Thank you for the advice. Unfortunately, neither my engine has that small tube, nor a dipstick. It's a 30d and here is a photo of the engine bay. In my opinion, what I circled out in red, seems to be the only possible place to suck oil from. However, it's a twisted hose, it's not a straight pipe... is this the right place to take it out from?Depending on which engine, under the oil filler cap is a small pipe, attach your suction pump to that. If no pipe then via the the oil level dipstick tube, insert a smaller diameter stiff tube into it, connected to your oil suction pump. Such tubes are usually supplied with the suction pump. Caution though, don't drop and lose that tube down the dipstick tube! Warm the engine first, idle for 5 to 8 minutes is enough.
I know, that's why I want to remove the oil so it's not at the maximum. Jaguar dealership did the oil change, I checked the oil level the next day and it was full to the max and probably above... who knows how much.When I had a 3.0D, I kept the oil 2 notches down from full, measured when warm. That way I could keep an eye if oil dilution was occurring as the level would be seen to increase. Not that mine ever did. If you fill until it's completely full, you'll simply get "Oil overfull" should dilution have occured and you'll not know to what extent.
No, I check the oil every 1-3 weeks, I've never seen an overfill warning. Back then I didn't know about the oil dilution problems and after they told me the oil was 1l more, I realized I had to be more careful to avoid headaches. That's why I wanted to be on the safe side and remove some of the oil.You won't get an overfull warning, it'll only advise this when the level is checked, the display will say overfull. You will get a warning for low oil level though.
I haven't changed oil myself yet. Does the extraction pump take out everything? Or you need to drain from below as well?I change my 3 ltr Diesel oil by using the extraction tube (8mm tube fits over it I think), I put in 6 ltrs then check the oil level & usually end up putting 6.5 ltrs in & that is 2 notches down from max on the electronic dip stick. So that would equate to each notch being 0.25ltr as mention above. The oil filter is mounted on top of the engine under the engine cover too so the whole process is simples!
I started doing my own servicing out of warranty. My extraction pump has a litres measurement so I am sure it takes almost all of the old oil out; btw Jaguar use this method in the dealerships.I haven't changed oil myself yet. Does the extraction pump take out everything? Or you need to drain from below as well?
Also, is it easy to change the fuel filter?
