Great service & priceReviewed by Rick.jasper on 14 Oct 2021

We found Mylor Chandlery first class on price & delivery on this product. Regarding the Marine 16 Diesel Complete Treatment we have used this product and found it does what it says on the bottle & advertised keeping our boat free from diesel bug. Due to the above I would not hesitate in using Mylor Chandlery or this product again.

Never Any ProblemsReviewed by Chrisodixon on 26 Oct 2019

I have been using this product on my boats for years. All of my boats are steel built and moored on the inland waterways. My last boat had the fuel tank built onto the hull! I buy fuel from where ever I am on the network. I have never had any fuel problems, which I put down to; cleaning the water separator each year AND always adding Diesel Fuel Complete when refuelling.
