I have a 2006 Azera with over almost 205k miles. I currently use regular oil as recommended by Hyundai and change it religiously every 3-4k miles.

I drive a lot and continue to rack up the miles (about 1k a week). Should I switch to a high mileage full synthetic oil? Furthermore, I heard I can drive for 8-10k miles on full synthetic between each oil change. Is this true? And if so, would it be okay to do so on a car with almost 205k miles?

Also, is one brand of oil better than others? Any brand I should stay away from?

Thank you in advance!

I recommend valvoline high mileage oil. Don't use full synthetic oil, since it can clean out the 200k miles conventional oil sludge and may have leaking problem in the future. Just use high mileage conventional oil and drive until it dies

If the engine is running fine, no oil leaks and no consumption issues then there is no need to use a HM oil. At 205,000 there is something to be said for if it ain't broke don't fix it. Although a possibility if you switch to synthetic you could develop some oil seepage which then may warrant going to a HM synthetic oil. IMO I would just stick to what you have been doing and just keep driving it.

If you've been doing "regular oil" changes at the dealer, I assume you mean he's been using non-synthetic oil. I would highly recommend AGAINST putting synthetic oil at this point, unless you pulled off a valve cover any physically inspected the gunking condition inside the motor. Now, probably you're Azera is real clean inside that motor, and it would probably be okay to use synthetic High-mileage, but for me, I wouldn't do that unless I was totally sure it would not de-gunk my motor. Standard dino oil can leave gunk in any motor, but the most pristine, after 200k. Synthetic can loosen up gunk in an old car which has never had it, and it can get in the little lifters in the heads, rendering you Azera a beautiful lawn ornament. Seen it here at the forum a couple of times. Standard synthetic oil has a way of finding leaks in old motors also, although again that would probably not be a problem in your nice, clean Azera motor. Synthetic high-Mileage oil will help any potential leaks to seal. If it were my car, I'd have an idea of my gunk situation, and probably use Super-Tech Synthetic High-Mileage oil because it's cheap. I'll probably buy some my next bottle for my collection of bolt-buckets. Good luck!

This, very much, this.
