I just bought my first diesel a 1993 GMC 6.2 liter. I know this may be dumb question and maybe it's been covered before but can I use a 2 stroke mixture in my truck? Also how often would you recommend changing the oil on the motor and the fuel filter? Thanks for your input gentlemen. Grant.

Standard interval as usual... 2 cycle oil doesn't effect either the engine oil or the fuel filter changes...But use the standard 128:1 ratio. ! oz of oil to 1 gallon of fuel... :thumbsup
