The Pennzoil is shifting fine at -23c (-9f) which it is right now where i am. What the cSt is at these low temps i think is more important that at 40c and 100c, at these temps the unit already warmed to over 100f where it shifts fine anyway.

Pennzoil synchromesh shifted great in my Nissan 5 speed when we saw low 20s F. Its; only $9/qt in the states.

I'm interested in this. I believe the VW G 052 726 A2 specified for my car is 6.5 [email protected] The Pentosin is 7.5 [email protected] Please excuse my ignorance.. How would the thicker Pentosin flow easier than the thinner VW fluid? Sorry, just trying to figure this all out smile Thanks!
It wouldn't. crackmeup But a different gear oil with similar specs MIGHT have different characteristics and additives that work more effectively with your situation. I asked earlier...did you confirm that the shop you used actually did install the OEM fluid in your vehicle? Again it wouldn't surprise me if they used something that might be suitable, but not approved for it this could and does cause issues.

Here's some info I posted in another thread: This is 75W G052512A2. Note it is NOT a 75w-90. http://www.bobistheoilguy.com/forums/ubbthreads.php?ubb=showflat&Number=2031117 We noticed a bit of notchiness in the single digit temps and below, recently... But that signals to me that its time to change, since it has been a few years. Here is Fuchs Sintofluid 75W, which we will put in the Rabbit when it is warmer... Note this one does hold VW recommendations of: VW TL 521 71 ( 052 171 A1/A2), VW TL 521 78 (G 052 178 A2), VW TL 525 12 (G 052 512 A2), VW TL 726 (G 052 725 A2/G 055 726 A2/G 060 726 A2/G 070 726 A2) Here is Fuchs Sintopoid 75w-90, which is supposedly spec for Saab MTF 0063, and also suited for BMW non-LSD differentials as an alternate to Castrol XO/XJ. Fuchs recommends this (not approved apparently) for: VW TL 521 45-Y (G 052 145 A2) Here is Pentosin FFL 3, which is also BMW MTF-5 per the ZF documentation. This will go in the 135i MT. It carries Porsche approval and is listed on ZF TE-ML 11. I plan on doing VOAs of all these shortly.

I did reply earlier in the thread. Yes its 100% VW fluid. I bought it myself and a mechanic friend of mine put it in smile

Just from reading on Pentosin, I'd say it is a superior basestock that gives it these advantages. Anything supported with VIIs wouldn't have that low of a pour point from what I can gather. 40C and 100C viscosities tell you nothing about cold weather behavior.

The syncro between first and second is notorious, but if you change slower it won't do it, even when cold. I can only say good things about MTL and MT90 wink What code box is it?
