I have religiously changed my oil every 3k miles...I figure i am running synthetic so I am getting close 300 miles over 's recommendation.

What was the longest any of you waited to change your oil?

 

6.5 to 7k once. i had the mobil one extended performance at the time. i wouldn't wait that long again. i usually do it at 3-5k with an occasional 6k thrown in there. i always use the extended performance so, technically, i'm changing it "early". it shouldn't be too bad unless you beat the **** out of your car or are like 10k over.

 

Depends on how hard you drive the car. I don't track my car or launch it really...so I tend to push out about 4k miles, then it gets changed, but only with Mobil 1 Fully Synthetic.

If you drive it hard/track it, make sure you change it every 3,000 miles. Also, make sure you only use fully synthetic oil (Owners manual calls for Mobil 1 Fully Synthetic).

 

you really don't need to change it before 5k miles. the 3k miles thing is a myth. My DD i have gone up to 8500 miles. No issues.

 

i waited 10k to change the oil in my MB ML500, 10k was the recommended service.

 

I changed it after 3k miles from when i bought the car. changed it with mobile 1 synthetic extended and still havent changed it and have put roughly 4.5k on it. will probably change it around 5-6k miles.

 

ive gone 15K on my mustang before withouth changing it but thats my beater. my dads gone 28K in his daily hyundai before, he just checks to make sure theres enough in it every month lol

 

As everyone has said, it depends on what type of driver you are. Do you drive hard? Then change it a little earlier. If you're using full synthetic then changing at 3,000 is a bit early, might as well use regular oil.

 

I change mine every 3500 miles at most. I try to stay around 3000 at most. When I had my 420A DSM turboed I went most 4500 miles.

 

I'll keep it around 3k. If i'd really have to push it, 5k at the most. Don't mind since i only pay 20 bucks for an oil change.

 

8-10k using AMSOIL or once per year, depending how much I drive the car, as its not my DD.

 

I change the oil every 2,700 - 2,800 miles/ 2 months if the car gets raced. if its regular/enthusiastic driving 3,000-3,300/3 months.

 

27k miles in the Evo. Here is how without damaging your motor:

I change mine every 3000 miles because I am **** about things like that however I am pretty confident the intervals could be stretched out much longer. Next time you change your oil, send it out to get analyzed and then you will really know the condition.

 

Every 5000 miles or every 4 months.
