Q: Are R134a and AutoZone 12oz cans the same weight?

A: Bought 5 12oz cans also had a 12oz can from autozone. the two clearly are not the same weight. but even a little short on weight it is 1/2 the price of normal R134A so all in all 3 stars. Helpful? Get specific details about this product from customers who own it.
