Frost is proud to inform you that our Ethomix (Z555) is now endorsed by the Federation of British Historic Vehicle Clubs (FBHVC) as a fuel additive for protection against corrosion in metals.
Due to the addition of Ethanol in petrol, it is essential to use a corrosion additive for nearly all pre 1996 engines. Frost Auto Restoration Techniques introduces an additive to protect against the harmful impact of Ethanol blended petrol. Frost Ethomix additive will combat the significant damage Ethanol blended fuel can cause to cars, motorcycles and non-road equipment that do not have compatible fuel systems. Ethomix is formulated to prevent corrosion in fuel systems and internal engine components, gum and resin build-up, clogged carburettors, injectors, filters and fuel lines, plus aggravation of water and moisture problems in fuel storage or unused engine situations.
- Prevents corrosion in the fuel system & internal engine components
- Protects against gum & resin build-up & carbon deposits
- Prevents clogged carburettors, injectors, filters & fuel lines
- Compatible with 2 & 4 stroke petrol engines
- Stabilise Ethanol-blended fuels
FAQsQ: Will the Ethomix additive, when added to pump petrol, counteract all the problems Ethanol blended fuels will cause to Classic Cars?
A: We think we have a pretty good product, but regrettably it will not cure all the ethanol issues.
Q: Can you provide details on how Frost Ethomix protects against the effects of ethanol?
A: Frost Ethomix additive contains several functional components, a pHe buffer to control acid formation, a filming corrosion inhibitor to protect ferrous metals and a polymeric dispersant which provides the detergency claims.
Q: What tests have been carried out to prove it works?
A: Frost Ethomix has been tested using industry standard test methods, ASTM methods for corrosion and pHe and CEC test protocols for detergency performance.
Not only that, in 2012, Frost Ethomix passed the fuel stability additive test programme and now endorsed by the Fenderation of British Historic Vehicle Clubs (FBHVC) as a fuel additive for protection against corrosion in metals.
Q: In particular, can Frost Ethomix prevent galvanic corrosion in carburettors for example where electronically dissimilar metals are used?
A: Frost Ethomix will not protect against galvanic corrosion as this is a metallurgy issue. There are no corrosion inhibitor additives which can overcome galvanic corrosion.
Q: Will Frost Ethomix mix with other additives?
A: Frost Ethomix additive is compatible with leaded petrol and lead replacement additives.
Q: What materials should be changed or avoided (or regularly checked)?
A: Zinc and galvanised materials, Brass, Copper, Lead / tin coated steel. (Aluminium), Buna-N (seals), Neoprene (seals), Urethane rubber, Acrylonitrile-butadiene hoses, Polybutene terephthalate, Polyurethane, Nylon 66, Fibreglass-reinforced polyester and epoxy resins, Shellac, Cork.
