What type of motor oil should I use to add to my '02 Chevy Trailblazer. I need to get it changed but I wanted to find out what is best for my vehicle prior to the oil change. I am new to Chevy's and I love mine but she has over 120, 000 miles and I am wanting to find preventative measures. I only need a recomendation on what oil is best and I will go with that. One more thing, would it be considered rude to bring your own oil to a shop instead of using theirs? I wonder if there would be a price change for that.. only curious.
thanks!!!
thanks!!!
