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