Title: Oil & Sensor Trigger
Post by: AGB on 24 August 2010, 06:59
Hey Guys

Wondering if I could pick the group's collective brain.

1. My car has just cleared 3000 miles so I decided to carry out a full check of consumables and on checking oil levels, noticed that I was quite low, slightly below the minimum mark. I would have expected an alert on the dashboard warning me when I hit the minimum level at least. Has anyone else experienced this? I just wonder if the oil sensor is not working properly or whether the warning alert is a seized engine? Wondering if I need to go into VW and have them recalibrate the sensor, it's not something that I want to take a chance on.

2. When I bought the car, I bought some oil as recommended by the dealer. Mobil Syst S 5W-30 Special V Synthetic. It's rated as VW505 01. Now looking at my owner's manual, my engine oil spec is with LongLife Service which is VW 504 00. Looking at the product spec on the back of the bottle, it appears more suited to high performance diesels and the fact that it doesn't match the spec rating as per the owner's manual means I don't want to pour it in and hope for the best. Can I use 505-01?

Thanks



Alex

Hi Alex:
504 00 is the specification for the latest VAG engines which are Euro IV complaint and which require lubricants of low sulphur, low phosphorus and low sulphated ashes rates.
The back compatibility is for 505 00, 505 01 and 502 00. So you should be ok.

I use Motul Specific 504 00 which our resident oil expert mac7, I think, also uses and recommends. You can buy it from:

I may be wrong, in which case one of our friends will correct me; but I don't think the oil sensor works on level, it probably works on pressure, so if your oil pressure is at least at minimum required the alert will not flag up. But best advice is always check your oil level regularly, don't wait for the alert, particularly until you've done 2 or 3k miles. After this the oil consumption should reduce.

Cool. Thanks, that makes sense.

I do check my oil more regularly than 3000 miles! I just have a habit of doing full checks at milestone mileage then I have a point of reference that I can remember.

Should be two sensors - one for pressure and one for oil level

The oil level is right at the base of the sump and I've always thought if the light came on for that then you can kiss goodbye to your engine as there's very little left in there!

Didn't you ask for some oil Alex? VW used to give you a litre of oil with every new Mk5 car sold. Obviously they are saving money. I asked about this and they gave me a litre which would have cost £15.

No as previously mensioned the oil sensor only measures pressure and there maybe another one that measures temperature.  ;)

I didn't mean you only need to check the oil every 3000 miles, I check mine every couple of weeks; what I meant was after 2 or 3K miles the oil consumption rate will reduce

Yes, the oil temperature is displayed on the MFD if you scroll through.

Isn't it weird? One member's worrying about his oil level after 3000 miles. I never came close to having to top mine up in the year up to its first service in July. 12000 miles it had done by that point.
How come there's such a difference?

Well every engine is different. I was told to check the oil level regularly as they do use oil while beding in. The first 1500 miles it used 250ml for the last 1500 it hasn't used any. I'm also told mine doesn't loosen up until 10,000 miles.  :wink:

Cough 7,500 miles, it has used about 2mm on the dipstick, so not topped it up at all yet.

Diesel probably different in respect of oil use. I was told to check mine regularly for the first 2K miles or so, needed ½ litre after 1000 miles and another ½ litre up to about 1500 miles. Not needed to top up again recently.

I for one can't get my head round the Oil situation on my car.

Mine is a Mk5 Golf GTI 57 plate with 58k when I bought it. I bought it from a lease company so took it for a service straight away. The VW garage filled up the oil on the max line.. Anyways 1,200 miles later it was on the minimum line on the dipstick!! I took it to the garage and they couldn't fine any leaks so they topped it up. 1,200 miles later its done it again. This time I topped it up to the maximum line and checked the oil. 1st week I covered just over 100 miles and there was no oil loss. Then the 2nd week I only did about 80 miles which took it to over 200 miles and it went from maximum oil level to nearly half way!!

I then decided to take it back to garage with my findings and left it with them for a couple hrs. They could not find any leaks what so ever and no oil residue on the exhaust or anything. They topped up the oil again and asked me to use it and to bring it back as soon as the oil level drops! but strangely enough it hasn't lost any yet. I'm on nearly 800 miles and its still on the maximum line..

Can anyone explain this? i'm approaching the end of my warranty so i'm hoping it does it again so whatever is causing the problem can be fixed.

Thats not a service topping the oil up and how much did they charge you for that minor detail?  :wink:

They did a filter service as well etc. I took it for the service the day I picked it up. Sorry that wasn't clear in my post..
