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 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 Share on other sites More sharing options...
