After seeing a couple of auctions running with damage resulting from engine oil additives my vast experience in servicing vehicles from the 60's through to brand new $80-$90000 cars has taught me that the manufacturers recommended engine oil (grade and viscosity ie 10w40 or 10w30 etc) should be the only thing to go in an engine (with the exceptioon of some oil stabilising products for high oil consumption). Most stop leak additives can be more harmful than good.The best thing is - if it leaks top it up or fix the damn problem.A band aid will not stop an oil leak but a competant mechanical repair will.

Additives have their place. eg in a car of very little value that is only required to be patched up to keep it going for a little while longer before replacement.

Yeah I had an old Leone Station Wagon with over 300k on it, used that Nulon stuff that was like honey in the oil and it quietened it right down till clutch went at 398k.

LOL yep "stop smoke" kept the old v6 going through wof's for about 3 years. Wof time = oil change & top up with stop smoke. Never hurt the engine in any way.
The only way I can see additives "damaging" an engine, is if the under laying fault was pretty bad in the first place or they used around 90/100% additive only. OR The totally wrong additive

What about a tablespoon of Castrol R in the tank of the old Trumpy purely for the smell.!
Nothing like the old moreys diesel stop leak to get through another warrant!

Would agree that these potions simply aren't necessary in well maintained gear but for keeping a clunker going for a bit longer they are fine. You will notice that most of this stuff is created by, and marketed to, dumb Americans and other ignoramuses who have a weird and irrational disrespect for the auto repair trade and think a bottle of something will compensate for years of neglect and their own stupidity. Just like that car polish years ago that was colour matched to the paint and that you could tip lighter fluid over it and set it on fire without damaging the paint. Never go to those nasty expensive body shops again blah blah blah.

Those claims are WAY over the top. Can't even spell "vibration" right. Stay well away, if they can't afford a proper schooling in English I bet you any money they can't afford to actually engineer anything useful for your car.

Does anyone know where I can buy AT205! It is available in the US but they don't post it overseas. The writeups say it is good stuff.

I used to put a few drops in the lawnmower fuel,( purely for the smell) just to make that laborious job a tadmore bearable.
