TestOil's customer service is outstanding! I have been doing this for about 30 years and there are only three companies I have ever come across that deliver what they say they're going to do and TestOil is one of them. When we first started using TestOil you weren't the cheapest, but to me, that didn't matter. I get what I pay for. You guys are light-years ahead of everybody else in terms of service and delivering what you promise.
