Hi Guys

just thought i would get your opinion on this and see what ppl do,

do you warm your car before you go for a drive either in the morning or afternoon after work and so on, how long do you keep it on for, do you wait for the oil pressure to drop/heat gauge to move ......

i know the oil plays a big part in this i use Motol 4100 turbo light, please note what oil your using..

is it important to warm the car / leave it for 30sec then drive...??

i usually turn the car on have a fag then get it and drive but i dont push it till the car is warm enough...

whats your opinion

I don't like Motul turbo light oil. I use shell fully synthetic. Enough on the oil discussions though - it just goes on and on.

As for warming up - I think the best way is to get oil pressure, then take it easy and short shift until it's hot.

Cheers

i usually wait till the temp gauge starts to move, then i drive it off boost until its completely warm. and i dont give it some until the gearbox is warm too....

i use Motul 8100. my car is near stock (engine wise..), but i find that it likes the stuff.....

Yes indeed use the search button.

You will find in there where I had my motor built with forged pistons etc.

The builder told me to jump in it start the car, put my belt on and drive off slowly down the road. The car comes up to operating temp within ~2km's, which is only a minute or so.

The less time the pistons sit there slapping around the better, not that they slap much but they do slap ever so slightly.

Prolonged warm ups is probably why some of you ppls return poor fuel economy figures.

hey mate should warm up the car for about 5 mins then drive off on low boost until hot and the oil i use is PENRITE bro.

5 minutes?!?!? That's quite a long warm up. Abit too long i reckon?

I usually let it warm up for a min before i start driving off slowly. All the fluids will then start to get warmed up.

Am using Motul Turbolight. Don't think the engine likes it. Will switch to Motul 8100 in my next oil change.

^^ as in dont let the boost go past postive figures.. Thats what i meant with stay off boost.. and less than 3000rpm or so..

In general just take it easy!!

Im sure you can work it out yourself as each car is different.

And you can notice when the car is still cold..

Common sense really

I let it idle for about 30sec - 1min, just to get some oil in the head, then just take it easy, shifting before 3000rpm, in the time it takes to drive about 1-2ks the oil pressure drops and the engine is warming up 3-4ks its in operating temp.

Also if im sitting/idling for prolonged periods of time, i generally give the engine a little rev every 45 or so seconds.

Castrol Synthetic R 5w-40 as its probably the best i can get where i live. Heard they discontinued it though and replaced it with something else, EDGE i think, ( what do you know, a little search and there it is http://www.castroledge.com.au ) btw anyone know if EDGE is any good?

cheers

I was lucky enough to score an owners hand book with my car which tells you to start the car and as long as the oil pressure light goes out, drive off!

From my mechanical knowledge their are several reasons for this, one of which "cubes" covered = if the motor is cold and left to idle it can glaze your bores etc.

And another one that alot of people don't think about (or don't care because they've gutted thiers) is melting your catalytic converter. when warming up your car by idling the motor is pooring fuel down the exhaust which is still relatively cool a collects in your cat. Then as it heats up it gradually evaporates and burns inside your exhaust and heavily fuel lined cat which over time melts it! I see this a lot on the larger capacity european cars which run that much richer during warmup due to the super cold start ups they're designed for!

As is widely known through the automotive comunity " 90% of engine wear occurs during start up and warm up", so it's always best to follow manufacturers instructions as they know what they've built and the best way to look after it.

Why do you think cabbies get phenominal kms out of a motor before any serious work is required? because they (business going well) don't ever get the chance to cool down. So less wear!

I start it up and do an 8000rpm clutch dump.

But have any of you considered that no only is the engine oil cold, but so is the tranmission, diffs, transfer case etc

and they do it harder than the engine oil... remember that engine oil is under pressure - tranny and diff oil is just splashing around in there...

and PS change your tranny and diff oil regularly!
