Nulon Oil In The Zf

[Adam]

So you've now got a mix of genuine oil and Nulon oil in the box?

Yep. just like everyone that's changed it, to varying degrees. I'll get more and do it again next service, and should be 'refreshed/diluted' enough.

no it should have been flushed this takes 10-12 liters .then it would give you a better idea

So is a flush basically dropping it twice then? (given 5 L came out and went in). You'd hardly still be getting it all out anyways, just diluting it further. So basically what will happen next service. I would imagine given the system holds 9-10L? That one would have to run 20L through it, maybe 4 drops to be fairly certain the bulk of oil is mainly fresh?

The oil that came out wan't 'new' autotrans red, but wasn't at all black, more brown, it had a sent to it but certainly no burning smell etc.

But sure ideally one would want the oil to be 100% new, it's obviously just a labour/time thing + large quanity of oil combo to get there.

I figure pan had to come off in mine anyways (warranty on pan gasket weep), but that's all they covered, so for a trip to supercheap + steal pan/filter from motospec's (tried ringing Hiro but was out of time) I've for 50% new oil that's probably a bit better, so now is 1/2 the age (sort of) diluted to what was in there. Either way it's better, and in future I just need a filter & some Nulon.

it would be better , but a proper flush is done using a tool that forces the new fluid through the converter and cooler ,removing nearly all the old fluid.

[Spoony]

Do take note though, from the calls I've made around the trans shops, they generally seem not to 'flush' the system unless the oil was stupidly black/dirty (I guess they'd then tell the customer this) or if you request it at added expense. So based the prices I've seen many people get quoted on this forum, most/many are quitely likely only getting what I have.

Some use the genuine stuff (and is reflected in 30-40% more cost for the job), others full syth aftermarket such as the Nulon, Transmax etc.

Anyways at least it seems Nulon will work fine, I'd say even better if 100% flushed so no issue using (thus far) in the ZF. I'm sure you'll hear from me in tears if there is. haha.

good to see how it goes , Usually need to request a full flush job . last time I did the BA I bought my own oil and payed about 2 hrs labor at a trans shop for the job.

[Spoony]

yes certainly the full proper way to go but given 99% of ZF's out there either have old oil and are still probably going, or even if they think they've had a full service is not more than a 'fill' service. It'll get there, just maybe in a few 10k's or driving lol. Needed coin for OS holiday otherwise would have. Was hoping warranty (extenced Swann) would cover oil/flush etc but fail!

I wonder what Fraud would do underwarranty, re use the oil to no doubt as its 'specified' as 'for life'.

[Adam]

It makes sense to do a full flush when changing between different oils.

Flushing a trani is as easy as this: Remove exit hose from train at trani cooler I.e. the tempreature transfer cooler mounter on the side of the block. If unsure which line is which, remove both and place a clear hose on each then place the clear hoses in a bucket with measurement marks on the bucket. Run the engine until bubbles show up in the clear hose, then turn off and add same amount of fluid measured in bucket into the trani. Then run again. Keep doing this process until you are happy with the colour of the fluid. Then put hoses back on trani cooler.

Im not saying for anyone to do this, but it is basically what a trani flush is all about, alot less complicated and mysterious that what we are led to believe
