Impossible to read when the oil’s new and not much better when it’s dirty. I think it gets smeared when you pull it out too, I don’t have a solution I’m afraid. I think the move to ever thinner synthetic engine oils is the cause, it just doesn’t stick to the dipstick like it used to.

I’m glad it’s not just me, did our 2.2 the other day an thought there’s got to be an easier way to get it right.
I keep reading 7 litres everywhere but ours I’d definitely 6 litres ( inc filter change) |

I have the exact same problem.. hard to read the dip stick. I sometimes feel that the checker design in the dip stick makes it worse. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

I usually lay the end of the dipstick on some paper towel. It's then easy to see where the oil is as it soaks into the paper. Darren

That's confusing, too. Driver's manual says 7.0 l, workshop manual 6.85 l, JLR dealer charged 7 litres (photo above is after a dealer's service). So I changed the oil the other day and after 6.5 litres I tought the stick shows "close to low", so I poured another 0.2 in but nothing changed or rather I couldn't make out any change 
THEN I read in various discussions the 2.2 would only need 5.9, 6.0, or 6.3 litres. And now I can't see, if I've overfilled it already :-/ What makes you sure 6.0 is right? |

I’m not 100% but 1st time I did it I went with the book & couldn’t be sure ( dipstick problem) It was way overfilled so drained it out & measured it.
Have done 45k since we’ve had it & changed it every 5k or so & 6L is pretty much on the top mark ( after about 200 mls it’s easy to see) hope that helps…. |

Thanks Timcat. Practical experience does help indeed.
I'll take it for a longer test drive and see if I can make out the level then. New oil seems to get dark pretty quick. |

Further investigations on the myths of the dipstick
This is what it looks like after a 6.7 litre oil change, when cold: and 2 hours after a 30 mile's drive: yeah, well... <facepalm> Friend of mine had the idea to not dip it in fully and see what it looks like then. First, control measurement: what's it look like when emtpy? how much oil is scraped from the tube? This demonstrates the problem: there should be no oil on the stick at all. But the bottom end seems to collect enough to partially fill the waffle pattern. Also the solid top end is covered in oil, which makes it impossible to tell if the level is above max. For comparison we wiped the top half with a paper towel: Next we put the stick about half way in: Green arrows roughly show where we saw two boundaries which could both be interpreted as the oil level. This range of error alone corresponds to about 500ml... (assuming it's indeed 2.0 litres from min to max, which is about 30mm) We didn't have time to measure how deep the stick was in, so I'll repeat this with more accurate measurements later. I've also ordered another dipstick, where I'll file off the useless pattern. Couldn't get much worse  |

Thank you for sharing.
Old engines that had dip sticks that worked were just a flat piece of metal. If after filing the checker pattern (which I would also recommend to polish to reduce capillary action), I would then suggest to file flat the bottom and top rounder portions just above and below the checker patters such that you have a full flat on one side. Make two small indentations on the side to mark the lower and upper limits for reference. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing 2012 90 CSW, 2.2TDCI, Santorini Black |

sooo, I did some more measurements
First finding: I get better readings when the dipstick is inserted with the waffle pattern towards the engine! With my dipstick that's if the imprinted part number on the handle's ring is on the side of the engine. You can see it in my previous pictures, which is the "wrong" way. I guess it's scraping less oil from the tube, that way round. When you remove the stick, at some point it tries to twist itself around, so keep a firm grip. The waffle is 28mm long. So I marked the yellow handle at 20, 25, 30, and 35mm. Click image to enlarge Then I inserted it only upto each marking, Click image to enlarge pulled it out and got these results 35mm - dry, BUT the top end of the pattern was a little oily; this may result in faulty measuments if the oil level is near the top and the stick fully inserted 30mm - wet at the bottom but barly noticeable 25mm - oil just on the end of the pattern 20mm - oil in the waffle for about 7-8mm, now we're getting somewhere; so had I inserted the stick fully, the level would be 20mm higher, which is on or just slightly above max
Click image to enlarge I repeated some of the measurements and think it's just a little overfilled, if any. 1mm - 3mm would correnspond to 70..210ml of oil plus another 70ml margin of error. That shouldn't be a problem, what do you think? |

Great insight macfrank
One thing to remember with the UK and EU 2.2 defender is they are equipped with a DPF. During a DPF regeneration sone diesel ends up in the engine oil, dilutes it and raises the level. This is one of the things the ECU calculates and contributes to the oil service light coming up. So good to do this check that macfrank has done some great work on when doing an oil change but realise that after a few thousand miles and a few DPF regens the level on the dipstick will show higher. Ps I always get 6.9- 7 litres in , maybe as I have the front wheels on ramps so all the oil is flowing out of the sump and I leave an hour or so . I fill with 6.5 litres, run engine, reverse off ramps leave for 30 minuets then fill to top of dipstick and it’s either 6.9 - 7 litres with my measuring jug. |

Thanks Ian. Also for reminding us of that oil dilution; I'll keep an eye on the oil level and will probably do the next oil change ahead of time.
Is yours a 2.4 or 2.2? |
