5W30 is actually recommended for colder climates

 

I think that your oil is fine for about 3k, but as the others have said, it would not be wise to leave it in for an extended period. Turbo engines are very hard on oil. Turbochargers spin very high rpms, like 10k - 20k, so the bearings in them generate heat like no other engine component. That's why Mitsubishi advises Evo owners to cool down the engine after hard or uphill driving - to cool those turbo bearings down so the oil doesn't burn on them and ruin them. That is why turbo timers were invented. If the engine is running, the oil keeps moving acting as a second coolant and the moving oil doesn't burn.

 

I'd stick with 10w30 anywhere south of Maine...

 

10x30 mobil 1 ext. or not all year long. just use it and stop worrying i think mitsubishi, corvette, and exotic car companys know what they,re doing when it comes to recomending and using a certain oil from the factory

 

So what if you do drive your car hard and dont let it run a little after will it not put out as much boost, or will it totally kill it, or just ruin its life, or all of these?

 

it's a simple thing.

if you can change at 3000miles, it's good. You get some fresh unbroken down oil in your car, super.

If you go over 3000 miles, it's ok, it's not going to blow up.

I wouldn't go over 5000miles though. But I have, and nothing happened. Oil burns a lot by then, you refill it or change it if you can.


The TT is for older engine that rely solely on oil to cool down. most modern day turbos are water and oil cooled. It's recommended to cool it down before shutting it down, but it's not going to burn the shaft out if you don't.

I'm sure all these things will help car last long. But you shouldn't go crazy because you went 1 mile over 3000 mile on your oil change, and you shouldn't go crazy because you shut your engine down after a normal driving.

 

the bearings get hotter without a cool down after hard running and boostin. and that turbo spins more like 100,000 rpm,s not 20 -30k. if you let your car run or get a turbo timer what your doing is maintaining oil to the turbo bearings during turbine slow down and keeping them cooler and lubed

 

what if you shoot yourself in the head? will you die or will you survive?

have a little common sense dude, you've heard and read why you need to cool your car down after hard driving, so just do that and your car should last you a long time

 

I use only Mobil 1 regular synthetic. I change it every 5000 miles like clockwork. I'd say that I have to add a little bit in between oil changes about 50% of the time. Hard driving causes more oil to burn. Also, I add about 4.2 quarts at each change.

 

Royal Purple 10w30 is the shizzle. Get it at pep-boys!

 

I use 10W-30 and change it every 2,500 miles. If you gonna drive hard, you should change it at least every 3,000. People that track their cars usualy change oil after every event.

 

lol

 

I Use The Mobil 1 10w30 Ext, I Have A Qt. In My Hand Right Now And There Is Nothing Anywhere That Says Not For Turbo Charged Vehicles Or Anything Like That

 

There's lots of Mobil1's now. And some do say not for turbochared engines. I just don't remember which one.

 

Your Right But Not The Mobil1 Ext.
