Can I change oil filter without flush oil?

[bing1221]

Just want to change the filter only, is that safe without flush all oil?

[bing1221]

no one?

[rotate]

Yes it's safe, but why?

[nc73]

Yeah usually people change just the oil and not the filter...

every day, I start my car, I got this msg "oil pressure low.........." on the SID with in half second, then gone. I sent to dealer, they replaced sensor and switch, but still happen.......So I want to try to change the oil filter, see if happens again........Dont want to drive 30km to dealer again.

I see that you have an MY03 model. That problem is normal on that YOM, what you need to do is have the dealer update the ECU software. It is actually a glitch in the software logic, it checks the oil pressure too soon during starting and before the oil pressure builds up which is dumb. I had the same problem until the dealer updated the software during one of the scheduled service and it went away. Never came back.

I don't think that applies to anyone in this forum...

Exact.. I am sure that 99% of us change both at the same time and probably more often than necessary; but that does no harm. No, I am not trying to open a debate that has been thrashed and rethrashed...

I'm gonna be bold and take a chance, I think everyone here is gonna change there Filter when they change the Oil, wether it be @ 7.5K or 15K or anywhere in between. it's just silly not to, there is dirty oil in the filter.

Due to possible sludging issues, i'll do 3k. So it would make sense for me.

You have an 00, there are known sludge issues with xxx, your forgetting your talking in an SS forum.

correction: meant to say 93 rather than NG as opposed to 93SS

yeah I realize that but always better to be safe than sorry.

The B207 engines (or GM-Opel Z20NET, and their non-turbo counterparts Z22SE) do not have any record of oil sludge problems.

Anyway, i'm due for an oil change soon - the filters (will change the air too) are waiting in the garage and this time i'm going to do it myself (first time on the saab, but i have always done it on all of my cars). I am doing it every 10kkm, that would be, approx. 6200 miles...but i guess i could safely do 15kkm, but...with my redlining driving style it will never hurt.

I didn't know ther was an update for this. My MY2003 also did this quite a bit so I assume it's normal. Don't worry about it.

you might want to check in the NG900/93 forums before you make a blanket statement like that, heres a few pages worth:

GM's Saab recalls 400,000 cars over engine flaw STOCKHOLM (AFX) - General Motor Corp's Swedish subsidiary Saab Automobile AB said it is recalling up to 400,000 of its 9-5 and 9-3 cars worldwide due to an engine design flaw.

The company said the flaw could lead to a rapid deterioration of oil quality and damage turbo-charged engines.

'As many as 400,000 cars may be affected worldwide,' Saab (Stockholm: SAABb.ST - news) spokesman Oerjan Aaslund said, refusing to reveal how much money the company would be forced to spend on the repairs.

The company said it will issue an 8-year retroactive engine guarantee for its 1998 to 2000 9-5 models and its 2000 to 2003 9-3 models. (However the design wasnt changed until 2004 so cars up to 2004 will be vulnerable)

'The guarantee means that customers who have been affected by motor problems due to oil sludge will receive full financial compensation,' Saab said in a statement, pointing out that the purchaser of a vehicle in 1998 would still have a valid guarantee through 2006.

The car manufacturer said that about 4 pct of the 95,000 cars equipped with the engines in question circulating in Sweden appeared to have experienced problems.

'Sweden has been more affected than many other markets... mainly due to the fact that it is colder here and it takes longer for the engines to warm up,' Aaslund said.

Plus all 9-5 and 9-3's with poor or no routine maintenance or where oil specification has not been adhered to.

JonV, i am perfectly aware of the sludge problem on the H-engines, but, again, as B207 has nothing to do with B205/B235, there is no documented cases of vulnerability to oil sludging of these engines out there and we should be all happy about that.

The date of 2004 relates to design changes of engines installed in yet produced 9-5 models.

This is the 9-3SS forum so let's keep the facts related to the car - none of the affected engines got it to any of the Epsilon-based cars (including 9-3SS, Opel/Vauxhall Vectra and Cadillac BLS).

nc73, who brought up the sludge issue, is an 00 Viggen, I was responding to his Sludge issue comment, reminding him that that problem was not an issue with our engines. That seemed pretty clear to me.

And I am well aware this is a 93SS forum, I've been in SC almost 4 years not 4 mos.
