Stop in for a cup of coffee

trying to figure why 5qts of this is $22... but 5qts of GTX classic (with zinc) is $33.. seems like a big jump for some zinc.. which i don't need anyway, gonna change my oil since my carb problems have probably turned it to water.. plus i have no idea how much oil is in it.. i need to fix the dipstick issue

I thought you were going to ask why the 5 quart jug was $22 but 5 one-quart bottles was $33
