How will Delvac 1 affect my oil consumption?
Our experience — and that of many of the fleets and owner operators currently using Mobil Delvac 1 — is that oil consumption decreases. The synthesized base stock in Delvac 1 is much more stable and consistent versus conventional base stocks that have a broader mix of petroleum components. The combination of resistance to oxidation and reduced evaporation at high temperatures, as well as the consistency of the synthetic base stock, results in less oil being consumed. Be aware, however, that if your engine burns oil today due to a mechanical condition, Mobil Delvac 1 will also probably experience high oil consumption. There is no substitute for fixing mechanical problems.
