I have generation 1 Toyota Tundra with the 4.7 liter engine and relatively low miles for the age. I did an oil change in November using M1 5w30 high mileage full synthetic. The oil I drained looked like typical 11 month old oil, it had 800 miles of use. The oil filter I removed was about 18 months and 1100 miles. The truck runs strong, with no abnormal issues. Probably unrelated but I did recently notice I had a hose disconnect on the top of the engine, causing a puffing noise. Drove that way for maybe 50 miles, until I noticed and reconnected it.
Anyway, today doing some general maintenance, I noticed my oil on the dipstick was at the bottom mark, and my oil cap had a film of milky white on the underside. I looked down into the fill tube and see a little milky oil. This is very upsetting. I was about to go on a long drive. The oil has probably less than 100 miles on it, but it's been all in town and short trips, although it does get to operating temps each time. I have short tripped this truck a bit recently given the cold weather and it's 1 of my winter trucks. We had very cold wet weather here.
2 questions.
1. Since this is my first seeing this, is it safe to attribute it to the very cold wet weather we've had recently. Will this cook off with a nice long highway drive?
2. Unless it's not necessary I'm going to go out now and dump the oil, fill it, dump it again, and change the filter and replace with fresh. Is that a reasonable or prudent plan of action?
Thanks for any sound input, while I go gather my oil change materials and tools.
