Ok so my old man was changing his diff fluids today and as he was putting the last bit of oil in his front diff he noticed some lumps come out of the bottle.so i look in the bottle to find this hard dirt like substance in the oil so i looked at all the bottles and noticed every one had this.

In my experience with diff fluids an oils in general I've never seen this crap! Another reason i will never put a lucas oil product in my jeep!

 

Was not happy with their transmission oil either. Put it in and two days later my tranny went out.....

 

logically it must be the fluids fault. its not like you put their fluid in a new 0 mile tranny that had been fully tested. I usually blame my wall power too when my electronics break.


OP sorry you feel that way and got a **** bottle quality control is never perfect. Iv never had a problem with Lucas but maybe Iv just been lucky. the fluid in that pic looks super dark maybe its just the light though

 

The thing is it wasn't just the one it was in four of the other bottles we put in so really not happy about this

Also sry for the bad pick

 

Heres a better pic of whats in the oil

 

It wont hurt anything been using it for yrs with the chunks.

 

Test out their warranty/ customer service. Tell them about it.

 

i use that diff fluid but i've never had a problem. how old is it?

 

Ive run there stuff for yrs in my big rig not one issue.

 

Just got the stuff last week
And the only thing that could be a date on the bottles are this

 

What? oil in general, couple of million years......

 

I personally have not been made a fan of Lucas yet, but this gives me a reason to wait and see a little longer.

 

Lucas is bottom-shelf product, with a high price tag.

 

I use good 'ol standard 80W90 dino oil in my diffs.

Never had one blow chunks or wear out yet.

 

It's cheaper than royal purple !
