    Can I safely change oil at 6K interval with conventional oil ? Manual says 5K but I read somewhere it was 7.5K earlier. I have a 2007 model.

    What do PC members say ?

    If 6K then, can I just ignore the maintenance light once that turns ON after 5K ? or is there a setting to default it to 6K so the light doesn't turn ON?

    Why not just do it at 5k? Yes it's safe

    Agreed, it is safe. It was changed from 7500 because of lawyers and the sludge problem in some Toyotas in the early 2000's.

    If you're under warranty go with 5k.

    I'm not sure the correlation between conventional vs synthetic oil and oil change interval is that clear. Does Toyota actually say anywhere that conventional oil alters the oil change interval? I appreciate manufacturers of synthetic oil tout it's ability to have longer change interval, but what does Toyota actually spell out?

    because as an idiot - I didn't pay attention to my dash to see the maintenance light has been ON for over a week and I have driven almost 1k above and beyond the 5k oil change interval limit.

    I plan on getting oil change done later this evening.

    No warranty here - Prius has almost 150K miles on it.

    If you are driving a over 1000 miles in a little over a week, then I'd definitely error on the side of changing it more often and sooner as opposed to less often and waiting longer.

    If I was putting that many miles on a vehicle that rapidly, I'd change to synthetic.

    why not synthetic? then you need to do it every 10k. Price for materials x2 conventional will be about the same as x1 synthetic

    no problem with 6k. no way to change the 5k default, but i think there is a maint. menu in the mfd that you can set for 6k reminder.

    I doubt even 9k miles matters at 150k miles. I change my 2005 somewhere between 10k and 14k miles but I use Mobil 1 oil and filter. It also is now kinda self changing since it uses a quart every 3000 miles. It really changes itself every 12k. I just drop it, install a new filter, and refill.
