Hello again

Due to my job I do a lot of stop start driving what effect will this have on my turbo today for Instance I have covered 70 miles round various estates in Cardiff I usually let the car idle for about 20

it's allways good practice to let the engine idle for a while after a high speed run to let the oil circulate

because the turbocharger gets so hot in use, if you just turn off the engine without letting it cool first the oil which reamins trapped in the turbo gets kind of super-heated and can break down and crystalize which would have obvious detrimental effect on the engine. but if you are not driving very hard dont worry about it too much.

so does the oil running through it help cool it as well or did i dream i heard that

I live about 3 mins from the motorway off-ramp,

should I be leaving it to idle after a legal 75mph run (for 15mins)?

what about a spirited run over that?

don't want to be fecking the thing up when I do the run every day

drive it like a hire car then park it up smoking and smelly. job done

yes the oil cools the turbo as well as lubricating it, some turbo's are even connectd to the cooling system in the car too, so they have a totally separte water jacket

ideally you would let it cool before switching off. it is less applicable to diesel engines because these run a a far lower temperature than petrol engines.

so say icome flying down the m way then just wind it down slowly round the area near my house then go the long way round the estate would i have to let sit for a few minutes then or have i wound it down sufficiently

I always ease up for the last mile....ie; reduce speed, lower rev's, and (importantly) try to drive using no turbo boost if possible.

Once parked I let the engine idle for approx 20-30 seconds before switching off.

I only use fully synthetic engine oil in my vRS, after being present at practical demonstration carried out by Mobil engineers at the place where I work.

Also just as important as cool down is warm up....try to avoid high revs and/or high boost until the engine is up to normal operating temp.

Hope this helps

i find this very hard to do as the blower cuts in at around 1500 rpm and the car does not seem to move well at less than this if you know what i mean

anyhoo thanks for your input

When I had my vRS octy, I kept it in the garage and used the process of getting out/unlocking the garage and getting back in again as the cooldown period. Otherwise I would let it idle for a minuite or two, whilst gathering anything I needed to take with me.

After a good track session I would let it idle for a fair bit longer.
