No matter what i try 3000 rule always. I like to change my oil.Originally Posted by mespork
I have a new 06 mazda3. The manual says to change the oil every 5000 miles in my climate / driving conditions. This is the first car I have ever had that said to change the oil every 5000. I did the first change very early (out of habbit), my question is should I let it go anotherr 5000 miles or stick to the old 3000 rule??
This post college life is a real drag
5000 is fine. The 3000 rule was made by oil companies who benefit by you changing your oil more often. When I was younger I worked at an oil change company and truth be told, most cars say 5000, some even more. The 3 month thing is the same way. Its not gonna go bad just sitting there.
i change the oil myself, on a 5000 mile basis. I use fully synthetic oil though, 0-40 Mobil 1, the best oil for my car. It's actually funny, that back in europe you had to change the oil every 10-15000 KM ~8-9K miles apart. So basicly they are pulling everyones leg, by having this 3K mile rule. I don't do it only b/c it'd get mad expensive. I do my own oil change, and this way it cost's me ~$40. $5.50 per quart. plus a Mobil 1 filter for like $13. So it's pricey, but way worth it.
I recommend you to use synthetic oil. It's better for your engine. Keep it maintained nicely, and you casn go 3-4, magybe 500 000 miles easy
Personally I change my oil every 2500 miles. It maybe true that you can go 5000 mile or more but my theory is why risk it. Itís insurance. I want to get what ever trash there may be floating around in my engine out of there, be it metal, water or all the byproducts from blow by of the piston rings. I also change the filter every time, same reasons. From what I have see in car manuals, the 5000 mile thing usually say something like under normal driving conditions, but under harsh driving condition change every 3000 miles. There definition of harsh driving conditions is most peopleís normal driving conditions, like stop and go, driving up and down some hill, driving for short distances, and stuff like that. Hope that helped some.

every 2500 is overkill, unless your car sits for days at a time between drives. otherwise, 3-5k is not going to harm your motor at all, unless you beat the **** out of your car on a regular basis, or if you have a turbo which is oil cooled. Then, 2500 is ideal, and use synthetic. Mobil 1 is good choice, and has come down a lot in price. That stuff used to be over 5.00 a qt.
I do every it 5000 miles. Or when my engien eats the oil and I need to put more in
and your car also gets 11 mpg.Originally Posted by rev2

Fun > MPG any day of the week
I do keep track of miles - but also look at the oil,
if the oil looks burnt or real dark or smells bad - I
change it out, if the oil looks good, I leave it alone
the same for transmission oil, underware
