Remove associated cap and foil seal, if new, then squeeze bottle to fill this measure. Additive transfers from main bottle to measuring cup. Pour measured amount (10mL) into bulk fuel container. Repeat procedure to give correct dilution with fuel of 10ml (one measure) per litre of fuel. Shake bulk storage can to mix before adding to mower fuel tank. **Q: will one treatment with this product really keep my store of 30L of petrol good for 3 years?** A: it will certainly keep it good for a year,never had a reason to keep fuel any longer. **Q: What is the difference between 992381 and 992380 please** A: Size: the 992380 is 100ml and the 992381 is 250ml ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fuel addative *by M***N on 22 June 2026* Very good product for a reasonable price ### ⭐⭐⭐⭐⭐ Wo4k fine *by P***N on 12 June 2026* Seems to work well as it was recommended by the lawn mower manufacturer ### ⭐⭐⭐⭐ GREAT PRODUCT *by J***R on 26 May 2014* Before retirement last year, I had spent a long time studying the claimed benefits of fuel additives as part of my job, and came to the conclusion that there are indeed very tangible benefits to be obtained by the end user for DIESEL engines, which was my speciality. Coming from that background, I was therefore confident that it would be possible to improve the "keeping" quality and performance of forecourt petrol. Petrol goes "off" quite quickly. I have used this stuff for about 10 years . I can honestly say that it does improve the "keeping" quality. Prior to using it, there was no chance my Lawnmower engine (Briggs & Stratton) would start in the Spring with the previous season's petrol in. Now, I can be sure it will start with a couple of pulls. Similarly, my 2 stroke Mantis engine now starts first time, every time. Not so though with my Honda Rotavator engine. It starts OK, but won't run for long with the old "treated" petrol. Only new petrol keeps it going. So not a universally successful solution for me, but it's so inexpensive to use, it's worth giving it a go. This stuff does work with petrol stored over Winter - at least with my Lawnmower engine (Briggs & Stratton) There was no chance of it starting in Spring with old petrol, but now it goes first time. Have used it for many years now. Not the same with my Honda rotavator engine though - still have to buy new petrol in the Spring ## Frequently Bought Together - Briggs & Stratton Fuel Fit Additive/Stabiliser. 992381 - Briggs & Stratton 100006E 4-Stroke Lawn Mower Engine Oil SAE30, 1.4 l, Black, 1.4 Litre - CarPlan TPH005 5L Fuel Can, Unleaded Petrol (Green) --- ## 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.co.th/products/47954628-fuel-fit-additive-stabiliser-992381](https://www.desertcart.co.th/products/47954628-fuel-fit-additive-stabiliser-992381) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-07-08*
