Sorry I did 29 ft/lbs in the end, just a typo.
Interesting this oil change went really well. If I had a 4 poster I could do it in 45 minutes as the 'oil filter flap' in the under tray is just two small screws. Problem is it opens 'away from you'. So. I opened up about 8-9 under tray nuts till the oil filter was exposed. Then a simple sin off- spin on.
The total cost was £21. 71p. Yes really. It was Euro Car parts internet on a good weekend at 40% off.
The oil is the very very best, i.e. Shell Engine Oil (Helix Ultra Professional AG Engine Oil - 5W-30 - 5ltr) plus a Mann oil filter (made in Germany - We all love that really).
Unlike my previous oil change, I lifted the car, did the oil change and then, lowered it before starting the engine. All was well. Starting the engine 'in the air' = the air suspension drops to 4 inches above the floor. Very scary.
Noticed the air cleaner is a tad dark so decided on a whole service package from:
https://www.ebay.co.uk/itm/Genuine-Lexus-Service-Kit-LS430/172714797592?fits=Model%3ALS|Cars+Type%3A430&epid=2228869058&hash=item28369aaa18:g:8M8AAOSwcLxYCMIU
So, say plus say £20+ for Shell oil, i.e. One can service a LS430 each year, (actually slightly over servicing + the bits) for £80.
That seems good to me.
Have not 'changed oil/serviced' etc, on a car for ages. The satisfaction of 'doing it properly' is wonderful.
