I have a 08 Jetta Wolfsburg Edition 2.0T and I am about to change the oil for the first time. I was wondering if I should use Mobil 1 0w-40, Castrol Edge synthetic 5w-40, or Castrol Edge 5w-30 advance synthetic, if I live in Florida?
Mobil 1 0w-40 or 5w-40

Man, you have a rich fantasy life!
If I had no clue, no confidence in my own knowledge, I guess I would use the manual as a guideline. It is afterall written for old ladies and other fartknockers.
TELL US HOW you come to your technical conclusions, not how you ~feel~, like a little girl.
Please go into ANY other technical forum on this site, or anywhere else, and tell people that the service manual (not owners manual) is a mere "guideline". Have you ever read a service manual? You probably think "service manual" and "owners manual" are the same thing, right? Because that's clearly what's implied by your above response.
In fact, why don't you step up to my earlier challenge, try answering questions in other technical forums? Heck, someone posted right here in this forum not too long ago asking for an oil pressure spec, and I noticed you steered clean and clear away from that one. Are you afraid of proving how little about automobiles you really know?
Now, quit the name-calling, and man up to the above challenge. Or shut up and go away.
I bet you're going to reply to this, and it's going to include at least one instance of calling me a name and/or insinuating that i'm completely retarded. Grow up
That guy still thinks that Shell and Pennzoil are two different companies and he claims he knows oil's!Please go into ANY other technical forum on this site, or anywhere else, and tell people that the service manual (not owners manual) is a mere "guideline".

Yeah...I don't think he's ever touched a car beyond the steering wheel and maybe gearshift. I bet he knows ProLine oil real well though
Oh great. Now he's going to come back in here and call us both names. I'm scared! :laugh:
wow!!! so you actually live in the deep south, working for APR.
I never knew the deep south winters got down to the single digits

Why educate people when you can make fun of them instead?
Took like 3 threads and a million times asking, but it looks like we finally got some form of credentials from the guy. I'm sure most of his technical information is correct, but it could be presented in a more friendly form for sure.
And he's an ugly bastid tooSuck it.

Redline Strait 40, ftw!
Now that we've established some credibility for you, let me answer this question.lmk HOW a 5w-40 is the "100%" choice when it's farkin' cold.
![Image]()
In short, I my area doesn't see "farkin cold" temps.
It never does, and to my knowledge never has, dropped to -30*C (~-22*F) anywhere near where I live and work. On a cold winter day, it might hit 0*F (~-17*C), but even then temps that cold aren't that common even in the dead of winter. The two coldest months are December and January, and they average 30-32*F (-1.1-0*C). Given that information, 5w-40 is fine, not far at all from the other oils on this chart. Of course, if I was in Alaska, I wouldn't be using 5w-40, but I'm not in Alaska. Also, I'd think anyone living in consistent temps that cold would use a block warmer as well.
New Jersey low temp record –34f –37c :snowcool:
Around 0f is -20c, making the 5w-40 10,000cSt, over 3x thicker than 5w-30.
I'm not sure what you intend to gain with tar-like oil.
Like I said many times, toss a q of each grade in the freezer (if your BF allows it) and see for yourself the difference.

I said average, not record. Average winter temps are closer to 0*C. Sure there are colder days, but I'm generalizing here. Exactly where and when was -34*F recorded? Oh yeah, River Vale back in 1904 :screwy:
I think I'll try the freezer trick, just for kicks. You've at least got my curiosity going. I believe a block warmer is a necessity in areas where temps regularly sink into negative numbers F, to avoid this tar-like condition you speak of.
If you think this is about my own car (the POS in my sig), you're sadly mistaken and proves that you know about as much about me as I do about youIf all this fuss is over lube for a 2.Slo, I will be mad.
I thought that was a pretty cool vid actually.
This is just silly.
I've used 10W-40 conventional here in NJ down into the single digits F in a '99 Outback and never felt it was too thick. In fact, the owner's manual allows it down to -4F.
The ASTM D-5293 Cold Cranking Simulator test is performed at -30C on 5W's, and at -25C on 10W's, so that's good enough for me. http://www.pqiamerica.com/coldcrank.htm
Running 0W-40 in the Q5 right now, but only because it was on sale and not because I planned to encounter -35C temps.
The viscosity of 5W-40 is not 10,000 cst's at 0F. Using -18C, the viscosity of Syntec 5W-40 is
is around 2,800 cSt's at 0F. Syntec 5W-30 is 2,286 cSt's at the same temperature.

Nope, try again.
Syntec 5W-30 is 10.7 cSt's at 100C and 62.64 at 40C. 5W-40 is 13.9 at 100C and 82.6 at 100C. At -18C, the 5W-30 is 2285.5 and the 5W-40 is 2798.8.
Feel free to take a screen shot and post it here.
