Originally I was thinking that DI made power in a narrower power band and was therefore more sensitive to running at high speeds.
Then I had to reconsider because of the 6.2 being IDI but IIRC yours is a 1ton truck and probably geared for stump pulling. I'll make an educated guess (I think you'd mentioned it once) that the engine is wailing at 65mph... When I had my '85 190D I did a bunch of experiments and could never find a difference in mileage between 4th and 5th. Meaning I'd commute 400 miles never using 5th and then the next 400 miles using 5th as I normally would. That car averaged 38mpg no matter what. That said I was keeping the speed moderate. I suspect if I was at 90mph the difference would become apparent. -Curt Date: Mon, 2 Sep 2013 02:49:44 -0400 From: Michael Canfield <slozuk...@gmail.com> To: Mercedes Discussion List <mercedes@okiebenz.com> Subject: Re: [MBZ] my kinda car Message-ID: <CALHJ_1DihQvnAfAhCbp1WWZ=mbdva_qu0mq929rxbxnopjn...@mail.gmail.com> Content-Type: text/plain; charset=ISO-8859-1 6.2 is idi......Powerstroke is DI. Benz is idi. What are you getting at?
