Sorry to be a dick but this is kind of a terrible poll. The 3 most common intervals are 3k, 5k, and 10k. One is not represented. One is represented by 2 different options and 2 of them are represented by the same option.

That’s kind of a personal question.

I have to change annually as I don’t do the mileage, If I did a 6k change on my Skyline it would be every 10 years… LOL. I use my T3 a lot more but still can’t get anywhere near the distance, So once a year at some point (Usually just after an MOT) I just service them.

I drive an EV now. Where’s the ‘never’ option?

Yearly, regardless of mileage.

I work at a shop so an oil change costs me like 6$. The answer is way too often.

Yearly on my mustang. Never put more than 5k miles a year on it. Gti gets it every 10k, or yearly. Might drop the interval now that it’s mostly city driving.

Every 3,000-3,750 miles. HyunKia GDI 4-cylinders are dirty little engines and the “severe” schedule of 3,000 (2.0T), 3,750 (2.4L/3.3L) applies in “rare” driving conditions such traffic in hot weather, very cold weather, hills, <5 mile trips, stop/go traffic, etc.

Your intervals are sadly too wide by the way.

At 20%

Depends on the car. My subaru says every 6,000. I bought it new so I just do it every 5k for easy record keeping.

I have 20k on my trucks built up engine. I religiously change it at or before 3k.

Mobile one synthetic and filter for everything since it parked in my driveway.

Minimum every 6 months during the half yearly service. Otherwise, according to the specified mileage on the bottle.

Once a year with amsoil or the like. Cars average 5k to 10k miles a year.

I drive a VW, besides the filter it changes it’s own oil

I don’t even own a car to do oil change in the first place, lol.
