but as long ss the lab knows its in the oil, they can try and normalize the report to take that in account.

 

I prefer my Rotella to be UNstable - sorry Mr. Lucas!

 

Would that be because you might be a little unstable yourself?

 

@Whitey14243 what gives I read three pages of a thread waiting to see what the green tint was and you never come back on to tell what happened I get this is late but come on man
