Did your oil analysis suggest any merit to changing oil at 5000 miles? Or even at 10000? I ran the 16,000 mile intervals on my prior LR Discovery and no issues to 100,000 miles at which point I sold it for the defender. I did an oil analysis one year which suggested the 16,000 mile oil still had plenty of life in it.

So I'm intrigued if there is any evidence behind such low mileage oil changes. I know back in the past that was an issue but modern engines and modern oil tech has moved on.

Dealers make good money on oil changes and annual services so I don't think they would push the intervals so long if it wasn't merited.

 

Sorry this is somewhat off topic: Is there a way to use an extractor for the LR3? My LR3's skid plates are banged up from off-roading and an absolute pain to take on and off. Feel free to PM me to not stray too far off topic.

 

ls the shorter oil change interval more necessary on a diesel engine?

 

I believe on the diesels, the oil is changed on every Fibonacci sequence mileage with a jar of glitter and gypsy tears added every other cycle.

 

The numbers do seem to support changing it every 10k for my use profile. Arduous condition criteria are largely met with towing, off-roading and plenty of cold/mud/slop etc.




Here is a link to my most recent analysis.

 

Sorry to say I don't think so. Pretty sure the extractor method began with the LR4. You need a direct path to get the extraction tube to the bottom of the oil pan.

I remember what a pain it was to do an LR3 oil change. I used to put it at offroad height then drive it up on RhinoRamps. I did figure out that those orange Home Depot buckets were the right height to support the skid plate while I wrestled with the rusted bolts. I even wire-wheeled the rust off the bolts and applied teflon lube before reinstalling them.

 

Ack oh well. Still have to drop the plate to get the oil filter anyways.

I usually put it in off road height and pull fuse 26 so theres no power going to the system.

 

On the LR3 it depends whether you can get the evacuation tube down to the very bottom of the oil sump. On more recent vehicles there is a small metal tube just inside the oil fill cap that goes to the bottom and you just connect to that tube and vacuum it out. On the LR3 could you guide a narrow pipe down to the bottom of the engine to extract? Eg down the dipstick hole for example?

(As an example on my jetski I change the oil with an extractor. I just undo a rubber oil pipe at top of engine which goes straight down to the sump area and feed an extractor tube down the pipe)
