dont want to jinx my car or anything but is has done nearly 110,000 miles now, its a UK manual tt, i have many reciepts for the car but cannot find anything to suggest it has had new turbos, its still runs fine and dosent smoke...

 

my question is will regular oil changes prolong the life of them also do they wear out quicker the more often they boost???

 

thanks guys

More boost and the higher the boost = more wear yes.

 

Regular 4000 miles or so, oil changes with good quality semi of fully synthetic oil.

 

Avoid postive boost when the oil is not up to full temperate, and allow the turbo's to cool down after driving before switching off (by driving gentle for last couple of miles, or letting car idle for a couple of mins afterwards)

good diet, with plenty of vegtables, wholegrain foods/wheat.

 

dont smoke dont drink and above all exercise!.

mine should last for eternity then, because apparantley i never get into boost :rofl:

Dosen't make you live any longer. It just seems like it.

 

:rofl: :rofl: :rofl: :rofl:

 

As stated above by legarth can't do any harm.

 

Darrell

got a bottom end rattle of engiene think it is the crank shells don 91000 any ideas and how hard is it to replace can you just drop the sump or do you have to take the engiene out to do

did someone say semi ;)

u might be better starting a new thread for that question

naa this one will do fine :)

not you J1mmy, z32 tt lol

how do you da that

I hope no one reading this starts their car up and lets it idle for 10mins before driving to warm the oil up. It's as bad as not letting your turbos cool down. Get in and drive it, just don't bring it on full boost until the oil is at operating temperature.

is that because the oil doesnt circulate to the turbos when cold?

No, it's because the oil is more viscous (resistance to pour) when cold. Engine on idle produces low oil pressure. So, you've got thick oil in a cold engine with no pressure. What's it not doing? It's not getting through the oil galleries properly and not getting up to the top end. Metal against metal! Oil doesn't really work until it's at operating temperature, meaning the more you just leave it idling doing nothing, the more wear you're creating. You need to get some heat into the oil, get it moving, quickest way to do that is to drive it gradually bringing the revs up.

 

Obviously don't get in it and thrash the nuts off it as you'll screw the turbos up and do damage to the internals. But light driving is the best way to warm the oil up and keeping the wear low.

 

Makes me laugh when I hear people leaving their car to warm up for 10 minutes or so thinking they're doing the car some good, when in actual fact, they are doing the complete reverse.

well you heard it here first ;)

No, it's been said before. :)

well you heard it here first and after ;)

i only ever do it when the car is iced up, to de ice it lol.

Just to clear up.........

 

Si is absolutely bang on - Oil only has its true properties once its up to temperature. Leaving a car idling to warm up is the WORST thing you could possibly do! The amount of work the engine has to do at idle (and therefore heat generated) is absolutely minimal so the engine will take forever and a day to get to operating temperature. While this is happening metal-metal contact is wearing all the bearing surfaces out.

 

When its icy the problem is even worse, so please please use some warm water or some de-icer to defrost the windscreen (Saz I aint rebuilding your engine for free lol).

 

The oil pressure is actually higher when the oil is cold due to it not passing through the passages as easily but it is correct that the top end does get starved, due to poor flow from the oil being thicker...

 

Here endeth todays lesson lol

bravo.......bravo.........

well done old chap :)

thts handy info il never leave my car too warm up on idle ever again.
