Coolant constantly dropping but no external coolant leaks.
New oil change of 5w-30 at 105,470 miles. I am only around about 106,800 miles and engine oil is very black and sludgy.
I was told viscosity is too old due to being an older truck and to use higher viscosity 10-40. So i did.
in terms of overheating problems or issues, none!
Removed spark plugs and passenger side plug #8 was drenched in oil. All other plugs looked very burnt with some oil.
