Is the temperature swing while driving at higher speeds? Have you replaced the lower radiator hose and did the replacement hose come with an internal spring?

Get a new mechanic? Have you checked all the old vacuum lines/hoses and cap for leakage? By the way, welcome to the forum!

Hmmm? I once drove an old cube van for work. It used so much oil that we routinely stopped at a gas station to fill it up with oil and checked the gasoline!
