So in other words:
No one knows whether G52 is okay in a pre-2005 Jetta/Golf/Beetle?

Yeah, that is TDitech's basic assessment, too.david_594 said:but when it gets cold it feels more like a frozen block of butter.
TDImonkey said:I'm looking at doing the 5th gear swap tomorrow, and wanted to put Redline MTL in. Couldn't find it, and waited too long to order it (d'oh!). I ended up getting Valvoline 75W90 full synthetic. I don't see it mentioned anywhere else here. Does anyone have any experience with it?
Thanks!

SUNRG said:FWIW - i had Redline MTL tested by my local CAT fluid analysis lab and it came in at 10.8 cSt (very close to the claimed 10.6). and, after my very crude freezer testing i feel confident that Redline MTL flows faster than OEM G52 in below freezing temps. so...
the only question is fuel economy... is G52 the ultimate fuel economy gear oil???? (due to its super-low viscosity at normal operating temps...)
- Redline MTL is thinner / flows better in very cold temps than G52, and
- Redline MTL is thicker / theoretically protecting better in hot temps than G52
i'm going to give Redline MTL a try and see what happens...

Volkswagen TSB 34 01-01 states that in certain models a humming sound maybe caused by a spider gear contacting a one-piece thrust washer and that replacing the existing gear oil with G52 171 A2 gear oil will eliminate this noise.
LOL - this is sooo true. my shifting was fine and fuel economy very good but here i am tinkering...Again this a great exercise, but since there are no controlled conditions or “blueprinted” cars to use as a control group and without reproducible results do I see once again “a solution in search of a problem” ……………
That's what I wanted to hear. When I get to doing a transmission fluid change I'll switch to Redline MTL. I've been using it in my 240D and I like the way it shifts and I also like what I've read about it, namely the balanced friction coefficient that's supposed to optimize shifting. My Jetta shifts fine with the factory fluid, but when the transmission is cold and I'm rolling backward it takes some effort to get it out of reverse.SUNRG said:FWIW - i had Redline MTL tested by my local CAT fluid analysis lab and it came in at 10.8 cSt (very close to the claimed 10.6). and, after my very crude freezer testing i feel confident that Redline MTL flows faster than OEM G52 in below freezing temps. so...the only question is fuel economy... is G52 the ultimate fuel economy gear oil????

thx.
Peter - i'm new to gear oil lab analysis, but i had my G52 lab analyzed after 43k+ miles and the CAT fluids lab manager said it looked fine and there was no need to drain it (other than my curiosity and interest in experimenting with different gear oils). Have you had G50 lab analyzed, or seen G50 / G52 lab analysis comparisons?LessIsMore said:G50 = excellent protection, shifting & durability.
G52 = rapid wear, inferior shifting.
there is minimal strain on the lube when shifting. the ring and pinion gears are always turning, mile after mile the same amount.LessIsMore said:As for comparisons, take into account that some people might shift 20 times to drive a hundred miles. While on my country roads, I shift a hundred times to drive 20 miles..
there is an internal magnet on these trans-axlesIf you drain a gear box and observe swirls of glitter in the oil, are you learning the same thing that an analysis will tell you or something better. IOW, does the analysis detect these large particles? .
who knows what the fill actually was...certainly not identical lubes and conditions.If one oil drains black and another drains amber, should this info be treated as anecdotal, and therefore inferior to oil analysis? .
unusual wear from syncro rings is caused by fast shifting with an occasional grind here and there.LessIsMore said:Do sycro rings wear? Copper goes to the oil.
