Works. Had a small leak and i flushed the engine, changed the oil adding the stop leak with the new oil. Ran the engine as instructed to, no leaks and its been over a month. Was recommended to me, and it was worth it.

I've bought a lot of products before but they didnt totally stop the leakage as what this product did.

I put the SO-1 into my engine and turned on the engine sat there for 20mins then drove for 20miles got home and checked my dip stick still where it was when I started my drive, now a few days before I had changed my oil, the next day I replaced my front brake pads I noticed my lower wishbone was very shiny it was soaked in oil, now it isn't, so SO-1 must have worked caramba! Happy me, and no I did not think it would work and now think £22.00 was money well spent, well done Bars Leaks!

Magnífico. Tengo una de mis motos con casi ya 40 años y algunas fugas de aceite motor severas. No era una gotita, era ya casi pequeños charcos. Decidí probar este mejunje y el resultado es de 10. Han desaparecido por completo. No hay fugas ni gotas ni nada de aceite ya bajo la moto. Cuesta creer en estos productos milagrosos, de hecho no creía en ninguno pero como tenía mucha pereza y poca pasta para levantar el motot y gastar más de 200€ en juntas decidí probar por las reseñas positivas que leí a ver que tal en mi moto y si! Funciona 🙂 Apto para motores con embrague en baño de aceite o sea que lo puedes poner en tu moto sin problema... 😜
