hey all, sorry for the newb question again but wondering about oil changes. i wanted to change the oil in my 'new' baby but didnt have easy access to ramps so decided i would run it by jiffy lube for a quicky. no go. both jiffy lube and another quick change joint said that they will not change oil on porsche's as 'policy'. i had never heard of that before. why would that be?
so of course i figured i would just eventually try to change it myself and then found that i couldnt find filters at the normal autoparts stores. hmph. getting a bit more difficult.
what should the new owners know about changing oil ourselves? i had already decided on using the mobil 1 15-50 , now i just need to figure out how to get filters. can these be purchased locally or does one have to go to the dealership to get the oil changed?!

Well you can usually buy a set of oil filters for a 928 on Ebay, but one of the big 2,3,or 4 can usually supply these as well, get the correct filter. You will need about 8 to 9 qts to fill the engine with a new filter.
Put 8 in first then start the engine let er run for a while then check it
As far as jiffy lube not wanting to work on your car I would bet that a noob oil changer has had a hand in frying a PORSCHE motor so they just dont want to repair/replace anymore p car motors

It's very straightforward. You have to remove the undertrays first of course, and as well as a new filter get a new washer for the sump plug. Get the motor warm before you remove the sump plug.

Removing the undertray is what stops Jiffy Lube. Heck, I hate doing that too. Otherwise, it's nothing unusual.

When you order an oil filter (or three), make sure you also spring for a brand new sump plug sealing ring 900.123.118.30, be careful though, it could cost as much as 60 cents....

When you install the new oil filter, fill it within an inch of the top with clean oil first, to minimize the time it takes to regain oil pressure when you re-start the car. On an S4, the tighentening torque for the drain plug is high- 37 ft lb. Dunno about older cars.

thanks for the quick replies!
do you all have a place you recommend ordering filters from? ( and i guess the washer too (same as sump plug sealing ring?)..)
amazon.com is usually good for me in terms of delivery and getting stuff quickly. will take a look and see if they carry them.
good ideas on filling the filter with oil before putting it on the car.
as an aside, it is amazing how much oil this thing holds. i had an '89 mustang gt 5.0 and if i remember right that used about 6 quarts which seemed like a lot....but its worth it. this engine pulls so much sweeter than the mustang.

Be thankful you didn't have a quick change do your oil change. WHen I bought my car two years ago the PO had just taken it to an oil change place in anticipation of the sale (to be a nice guy).

Stoopid grease money put the drain plug on with an impact wrench. I had to cut the plug off. At least they didn't strip the threads of the oil pan.

Another tip... make sure your oil catch can hold at least 12 quarts. Some of the smaller ones don't give you much room to tilt and pour the oil into your recycle containers and you end up spilling old oil all over the place. Ask me how I learned that one a long tme ago?

I use one of those oil change pumps that has a plastic tube you slide down the dipstick tube, do not have undo the drain plug, crawl around underneath (except to change the filter), spill old oil everwhere &&&&&

You've never known real excitement until you find your 8 quart catch can full and MORE coming!!!

On a related side note, do all of you subscribe to only needing to change your oil once a year?

AO

Yes... I mean No... it depends really, sorta, kinda... ummmm what was the question again?


It all depends on how many mile you drive your car and under what conditions. Some say one a year is sufficient, but then the question so when do you change it? Before winter, in the Spring? It's enough to make you go crazy.

I would say no less than once a year. If you're really ananl about it, do it more.

Bill Ball

I think this is perfectly OK. I change my oil acccording to Porsche's recommended schedule once a year or 15,000 miles, as did the PO. So far, (187K miles), it seems to be OK. I still have perfect compression numbers and the car runs as it did when I got it 115K miles ago.

There might be some driving conditions that would shorten the interval, such as a lot of very short driving trips that don't allow to reach full operating temperature. Open road racing that I do does not change the schedule, as I am just driving the car as it was intended to be driven.

macfly4

once a year?! i always followed the 3-4000 miles on my mustang gt. guess it was overkill. i expected to do about the same for this car. then again, not sure how many miles i will be putting on. just hit 50k and would love to keep it low.
thanks for the info. .....hey rob, just checked on 928 international. those sump washers are now $1.00 a piece....wow. thats an expensive washer. not a big deal but sheesh, they sure seem to nickel and dime you.
by the way, since im at it, what do you suggest as far as air filters? is that also a once a year, same time as oil change thing? and do you recommend the original filter or the K&N twice-as-expensive one?

They are made of copper. War materiel and all, don't ya know.
