    I just bought and 85 blazer with a rebuilt 350. It's got about 17K on the rebuild. I need to do an oil change so I just have an easy question. What oil should I use? I put 5w-30 in my 2000 f-150, should I use the same, or 10w-40 or what?

    I'm going to be using this as a daily driver.

    Thanks for the help.

    With only 17k on the motor I'd start using a synthetic oil. And use a good quality filter too, like a Wix. Don't use those cheap Fram filters.

    I prefer Valvoline, and I've always used 10W-30.

    I'm not sold on synthetic yet. My engine builder recommended using regular oil and changing it every 2000miles.

    Dont use 10-40. 10-30 if fine or 5-30 if it gets real cold where you are at. I guess synthetic oils are good if you want to spend a bunch of money every time you change oil.
    I use them in my boat and in a car I have a Turbo on. But for my Daily drivers I like regular 10-30. I just cant see how syn oils costs are worth the small benifits they give.
    Wix, Purloator, or AC delco, are all very good filters. Fram sucks.

    You might also think about doing a trans fluid change/filter. Espically if you have a 700r4.
