CAT DEO 5w40 Synthetic

[Bill Plock]

Anyone have experience with CAT DEO 5w-40 Synthetic? I heard it is DELVAC-1 in a CAT jug. I 'm considering using it in my Duramax Diesel since it's readily available and a little cheaper than DELVAC-1 where I live. The data sheet on the CAT website looks good and it also implies API certification (shows the round API license LOGO). However, I can't find CAT DEO 5w40 Synthetic listed on the API license website (?).

Bill,

The Cat 5W40 full syn, Part#141-3339 is the same as the Delvac I as you indicated. I think they add a tracer of one element, can't remember, to distinguish it from the Delvac. I can't help on the API, but check with your dealer.

Delvac 1 and the CAT syn are indeed one in the same; same for API classification: Delvac 1..
