## Customer Reviews

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good stuff and not available just anywhere. I shall always want to have some in stock.
  

*by J***H on Reviewed in the United Kingdom on 2 July 2018*

This has helped with freeing off a seized 1933 engine. It was recommended by the manager of a Halfords car repair / service centre but it, curiously, not something which Halfords Retail stock!!

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Great product.
  

*by D***M on Reviewed in the United Kingdom on 16 July 2015*

Purchased on the strength of other reviews primarily, and has turned out very well. It works! I had some old and totally immovable radiator valve nuts...but no longer! Fairly pungent when used in one's bedroom...the ball & chain was not happy...but a small price to pay methinks. Recommended.

### ⭐⭐⭐ 3.0 out of 5 stars







  
  
    Did not work for my stuck filler plug.
  

*by D***G on Reviewed in the United Kingdom on 2 February 2016*

I had a stuck transmission filler plug that had been done up overly tight by a garage gorilla, who admitted to use a copper washer to stop it binding. Whilst trying to undo the bolt its torx head started to give, rather than strip it I purchased and I applied the Comma release oil to the stuck bolt and left over night, it made no difference, so I tried several more applications, even running the vehicle for a long journey hoping heat would give it greater impact. But it really did not make that much difference and in the end I had to get a set of heavy duty extractors to free the bolt.I have used it on my wife's car door hinges and it stopped them squeaking but then so would 1 in 3 or WD40. If in the future I find an application it really work upon I will amend my review.
