Just purchased new 2015 C class Ford gas E450. In that it's been sitting over one year, do you recommend an oil change? Have read that oil can gain condensation. Thank's, Mike in Utah
I would check the level and go camping. First change at 5,000 miles or longer if the book calls for it. As long as you are not making half mile trips to the grocery every day I would change on mileage only.
Send in a sample if concerned. Never read a post where tested oil was over due full of condensation and acid build up.
