If the 261 block is shared with cars and trucks, then does the oil pan dictate capacity? Cars typically 4qt plus filter, trucks 5qt plus filter. | | | | | Joined: Jun 2004 Posts: 8,597 Riding in the Passing Lane | | Riding in the Passing Lane Joined: Jun 2004 Posts: 8,597 | All the old Stovebolt engines took 5 qts. plus one for the filter. The best way to make sure the Canadian version is the same is drain it & put in 4 qts. & check the dipstick.

They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | | | | Joined: Jan 2016 Posts: 709 'Bolter | | 'Bolter Joined: Jan 2016 Posts: 709 | I put in 5L, since it has a filter. That's 5.2Qt and it's only to the 'low' mark. | | | | | Joined: Mar 2007 Posts: 4,215 Moderator | | Moderator Joined: Mar 2007 Posts: 4,215 | I had that Pontiac 261 as well. Just be careful not to mix up the US quarts with imperial quarts. A 5 litre jug didn't fill mine, must be closer to 6 litres but I went by the dipstick. | | | | | Joined: Jan 2016 Posts: 709 'Bolter | | 'Bolter Joined: Jan 2016 Posts: 709 | Good to know Leo, I have a Pontiac manual for a '58 and it says 5qt with filter. From what you say, my dipstick might be telling me the truth... | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | All the old Stovebolt engines took 5 qts. plus one for the filter.

George George (and others), I dimly recall that my 1960 261 from a C60 school bus had an oil pan that was deeper in the rear, compared to my 1954 1/2 ton truck engines. Is that possible? I also dimly recall that the oil dipstick was longer for/from that 261. Am I dreaming on this one, too? I will try to look these up in a Master Parts Catalog. | | | | | Joined: Jan 2016 Posts: 709 'Bolter | | 'Bolter Joined: Jan 2016 Posts: 709 | Also, how much oil is typically required to go from 'low' to 'full'? 5qt gives me 'low', perhaps one more litre would fill it? | | |
