My dad has always been a "change your oil every 3,000 miles regardless of what new cars/dealerships say" most newer cars say to change every 5,000 or 10,000 miles. I just wanted to get the texags opinion on this.

Mobil One at 10,000 or every 12 months for me

Edit: Toyota products

So was my old man.

But, his dumb-assed kid (A/K/A me) lets it slide 'till five.

Whenever the vehicle or service manual says to do it.

When my car says to. Which is usually 10k miles.

I wish they would move to an engine hour rating and we could change off of that schedule.

Oil is cheap insurance.

Highlander says 10k, I do 7.5k.
Mazda6 says 7.5k, I do 6k.

Mobile 1
Tundra
Manual says 7,500
I usually do it a little before

273,000 miles thus far. It's working

Every 6,000 on the wife's vehicle

Whenever the oil life percentage gets in the 5%-10% range on the boy's car

Every 5,000

Every 3 thousand on my 75 Chevy C10.
Every 5 thousand on the Mercedes.

I don't think it makes that much difference whether you do 3,000 5,000 7,500 if you don't plan to keep the vehicle past 200K miles.

I've had vehicles have zero issues doing every 7,500. But then I've had vehicles have issues doing it every 3,000.

2019 F150 2.7 every 5k

7k. Sending a sample to Blackstone next go round, to see what they recommend.

I do every 6k on our Subaru with Mobile One oil and filter
On my 6.6 gas Chevy Mobil One oil and filter when the truck says so. Probably every 7500 or so. But I drive 40k/yr so I never worry about time between I'm always on mileage.
Our Trans Am gets it twice a year if it needs it or not.

I buy cases of mobile one when Costco puts it on sale and stock up. And filters by the half dozen from rock auto.

I am the same way. I was raised on the 3k rule and I followed this rule until the oil i was draining out was still fairly clean. I change oil every 5k now.

I don't drive all that much since I work from home, so I change it each year.

Typically at 30% of oil life indicator. Also use the documented viscosity as cam phasers require the low end.

As someone stated, cheap insurance.

Also change my auto transmission fluid at 30k miles.

I do a change every 5k miles on all of our vehicles as it is simple to remember.

My car: Mobil 1 and a top Fran filter every 7500 miles. My old truck went 165k and still was running perfect on this schedule when it met it's untimely demise.

Wife's van: Whatever synthetic is on sale at Walmart when the computer shows 15% and a top Fran filter. Pennzoil Platinum when I changed I a couple weeks ago.

Used to go to NTB to get oil changed on both van and my previous vehicle, but my previous vehicle started having issues with oil pressure at 160k, and what I thought was an oil leak on my wife's van ended up being them not making sure the seal from the previous filter came off. So, new car for me and I decided to start doing it myself again. Rotate the tires while the oil is draining.

Generally on weekends.

Every 6 months which is approximately 2.5k miles on a 2019 Hyundai Sante Fe Turbo. Oil changes are done at the dealer which is easy since they are open on Saturday mornings.

1Ags says that i need to change my oil on the "harsh" schedule because mostly I only drive 1 or 2 miles to grocery / work. This means I am also hard on batteries.

Fran

Ffffffuuuuuuuuuuuuuuuuu…..

Both of our Toyotas call for full synthetic every 10,000 miles. I stick to that rigorously. I trust the Toyota engineers.

First, depends on type of oil vis-grade required = newer cars are calling for 0W which is synthetic in its base oil hence longer drain interval

Second, depends on if purchasing synthetic oil or conventional oil = to see if can extend drain interval or not (synthetic doesn't breakdown as fast as conventional)

Third, brand matters versus non-brand = due to additives purchased and blended to support longer drains

Subaru Ascent every 6K or 6 months. My wife doesn't drive much so I just figure twice a year.

Ram 1500 shows every 10K. That would be longer than any other vehicle I've had so I'll prob do one at 7500

5k miles and Kirkland brand oil. Manufacturer says it can go 10k but the oil maintenance light goes off every 5k

Mobil1 and wix filter when the oil life indicator gets to 10% (gm)

Whenever I get below 10% which is about once per year. I only put about 5k miles per year on my car.

Mobile One whenever the car cries for help.

1, No less than once a year regardless of anything else.
2. When the manual says.
3. For conventional or a blend, at 5K.
4. For synthetic, at 7.5k.

3 and 4 are rules of thumb and not absolutes but I've followed them on all my vehicles since the '90s and haven't had any oil/engine related issues. I favor synthetic but my F150 says Motorcraft blend, so that is what I go with.

Regardless of the "cheap insurance" argument, 3K is ridiculously too often. Unless you're driving in a very rough environment that would suggest you need frequent oil changes, 5K is more than sufficient. Synthetic can easily go 10K but many filters would struggle to reach that, hence the 7.5. If you've found one that can, I don't see any reason why 10K is out of the question.

5K intervals. Except for garage queens. They are annual.

Our Tundra is annual. All highway miles and less than 3k/year.

Shouldn't NA vs turbo engines be more of a deciding factor? Many drivers rely on blackstone (which is a horrible idea unless you're looking for contamination) to tell them that 10k or even 7k is kosher. Realistically the only time that is acceptable is with an NA engine traveling highway miles.
