My choice would be one of the Diesel specific oils. I am a synthetic guy and
I also favor the Mobil 5w-40 truck oil or Delvac 1. Equals are Shell Rotella
or Chevron Delo. Castrol and others have Diesel specific oils. Regular oils
of this type will usually be a 15w-50. The synthetics at 5w-40 offer cold
weather starting and fuel economy advantages. Oil change intervals are best
determined by oil testing. Soot is the major contaminant. Good filtration is
the solution.

Subject: Diesel Oil?

Greetings all - What's everyone's favorite oil for 1982 1.6l Diesel Engine
Westie?

Last time I looked, a 15-40 diesel weighted oil did the trick. Synthetic or
Standard Oil?  Thoughts, opinions, snide remarks?

Thanks in advance,
