I just moved to Austin TX and was hoping I would finally have a good experience at a Jag dealer. I made an appointment to get an oil change at Sewell Jaguar and when I arrived the service advisor quoted me $425 dollars for an oil change saying that was the standard price but might be a bit cheaper because my car is older. Every other dealership I've taken my car to for an oil change charges around $250. If Sewell is charging $425 for an oil change I don't want to even know what they would charge if something major went wrong. Does anyone know of a good independent Jag shop in the Austin area?

 

Buy a $10 extraction pump and seven quarts of oil. Suck the old oil out through the extraction tube inside the valve cover cap. Pour in new oil. It takes about ten minutes total, and you do NOT have to go underneath the car.
The filter is on top near the front. Take off the cover, replace the $12 filter and reinstall the cap. Total INCLUDING the pump which you will use every time, about $70.

 

Best advice I’ve heard this month.

 

Not for YOU though, the 4.2 liter models don't have the extraction tube.

 

On the 4.2 you can slurp out around 5 liters through the dipstick tube. I do it every other oil change (six month drain and new filer) then just slurp the next one - my mileage is low between changes.

 

Are you using the dipstick tube itself as the extraction tube or inserting a plastic tube down inside the dipstick tube? The former technique works well on engines which are designed for that approach whereas the latter usually works well on other designs but you usually need a fair amount of tube adjustment during the process to extract all the old oil.

Thin plastic tube down the dipstick tube. Ya, you have to fiddle the tube around to get as much out as possible. Use the same technique on my sailboat inboard.

 

On my sailboat Yanmar inboards, I push a 6mm diameter tube right over the outside of the dipstick tubes as the engines have a metal dipstick tube which goes right down to the bottom of the sump and is designed to be used as the oil suction tube. It also has the advantage that the dipstick tube is much bigger diameter than a plastic tube which would fit down inside it so the oil flow is much higher and the sump empties completely in a minute.

I have the 1 GM motor - not sure if the dipstick tube goes all the way down. I'll try your method as I'm due for an oil change.

 

Please reply in this thread and create a new thread specifically for 4.2L models. Let us know if you can suck out the oil with the vaccum hose tightly fitted over the dipstick tube. Thanks.

 

There is a trick with my YMs in that they have a small vent hole a cm or two down from the top of the dipstick tube so you have to push the larger diameter plastic tube down enough to just cover the small hole otherwise the suction won't work. My engines were specifically designed for marine installations where the sump plug would be unreachable so your GM might well be the same.

On the 4.2 why can you not just change it the tradional way? Just had it done at the local mechanic and with a few other things and he didn't mention any difference?

 

I prefer to drain, even on the new motors. With the filter on the bottom on the 4.2, you’re already there. I reckon you could do both and not have as much oil to drain and perhaps a bit less messy. With regular intervals and full synthetic oils, the only benefit to oil changes is removing contaminants, and gravity’s the most thorough, IMO.

 

Mine's also a 4.2 and I drain it in the conventional way as you have to get underneath to get to the oil filter. My VW has the oil filter at the top of the engine so using suction to remove the oil makes sense.

I lived in Austin for a year and had the displeasure of visiting that dealership a few times. They are undoubtedly the worst dealership I've ever dealt with across any brand. They're condescending, rude, and suck at their jobs.

They damaged my F-Type on multiple occasions, admitted to it, and replaced parts they damaged after me catching them in their lie.

They suck.

 

We have 4 JLR produces and 3 with the 5.0 motor. I loathe doing a traditional oil change after getting an oil extractor.

 

Is there another shop you recommend?

 

There's absolutely nothing special about the 4.2 oil change and no reason for $425. It's drain new filter and refill like any other car

Extraction makes more sense on the 5.0 because the filter is also right on top

 

But the OP has a 5 litre which at the main dealer uses JLR overpriced proprietary oil.

A proper Mityvac extractor’s about $120, the correct oil from Pennzoil Ultra Platinum’s $60 for 9.5 litres and a genuine filter’s $30 (tried multiple aftermarket filters and none fit correctly or leaked). Just did my oil again last night as I have for years. Takes about 15 minutes with setup and cleanup and saves a trip
to the main dealer.

 

Bought my 1st Jag in January 2023 1999 XK8 convertible took it to a private foreign car shop in Florida full synthetic good filter, inspection $100. Come to the sunshine State.
