The G070 is for sure thinner than the G052, but I don't have the data at hand to quantify it and I didn't see it in a quick scan of this thread though it's probably in here somewhere.

Put a liter of each in the freezer overnight and shake them both in the morning.
Thanks for this. Would you happen to know the specific version of G070 you used eg my version of G052 is G052 171 A2. Many thanks.

From what I recall, the g052 you mention is the good synthetic original fluid that was in my 2001. It was not notchy when cold or hot.

Then I did redline mt90 - notchy when cold!
Redline MTL - notchy a bit when cold
Pennzoil Synchromesh - great like g052

Then I tried g070 - notchy when hot
dumped that (still have 3 qts of it new)
GM syncromesh friction modified - great stuff

The g070 has been theorized to not be a full synthetic, so it thins out when hot more than the g052 full synth and the syncromesh (which is a tiny bit thicker than oem)

Cheers for the info jimbote. Just ordered 3 bottles of Penn SM I'll post up the results after a couple weeks!
I also have a 6 speed manual (02Q). Mine will start to make a humming noise when turning the car after 35-50k on the OEM fluid (G052 171 A2).

What was your experience with the synchromesh?

It didnt help my issue at all. I ended up getting a reconditioned gearbox. One of my gear change forks had broken apparently.

Perhaps this has been covered, but I've read 30+ pages and my brain hurts.
Car is a 2001 golf with 175,000 miles. I had good luck with the $30/liter dealer supplied g052 from 7 or 8 years ago but I feel like it's time to change it. I ran a quick search on G052171A2 and I came up with a Febi product that's only $10/L + shipping. Indiana goes from blazing hot summers to subzero winters, so I need all weather smoothness. Has anyone tried the Febi product? There is also a Fuchs alternative that's about the same price. Anyone? Thanks

Ok ok, probably asked millions of times, but what is the correct oil for my manual seat exeo 2.0tdi, 6-gears. Asked the dealer and he said 170€ for the oils+work, sounds rather expensive to me. I tried to look for the correct oil, but got mixed answers. Any help much appraciated, i really want to change the oils.



This sticker should mention what transmission i have? None of those codes are transmission?? :confused:

I just went to VW for gear oil for my 02 and they gave me G60? I see no mention of that in the thread; any ideas if it is correct for my 02J?

Fluid Capacity

Just did Manual Tranny gear oil change 2003 ALH TDI.

Manual says it takes 2.1 litre , or 2.0 quarts.

fluid warm, let drain for half hour.

took about 1.7 litres not 2.1.

anyone know why this would be??

ps used VW OE gear oil.

You could have been a bit low or at an angle.

For help in lubricating 5th gear, I used to overfill a bit quickly adding the plug.
With the 5th gear oiling mod it's not needed.

Steve, you might also note that liters are larger than quarts, so 2.1 liters is 10-15% larger than 2.0 quarts.

A little less than 2 liters is what people usually find. The only way I've found to get 2 liters in is to have the front end high, pour all of it in, then put the plug in before letting down, as robnitro explained.

Another item to note is that a dry, new transaxle will take more fluid than one just drained. This would be due to the oil that sticks to all the surfaces of the internals (not an insignificant amount, by the way) and on the 02J, the 5th gear volume that has no drain.

Cheers,

PH

So after posting that I think I read further back that this oil is basically the same thing? Anyway filled the box with it and am pleased to say it's pretty lush, much smoother gears now.

Same here! I just found this site and thread, lots of good info but wondering if it's possible to get a little carried away looking for the "right" lube.

My experience started in '83 when I bought a Ford Escort a when draining the tranny discovered the factory fill was ATF. Did some inquiring, yup that's normal.

At the time I had a VW Rabbit that was extensively modified and putting out around double the stock power. Good test I thought and in went the ATF. What a difference in cold weather! And zero shifting problems in hot weather. No reliability or wear issues found. I actually still have that car.

So Dextron II has been my fill of choice ever since with the only problem encountered is the tendency of it to find weak seals and gaskets and seep a bit.

It's not about getting carried away, it's about getting something that works for you.

For me I decided to research with the notion of getting something that would work w/o having to spend the time and money to be doing a bunch of fluid changes trying to get the best fluid. And it's pretty clear what the top candidates are for 02Js (as well as what NOT to use- I have yet to read anyone that's happy with VAG's G070).

Polo 2006 BNV JCZ
Hi guys,

I actually read most of this thread. I either missed it, or the info was not clearly stated. I have a 2006 Polo TDI BNV JCZ transmission. In 2007-2008, the car had a service action (as they call it), and they replaced the gear oil. Part number used: G052512S0. As I found out, this is an internal part number. We can buy it as G052512A2. At around 100k km, I bought gear oil from the dealer - part number G070726A2. At around 200k km - same part number. I didn't pay any attention to the part number. I thought they will sell me what the car uses...
What do you think I should buy now: G052512A2 or G070726A2. Does anyone know for sure the difference between the two?
I'm thinking about this because I have 2 different noises from the gearbox:
1. something like "hhhhh" when under 0C, at first start in the morning. it stops when the clutch is completely disengaged (everything in the gearbox stops). if it's only half, sound is still there. after 5-10 min of driving, the sound goes away. If over 10C, sound is not present.
2. after wellwarmed up gear box, when over 20C in the air, just before the car comes to a complete stop, so 1-2 km/h, it makes a knocking sound but not continuously - it's like the sound can be heard every 45 degrees of the wheel. car can stop and the noise may or may be not present ( depends on where the wheel or driveshaft stops). if the noise is present, it goes away if trying to engage 3rd or 4th gear without pressing the clutch, or if turning the steering wheel !! it also goes away gradually if pressing the clutch. if the car stops and the noise is not present, I can be heard if turning the steering wheel.
if there was a gearbox issue, why is it affected by the turning of the steering wheel?
the car has no abnormal noises when driven: hard accelerating, hard decelerating, turning hard uphill, breaking hard downhill and turning.
someone gave me the idea of checking the tapered coned bronze ring from the flanged output shaft that comes out of the diff, and when doing so, I will put fresh gearoil in. now, what should I use G052512A2 (the service action oil) or the G070726A2 (the oil that the dealer would sell me now according the VIN) ?

Thanks!

just put in G052512A2. Obvious smoother shifting (25 Celsius outside) cold and warm. I expect the lever to move like through honey in the winter for the first 10-15 min but I won't mind.
When I took out the filling plug (car leveled), about 100-150 ml of oil bursted out, so that confirmed my "suspicion" that I did overfill the gearbox, which is good :).
When refilling, I tilted the car for about 10-15 degrees, and it took about 1.8 - 1.9L of oil before starting to overflow. Then I put the filling plug back in quickly so I guess I overfilled it also this time.

difference between G052512A2 and G070726A2: G052 seems to have a bit darker colour. At room temp, to the naked eye they seem to have the same viscosity.

I have yet to read anyone that's happy with VAG's G070).
I've been running the G070 in my '02 for the last 60K at least. I just rolled 300K miles, and she still shifts great. It shifts much better when it is cold (0F or less especially) and all-around I like it better. The only "issue" I notice is when fully warmed up, I will will get a little bit of grind when shifting into reverse if I do it to quickly after depressing the clutch. If I wait an extra second to let the input shaft spin down, it won't.

As always I plan to use the Amsoil product. As always, if it causes a problem you all will be the first to know.

Makes sense that that thinner fluid (which the G070 is) will work better in your colder climate. If you haven't tried Pennzoil or the AC Delco fluids I'd say try them as you might find that you have ZERO issues (warm or cold). BTW - I missed the mention of what fluid you'd replaced. Keep in mind that in almost all cases a fresh fluid will always be better than old fluid.

My 2001 finally failed at 450k miles 5th gear went out and I never changed the fluid it was original. Every bushing was worn out and sloppy as hell. I put a junk yard 130k tranny in it which feels so much tighter, but I put Mobil 1 fluid in it and it grinds like crazy. I'm going to pick up some OEM stuff this week and give that a try. I'm kicking myself for not just leaving it alone from the junk yard, but if something went wrong I'd be kicking myself too.

For everyone out there looking for less expensive option for the factory G 052 171 A2 02M/02Q transmission fluid, I've finally come across a few good options in my search on what oil to put in my 02M transmission.

I also think I've figured out who makes the factory fluid for VW/Audi and that would be Febi/Bilstein.

Anyway here are the less expensive options I've found:
FCPEURO @ $8.22/L for Febi/Bilstein Oil
Warehouse33 @ $9.77 for Febi/Bilstein Oil
PelicanParts @ $10.75 for Febi/Bilstein Oil

This is for you guys in the UK:
AutoDoc @ 9,92 Pounds for Febi/Bilstein Oil
AutoDoc @ 11,80 Pounds for SWAG Oil
AutoDoc @ 13,61 Pounds for Meyle Oil

Here's another option that people have mention they thought this company may be making the OEM fluid for VW/Audi's 6 speed transmission oil and that would be Fuchs.
https://www.carid.com/fuchs/titan-sintofluid-fe-1-l-sae-75w-80-synthetic-manual-transmission-fluid-mpn-g-052-171-a2.html

And last but not least, I'm going to giving Liqui Moly High Performance Gear Oil (GL4+) SAE 75W-90 a chance and see how it does in my transmission with a Wavetrac differential, even though Wave trac recommends Motul Gear 300 75W-90

Believe it or not, I was able to find the Liqui Moly gear oil for only $10.91 on ECS Tuning. :eek: https://www.ecstuning.com/b-liqui_moly-parts/manual-transmission-differential-fluid-75w90-1-liter/20012~liq/

Hopefully this will help some people out in the future and I believe this will also work for the 5 speed guys out there as well, since I see it lists G070726A2, 0019892603, G060726A2, G052512A2 on site as what this oil will cover.

I'm glad I could contribute and hopefully it saves others some money in the future by not having to buy OEM fluid from the dealer, since last I checked it was in the $26 range. :eek:

That BG Syncro Shift II looks like a good option as well. Where do you purchase it at?

I’ve used Millers trx synth gl5 and gl4 in a 6 speed Audi a4 b7 and a passat b5 5 speed both manual in the UK.
Both change gear really well and slightly better fuel consumption.
I chose it based on the viscosity in the product sheet was close to what has been tested here.
In the uk on ebay you can get 5 litres for less than £40 so its quite reasonable too.
Great stuff in my opinion.
Cold shifting was mush better than original altho original had about 160,000 miles on it.
