I've also tried the Wynns product , but this was too viscous and made the steering stiff, which the Granville product didn't. However, make sure you check where the leak is coming from first. If its past a rubber seal then this is the product to use. If however, its from a metal pipe like the power steering cooler, no stop leak will fix the latter. One of my cars had such a cooler , which was a metal pipe running infront of the power steering unit or even plumbed infront of the radiator. It had simply corroded through due to rust and needed replacing . The stop leak causes the rubber seals to swell and unlike a radiator stop leak, does not plug holes in corroded metal pipe, regards Dick Turbo **Q: Will it work on my Vauxhall’s insignia power steering** A: It worked on my Fiat Ducato Van i had quite a bad Leak on the steering rack so i thought i would spend £10 to see if it worked Rather than £1000 for a new steering rack. it takes a while to get through so there are not instant results. may be an idea to remove as much fluid as you can from the reservoir then fill up with the stop leak then top up with fluid if necessary **Q: Is it ok for a 96 Bentley Turbo R** A: It's fine for any car that takes power steering fluid. Mine is a Mercedes 430ML. The power steering pump was noisy. My mechanic said to try this before replacing the pump. It works by softening the seals up again. In mine the noise has gone and everything works beautifully. **Q: 10k boost power steering stop leak is it ok for Ford Focus** A: Yes. 100%. ## Frequently Bought Together - Granville 1440A 10K 375ml Boost Stop-Leak Power Steering Fluid - Granville 1813A 500ml Power Steering Fluid and Condition --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/48069340-granville-1440a-10k-375ml-boost-stop-leak-power-steering-fluid](https://www.desertcart.us/products/48069340-granville-1440a-10k-375ml-boost-stop-leak-power-steering-fluid) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-18*
