I have not been able to find, in my 54 Chevrolet Truck Shop Manual, where it actually says how much oil the engine takes. All my Motors Manuals state 5 qts for all 216 and 235, 6 qts if you have the canister filter, these are the passenger car manuals. Is it safe to say that all 235 and 261's take 5 qts, 6 with filter, irregardless of the dipstick tube and dipstick configuration? Or could my 261 have a higher capacity oil pan?
