DT466e question about oil
Hi everyone! I recently purchased a 40-foot International RE3000 with a 7.6L Navistar DT466e Diesel engine and an automatic Allison MD3060 transmission. I drove it 2400 miles to get it home, and I noticed that the bus chugs through the oil really, really quickly. I know it's a HEUI injector system, but to my knowledge, it should last at least 500ish miles before needing to have oil added. Mine goes about 250-300 miles before needing more oil.
The bus has no leakage anywhere on the ground, so I'm wondering if the oil could be leaking into the engine or something? Is that possible? The smoke is clear to the oil isn't burning. I'm really confused by this.
I appreciate any help in advance! Thank you so much!
