Proper Synthetic for 2002 GTI 1.8 Turbo

I just switched my '99 Saab turbo from M1 0W-40 to the new M1 5W-40 (yellow cap). Winters typically go as low as 0°F & summer as high as 100°F, & I run the same oil for the full year. I think this is a better application for turbos, as the High Temp/High Shear rating is a bit better.
Is the M1 5w-40 (assuming that's not Delvac) a Group IV or V based? I'd rather keep it wholly (or as whole as possible) synthetic. I cant' say I've ever seen this 5w40?
Hrmm, I see this is a Truck/SUV oil. Marketing Gimmick?

Yes, PAO (Grp4) full syn.
Yes, marketing gimmick.

Well I called around everywhere looking for the 5w40 T&SUV M1. Advanced didnt have it, autozone didn't. Wal-Mart said they didn't. But knowing these jokers, they didn't bother checking. I drove down to Wal-Mart and saw it on the shelf. Didn't buy it yet though, I'm a bit concerned that my dealer (VW) may flip out if they see it says Truck&SUV.
RL 5W40. Tyrolkids UOA's are hard to beat. Amsoil 20W50 has a lot of users and great reputation here in Oz.
That's too bad. I guess each store orders what they want. Frankly, I wouldn't hesitate to use Redline 10w30. It will protect much better than a conventional 10w40 or 5w40, which is probably what VW has in mind when they specify the oil for their cars.quote:

Thanks! I had called them last night and they said they had 5w30 and 10w30, but no 10w40 or 5w40. I asked if they could order it and they said no.
Also, I usually order my Redline from myoilshop.com (a sponser here). They have good prices.
Unfortunately they don't carry 5w40 eitherquote:

We'll see, I've still got about 1k of driving before I need to change out my M1.
Get the M1 SUV.
Mindflux, I see you live in Texas. I would be using the 10w40 rather than the 5w40. The 10wXX synthetic oil will flow at least as well as a 5wXX conventional oil at cold start-up and might give you a bit more high temp protection. I've heard that VW engines run a little on the hot side anyway. That, plus performance mods, plus a warm climate...I see no reason for a 5wXX oil.
But that's just me!

I've using the Amsoil 10w-40, 10w-30 and now Series 2000, 0w-30 in my 2002 Audi TT roadster which has the 225 Hp version of this engine. All of them worked just fine, in fact if you do a search I posted results for the 10w-40 and 10w-30.
If you can get the Amsoil 10w-40 locally, I'd simply use that. The Amsoil 5w-40 and 10w-40 use a very similar basestock blend and my oil analysis testing shows they use a similar additive chemistry as well. I'd consider these two formulations to be basically interchangable ....
To be honest, the main reasons why Amsoil came out with a 5w-40 is that some owners of high end, European vehicles are totally "AR" about sticking with the exact manufacturers viscosity recommendation. You can actually run anything from a 0w-30 to a 10w-60 in this engine, mainly depending on the lowest starting temps you are likely to see.
Up until about 1999, VW/Audi published a very comprehensive oil viscosity/temp chart for their engines that allowed numerous SAE grades to be used. Their 5w-30/5w-40 recommendation is merely a "dumbed down" version of that chart. The logic is that 5w-30/5w-40 are good compromise viscosities that can be used throughout the year, anywhere in North America. So there is a slight perference for 5w-30 over 10w-30, and 5w-40 over 10w-40 if you live in an extremely cold place.

I agree with others that you are looking for the answer to a problem that doesn't exist. Stick with the M1 0w-40, no need to mail order, and it is easily found.
If you have to try another oil, either the Redline 5w-40 (which seems to really mate well with the 1.8t) or Amsoil are great choices. I personally prefer Redline, but it is like saying that prefer BMW to Mercedes.
