Synthetic oils are best.... But pricey. I have experimented with different brands of synthetic oils in my DeLorean for the last nine and half years. I have over 102,000 miles using synthetic oils with no problems and odometer is registering 112,000 plus miles. BTW, I also have synthetic gear oil in my manual tranny with major differences in the tranny operations. It is smoother and quicker especially in the extreme cold winter and with no "dino petro" smell in the hot summer temperature as with the conventional dino petro gear oils.
