engines are allot more advanced theses days since your flat cap rover days lol, hence Terraclean for newer engines.
if your a big Motorway driver i seen no point as this TC is really ideal for more short journey people as that is were i am, it will be a while before i have it done again as well as i see no need at the moment.
VE engines, that's the height of technology, now it's all going backwards lol
My car's missfiring, car wont start, need a new cam, turbo blew again etc etc. Sod that pile of poop!
