stevie 4 Posted November 16, 2006 Posted November 16, 2006 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 Posted November 16, 2006 Posted November 16, 2006 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 Posted November 16, 2006 Posted November 16, 2006 from everything i have read you should never use additives as they break down at the excessive heat in a scoob engine.
dipsy Posted November 16, 2006 Posted November 16, 2006 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 Posted November 16, 2006 Posted November 16, 2006 Especially stuff like Slick 50, better urinating in the sump As said above run with a good quality oil and change frequently
ally-b Posted November 16, 2006 Posted November 16, 2006 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. Al.
billyboy Posted November 17, 2006 Posted November 17, 2006 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.
cusco kid Posted November 17, 2006 Posted November 17, 2006 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|]
ScoobyDougie Posted November 17, 2006 Posted November 17, 2006 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. Cheers
cusco kid Posted November 17, 2006 Posted November 17, 2006 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[{]
stevie 4 Posted November 17, 2006 Author Posted November 17, 2006 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
the squiggle Posted November 17, 2006 Posted November 17, 2006 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
the squiggle Posted November 17, 2006 Posted November 17, 2006 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 Posted November 18, 2006 Posted November 18, 2006 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 Posted November 18, 2006 Posted November 18, 2006 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 Posted November 28, 2006 Posted November 28, 2006 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. Cheers Simon
cusco kid Posted November 29, 2006 Posted November 29, 2006 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]
