I only got 65ml out of mine, done 25k miles, tipped upsidedown and everything could not get anymore out.
I put back in about 80ml, powerhouse sent 115ml but was worried about overfilling.

Yip, I got 80ml out, 80ml in. Apparently you need to take off the black pressed steel cover to get all the old oil out. I tried turning upside down etc.
I had plenty of correspondence last year with Powerhouse-uk regarding the V6 supercharger oil change. They have since reduced the oil fill amount in their kits from 150ml to 115ml.
What prompted me to contact them was the ‘
Supercharged oil change on the V6’ topic....https://www.ftypeforums.co.uk/viewtopic.php?p=59480#p59480
This is some of the email correspondence I received directly from Powerhouse-uk....
“Hi, we have had a lot of enquiries about this recently so we've been looking in to it. We acquired data on oil levels from another source a few years back where it was stated as 150ml. With all the questions the past few days we have taken a few stock units including a new one on the shelf and measured across all we've got. We've also made a dipstick and double checked from a fresh empty blower just this afternoon and we have concluded that the true oil level is closer to 115ml. This would correlate with the 80ml removed as you can never remove every drop. We will be updating our database and ad's soon. As our other queries appear to have come from a forum post I'd presume you have also seen this? If so you are welcome to update the posts for yours and the jag community.”
“Also for reference, this came up with another query. If removing 80ml you wouldn't put 115ml back in. You replace what is removed, contrary to other comments this oil does not evaporate at a noticeable rate, it would take many years to notice any difference so 80ml removed is likely due to positioning of suction, casting features and some left in bearings and faces etc that take up the rest.”
“The fill level will now be 115ml as that is what we calculated. For reference the oil is supposed to be mid-point of the lowest ball in the bearing race. On other models you will notice that the filler bung is within mm of that position. This is what we calculated and dry filled 115ml to get to. All the oil kits have now been updated.”
“In reality there is no definitive interval, OEM say lifetime oil but we all know that is wrong. When things start to go wrong the oil tells you....early intervals will not perform better but serve to ensure gears and bearings are good. Only once the mileage gets up, in our case we see bearing wear from around 80-85k hence the advice. If a car has done 85k, after that point you are on aged bearings, possibly already had an oil change and the likelihood of bearing/gear wear is higher so from that point you start reducing the intervals.”
“This is all averages though, if you start looking at specifics you can get some superchargers at 150k with perfect oil. Others for example like the JR M62's with high failure rates we'd probably advise every 10k to try and catch any issues starting. On the F-Type 5ltr to be specific, if there is no other issue with the supercharger we don't see problems with the oil. Once the coupler starts to fail, if that has been left for a while it has been known to write off the supercharger wearing the rear gear set but ordinarily this doesn't happen. Couplers fail from 17k (lowest I've seen) 30-40k quite common, it would be best to check that regularly. Check oil only if you don't know the history, have some coupler issue or if it gives confidence everything is new.”
“With regards to service intervals, I'm sure that will be a long argument despite our advice so I'd say do whatever feels right.”
Furthermore, here’s some relative information from the Superchargers Online (SCOL) website regarding the F-Type supercharger oil, in which the author (Brian Zacuto) says....
“The oil should never burn off, it could leak, however that would be evident upon inspection. The only way to get the oil 100% out of the supercharger is to remove the gear cover and drain it. “Sucking” it out with a syringe will not get every last drop of the OLD oil out. Oil has an approximate 150K service life, changing it before then is not required.”

Anyhow, to get back on topic (Incontinent Ftype)......Statistically speaking, only one person that has actually posted in this thread so far has said they’ve had the coolant ‘Y’ pipe issue (failure) on their F-Type. However, good preventative work has been done by
jonm and
AndyH in fitting the new parts (upper and lower coolant outlet pipes), as did
Rizwan ('Y' pipe leaking from the join) in his own topic which I mentioned earlier in this thread.
