Anyone familar with Royal Purple synthetic oil? - Toyota Yaris Forums

Enos is a overpriced in my opinion. It has a shitty TBN which wont matter if you change your oil every 3000 miles. Its also full of moly because the new enviro oils cant use zinc based extreme pressure additives (which work very well). if your driving hard or in hot climates the viscosity at 100c is light enough it may increase engine wear. If you must go with a JDM oil get the right viscosity grade! Sure your mileage may go up .02 mpg for every 10 weight you go down but your engine will pay the price!
