Not bad, just not necessary. There's no such thing as changing your oil too much but to do so is a waste of time and money.
New and Happy Mazda3S Owner!
- Thread starter PWR SHFT
- Start date
there is a thread crossbow posted somewhere that showed the oil is just breaking in at 3k. Any full synthetic changed at 3k is a waste unless you been running the dog crap out of the car. I mean coast at 4k for like blocks at a time.

well but i have it free from the dealer
YOU CANT CHANGE YOUR OIL TOO OFTEN OR TOO SOON. PERIOD!!!
Just because Mazda says that its OK to change your oil every 5K (or 7k miles(shocked) ) miles, doesnt mean that you have to wait that long.
Now for the oil lesson. (rant)
There are two things with oil that you want to protect against.
Oil breakdown and Oil contaminates.
Oil breakdown occurs usually due to three things: hard driving, excessive heat, or excessive mileage. This is where the manufacturers recommendation comes from. Most of us will never dirve there cars hard enough and generate enought heat to break down oil. Mileage is the culperate. With todays oil, 7k miles is usually OK for this.
Now something that the manufacturers don't look at closly enough for me is contamination. How does oil get contaminated? Well there are two things that are the biggest contributers. Condensation and blow-by. Condensation - this happens as your car cools or sits for periods of time. Your crankcase is not completley sealed. Moisture will get inside and condensate. This effectivley causes water in the oil which will cause it to seperate and also cause corosion inside. Today's oil has additives to help with this, but I wouldn't trust it. Dealing with cars that sit around a lot, this is more of a concern. But for people who drive there cars everyday, not so much. Blow-by - your piston rings DO NOT completely seal the air fuel mixture inside the combustion chamber. Some WILL get past the rings and into the oil. When this happens, gasoline gets into the oil. Now you may trust that not much will be getting into your oil over 7K miles, but I won't. Gasoline and oil do not mix! The longer you drive, the more gets in there.
That is why I change my oil every 3-4k miles. CONTAMINIATION.
Thats all I have to say (blah)

All I have to say to that is:

If you're that worried about contamination, then have your used oil analyzed and they will tell you exactly how often you should be waiting to change your oil. Not general data but receommendations specifically for your car.

The first link is very interesting. Good to know we have a good engine.
However, I will not go through the trouble to have my oil analyzed for a Daily Driver. If I just change my oil ever 3 to 4k miles, I won't have anything to worry about. According to www.bobistheoilguy.com, the only thing negative against changing your oil more often was expense and oil disposal. That's it! If anyone is that worried about saving the extra periodic $30 dollars to change your oil a little more often, you shouldn't own a car.

Of course you can do whatever you like but if it's not necessary, it's just wasted effort (in addition to the wasted money).
Personally, I have enough other things to worry about in my life. I don't need to add over-changing my oil to the list. I like changing at 5,000 because it keeps things nice and even and I can rotate my tires at the same time, so there's less things to keep track of.
