After I change the oil in my 17 Tundra, my dipstick usually shows around 7/8 towards the full mark, and shortly after my 45,000 mile change, it also showed somewhere around the 7/8 mark after a new Toyota filter and 8 quarts of Mobil 1 (I even tried to get every drop out of the Mobil 1 containers to see if I could get it closer to the full level), now at around 46,200 miles my oil level is right at the full level. The manual states to wait at least 5 minutes after shutting the vehicle off before checking the level. I've found my best readings are 15 min after shut down or after sitting overnight. Each time I check it, I'm in my garage on level ground. My coolant level appears unchanged since oil change, there is no noticeable smell of fuel on the dipstick, and overall the oil appears perfectly normal. Is it possible for several ounces of oil to get suspended somewhere or hung up and then released at the next drive? I've never sent in a sample to Blackstone, but I've ordered one this time. Anyone else ever experienced any unexplained oil level fluctuation like this?
