Lucas Oil40278 Engine Stop Leak - 946ml

Had quite a bad leak on my old car and before i put it in to have an expensive job done on the engine i thought id try this. Poured it into a cold engine,ran it on idle for a 15 mins,turned the engine off and left it until the next day hoping it had worked. Boy did it work,not a single drop from a once leaking engine,i was amazed and still no dripping oil,its a fantastic product!!

Works well, bought for mums friend and it works.

Didn't stop small oil leak but did make engine seem quieter .

Good

This is a great product for stopping leaks and easy to use good value for money

After having a quote for over £700 and then be told it might not work,this product was worth a try, a leak above bell housing.Half a bottle and a 160 mile trip up down mway it seems to have worked, you have got to engine run or waste time

Poor Fran, she's a 2011 1.3 Yaris with 115 thousand miles on the clock. There's been a terrible rattling sound each time the engine was started. After adding this engine oil, I'm happy to report that Fran is rattle free and she's feeling great to be driven around again. Its early days but I hope this product keeps our Fran fit and healthy.

Still leaking the same amount, no efect
