Manual says 3K miles severe (I qualify, leadfoot) 4.8K miles normal I use good syns and filters as per sig for Hyundai at ~4K.
3,000 mile paranoia. Who has it here?

I change mine at 3000, its new and the manual states for severe driving which I do see, short trips under a mile everyday to work and only on the weekends does it see the highway so I do only 3000 mile changes. I also use synthetic with an OEM Hyundai filter for warranty reasons.
Oil changes are cheaper then failed ca smog tests and ticking parts and buying a new car.
My car has 140k, so I change my oil every 2500 miles.
Feed and water your horse liberally.
Oil is not an actual mechanical part, and is an oil, not a solid, and will perish with heat. especially with today's little hot running aluminium engines. My engine works very hard for me and sits at stoplights all day in searing heat, therefore every couple of months it gets fresh oil&filter. If I had a brand new car and only kept my cars for 100k, (leased or traded in) then it's not really my car, and I could be cheap about maintenance, but I have always owned used cars (10-20 years) and know what happens when they don't get frequent maintenance.

You know, if it is your heart felt belief that short changes work for you then I say go for it. Might be worth the peace of mind.

I used to have the 3,000 mile paranoia when I relied strictly on $19.99 coupon oil change special coupons. Even then, this OCI probably was not justified. I'd be surprised if the bulk Pennzoil, Mobil Special or whatever CarX or Midas used would not work well until 5,000 under normal usage patterns.
Our MDX sees a lots of short trip in winter, and I always rush to change it out as soon as the spring arrived, so the car get fresh oil in late Nov or early Dec, and stay there to March or April of following year, sometimes mid 5000km, which is just a little over 3000miles.
I used to do 3K and now I do about 6K (miles)
Oil has also gotten better too though, especially if youre just running conventional.

Gave up any paranoia I might have had about 1991. No issues to date, so life is good.
Checked my trip odometer for oil changes and it read 3,500 mi. I do have a 5,000mi/6month paranoia though. I'm getting a UOA done on that though.
I am only 1/2 paranoid i change at 6k.
I have noticed lots of guys here seem to have 1 year paranoia...

Im with you on this, i have no doubts that our modern oils can far and away last past 3,000 miles.. my problem is contamination, filter endurance/bypass valve, fuel dilution..
id rather change it sooner and put the odds in my favor..
I run synthetics and i do severe duty in one truck, it doesnt go past 5K my wifes Honda gets syn as well, and i try and catch it between 4,500 and 5,500 are these oil's worn out ? doubtfull, am i paying $20.00 a pop for UOA's ? Nope, Hve i before ? Yep, when i was running dino, then i thought to myself "you dope, your paying more for UOA's than you are for your oil and filter".. i stopped. I sleep fine with 5 thousand mile OCI'S

So I have something for you 3,000 mile folks. Kendall started the 2,000 mile oil in 1928. You mean to tell me that in 84 years of progress PCMO's could not be engineered to handle a OCI longer than 3K.

If I do mostly highway mileage on a vehicle I'll run it over the 1 year mark as long as the miles are still reasonable for that oil. Back in December of 2004 I posted my BIL's UOA from a 1999 Porsche Boxter he bought from the original owner. It was run as a fun car on the back roads of rural NJ. It was always put away hot. I believe with ~9,000 miles on the factory fill of Mobil 1 5W-40 in those ~5 years the UOA came back still good according to Terry Dyson. I think a lot of time it's how the vehicle is run and the quality of it's oil. Some can do it, some can't.

I always think of that UOA + the 4.5 year Corvette UOA when that topic comes up.
Not to mention the fact that Porsche's standard OCI is 2 years.
I generally am willing to go up to 3 years on low mileage cars. I felt completely safe going 2000 miles in 36 months running Rotella T 10W30 in the 440 TNT in my 1968 Chrysler 300.
