DD15 engine eating one gallon of oil for every 5000-6000 mile, Please advise.. :(

If I had a propensity for using a 40w in the newer engines, I would prefer a 5w40, mostly because I live and primarily operate in the northern tier of the country. 15w40 in the winter here can be like molasses at start up. Of course, at operating temperature, they are the same viscosity. A 5w40 would cover the bases a little better than a 15w40.

While I did use 10w30 in my S60 for a while, it was out of the prodding of my oil supplier to try it. Oil samples were fine, but I now use a 5w40 in the winter months and 15w40 in the summer months.

 

I think all components of newer engines are made in oriental countries without quality control. few days a go I saw a camshaft from ghg14 with lose cams on it..

 

Yeah the cam lobes are pressed on and very easy to spin them out of alignment with a simple over speed condition.

 

have you seen any problems with geartrains on epa07/10 ?

 

Nothing so far. Just a simple air compressor locking which wouldn't turn the engine over. I think the geartrain is pretty strong on the DD. I seen a few series 60 gears broken and dropped valves from improper timing from the last person that reassembled it.

 

Don't have a DD15, but that is good to know if I were in the market to get one.
