Thread: Fuchs oil used in transmission service!

Everyone on the ZF koolaid come out when ever someone asks this question.

I'm after opinions of either persuasion. If enough people say "leave the Fuch's oil in, it's the duck's nuts" I'll have a think about leaving it as is because it would be easier for me. Just wish they'd given me the option of oil and I wouldn't be in this situation. They are going to refill it with the ZF oil for me anyway, just have to book it in.

The transmission shop I use has a lot of experience with the ZF HP26 and the Ford version. They aren't afraid to try things if they give a financial advantage. Their testing revealed that the LG6 gave a substantially better result than the other oils. I believe the Fuchs was one of the oils tested. I'm just stating what I was told.

When I upgraded to a metal pan the place that did it put in Liqui Moly, it drove ok but I noticed a bit of hesitation. After 6 months of ownership I decided to do a major service as my D3 didn’t come with a service history. My Indi only uses LG6 so I thought what the hell, I’ll see if there’s a difference. Gear changes are so much smoother and hesitation is gone. So I’m going to stick to LG6.

How much did they charge for the Fuchs?

Had mine done recently with LG6 at $26/litre.

My Indi always does a double flush,which is i believe the only way to do it properly.

Wow that’s good. Not that I ever worried about the cost, $20 for Fuchs $40 for LG6

The mechanic will buy the LG6 for about $24 a litre in 20 litre drums - so makes a good $15-16 on the deal. The $40 price is typical at most auto trans shops.
