What's going on guys, hope everyone had a great break. I'm sure everyone knows about the L33 engine and its oil thirst, but I have yet to find a way to noticeably slow it down. I've tried engine flushes and everything in between with no success. Now I've read somewhere that someone said screw it and started using diesel grade oil in their engine. I mean on paper I guess it'll work since it's thicker but I'm not sure about the technical side. The last time I changed my oil, I reset Trip B to count the miles before my check engine light comes on. I checked the dipstick at 1K miles and it was already at the lower end of the checkered pattern. At 2K miles, I checked it again and it was even with the very bottom line of the checkered pattern. Now at 2,436 miles, the "check oil level" light came on. It's been the same story since I got it back in March 2013 but I've just been putting up with it. Now I'm looking for ways to slow it down and I have been told by many that it's just how these engines are made and that it's tough cookies. There are no signs of oil being burnt, i.e. no smoke or smell, no signs of oil in TB, and the PCV valve is the updated orifice style. Truck is a 2005 Silverado 1500 Vin B 5.3L. Anyone have experience dealing with this or any suggestions on other ways to help this engine from eating its oil? Thanks for any help!
