Jim Bowen 1 Posted January 14, 2009 my neighbour has been made unemployed, so him and a mate have started buying cars off ebay, fixing them up and trying to sell them. They heard me start my corrado and commented on it sounding knocky when cold, i said its always done that, been like it since i bought it etc, not too worried. they have suggested using wynns oil treatment, or slick50 to lessen the noise, They chucked a can in a car they working on and its made a massive difference. Would people advise using something like that or not? I've never really liked the idea of addictives but reading the can it sounds ok :shrug: Quote Share this post Link to post Share on other sites
Dec 1 Posted January 14, 2009 Yeah, I think general consensus is to stay away from oil additives in general. Having said that; I have used Wynns Hydraulic valve lifter treatment in a few of my old daily drives and it worked wonders in reducing the valve train rattle. :| Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted January 14, 2009 Steer clear. All that stuff does is thicken the oil so much, any worn bearings etc are silenced. Masking the problem doesn't fix the problem, but for buying and selling on cheap bangers, it's fine! VR6s do knock a little when cold, but so long as it's gone within a minute or 2, there's nothing to worry about. Quote Share this post Link to post Share on other sites
Walesy 0 Posted January 14, 2009 Might be worth trying a thicker oil? Quote Share this post Link to post Share on other sites
Jim Bowen 1 Posted January 14, 2009 that was my same thoughts if i'm honest, the noise goes away quite quickly and i've never really been worried about it. i told my neighbours i'd just an r32 engine if it breaks :lol: Quote Share this post Link to post Share on other sites
PROVR6 0 Posted January 14, 2009 Like as has been said, they are just thick oil. It will slow down oil useage and can quiet up some knocks but the oil is too thick to get to all the oilways and can cause damage to the engine, especially on cold starts. They are perfect for shifting a shit motor though. Quote Share this post Link to post Share on other sites
Critical_Mass 10 Posted January 14, 2009 Sorry to thread jack 2CM, but on the subject of additives - Is ZX1 metal treatment worth using? My dad swears by it and ive used it before in the passed but never noticed much difference in running and not kept hold of the car long enough to notice any difference with the running of the engine e.g. wear.

Jim Bowen 1 Posted January 14, 2009 this is the stuff they have next door today http://www.autoplusuae.com/products/restore/index.shtml meant to be really good :lol: but i dunno, i'll probably give it a miss now Quote Share this post Link to post Share on other sites
Dec 1 Posted January 14, 2009 hmmmm......I'd stay well away from anything that says "shake well before using" for fear of particles clogging oil-ways. The Wynns stuff is at least 100% oil soluble and contains no particles....but I'd still only think about using it on a daily driver that I didn't really care about, and even then I'd do a proper oil change shortly after.

Neil VR6 0 Posted January 14, 2009 Shout me down if I'm teaching you to suck eggs but the ol' VR will always make a racket for the first 2 or 3 seconds whilst the oil works it way into the tappets. That's quite normal. Quote Share this post Link to post Share on other sites
Chris Langdon 0 Posted January 14, 2009 yep agree with the above, they are a big old lump to pump oil around, as it says earlier give it to or three minutes, i would also sugguest staying away from engine flushs as well as additive as these also can do more harm than good i.e removing particle from around the engine and then getting clogged in the oil pick up gauze, the ONLY Engine additive i would recommend is CERTEC this is the stuff Audi use for all their timing chain vehicle, stealth racing sell it.
