Just some general knowledge for you guys. The “european” formula oils are nothing more than low SPAsh,SAPS/Ash oil formulas. (They all mean the same thing) Basically means the oil is made with less sulphated ash, phosphorus, and sulphur than traditional oils. This produces less ash and crud in the exhaust system so it doesn’t contribute to clogging dpf, scr, traditional cats, etc. It is called European formula because it was developed by a certain European company that I happen to work for, and first appeared in their diesel vehicles. We are also the ones that gave the world DEF and scr. You can thank us later.
anycase for warranty purposes you can’t use any oils not approved. Outside of that if it’s a synthetic oil, the correct weight, and low spash or “European” formula, it will be ok to run in your diesel. Comes down to personal preference at this point.
