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.

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!

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
