You will never catch me running 25,000 miles on 1 oil change.
How many times do you change your filter during this 25,000 mile period?
Thats the biggest issue is filtering out the oil.
I know oil can last up to a year and not break down and amsoil can probably be used for 25,000 miles but you should be changing your filter every 5 k or so and topping off your oil.

 

Every 3000 miles. Religiously. Mobil 1 and WIX filter. I put 3k on it about every 2 months....

 

I change mine anywhere from 3-4k miles. And I use a semi-synthetic blend oil with a Mopar Filter.

 

holy hell 25,000 miles on an oil change! I'm impressed. That's got to be saving you money right and left

 

i was quoting pavement-hater that said they were going 25k on an oil change

 

25k on an oil change. Do you rotate your tires inbetween oil changes at every 6k? Do you replace the filter every so often?

I thought I read somewhere that using Aimsoil they are ''good'' for 25k but they recommend changing the filter (Aimsoil filter) every 7-8k miles.

 

Mobil 1 Synthetic 10W30, wix filter.

Oil is changed every 15,000, filter is changed every 5K with a quart added and a tire rotation done, plus a grease job. Frackin' oil is expensive.

 

Amsoil used to say change filter every 6 months. Now they have extended service filters that last 25k.

 

Every 6months, whichever comes first. I change it in the fall and in the spring. Mobil 1 Full Syn and Mopar Oil Filter.

 

Extended periods, sure... but I'd never run anything near the 25k mark. I change mine 5k-6k. The wife's is changed every 5k or a tad more, and thats when I change mine as well (she has the service reminder setup in her overhead console). By the time she has 5k, I usually have 5.5k-6k.
