MPG X-Caps vs Bottled Fuel Additives: Format and Label Differences
Quick Answer
MPG X-Caps use a solid caplet format placed in the fuel tank. Many other fuel additives use a measured liquid. The useful comparison is product purpose, treatment ratio, fuel compatibility, and directions rather than package shape alone.

MPG X-Caps use a solid caplet format placed in the fuel tank. Many other fuel additives use a measured liquid. The useful comparison is product purpose, treatment ratio, fuel compatibility, and directions rather than package shape alone.
Caplet format
MPG X-Caps dissolve in fuel after being added to the tank. Current MPG materials provide formats for personal vehicles, commercial vehicles, and small engines.
Liquid format
Bottled additives use a measured volume. One bottle might treat one tank, several tanks, or a specified number of gallons.
Product purpose matters more
Cleaner, stabilizer, octane-related additive, anti-gel, lubricity additive, and multi-function formulas serve different jobs. Compare the stated purpose first.
Treatment ratio
Follow the exact MPG directions for X-Caps and the exact manufacturer directions for a bottled product. Do not estimate doses from package size.
Manufacturer claims
MPG makes performance statements for X-Caps. ESX identifies those as MPG claims and keeps the independent comparison focused on format and label reading.
