Engine oil OEM Honda or OEM Audi

8k miles is just fine. I did that the entire time I've had multiple cars and they have gone a great distance:

I use my 09 Fit as a courier vehicle. I've driven over 80,000 miles in 14 months. If I did oil changes every 5k miles, I'd be under the car every 3 weeks.

I just follow the maintenance minder, which works out to 10k miles, give or take, but I've done that over all the 175,000 miles I've put on it in 10 years. I use Castrol GTX high mileage, but I'm sure it doesn't make much difference. I've seen a lot of stuff saying Walmart Supertech is probably just as good,if not better than name brand oils.

I do my own valve adjustments, and the inside of the engine is nice and clean...

I drive my car pretty hard, so 5k is preferred for me.

I change mine every 5K.

Worth the piece of mind to me considering it a turbo engine.

I do mine every 5k. It maybe adds one extra oil change a year for me, if that.

I've always put Honda GN4 in mine and whatever recommended weight stated in your manual :)

I don’t drive my car enough to hit any of the reasonable mileage points. I change my oil yearly, roughly around the time it gets inspected. Might be overkill (last year the car moved 2k miles, the year before was 2.4k), but I figure the $80-85 I pay is worth it. My wife’s Q7 will be getting its oil changed every 5k miles. It’s a 3.0T supercharged and they love to eat oil, I’d probably add half the oil back just to make it to 10k.

I do every 5k (2013 S4)

I just change it every 3k as a maintenance think no one told me to. I'm just afraid of messing up my turbo if I waited to long.

2012 3.0tfsi turned out to be a mild hybrid as it burns 1l/5k km.
