| DOT5.1 and DOT 5 are DIFFERENT!
Unlike a silicone-based DOT5, DOT5.1 is glycol based just like the conventional DOT3/DOT4. It means DOT5.1 does NOT absorb water quickly like DOT5 and does NOT require the total changeover of the brake lines or hoses, and can be used just like DOT3/DOT4. In addition, DOT5.1 has a higher boiling point and good Viscosity at low temperatures. |

【Come with Fluid change reminders.】 Replace the whole amount every two years (1 to 1.5 liters).The date on the reminder sticker is just an indication. The oil change intervals may vary depending on the conditions under which the vehicles are used. Normally 1 liter of brake fluid is needed to replace the whole amount in the brake system. Please refer to the owner’s manual of the vehicle. |
