I just got back from a 4 hour round trip drive and I got a "check oil level" notification on my dash. I checked the oil and the dipstick came up bone dry. Not a single drop of oil. I then poured about 6 quarts into the fill tube and checked again and it was half an inch above the full mark. I would have thought that if it was dry, 6 wouldn't fill it up all the way since the engine takes 10 quarts. The odd and scary thing for me is that I haven't seen any unusual smoke, I believe I am correct in assuming a little white smoke is normal with cold starts, right? The oil filter and the drain plug are both dry and there's no oil under the truck, so where did it all go? This engine also has 4,000 miles on it and in the 3 oil changes I have done, 10 quarts have gone in and right about 10 quarts have come out. I am very confused
I believe the dipstick only measures 2 quarts of oil, so on a 10 quart pan, you could be 2 quarts low and the dipstick would be dry. since your now over the line by about 2 quarts, and your dipstick only reads 2 quarts, you were only 4 quarts low, not 6, which is still quite a lot but maybe helps explain why things are not adding up right.
Some white smoke is normal at startup, especially in the cold, however white smoke would not be oil burning, its water vapor (steam) and possibly raw diesel if you were to have an LB7. smoke from burning oil is bluish black due to the incomplete combustion of the oil.
When you say it only has 4K on it and 3 changes, are you saying the oil has been changed 3 times in 4K miles? if thats the case, no way the oils that low naturally, someone filled to gas truck capacity or something silly like that.
I am curious how come 3 oil changes in 4000 miles? who is doing the changes, I think you need to get a hands on personal grip on this trucks service if you are not , if you are doing this yourself then follow the plan on oil in water /water in oil ect as advised in posts. Let us know whats up?
Thats not that strange if its a brand new, or newly built engine. Run it for 100-500 miles, then drain and fill, run it another 1K or so and drain / refill, then another change around the 3-4K mark. I know people who like to break engines in that way. Personally i see no issue with it, probably a waste of oil on the second change, but 40 bucks of oil is nothing compared to a new engine so to each there own.
