Oil Change every 3K? What a joke.

Oil Change every 3K? What a joke.
Oil changes must be a cash cow for the dealers.
Why are people changing oils every 3K, just because the manual says so?
What a waste of money. The oil is barely used. There is probably more detrimental dirt being introduce into the engine by the kid that does the oil changes.
Just because the oil looks dark does not mean it is no good.
It is the viscosity and quantity of oil that keep the rubbing metals apart in the engine.
I have been changing oils at intervals of 15K, or once year on all my past 9 cars and have no issues what so ever. I personally change my oil with great care to not to introduce dirt into the engine and use full synthetic oil. I always make sure oil is top up to MAX. Heck one of my 90s Toyota manual have a more realistic oil change schedule of 12K for normal use and 9K for heavy duty use.
Are most people getting caught up on the oil change hype by advertisers?![13](https://g35driver.com/forums/images/smilies/13.gif)
You are probably doing more harm by the frequent oil changes with dirt introduced, and the few seconds of oil starvation from the re-priming of the oil system after an oil change.
Do yourself and your wallet a favor, extend you oil change intervals.

exactly, VQ are notorious for making oil disappear. I know my oil wouldn't last that long. Good luck getting any warrantee work done the second they find out you're going 15K between oil change. This is the same reason people follow the expiration date on milk carton, i'm sure the milk won't go bad on that exact date, but goodluck drinking spoiled milk.

Do you guys think for a second you are going to get a master mechanic to change the oil in your car?

I would not doubt that the oil consumption issues is related to guys not checking on the oil frequently. All it takes is to run low on oil and stave the engine once and you are going to have the oil consumption issue. Do you guys check the oil level after taking your car in for an oil change to make sure they don't under or over fill?

For OP
Even if you introduce dirt into the system by the fill hole there is something called an oil filter. If you change the oil at extended term. I would really like to see a tear down of your old motor VS a person who changes their oil every 3K...
So, you're telling me that you are okay with blow-by particles in your car for a long period of time instead of a new batch of oil with maybe a little bit of dirt through the fill hole? First, Oil has the characteristics when it is new to absorbs the dirt and then the filter will help remove most of it. So, unless you pour a pound of dirt into your fill hole then it won't matter. Another thing is our cars are high performance cars. They run hotter then a Toyota hence heat is #1 enemy of oil. It causes it to break down and lose its abilties.
People like you who changes oil at their own intervals are the ones that comes to the dealership for a trade in and if you look inside the fill hole the whole top valvetrain is probably black as hell from neglect. But whatever...I'll make sure not to buy a used car from you...

Sure starving of oil is definitely the best way to kill an engine.

I'll bet the noobs and the guys at the bottom get change the oils. Maybe the janitor if they are in a bind.
You will be lucky if they spend the time to use clean funnels and carefully wipe clean all the filling and drain openings of dirt. Heck, you might find the occasional gem of an oil changer that might be caring enough to pre-fill the filter with oil before installing it. ![Icon30](https://g35driver.com/forums/images/smilies/icon30.gif)

I change my oil every 3k miles because i run my car into the ground and beat it like a red headed step child. For the 40$ it cost to change the oil i would just rather do that then risk something breaking.
