Important Note Regarding Oils, Additives, Aerosols & Liquids

This listing may contain a product with transport restrictions. Items containing oils, additives, aerosols, adhesive or other liquid/chemical-based products may be subject to shipping restrictions depending on their current warehouse location, carrier requirements, and applicable transport regulations.

Some liquid and aerosol products are restricted for air freight or certain road freight routes and may require alternative transport methods or dispatch from a specific warehouse. While the majority of these items ship without issue, these factors can occasionally affect available shipping options or delivery timeframes.

If you are working to a tight deadline, require urgent delivery, or are unsure whether a product can be shipped to your location, we recommend contacting the StreetFX team prior to placing your order so we can confirm availability and the most suitable freight option.

Reference Information

Motor Oil Additive, ZDDP, Engine Break-In, 4 oz., Each

Protect your camshaft and flat tappet lifters with a bottle of Mr. Gasket Zinc Engine Oil Additive. Modern motor oils no longer include the zinc, ZDDP, and extreme pressure additives needed to properly lubricate the cam and lifters. One 4 oz. bottle effectively treats 5-7 quarts of oil to prevent scuffing and galling, with protection for the valvetrain on your muscle car, hot rod, street rod, or classic car. This fluid is compatible with synthetic, petroleum, and blended motor oils. Add a bottle to the crankcase of your engine at each oil change. (Use with Pre-ODB and off-road vehicles.)
