HeyCharger Posted January 26, 2007 Share Posted January 26, 2007 Hi guys. As most of you know, I've just replaced my 673P with a "C" motor (ENDT673).As this is obviously a turbo, someone has suggested that the engine oil may have to be a different grade/type because of the turbo.Comments please.Thanks.

kevin mccune Posted January 27, 2007 Share Posted January 27, 2007 Try Rotella T or the MOBIL OIL' Cat 'uses in 15-40w-we had very good luck with 'Cats 'Mobil sometimes never having to add any between changes on a tight E7. Kevin Quote Link to comment Share on other sites More sharing options...

bulldoggin' Posted January 28, 2007 Share Posted January 28, 2007 Rotella would be your best oil. Quote KEEP THE BLACK SMOKE ROLLIN Link to comment Share on other sites More sharing options...
Speed Posted February 12, 2007 Share Posted February 12, 2007 Rotella would be your best oil. I don't wanna hijack this thread,just borrow it for a minute. Is the Rotella 15/40 good for the Mack gas engines too? Thanks!
