what oil addidtives do you use ?

[stevie 4]

my scoob is getting on a bit now my93 so iv been thinking of using an oil additive to help prolong the life of my engine i have seen this which i am thinking of buying http://www.ksealit.com/index.asp?function=...CT&productid=33

but wanted to know what other people are using or would recommend

[chris_c201]

Don't quote me on this and i'm sure someone more technically minded will come along but...

I would think you are best just to use a high quality oil, the right grade and change it regularly than use an additive... again thats my understanding but i'm sure someone will have a more technically minded view....

[diffbuster]

from everything i have read you should never use additives as they break down at the excessive heat in a scoob engine.

[dipsy]

I used oil additives in the classic my00 uk turbo made no difference just a waste of  money.Stick to good quality oil and change the oil more.

[the squiggle]

Especially stuff like Slick 50, better urinating in the sump

As said above run with a good quality oil and change frequently

[ally-b]

I believe that if these products were any good then the car manufacturers and race teams would use them.

I concur with those above - good oil and regular oil and filter changes are all that your engine requires.

Dont use oil additives they can wreck turbos.Was recently sent a service reminder from a dealer and they wanted to use an oil flush on turbo engines.They should know better.

HI m8 a little while back i posted a group buy on pure teflon additive  I used it in my 400+ brake cossie  rally car in scottish championship  in engine  -g box in diff front and rear teflon greases in hubs etc I now use it in my 330 bhp scoobie track car ITS THRASHED beyond belief  see pics of last sat/sidc day GPmotorsport?gpvalet services  dont listen to pub experts listen to people that have proved it works ---it wont damage a turbo it wont degrade  it wont melt in your sump its made by du-pont and it is used in more severe applications than any car could put it to  inc/jet fighters airliners  its military app for use in helicoptors   /tanks   / hope this answers your question geo[:@][8o|]

The only one that I have used, and can recommend, is Forte seal conditioner. If the car sits in the garage for longer periods of time between use then this stuff stops yer seals from  hardening - can also reverse the degradation to a small degree - just as long as they're not completely stuffed to start with.

Hi scoobie dougie this is not classed as an lubricant its an additive for softning seals but if it works it good , Being in the motor trade for35 years and having  rally experience of 22 years  in total, high performance driving/ engine building ,rally car prep i have had good and bad experences ( learn by my mistakes or somebody elses)of addives one being slick 50 , dont rate it  2% regraded teflon rest carring fluid  You need 100% teflon to bo the job right  PTFE  POLY  TETRA  FLOURA ETHELINE  simply little balls of plastic that are suspended in your engine oil -any oil except auto- matic gear boxes because its a friction reducer  now the science  bit  when an engine is  stoped the crankshaft sits down on its bearings -camshaft /same when start up happens ,oil pressure does not happen immediately,  the bearings can be lightly scuffed (most engine wear takes place from cold start up) all parts of the engine inc/turbo .Teflon sits between the bearing and the shaft surfaces and takes up the space between giving the oil pressure  time /to build up Same happens on switch off -oil pressure drops turbo still spinning -bearings lubed The exhaust pulses slow the turbo down to tick over and allow thermal dissapation(thermal shock) during this period turbo is protected. I use it in both my cars WRX0300 and track car and fiesta dervy ONE thing i dont  like are oil flushes /not good for cars with hyd tappets /only use as a last resort if oil is changed reg/ i ts not needed /if i had to use one i would flush afterwords with  an engine oil sorry to go on but its something I feel car -petrol heads should know   GEO[{]

cheers for the replies guys. seems to be a bit of a disagreement about weather they work or not has anyone actually had engine damage caused due to an oil additive.

cusco I touch goats

If it was so good then Subaru would have designed the engine to contain teflon, or ptfe

The properties contained in a good quality oil is more than sufficient to protect your engine and agian if it was such a god send why dont Mobil, Silkolene and the likes put it in thier oil

All from a pub expert

What works for a Cossie does not mean it is suitable for a Scoob

 

[Adam Kindness]

an engine is an engine

[the squiggle]

Agreed an engine is an engine but the flat 4 design of the Subaru throws up different problems to an in line 4.

One thing to note about the Flat 4 is the Big Ends are smaller in diameter than a Saxo 1600 but have to cope with a lot more stress than a N/A Saxo

All my own humble opinion

I would not use any additive if i am using a decent viscosity and make of oil

[col666]

O/T but did you see the saxo driver in the paper today? got caught doing 131mph[] must have had a few mods!

[cusco kid]

Some of you guys are missing the point  as described already the teflon is mainly there to pre lube before oil pressure comes up to its maximum  and also after oil  pressure drops the plastic balls take up the space between bearing surfaces reducing friction and wear ---- i have had engines that developed small end knock and have been cured by adding teflon  my track car was baulking 2nd gear --cured ,guess what? yes you guessed it teflon but a different grade /larger  molecules made for g/boxes and as stated already  330 bhp subbie running on teflon engine addivies scuddied stupid -7000 rpm in every gear  regards  non drinker geo[H] well maybie a wee drambuie now and again[6][A]

[Oilman]

We do not recommend oil addatives, they are already there and the quality of the addative pack generally is higher in line with the oil.

Had many opportunities to sell them but just not interested as I've yet to read a decent chemical report on one.

Hi simon tell du-pont there ptfe is no good see what response you get , the spend millions on research  for millitary use in jet aircraft , army for tanks ,helicopters heavy engineering companys etc and if its good enough for non stick pans its good enough for me I have many years of use of teflon -rally cars ,police vehicles, road cars ,regards GEO[:|][H]
