hossein Posted July 3, 2014 Share Posted July 3, 2014 Hi One Mack driver told me : in low rpm(in 500-600rpm), oil does not reach to turbo bearings( because turbocharger is above the engine) and we always keep engine in 1200rpms.Is this true?Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/36237-e6-engine-rpm/ Share on other sites More sharing options...

gearhead204 Posted July 3, 2014 Share Posted July 3, 2014 5-600 is too low of a idle speed and should be speed up to 650-800 rpm. this will also help oil pressure, but a mack will be one of the least likely engines to have turbo problems as they have a higher oil pressure than some other eng. manufactures.

mrsmackpaul Posted July 3, 2014 Share Posted July 3, 2014 yep gotta agree with Swishy all sounds a bit like BS to me have heard of keep revs up if the motor has idle for a long time to stop it glazing up but Im not sure on that one eitherPaul Quote Link to comment https://www.bigmacktrucks.com/topic/36237-e6-engine-rpm/#findComment-251586 Share on other sites More sharing options...
