[QUOTE="MossBack, post: 625537, member: 2326"] The oil is warrantied to 25k miles or 1 year not just promised. The fact is you need to do oil samples at anything past 5,000. For me I barely do 10,000 a year but I still will perform samples for peace of mind. The HUEI system is tough on oil period! I always recommend a sample with a TBN read out because the shear will put it down to a 30 wt. very quick. Go to AMSOIL and read the study about the medium duty international garbage truck testing that they performed. And I would even say go to black stone or another 3rd party testing lab. AMSOIL uses oil analysis and it costs a little less. Just be sure to send a clean sample along with your oil for comparison. And if science isn't good enough then don't buy AMSOIL and use delo 400. And Fram filters! [/QUOTE]
