Do I need TBN on my oil analysis? 8,275 miles 15 months, syn and bypass.

I run rotella syn 5/40 and it has been in there for 8,275 miles and 15 months. I have a sample ready to go off to blackstone. I have run this many miles but I have never had oil in there this long. I want to make sure I am ok to do this. What is the value of going with the TBN testing?

I have run regular old Rotella dino oil that long.

TBN is one of if not the single most important thing to test oil for. TBN stands for Total Base Number and is an indication of how much alkaline reserve is in the oil. Alkaline reserve gives the oil the ability to neutralize acidic conditions in the engine and prevent corrosion.

The base number will give you an indication of how much reserve is in the oil and ultimately how much life is left in the oil before it turns too acidic.

Blackstone will comment on the what you get for a base number and how far you can go with the oil.

I always get a TBN done and will continue to push the oil change longer mainly based on the TBN.
