Granville 1440A 10K 375ml Boost Stop-Leak Power Steering Fluid

Don't listen to the negative reviews, if used correctly this stuffs brilliant. So firstly,if you have a massive leak or a split hose this stuff won't work, it's not a miracle in a can ! Its not a substitute for replacing knackered and completely worn out parts. However, if you have a drip drip type leak then this could do the job but....I suspect a lot of ppl have been tipping the entire can in to their systems then becoming dumbfounded that the leaks got worse! This stuff is water thing and contains a solvent that revitalises seals , a little drop will do you! Start with just under a quarter of the can make sure the fluid is on the stick. Start car and rotate steering a dozen times, then take for a 15 mins drive , make sure there are some corners and junctions, park car , check for leaks the next day , add a touch more if required

I’ve got a slight leak on power steering that makes it a bit stiff when 1st starting car. After about 5 min it usually free up and normal. I’ve tried several leak stop etc and no good. Tried this and after about 1 week of driving its loads better on steering when 1st starting car

It worked for me , previously the ground would get damp with oil after a drive and other bits below power steering hose. Now all bone dry , I highly recommend using a syringe to suck up oil and then putting whole can down there afterwards. Hopefully this will be a long term fix and not just a temporary fix . Edit: 2 months on and still not leaking , brilliant. Edit: over 6 months now and still not leaking

We own a 2005 Nissan Murano, the parts are no longer supported by Nissan so rather than pay £500 for some replacement parts from Europe I thought I'd give this a try. It did work for a couple of weeks but maybe the leak is too large and the screeching is back and the steering stiff once more. Not a big deal as we have bought an electric Mercedes now as the Nissan was close to becoming ULEZ non-compliant. Anyone outside the London area want to buy a nice Murano? Just had new radiator, brakes, exhaust, fan belts but may need a power steering hose!

Previously used similar items to try and cure my power steering leak to no avail. I was loosing roughly half a bottle a month. And was to cheap to take it to a garage lol. Purchased this down to the good reviews and I’m happy I did. I changed the power steering fluid with fresh stuff and added this product. Over a few weeks I did loose some fluid however noticeably less then previously. After 3 weeks or so I topped the fluid back up to the mark and since I haven’t lost a single drop of fluid . Great product and done what a lot of other products couldn’t .

Well, this did not work for the power steering leak on my transit custom. This actually made the leak worse which then forced me to put the van in to a garage. Two power steering pipes replaced and leak sorted. Well at least I tried this, but did not work in my case.

I was doubtful but in view of the problem and cost of dismantling the car it was worth a try. In a couple of weeks it stopped fluid leaks and the car drives fine. (1998 Volvo 940)
