Personally, I change my oil every 4,000 miles....I noticed if you look under your hood it says "Normal conditions: change oil every 7,000 miles harsh conditions: 4,000 miles

How long do change your oil?

I use Mobil 1, a Pure 1 filter, and change every 3k miles. The oil still looks clean when I change it. The engine runs like a champ-smooth and silky.

I use Mobil 1 and change it 3-4K miles or every six months (I hardly drive it), which ever comes first.

I guess that I am a crazy nut, I change mine between 2000-2500 miles. I run my car hard.

I change every 4-5k and use Castrol Syntec. I don't trust a synthetic that doesn't smell like plastic.

I think Peter Scott did a dyno and some research to see if synthetic would be a better choice for our cars...From his results, Mobil 1 was as good as any other oil out there that was non-synthetic (ex: regular Mobil oil)...He claims that as long as you are changing your oil on a regular basis (3,000 miles)..Your motor should be fine...

Now if I can find the thread on this ..eek1:

3000-3500 here. I like to have my oil come out still clean! I use Castrol.

I change my oil every 5K miles and I think it's very reasonable.
Newer cars today like the Cadilac or bmw do not need to change oil until the light indicator goes on, and that could be 10K.

If the oil comes out black, change it sooner. Dirt in the oil is a bad thing, and I got filthy black oil at a 4000 mile change.

The dealerships send me notices every 5000 miles, so I change my oil between 4000-5000. I used to do 3000, but my oil was still pretty clean and I felt like it was a waste.

I change my oil every 4,00 miles using Castol Syntec ( I boycott Mobil/Exxon). I use 10w30 in the summer and 5w30 in the winter. The oil comes out not black, but much darker than when it went it.
