    A: We normally recommend 1 oz to 10 gallons for normal automotive use. You can not over treat with the product, so a stronger mixture is ok.

It worked!

5 months ago
This worked on my son in laws pressure washer. Follow the directions in the videos, do not follow the directions on the bottle. Drain the gas tank, drain the carburetor. Add MIB and work it into the carb, let it sit at least overnight. Drain the MIB out of the gas tank and carb, add fresh gas and fire it up.

Yes, I recommend this product.

Best stuff ever!

6 years ago
Had a brand new push mower. It was only run twice last fall. I ran the gas out and parked it for the winter. Went to mow the lawn yesterday and it wouldn’t start. No gas getting to the carb. Bought the MIB and squirted a bit directly into the carb and put a bit in the tank. Waited about 30 minutes and it fired right up!
