Slightly moving on from which fuel to use, does anyone rate/use additives you see for sale in places like halfords... decoking/fuel cleaning/coolant enhancing... the list gos on... just wondered if they are worth the money or if using optimax does just as a good a job?

 

Be interested to find out guys...

anyone use any of these products?

i use fuel system cleaner & engine flush every now & again. i only use trade products & wouldnt use the crap sold in the likes of Halfords tho!!

notice any difference with them? or is it more a peace of mind thing than a feeling through the car

it is more peace of mind really, tho with an engine flush the fresh oil certainly stays cleaner for longer :)

any milage limit to using a decoker/engine flush, thought id seen somewhere not to use them after the car had done more than 60k something to do with engine wear.. or is this just rubbish?

nah, mines done 120,000 miles now! it *can* show up problems that were peviously masked if the engine is in poor condition.

 

if the rings/bores are worn then the coating of carbon underneath them can help keep the compression up, after flushing the carbon gets removed & if the rings or bores are really that knackered then it will allow the rings to sit further in on the pistons. iv done hundreds of flushes on cars over the years & have personally not had a problem. it can happen tho

should be ok on a mid 80,000 milage car then....
