I like to change oil myself (ensure plug is in correctly and filter tight). How difficult is this for my 2006 Porsche Caymen S or should I just take to dealer?

If you have changed brake fluid rather than topping it up the brake
system should probably be bled. You must ensure this is done so that when you put your foot on the brake pedal the car stops
You state that you changed oil, hopefully you changed the filter too? If you did ensure the filter is as tight as you can hand tighten it and that the sump drain plug is securely tightened.
You need to make sure that the coolant / anti freese is at the correct level and in the correct concetration.
You should check that your wipers clear the windscreen effectively leaving no smears.
You should make sure that your windscreen has no major damage
You have to ensure that all your lights work.

Make sure your tyres are legal.
You should probably have a service to check the engine/gearbox/steering/suspension/brakes etc

There are a few more but those are the basics

good luckn

check that the correct oil filter is used as some aftermarket filters lack an anti drain back valve and so the hydraulic tappets run dry for a small time until the oil pressure builds up. Check the oil level to ensure that the sump plug was fitted tightly or the filter is not leaking at the gasket. Check the viscosity of the oil used in the change.

Hello there
The location is the same you should have no problems.

Really easy but you need a couple of tools but they're cheap. The drain plug requires a 10mm hex allen head socket and the filter is the cartridge style that is easier to remove if you have a strap style filter wrench. Once you have these, all you need to do is remove the plug, have a big tray, 9 quarts in the engine. Then remove the housing that holds the filter, pull out the old filter, stick the new one in and replace the housing, hand tight. Everything is easily accessible underneath the engine, it may help to jack the back up a little.

you will need 5qts of 5w-30 oil and an oil filter. Go to an auto parts store and tell them the make model and year of your car and they will give you the right oil filter. Make sure to drain all the oil out then remove the oil filter. When putting the new oil filter in make sure to take some oil and put it on the sear of the oil filter. Screw the oil filter on hand tight and put the drain plug back in. Add oil to your motor, start with a little less then the owners manual says and start the car for a minute then turn off and check the oil level. Add and repeat till the oil level is correct.

If you did not do the oil change it is possible A) the plug was not tight, B) the filter was not tight, or C) the correct amount of oil was not installed.
Check oil level.

jack the car and support it on jackstands. put a can or oil catcher under the oil drain plug then loosen but do not remove the plug. slowly start to remove the plug letting oil drain out . when all the oil is drained remove the filter using a filter wrench available at most auto stores for under $10. hand tighten the new filter acoring to the instructions on the filter then replace the drain plug. Now add up to the specified litres of oil and check under the car/truck for leaks around the drainplug and filter. now you are done

Gravity does all the hard work. If you can figure out how to work a wrench, you can change your own oil. I'd pickup a repair manual, it will have the basics that tell you how to do a tune up/oil change etc.

You should also google Porsche groups, I'm sure there are a lot of greasemonkeys hanging out there who love to train noobies.

Its not difficult, but you need to make sure you have the right filter, and know where the drain plug is, before you get started.

Basically you drive the car a bit to get the oil warm, then you park it and set the brake. Put a drain pan under the oil pan near the drain plug. Unscrew the drain plug, wear rubber gloves, the oil will be hot, let the oil drain into the pan, now fish around in the pan for the drain plug that you dropped into the hot oil cause the oil was burning your fingers, when you find the drain plug, clean it off with a paper towel and open a beer. Now you need to remove the old oil filter, they usually either unscrew or are in a cannister, that service manual I told you to buy will tell you where it is and how to remove it. now open another beer, and put the clean filter in wherever the old filter came out of. Best to order a pizza now or you'll be drunk by the time you get this job done.

Okay clean filter is on, time to put the drain plug back in the oil pan, if its an aluminum pan, you probably should use a torque wrench to make sure you don't overtighten it and strip the threads, otherwise just put a new lock washer/crush washer on the plug (it should come with the filter)
Now add some quarts of your favorite oil after opening one more beer. That manual you bought will tell you exactly how many quarts of oil your engine will hold.

After its all together, check the dispstick to make sure you have enough oil in your car, then start the engine and move the car, look underneath for oil leaks, thats a sign that the drain plug isn't tight enough.

Take it for a test drive as soon as you sober up from all the beer. Easy peasy.

Remove allen key drain bung in centre of flat sump pan to drain oil, then using oil filter removal tool unscrew plastic oil filter housing situated just forward of sump, replace filter and sealing ring/washer. Refill via filler tube 8 litres and run engine till hot. leave for approx 2 mins and check level via instrument cluster (job done and saved £200)

Find a slot for that thing on your computer tower or desk top. Thanks!
