LIQUI MOLY Motor Oil Saver | 300 ml | Oil additive | SKU: 1802

Had a slight leak from the pump housing on my Corsa - poured this in and ran it like instructed and forgot all about it. Four months later the is no evidence of the leak so it was well worth the £10 gamble.

Did the job as intended

Excellent 👍

I have a 2012 VW Touareg with a 3.0 TDI engine. Some engines were known to develop a slight leak at the bottom of the bellhousing between the engine and the auto gearbox. This was sometimes put down to either a rear main seal leak, or the fact that thread locker fluid had been omitted from the flywheel fixing bolts during manufacture. I noticed a small leak at this point, and read some good reviews about this Liquimoly product, so decided to give it a try.I added a bottle and a half to the engine oil during a recent oil and filter change, as this engine takes 7.7 litres. Around 200 miles since, I have noted that the leak has almost completely stopped. I'll check again in a while, at which point I'm hoping to award the product 5 stars!I was dreading the prospect of having the engine and gearbox removed to replace a rear main seal, and all the cost and hassle that entails. If that wasn't the problem, this product may have helped to plug the weeping oil leaks via the bellhousing/flywheel bolts. Time will tell, but so far, so good.Even if I have to repeat the dosage in the future, it's still cheaper than an engine and gearbox removal job!

Looks like a good product. It is not like the normal treacle type stuff used to stop engine oil burning. Used it after flushing and replacing the oil and filter. After monitoring after the first 100 miles, the oil consumption has slowed. Will now continue to monitor every 100 miles.

It really works

I had a small leak somewhere in the engine that was not readily accessible, evident by some spots of oil on the drive. Did this fix my issue? No but it might fix yours. I can't say the engine ran smoother or quieter either but it certainly was easy to use if that helps. Just pour it into your engine and run the car as usual. I did try another brand at a similar price point; that worked in better for my situation, that was a "professional Wynning" solution if you get my drift. However the hundreds of good reviews for this product must have some credibility and it's no doubt a good product, just not for me.

BMW are known for their weak seals. So when the MOT mentioned a slight leak, we checked the costs involved for replacing the seals which were high due to labour costs. Decided to try this 1st before expensive repairs. All seems good so far but it's needs several weeks to run through the system
