Berryman B-12 Chemtool Carburetor, Choke & Throttle Body Cleaner comes in three different formulas and up to three different sizes for a total of seven unique part #s.
For states without VOC restrictions, including TX, OK, AZ, FL, and the Deep South, we offer part #0110 part #0117 and part #0120, which are 10-, 16-, and 20-oz versions, respectively, of our standard B-12 formula.
For states with intermediate VOC restrictions, including many in the Upper Midwest and New England areas, we offer part #0117-45 which is a 16-oz product.  This is the only size for this formula.
We also offer part #0110C, part #0117C and part #0120C , which are 10-, 16-, and 20-oz versions, respectively, of our lowest-VOC formula of B-12.  This “C” product is intended for use in states with the most restrictive VOC regulations, including CA, CO, NY, and UT.
Lastly, when comparing sizes, make sure you’re also making note of the part #s on the back of the cans at the very top.  For instance, 0110 and 0117 are the same formula but different sizes, while 0110 is not the smaller version of 0120C.
