    Not necessarily. That depends on the exact oil used.
    Some turns very dark after only a few miles.
    Mobil 1 is known for that, just for instance.

    Oil gets dark, yes from blowby. And from the detergent additives.

    Clean oil is always better than dark and dirty oil. Toyota went to 10k oil changes on the Prius. Some manufacturers in the past went to 7.5k, and have since cut back to 5. Nissan still uses 5k.

    Any manufacturer going to less than 5k would be criticized by the competition. That's why the so called experts say that the old 3k oil change of yesteryear is a thing of the past. They just won't tell you that the engine will last longer with clean oil.

    I recently saw Walmart brand 0w20 for $16 the five quart bottle.

    I don’t know what oil the seller used in my wife’s Edge just before we bought it, but it was black as the Ace of Spades the day after we drove it home. And it had 7 miles on it according to their tag. I made them change it again. I threatened to return it on their 3 day return policy. I don’t believe they actually changed it, as it’s still pretty clean 45 days later.

    If you choose to reuse your Gen 3 head or source a reman one, it is a direct bolt on to the Gen 4 short block.

    Did you make any other changes? How much is the Prius burning using those oils? Are they synthetic or dino oils?
