ive long been warned and read many a thing about additives do squat. and i generally believe it.

however i found an old xado packet my bro used on my 1.4, he did the engine and gearbox treatments ages ago (i dont think anything was wrong with engine though). its an additive of sorts but its meant to physicaly heal your engine.

i remeber thinking when he told me hed put it in "oh dear hes a dumb as i was"

but thinking back....i gave that car some absolute s**t, even a chip that upped the rev limit to 7500 and i bounced off of it frequently..... i drove it like that for nie on 3 years and it was still as good when i scrapped it and mooved onto the gti.

so i googled them a few days back and they seem very reputable now...

just wondering if anyone else has had experience with them

Agree with above tbh, use decent engine and box oil and it'll do the job just fine.

I have tried that slick 50 gearbox treatment in the past as I had it given me and it seemed to improve my old ma box but I'd imagine 99% of the improvement was from changing the oil in it. If you have it there spare it won't hurt to put it in but I wouldn't go out of my way to use it.

just thought id update on here.

so far so good. bout half way into my 30 pound treatment and theres a noticeable difference.

less engine vibration. more punchy responsive feeling engine. gearbox feels smoother now aswell. mpg seems to of improved. engiens is loads quieter, less tappy and whiney etc.

the oil pressures gone up aswell from 1.5ish bar upto 2.5 bar.

all in all im chuffed nd theres still another 500miles to go before its fully done.

how are you measuring oil pressure? at what RPM is that?

Yeah I know that low oil pressure is a bad thing, but surely having the pressure take a hike up cant be a good thing?

Oil pressure?

I have no idea with mine being a phase 3, got an oil temp gauge instead. Thought it was only the ph1's that had oil pressure gauge?

Put some slick 50 and fresh oil in my civic type r gearbox sorted it right out! Nice smooth gear change afterwards

mines a phase one so i have a pressure gauge on my instrument panel.
it only has 87,000 miles on it but it seem to of been a hard 87,000 miles.

i did an oil change about 500ish miles prior to this treatment. that didnt help or improve oil pressure. when warm it sat at around 1.5 and under load didnt really go past 4.

it wasnt an instantaneous hike up as soon as a poured the stuff in. Gradually it keeps getting better. so curently when warm its at 2.5bars at idle and around 7 bar under load.

its reverted to this higher pressure which is found on much lower millage engines, which have probably been cared for better than mine.

higher oil pressure cant be a bad thing.....? can it?

Think about it, higher pressure means there's a restriction somewhere there wasn't previously...

i understand a blockage isnt a good thing. i figure also if it was a blockage (which it isnt) it would have to a be a bloackage past where the sensor is mounted,
but isnt the pressure sensor mounted near the end of the oils travels (past moving parts)?

meaning all of the oil between the sensor and the oil pump is at a higher pressure.
isnt higher oil pressure more likely to maintain a protective film over all the parts its supposed to?

i guess the restrictions made have only been in the tolerancess of the oil carrying surfaces, especially the oil pump, all of which which should help raise oil pressure aswell.

arnt tighter tolerances a good thing?

All this additive stuff is snake oil typically using some mixture of teflon and heavy gear oil or other cheap stuff. If it really was that great all the oil manufacturers would use it. Still, the fact this stuff is still on the market shows there is a lot of money to be made from suckers who buy it.

Just use good quality oil, much better than a cheap oil + dubious engine treatment.

Oh and on Fifth Gear the other day they dynoed a VW Corrado VR6 and got it from 177 bhp to 188 bhp in a week by using an injector cleaner, changed the oil, plugs and leads and new factory air filter. Proper maintenance FTW.

ive done all that and more...... and whats left for proper maintenance is on the "wait for next payday to-do list".

just wonderering what it would of taken (time and money) to increase my oil pressure by replacing numerous worn parts?

thanks for all the replies so far

im not saying your wrong. i agree with your theory.

however can i extrapolate/question?, any psi 2 or 400, with no flow....would mean essentially the oil wouldnt move on and then heat up ridiculously fast and fail. meaning very high oil tempreture was actually the fail causing issue?

lets say flow rate remains the same between two different pressures, say 1 bar and 2 bar. wouldnt 2 bar provide better wear protection?

as long as the oil doesnt exceed its tempreture limits and cause a fail that way, wouldnt 2 bar at a slower rate of flow be better than 1 bar at a faster flow?

i cant test my flow, all i have to go on is what the little pressure gague on my dial says and how the car feels. my only real argument is that it hasnt exploded or gotten worse, its gotten better. the most compelling thing is that my oil pressure has reverted back to a much lesser millage example of the same engine (taking what beez neez said as truthful)

thanks again for the replies, ill let you know how the it goes.
