Hi, I was searching around and somehow found my way here...very informational but now it's spurred me to have more questions, thus the post.
Anyway long story short. I just got my first car from the mechanic three days ago and the vitals are...
1994 Buick Century 3.1L V6
63K miles
One owner, old lady
Came to me w/o most recent oil change sticker so I have no clue how it was maintained, I figure not so well, although it does have new brakes and apparently "good" trans fluid (According to Monro who said don't waste my money to change it)
So I have a few questions:
A.) I'm about 1/4 way through my 1st tank of gas and I put Chevron Techron in it, it idles pretty rough, should I do another run or maybe try redline? Also I had to get the EGR Valve serviced the day I got it, should I check the PCV Valve?
B.) My Mech changed the oil with 3rd party 5W-20, can I honestly help myself out by maybe changing my oil over to maxlife or M1 clean?
C.) Any car care tips you can give to extend the life of my car (looking for about 30K out of it)
Thanks again.
