I've just serviced mine myself! I bought these products
Fuchs Silkolene Pro S 10L £76
Fuchs Titan sintopoid transmission oil 2L £18.50
Comma Xstream red 10L £36
MANN oil filter £5
Autodelta Sport air filter £50
Oil seems expensive but the V6 does hold almost 6 litres so bought 2x 5 litre tubs. So now i have about 4 litres for topping up with in my garage.
The cooling system also takes quite a lot of filling. Think it's a bit over 11 litres. The antifreeze i bought needs to be a 50/50 mix with water so with 10 litres of concentrate i can also do our 147 when i change the thermostat this weekend
I could've also just bought a standard air filter but fancied something a bit more spicey
If you do decide to do the oil yourself make sure that you don't put a the tub or whatever you're catching the oil in too far under the sump cos when i did mine the oil shot out sideways, hit the wall of my pit totally missing my tub & then just rebounded & covered me from head to toe!!
I also couldn't get my oil filter removal tool in to get the filter off so whacked a long screw driver up through it, let the oil drain then put a smaller screw driver in the new hole in the filter to use to unscrew it!!
If it was just on axel stands i can imagine it would be quite awkward, i couldn't even get my jack under my car but luckily i have a pit in my garage!!
