Delo 400 every 5000 miles or 6 months, this goes for all my vehicles including the motorcycle and genset. Only the Accord gets Mobil-I as it has been like that since the very beginning.

I have 5w-40 synthetic in the 300D. I forget the brand. The bottles were blue.

In the 240D I have 15w-40 Delo. Considering the temperatures we've had here lately, I think I should have gone with the 5w-40 when I changed the oil last.

83 300D Turbo with manual conversion, early W126 vented front rotors and H4 headlights 400,xxx miles

88 Jaguar XJS V12 94,xxx miles. Work in progress.

If you are not getting any starting problems, stick with Delo 400 or switch to Delvac-1 or Delo synthetic for winters.
