There are loads of engine oil additives on the market these days, claiming to reduce friction and engine temperature and increasing performance and engine life. Have any PHers out there got any first hand experience of using engine oil additives? Do they really work? Are they any good?
I'm thinking of trying some in a mildly tuned Rover 3.5 V8 so any advice, comments or recomendations would be appreciated.
Many thanks
Bill Bob

Bill Bob Waste of money !! unless you have a worn engine high oil consumption some of the stuff thickens your oil and helps a bit!! manunfactures spend milions formulating oil and engines run for 100s of thousand miles on it now ,IMHO you are far better changing the oil more often and fitting an oil cooler to add reliabilty and engine life..

Hi Powerstroke, thank you for your comment. Is your view based on first hand personal experience or on the same conflicting data and information that I have read in motoring magazines and the internet?

Personal expirance from 30 plus years of messing with cars trucks motorbikes plant and some motor sport as rally mecanic and some racing myself, realy it is about avoiding metal to metal contact with a film of oil in bearings and on cylinder bores, most engines in ok condition are fine as long as there is clean oil something close to the recomended grade at a safe temprature at about 10 psi or more per thousand revs.. These claims of redusing friction!!! my question is if there is all this friction without useing some adative why dosent the engine wear out in 1000 miles or 5 ????? and alot of vehicle and oil manufactures warn against using adatives as some of the ingredants may not mix with stuff already in the oil so it might even be detrimental to your engine !!!!

Oil thickeners work by thickening oil... Does what it says on the tin.
Slick 50 'works' by coating parts in PTFE... I've not seen any proof that this actually does what it says. Has been proven to cause problems by blocking oil filters. reports of legal actions against the manufacturer in USA.
I've heard reports from personal friends who swear by Xado, which is supposed to coat hot moving parts with a ceramic coating. There are many threads on the interweb showing why this does/doesn't work.
My mechanic, who has always been sceptical about 'snake-oil', has tried Forte engine flush and fuel additive. Before and after tests on an old Ford gave very significant improvements in compression and emissions, but on an old engine with unknown history this may have been down to having a service.
On the whole I think the consensus of opinion from non-involved, clear minded people is that the main purpose of these additives is to generate revenue!

Have used Wynns ,STP AND Forte first 2 on my personal stuff Forte as asked by the boss where I used to work .On older engines they all 'work to a greater or lesser degree and STP certainly kept a well loved but well used 1275 S A series ruunning till I could a fford a set of brgs etc .There are people out there will say that the stuff is s--t- but it worked for me! no experience on a new engine , never could afford one!

Thanks to all for the thoughts and comments.
I think I'll go for some quality oil and give the additive a miss.
Thanks again.

Correct decision!
So many people buy cheap supermarket oil and then spend stupid money on non-working additives!
A decent quality pil is all you need!
