I just started using yesterday DELVAC 1 for my 87 300 td wagon, it has 187,000 miles on it. I accidentally put in about a quart too much, will it do any harm?
Also, when should i do the FIRST oil change and subsequent oil changes?
And lastly, i got the analysis kit, when should i do it? at the end of this next oil change or wait for the next one after?
thank you
