It can be used in diesel engines up to the 2007 model
Marvel Mystery Oil is a fuel additive that can be used in diesel engines. It is added to the fuel at every fill-up, with users generally recommending adding 4 ounces of Marvel Mystery Oil to every 10 gallons of diesel.
It is important to note that Marvel Mystery Oil is only suitable for diesel engines up to the 2007 model year. This is because, from 2006 onwards, diesel fuel transitioned to ultra-low-sulfur diesel (ULSD), with engines designed to run on fuel with no more than 15 parts per million of sulfur. Marvel Mystery Oil contains more than 15 parts per million of sulfur, so using it in 2007 or newer engines would result in fuel with a sulfur content higher than the specified limit.
In older diesel engines, Marvel Mystery Oil can be used as an additive to replace the lubricity lost by the reduction in sulfur content of diesel fuel. It can also be added to the engine oil to enhance lubrication and control sludge, with users recommending replacing 20% of the engine oil with Marvel Mystery Oil at each oil change.
While some users have reported successful use of Marvel Mystery Oil in older diesel engines, others have expressed concerns about its effectiveness and potential negative impacts on modern engines, particularly those with high-pressure common rail injection systems. Some have also questioned the need for additives in modern engines, suggesting that proper maintenance and the use of fresh fuel are more important for engine longevity.
