My current 2000 S80 T6 seems like it's having a bit of a sludge problem. When I started the car this morning it took a few seconds for the oil pressure light to go out with the message low oil pressure on the message center. ( Went out after a few seconds) . This also happened over the weekend.
My question is what product should I use for a engine oil flush. The car only has 127,000 miles on it, so I think it has a lot of life in it. Thank you again for your help. P.s. this isn't the car I plan on buying in March which needs a oil pump.

 

I would not do an engine flush. Start with removing the oil pan and cleaning out whatever is there. Also, replace the O rings that are part of the oil pan.

Do not mess around with this. Get it fixed.

 

Okay, I'll have to see how much the garage next door will want. I would do it myself but it's been way too cold outside to do anything. I did forget to mention that both times that this happened the engine was cold. So I'm not sure if that has anything to do with it. It was in the 20s both times.
Thank you again for your help.

 

Are you using FRAM filter?
Are you using synthetic oil?

 

I know better then to use fram oil filters. I've been using purlator filters and will be using Bosh for the next change, it uses the cartridges type.
I use a synthetic blend. 5w 30 in the winter.

 

the caution about after market filters is that they may not have the flow rate that OEM filters do leading to starvation at low engine speeds. OEM Mann filters are cheap enough...

 

I misspelled Bosch , but what brand should I use?
Here's the part number for the filter I bought....
72206ws . I thought Bosch was a good brand.
Thank you again for your help.

 

that part will fit your car - the comments about choosing filters were "best practices" and not specific to your issue at hand. Tony1963 had it right - if you are getting oil starvation, you likely have debris in the oil pick up or a worn oil pump. not properly investigating the root cause of a low pressure light will greatly shorten the life of your engine. Note that I had a similar problem in my 2012 VW CC with 49,000 miles on it. The shop dropped the pan only to find debris in the pil pick up. Given the car was still under warranty, VW approved the dealer to drop in a new long block ($9500 repair)...

 

Okay I will definitely look into removing the oil pan soon as the weather warms up. Like I said before when this happened it was the first cold start for the day and it was very cold outside and it was out with in 5 seconds . Any other time when the engine is warm or when it's warm out the light goes out in less than a second. I figure that it's close enough to needing a oil and filter change , about 600 miles left(every 3,000 miles for mine) . I'll be doing that this weekend hopefully. I'll take pictures of the filter if something catches my eye.
Thank you again for your help.
