Introducing TBN wipes developed by Lake Speed Jr. at Driven Oil.
Now we have a instant test for evaluating the condition of the oil and if it's time to change it yet. Easy to use, the paper changes color when the TBN (total base number) is low, indicating the detergents and dispersant package is all used up.
Ideal for those running Driven XP9 race oil - you can now pull the filter, test the oil, and put a new filter in. Change the oil now only when it's really needed. No need to guess or wait for the lab to tell you the result when you can have it in seconds. For less than $5.
