Thread: Oil Change every 5000???

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

There definition of harsh driving conditions is most people’s 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.

in reality, there is no such thing as normal driving conditions. But, also consider the type and weight your owner's manual specifies, and don't use something different. If your new Mazda says 5k is ok then do it. Just don,t get cheap and use no name oil and filters. there is a difference.
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

Yup

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
