How does Mobil Delvac 1 compare to competitive products?
There are many new entries in the synthetic and partial-synthetic commercial engine oil market. But they have a tough time matching the 20 years of experience we have with field performance of synthetics in diesel engines. You can be assured that Mobil Delvac 1 not only works with the latest engines, but also performs in all of the four-stroke diesel engines that have been manufactured over the past 20 years. And, all of the evaluations we have performed on competitive products over the years have not yet identified an oil that can match the performance of Mobil Delvac 1.
