RedBarediver Posted December 27, 2019 Report Share Posted December 27, 2019 Hi all, When I was younger I always used to treat my vehicles with Slick 50 and was wondering if anyone has used it in a Boxster?Alternatively if anyone thinks it's a really bad idea can you let me know why you think so? I use the car quite infrequently and mainly on weekends. Whenever I start it up there's always a little puff of smoke on startup and I can hear the engine is a little dry for the first few seconds. It settles down quickly and on the rare occasion that I start it two days in a row I don't have the puff of smoke and the car starts as smooth as silk. I am thinking that if I can add Slick 50 it may help prevent some unnecessary wear (and my previous vehicles always used to feel a lot smoother with it in). Thoughts?

RedBarediver Posted December 27, 2019 Author Report Share Posted December 27, 2019 Never mind. In my research I found this: http://www.fordscorpio.co.uk/snakeoil.htm I reckon I'll stick with a decent synthetic oil rather than add anything.

Greenman Posted December 27, 2019 Report Share Posted December 27, 2019 Interesting link that. its not anything I’ve considered in the past 20 years or so to be honest (a Porsche or not), it did seem to be all the rage in the 80s but I think modern synthetic oils somewhat alleviate any perceived need. But that link does seem to imply that most would cause more harm than good. Link to comment Share on other sites More sharing options...
Nobbie Posted December 27, 2019 Report Share Posted December 27, 2019 Interesting link and confirms my thoughts on most of these additives. The key argument being that if they worked, surely the multi billion pound oil companies would have already used the technology, especially with the push to extended service intervals. Interesting regarding the adverse affects on bore score, don't try this on your 3.4 @bally4563😀 Link to comment Share on other sites More sharing options...

½cwt Posted December 27, 2019 Report Share Posted December 27, 2019 Oil puff is common on horizontally opposed (or 180° V if you prefer as there is a slight technical difference but don't ask me what it is) engines as the oil has no gravity to clear it from the cylinder bores when it is not running so stays on the bottom side for the bore, hence a small amount of oil burn. Mine rattles somewhat as the lifters fill again if it has stood from more than 4 or 5 days. I think I have a slightly sticky lifter as some times there is a reduced rattle for a while longer after starting when stood for a week or more but I'm not about to take the engine apart for that.

PaulQ Posted December 27, 2019 Report Share Posted December 27, 2019 People still buy it because apparently it makes their engine run smoother and they get slightly better mpg. A bit like super unleaded then....... 😁 Link to comment Share on other sites More sharing options...

That does have supporting evidence even as basic as complying to a higher industry standard that states it has more knock resistance and therefore allows an engine to be tuned differently with more ignition advance of higher compression thus yielding more power. Then it is just a matter of whether it is cost effective and that is down to personal choice. Link to comment Share on other sites More sharing options...
