Correct oil capacity 1098cc Minor engine

[LanceNZ]

Hi All,
Can anyone confirm the correct oil fill capacity (after sump drain and filter replacement) for a 1098cc Minor engine?
I have checked various sources and as they say "a man with 2 clocks never knows the true time"! Some references say 6 pints (3.4l), another says 6.5 pints (3.7l) and the online Castrol / Penrite oil recommendations state 3.9 litres.
And before any of you say "check the dipstick", I have no way of knowing which is the original dipstick for the car. When rebuilding the engine from a pile of parts, I had 4 different dipstick to choose from!
So, what I have done is drained and replaced filter (after running in oil) and have currently added a measured 3.5l of oil @ ambient temp (20 deg C). I will then "adjust" the dipstick height to suit the correct oil level - BUT for this I need to know what it should be!!!
If any of you have a cast iron, absolutely accurate, as per the bible capacity please let me know!

BTW, I was shocked to find that my company (BMW Group New Zealand) had Castrol Classic oil in stock in our warehouse! May be old stock, but I get it a cost AND it comes in a cool tin!

Many thanks
Lance

Hi. The original BMC Drivers Handbook that came with my 1966 Traveller (1098cc 10MA engine) gives "Engine Sump 6 1/2 pints (3.69 litres) (including filter)". Hope this helps.

I concur
3.7 litres stated as filter and sump total capacity

Lovely can and no rust on the base!

What size is that can? 1 gallon? 4 litres? Or?

5l I think - suspiciously similar to the ones you can get a Wilko for £16

[LanceNZ]

Thanks all - yes its a 5 litre can.
I'll put another 200ml in to get it to 3.7 and will set the dipstick height to match - job done!

[Bidz]

Is it different with a spin-on filter?

[les]

When you have the correct amount in, why don't you try all 4 dipsticks and see which one shows full, which would indicating the right one to use?

[dalebrignall]

i just fill it to the full mark about 3.5 litres and just add a bit more till its full , you get to know after a while , just dont over fill , that can do more harm than good

[les]

He doesn't know where the full mark should be! Hence his question.

[dalebrignall]

did not read the post correctally

[Bidz]

So I filled mine with 3.7l and it reads above the max mark on the dipstick!

[les]

Run the engine, let the oil circulate, switch off, wait, and check again.

But which one of the 4 dipsticks that you said you had?

[panky]

It's Lance with the dip stick collection

[Bidz]

I do have a collection of dipsticks. They're not for engines though...

[LanceNZ]

Reminds me of the old 70's show "The Dukes of Hazzard" - "Enus you DIPSTICK!!!"

[irmscher]

Measure your dipstick with another one from a fellow Minor owners engine

Hopefully it wont lead to a case of dipstick envy
